Is Supplementation Important For Hospitalized Patients?

Why Does Supplementation Matter During Hospitalization?

Author: Dr. Stephen Chaney

Hospitalized Elderly PatientI have often said that age doesn’t necessarily bring wisdom, but it does bring perspective. When I first started teaching medical students in the early 70’s, the idea that optimal nutrition was important for hospitalized patients was new and exciting.

A series of groundbreaking papers documented that many patients, especially elderly patients, were in poor nutritional status when they entered the hospital. For these patients optimizing their nutrition while they were in the hospital and shortly thereafter:

  • Reduced mortality and increased recovery from whatever treatment they were undergoing.
  • Reduced the incidence of sepsis (systemic infection) and other severe side effects of the treatment.
  • Reduced recovery time in the hospital.
  • Allowed them to return to their normal daily activities more quickly after they left the hospital.

Those discoveries revolutionized medicine. Every hospital now provides tube feeding and iv infusions for very ill and nutritionally compromised patients. And these innovations have improved the effectiveness of hospital care.

So, when I saw a recent paper (GE Baggs et al, Clinical Nutrition, 42: 2116-2123, 2023) with the title “Impact of a specialized oral nutritional supplement on the quality of life in older adults following hospitalization”, my initial thought was this was old news.

But then I read further. You see, feeding tubes and iv infusions are very effective. But if you or a loved one has ever been hospitalized for a serious illness or accident, you also know they are very expensive.

When I read this study, I realized they were talking about a less expensive option, the equivalent of providing these patients with a multivitamin and a protein shake providing certain critical nutrients. That got my attention.

How Was This Study Done?

clinical studyThis study utilized data from something called the NOURISH [Nutrition effect On Unplanned Readmissions and Survival in Hospitalized patients] trial. This trial enrolled hospitalized older adults with malnutrition. As the title of the trial suggests, this study tested the effect of the nutritional intervention I will describe below on unplanned readmissions after hospitalization (which you want to be as low as possible) and survival after hospitalization (which you want to be as long as possible).

That study reported that hospitalized patients who received the prescribed supplement experienced:

  • Improved nutritional status.
  • Improved survival and reduced readmission after leaving the hospital.

This study re-analyzed the same data set to determine whether the same patients also experienced improved quality of life. Here are the specifics of the study:

Elderly (average age = 78) patients who were recently admitted to the hospital with a diagnosis of congestive heart failure, acute myocardial infarction (heart attack), pneumonia, or COPD were screened for nutritional status. From this group, 622 patients with moderate or severe malnutrition were selected for the study. Patients with this combination of age, severe cardiopulmonary disease, and poor nutritional status generally have poor outcomes and increased risk of readmission.

The patients were randomly split into two groups. One group received standard care. The second group received a beverage containing 20 grams of protein, 1.5 grams of beta-hydroxy-beta-methylbutyrate (HMB), plus vitamin D and other essential micronutrients.

[Note: HMB is a metabolite of the amino acid leucine. And, like leucine, HMB stimulates an increase in muscle protein synthesis, reduces loss of muscle mass during hospitalization, and enhances the regain of muscle mass during recovery. HMB and leucine give essentially equivalent results.]

The second group received a placebo beverage containing 12 grams of carbohydrate, 10 mg of vitamin C, but no protein, HMB, or other micronutrients.

Patients were instructed to drink 2 servings of the beverage a day during hospitalization and for the first 90 days after discharge from the hospital.

On the day they were discharged from the hospital (day 0) and on 30, 60, and 90 days after discharge the patients met with trained coordinators who administered questionnaires assessing their quality of life.

Is Supplementation Important For Hospitalized Patients?

Hospitalized Elderly Patient RecoveringWhen compared to the placebo, the supplement described above provided significant improvements in:

  • General health on days 0, 30, 60, and 90 after leaving the hospital.
  • Mental health on days 60 and 90 after leaving the hospital.
  • Vitality and social functioning on day 90 after leaving the hospital.

In addition, there was a trend towards improvement for:

  • Physical functioning, reduced body pain, and mental health-related role limitations [for example, taking care of a spouse].

The authors concluded, “Among malnourished, hospitalized patients (aged ≥ 65 years), supplementation with S-ONS [their acronym for the supplement used in this study] during hospitalization and 90 days post discharge resulted in improved quality of life. These benefits complement survival benefits previously shown in the NOURISH trial analysis.”

Why Was This Supplement Effective?

You will notice that the beverage used was relatively high in protein (20 grams) and included added HMB to help increase muscle mass. It also contained a variety of micronutrients.

There are two reasons for this design.

  • You have heard the saying, “It’s all downhill after age 30.” With muscle mass the downhill slide starts around age 50. This age-related loss of muscle mass is referred to as sarcopenia.

Sarcopenia can be slowed by resistance training plus diet or supplementation that provides around 20 grams of protein plus either leucine or HMB 2-3 times a day.

However, many older adults have trouble fixing healthy meals and end up protein and micronutrient deficient.

  • Severely ill patients enter what is referred to as a catabolic state. They break down their muscle and energy stores at a high rate. This is also true for patients recovering from major surgery or trauma.

The catabolic state dramatically increases protein and calorie needs just to prevent the body from cannibalizing its own tissue. Again, previous studies have shown that a protein supplement providing around 20 grams of protein and either HMB or leucine can slow this process.

What Does This Mean For You?

QuestionsThere are two major take home lessons from this study.

1) Who needs supplementation?

I have covered this topic in previous issues of “Health Tips From the Professor”, but let me summarize the key points here.

  • Supplementation can fill the gaps in an inadequate diet. Multiple studies have shown that most Americans get inadequate levels of one or more essential nutrients from their diet. And restrictive diets ranging from vegan to keto create additional nutritional deficiencies.
    • And, for this purpose, supplementation need not be complicated. A multivitamin and a plant protein shake to replace some of the animal protein in the typical American diet would suffice.
  • Supplementation can reduce the risk of certain chronic diseases. We should not think of supplementation as a “magic bullet”, but I do recommend it as part of a holistic approach to wellness.
    • In this case supplementation starts with a protein shake and a multivitamin, but often includes targeted nutrients such as omega-3s.

But this study reminds us of another key point about supplementation.

  • We should supplement before we need it most. The seniors in this study were already “behind the 8 ball” when they were admitted to the hospital because they were malnourished – something that likely could have been prevented with a simple program of supplementation and exercise.

This is a lesson that applies to all of us.

    • Chronic diseases like high blood pressure, diabetes, and cancer “sneak up on us”. They often develop years before we or our doctors recognize them. Studies show that diet and supplementation reduce the risk of developing these diseases, but they are much more difficult to reverse once you have them.
    • Most hospitalizations are unplanned. And if we enter the hospital with optimal nutritional status, the outcome of our treatment is much better than if we enter the hospital in poor nutritional status.
    • Colds and viruses strike without warning. We are much more likely toward them off or recover more quickly if we are in good nutritional status when we are exposed.

2) What kind of supplement do we need? Don’t misunderstand me. There are times when tube feeding and iv infusions are absolutely essential for some hospitalized patients. 

But this study showed that a well-designed protein supplement containing the essential micronutrients was sufficient for most elderly, malnourished patients hospitalized with severe cardiopulmonary diseases.

  • The formulation used in this study was produced by a pharmaceutical company. However, any high-quality protein supplement providing 20 grams of protein with added leucine or HMB plus a multivitamin supplement should provide the same benefits at a lower cost. The multivitamin could be in tablet or powder form.
  • The catabolic state associated with hospitalization also increases energy requirements. The protein supplement used in these studies had 350 calories and 44 grams of carbohydrate.

Most commercial protein supplements are designed for weight loss or weight maintenance and have fewer calories. So, for hospitalized patients extra calories would need to be provided in the form of foods containing healthy carbohydrates and fat.

The Bottom Line 

Recent studies have shown that providing elderly, malnourished patients with a simple, inexpensive supplement regimen during and following hospitalization leads to better outcomes and better quality of life for the hospitalized patients. These findings illustrate two important concepts about supplementation:

  • The time to supplement is before you need it. Most hospitalizations are unplanned, and your outcome will be much better if you enter the hospital in optimal nutritional status.
  • Supplementation need not be complex and expensive. The supplement regimen used in this study is equivalent to a high-quality protein supplement with added leucine or HMB plus a multivitamin.

My answer is, “Yes, as long as you share only the article without any additions or alterations. In particular, you should avoid adding any mention of your company or your company’s products. If you were to do that, you could be making what the FTC and FDA consider a “misleading health claim” that could result in legal action against you and the company you represent.

Which Vitamins Reduce Breast Cancer Risk?

How Can You Reduce Your Risk Of Breast Cancer?

Author: Dr. Stephen Chaney 

Breast cancer is scary. The good news is that treatment has gotten much better. Breast cancer is no longer a death sentence. But most women would prefer to avoid breast cancer surgery, radiation, and/or chemotherapy if they could.

Could something as simple as supplementation reduce your risk of developing breast cancer? If so, which vitamins should you be taking? Or, put another way, which vitamins reduce breast cancer risk?

If you ask your doctor, they will tell you, “Supplementation is a waste of money. Vitamins don’t reduce your risk of getting cancer.” And they will be correct! That’s because these are the wrong questions.

Let me explain. These are “one size fits all” questions. Studies to answer these questions start with healthy women and asks if vitamin supplementation reduces breast cancer risk for all of them. The answer to that question is, “No”. Multiple studies have confirmed this.

But the truth is more complicated. We should be asking, “Who benefits from vitamin supplementation”, instead of, “Does everyone benefit from supplementation?”Supplementation Perspective

I have summed up this concept with the Venn diagram on the right. Every woman does not need supplementation. But those with poor diet, increased need, genetic predisposition, and/or certain diseases may benefit from supplementation. That is why we should be asking, “Who needs supplementation?”.

Unfortunately, while this concept of individualized treatment has led to dramatic advances for cancer drug development, it has been virtually ignored for studies on supplementation and breast cancer risk.

The current study (H Song et al., Nutrients, 14: 2644, 2022) is an exception. It asks whether obese women who wish to reduce their risk of breast may benefit more from certain micronutrients than women of normal weight.

How Was This Study Done?

Clinical StudyThe data for this analysis came from the KoGES study. This was a study administered by the Korea Agency for Disease Control and Prevention between 2004 and 2016. It was designed to provide a scientific basis for personalized prevention of chronic diseases in the Korean population.

Of the 211,721 participants enrolled in the original KoGES study, this study included data from 41,593 women who:

  • Underwent a health examination at 38 health examination centers upon enrollment between 2004 and 2013 and a follow up health examination between 2012 and 2016. The average follow-up period was 4.9 years.
  • Were cancer-free when they enrolled in the study and developed breast cancer prior to their follow-up health examination.
  • Had reliable diet data.

Dietary intake was based on a food frequency questionnaire administered during their initial health screening. Dietary intake of 15 micronutrients (calcium, phosphorous, iron, potassium, vitamin A, sodium, vitamin B1, vitamin B2, vitamin B6, niacin, folic acid, vitamin C, vitamin E, zinc, and cholesterol) and 4 macronutrients (energy, protein, fat, and carbohydrate) was determined from the food frequency data and compared to the Korean Dietary Reference Intakes (KDRIs). [Note: The Korean DRIs are slightly different than US standards.]

  • The women were then divided into two groups based on whether they consumed more or less than the Korean DRIs for each nutrient.

Which Vitamins Reduce Breast Cancer Risk?

Vitamin SupplementsThere were two major findings from this study.

1) When the investigators grouped all the women in the study together:

    • none of the 15 micronutrients and 4 macronutrients analyzed in this study influenced breast cancer risk.
    • This confirms most previous studies that have been designed as a “one size fits all” study. So, if your doctor was relying on this kind of study, they were technically correct in saying that vitamin supplements don’t appear to reduce breast cancer risk.

2) But when the investigators separated the women by weight, an interesting dichotomy was observed:

    • For obese women (BMI ≥ 25 kg/m2):
      • Vitamin C intake above the recommended Korean DRI (100 mg/day) reduced the risk of breast cancer by 46%.
      • Vitamin B6 intake above the recommended Korean DRI (1.4 mg/day) reduced the risk of breast cancer by 52%.
    • For women of normal weight (BMI < 25 kg/m2) neither vitamin C nor vitamin B6 had any effect on breast cancer risk.

The authors concluded, “In obese women, exceeding the recommended daily intake levels of vitamin C and vitamin B6 was associated with a lower risk of breast cancer. However, other micronutrients were not associated with breast cancer risk in these women.” [Note: Supplement use was not included in the diet survey, so above recommended intake of C and B6 was from foods consumed, not from supplements.]

What Does This Study Mean For You?

Questioning WomanThis study is a perfect example of why we should be asking, “Who benefits from vitamin supplementation”, instead of, “Does everyone benefit from supplementation?”

In terms of the Venn diagram I introduced above, some people consider obesity a disease.

But whether you consider obesity a disease or not, it does increase the need for many nutrients. So, it is conceivable that extra vitamins C and B6 might provide benefits in obese women that are not seen in non-obese women.

This is, of course, a ground-breaking study. It is the first study of its kind and deserves to be followed by other studies to confirm this observation. Ideally, these studies would test whether the same effect is seen in other population groups and determine the optimal dose of vitamin C and B6 to reduce breast cancer risk.

However, I am not optimistic that these studies will be done. It is easy to get funding for the “do vitamin supplements benefit everyone?” studies that confirm the existing prejudice against vitamin supplementation.

It is much harder to obtain funding for “who benefits from vitamin supplementation?” studies that challenge the existing paradigm. But these are the kind of studies that are needed most.

How Can You Reduce Your Risk Of Breast Cancer?

As I said, this is the first study of its kind, so you could consider the results as preliminary. However, assuming it might be true:

  • I do not recommend megadoses of vitamins C and B6. The above average intake of C and B6 in this study came from food alone. And we do not have any dose response studies that might define an optimal dose of C and B6.
  • I do recommend balance. Based on this study, multivitamins should provide enough C and B6 to have a meaningful effect on breast cancer risk. And multivitamins are inexpensive and risk-free.

In addition, there are things you can do that are proven to reduce breast cancer risk. Here is what the American Cancer Society recommends:

  • Get to and stay at a healthy weight.
  • Be physically active and avoid time sitting.
  • Follow a healthy eating plan.
  • It is best not to drink alcohol.
  • Think carefully about using hormone replacement therapy.

I provide more detail about each of these recommendations in a recent article in “Health Tips From the Professor”.

The Bottom Line 

Most doctors will tell you that supplementation does not reduce your risk of breast cancer. And that opinion is backed up by multiple published clinical studies.

But the problem is that these studies are all asking the wrong question. They are asking, “Does supplementation reduce the risk of breast cancer for all women?”. A better question would be, “Which women benefit from supplementation?”

A recent study asked both of those questions. They looked at the effect of 15 micronutrients on breast cancer risk.

  1. When the investigators grouped all the women in the study together:
    • None of the 15 micronutrients influenced breast cancer risk.

2) But when the investigators separated the women by weight, an interesting dichotomy was observed:

    • For obese women (BMI ≥ 25 kg/m2):
      • Vitamin C intake above the recommended intake reduced the risk of breast cancer by 46%.
      • Vitamin B6 intake above the recommended intake reduced the risk of breast cancer by 52%.
    • For women of normal weight (BMI < 25 kg/m2) neither vitamin C nor vitamin B6 had any effect on breast cancer risk.

The authors concluded, “In obese women, exceeding the recommended daily intake levels of vitamin C and vitamin B6 was associated with a lower risk of breast cancer. However, other micronutrients were not associated with breast cancer risk in these women.”

Should Cancer Patients Take Supplements?

Does Supplementation Interfere With Cancer Treatment?

Author: Dr. Stephen Chaney

SupplementationSupplementation for cancer patients is a controversial topic.

  • Dr. Strangelove and his friends promote a variety of herbal ingredients, vitamins, and minerals as a cure for various kinds of cancer.
  • Unscrupulous supplement companies hype their cancer “cures”.
  • Doctors often tell their patients to avoid all supplements while they are being treated for cancer.
  • Nutrition experts and some doctors tell us that a good diet and basic supplementation help normal cells recover from cancer treatment and improve patient outcomes.

Where is the truth? For this article I will break it down into three questions:

1) Does supplementation improve outcomes for cancer patients? That is the topic of the study (AL Shaver et al, Cancers, 13: 6276, 2021) I will review today.

2) Does supplementation interfere with cancer treatment? I will provide a perspective and practical advice on this question based on my 40 years of cancer research.

3) Does supplementation prevent (reduce the risk of) cancer? I have covered this topic in previous issues of “Health Tips From the Professor”. Just put cancer or breast cancer in the search box to find the relevant articles.

But before I answer these questions, I should cover my favorite topic as a Biochemist, “Metabolism 101”. Specifically, “Does Stress Increase Our Need For Supplementation?”

Metabolism 101: Does Stress Increase Our Need For Supplementation? 

professor owlLet me start out by saying that there are two kinds of stress.

  • Psychological stress is our body’s response to a hectic day or a stressful work environment.
  • Metabolic stress is our body’s response to trauma or a major disease.

Dr. Strangelove and his buddies will tell you that psychological stress increases your nutritional needs. And they just happen to have the perfect blend of vitamins and minerals for you. However, this is a myth.

Psychological stress has relatively little effect on your nutritional needs. If you have a nutritional deficiency, supplementation can help you cope with psychological stress, but psychological stress doesn’t create nutritional deficiencies.

Metabolic stress, on the other hand, has a major effect on your nutritional needs.

  • Trauma and major diseases put you in a catabolic state. Catabolism literally means “breaking down”. You are breaking down your body tissues at an alarming rate. This affects every aspect of your health, including your immune system.
  • Trauma and major disease also increase your need for certain micronutrients. Plus, there are often loss of appetite and mobility issues that prevent you from getting the nutrients you need.
  • Research in the 60s and 70s showed that providing hospitalized patients with protein, energy in the form of healthy fats and carbohydrates, and micronutrients significantly shortened hospital stays and improved outcomes. Today, nutritional support is the standard of care for severely ill hospital patients.

Cancer is the poster child for metabolic stress.

  • It forces the body into a catabolic state to provide nutrients the cancer needs to grow.
    • That is why cancer patients often experience dramatic weight loss and weakness from muscle loss.
    • Catabolism also weakens the immune system, which is one of the most important tools in our fight against cancer.
  • To make matters worse:
    • Cancer treatment destroys normal cells as well as tumor cells. Because of this cancer patients sometimes die from the treatment, not the cancer.
    • Cancer treatment often causes nausea and/or suppresses appetite, which makes it even harder for cancer patients to get the nutrients they need from their diet.

Because of this, you would think that nutritional support would be the standard of care for cancer patients, but it isn’t. Because of fears that nutritional support might “feed cancer cells” or interfere with chemotherapy, there have been very few studies of supplementation in cancer patients. That is what makes this study so important.

How Was This Study Done?

Clinical StudyThis study took advantage of the fact that supplementation is prevalent among cancer patients even though their doctors may not have recommended it.

This study drew on data from the 2011-2012 National Health and Nutritional Examination Survey (NHANES). NHANES is a yearly survey that monitors the health and nutritional status of non-institutionalized adults in the US population.

NHANES participants were asked to respond to a medical condition questionnaire in their homes by a trained interviewer. In one portion of the interview, they were asked if they had ever been told they had cancer, arthritis, diabetes, congestive heart failure, chronic obstructive pulmonary disease (COPD), or hypertension. The participants were also asked if they had been hospitalized with one of those diseases.

The study consisted of 14 million people who answered ‘yes’ to the question, “Have you ever been told you had a cancer or malignancy?” The participants were selected to give an equal number of supplement users and non-users who were closely matched for age, sex, race, and other demographics.

All NHANES participants were asked to fill in two 24-hour dietary recalls separated by 3-10 days. The dietary recalls included supplement use but did not identify the kind of supplements used.

Finally, participants in the NHANES survey were asked to rate their physical and mental health on a scale from 1 (excellent health) to 5 (poor health). Participants were also asked to indicate on how many days in the past 30 days their physical or mental health was not good. A quality-of-life score was calculated from these data.

Does Supplementation Improve Outcomes For Cancer Patients?

good newsThe study found that for cancer patients:

  • Hospitalization rates were 12% for supplement users versus 21% for non-users.
  • This is important because:
    • Cancer patients who have been hospitalized have 6-fold higher odds of all-cause mortality than those who do not require hospitalization.
    • Health care costs the first year after cancer diagnosis average $60,000 versus an estimated $350-$3,500 yearly cost of supplementation.
  • The self-reported quality of life score was significantly higher for supplement users versus non-users.

This study strongly supports the idea that supplementation significantly improves quality of life and health outcomes in cancer patients.

  • This finding is consistent with previous studies showing that nutrition support significantly improves health outcomes for hospitalized patients admitted with trauma or other major diseases.
    • A major strength of the study is the large sample size (> 14 million US adults).
    • A major limitation of this study is that the NHANES survey does not record which supplements people were using.

The authors concluded, “Adequate nutrition provides a cost-effective strategy to achieving potentially optimal health [for cancer patients]. Further studies are needed to determine the effects of specific nutrient doses and supplementation on long-term outcomes for different kinds of cancer…Given the overall cost-effectiveness of dietary supplementation, there is a need for better provider education about how to talk with cancer survivors about their nutrient status and filling nutrient gaps through both food and supplements. Immune-supportive supplementation may prove to be a clinically effective and important tool that is accessible via telemedicine.”

Does Supplementation Interfere With Cancer Treatment?

Question MarkThe reason that supplementation is not more widely recommended for cancer patients is two-fold.

1) There is a fear among many doctors that improved nutrition will feed the cancer cells and promote tumor growth.

    • This thinking is like the famous quote from a general during the Vietnamese war that, “It was necessary to destroy the village in order to save it [from the Viet Cong]”.
    • We need healthy normal cells to fight the cancer and for good quality of life while we are fighting the cancer. We need to protect these cells while we are destroying the cancer cells. We cannot afford to destroy the whole “village”.
    • For example, both cancer treatment and the catabolism associated with the cancer weaken the immune system, and a strong immune system is essential to successfully fight the cancer.

2) There is also a fear that supplementation will interfere with cancer treatment. This is a more legitimate fear and deserves a more in-depth analysis.

    • There are some instances where supplementation can clearly interfere with treatment. For example,
      • Radiation treatment relies on the production of free radicals. High-dose antioxidants have been shown to interfere with radiation treatment.
      • Some drugs act by suppressing folate levels in cells. High-dose B complex or folic acid supplements would clearly interfere with these drugs. However, high-dose folic acid supplementation is often used before and after drug treatment to “rescue” normal cells.
    • There are other cases where supplementation is likely to interfere with treatment.
      • A few drugs depend in part on free radical formation. High-dose antioxidants have the potential to interfere with these drugs.
      • Some herbal supplements activate enzymes involved in the metabolism of certain anti-cancer drugs. While these interactions are rare, they could interfere with the effectiveness of these drugs. [Note: This concern only applies to certain herbal supplements. It does not apply to vitamin-mineral supplements.]
    • Most other fears about supplement-drug interactions are theoretical. There are neither potential mechanisms nor evidence to support those fears.

However, there is a strategy for minimizing the potential for supplement-drug interactions based on the science of pharmacokinetics. Simply put:

  • Most cases of supplement-drug interactions can be avoided by assuring that high doses of anti-cancer drugs and nutrients that might interfere with those drugs are not present in the bloodstream at the same time.
  • Pharmocokinetic studies tell us that most anticancer drugs and nutrients are cleared from the bloodstream in 24-48 hours.
  • So, my standard recommendation is to avoid supplementation for a day or two prior to cancer treatment and wait to resume supplementation for a day or two after cancer treatment. This recommendation does not apply to radiation treatment since it is done on a daily basis.

However, there are a few drugs that are cleared from the bloodstream more slowly, so it is always best to check with your pharmacist or doctor before deciding on the appropriate window to avoid supplementation. The goal is always to protect normal cells without interfering with the drug’s ability to kill cancer cells.

Should Cancer Patients Take Supplements?

SupplementationWith the information I have shared above in mind, I am now ready to answer the question I posed at the beginning of this article, “Should cancer patients take supplements?” The answer is a qualified, “Yes”.

Let me start with the yes, and then talk about the qualifications.

  • This study makes clear that cancer is like every other major disease that can land you in the hospital. Nutritional support, including protein supplements, vitamins, and minerals, can reduce your risk of hospitalization, get you out of the hospital quicker, and improve your quality of life.
  • A strong immune system is important for fighting cancer, so immune-supporting supplements may also be important for cancer patients.
  • Note I did not say that supplementation can cure cancer. There is little evidence to support that claim.
  • The role of supplementation in preventing cancer is complex. I have covered this in previous issues of “Health Tips From the Professor”. Let me summarize by saying that supplementation can play a role in preventing cancer when nutrient levels are suboptimal. However, the evidence that megadoses of nutrients can prevent cancer is scant.

The qualifications mostly revolve around taking supplements while undergoing cancer treatment. To summarize what I said above:

  • There are a few cases in which supplements clearly interfere with cancer treatment.
  • There are other cases in which supplements are likely to interfere with cancer treatment.
  • However, in most cases supplement-treatment interactions are only theoretical.
  • In most cases any interaction between supplements and anti-cancer drugs can be minimized by avoiding supplementation for a day or two prior to cancer treatment and waiting to resume supplementation for a day or two after cancer treatment.
  • However, there are exceptions to this rule, so it is always best to consult your pharmacist or doctor if in doubt.

The Bottom Line

A recent study looked at the effect of supplementation for patients with cancer. The study found that for cancer patients:

  • Hospitalization rates were 12% for supplement users versus 21% for non-users.
  • This is important because:
    • Cancer patients who have been hospitalized have 6-fold higher odds of all-cause mortality than those who do not require hospitalization.
    • Health care costs the first year after cancer diagnosis average $60,000 versus an estimated $350-$3,500 yearly cost of supplementation.
  • The self-reported quality of life was significantly higher for supplement users versus non-users.

This study strongly supports the idea that supplementation significantly improves quality of life and health outcomes in cancer patients.

  • This finding is consistent with previous studies showing that nutrition support significantly improves health outcomes for hospitalized patients admitted with trauma or other major diseases.

The authors concluded, “Adequate nutrition provides a cost-effective strategy to achieving potentially optimal health [for cancer patients].

Immune-supportive supplementation may prove to be a clinically effective and important tool that is accessible via telemedicine.”

Who Benefits Most From Supplementation?

Supplements Are Part of a Holistic Lifestyle

Author: Dr. Stephen Chaney

need for supplementsThe headlines about supplementation are so confusing. Are they useful, or are they a waste of money? Will they cure you, or will they kill you? I feel your pain.

I have covered these questions in depth in my book, “Slaying The Supplement Myths”, but let me give you a quick overview today. I call it: “Who Benefits Most From Supplementation?” I created the graphic on the left to illustrate why I feel responsible supplementation is an important part of a holistic lifestyle for most Americans. Let me give you specific examples for each of these categories.

 

Examples of Poor Diet

No Fast FoodYou have heard the saying that supplementation fills in the nutritional gaps in our diets, so what are the nutritional gaps? According to the USDA’s 2020-2025 Dietary Guidelines for Americans, many Americans are consuming too much fast and convenience foods. Consequently, we are getting inadequate amounts of calcium, magnesium, and vitamins A, D, E and C. Iron is considered a nutrient of concern for young children and pregnant women. In addition, folic acid, vitamin B6, and iodine are nutrients of concern for adolescent girls and pregnant women.

According to a recent study, regular use of a multivitamin is sufficient to eliminate all these deficiencies except for calcium, magnesium and vitamin D (J.B. Blumberg et al, Nutrients, 9(8): doi: 10.3390/nu9080849, 2017). A well-designed calcium, magnesium and vitamin D supplement may be needed to eliminate those deficiencies.

In addition, intake of omega-3 fatty acids from foods appears to be inadequate in this country. Recent studies have found that American’s blood levels of omega-3s are among the lowest in the world and only half of the recommended level for reducing the risk of heart disease (K.D. Stark et al, Progress In Lipid Research, 63: 132-152, 2016; S.V. Thuppal et al, Nutrients, 9, 930, 2017; M Thompson et al, Nutrients, 11: 177, 2019). Therefore, omega-3 supplementation is often a good idea.

In previous editions of “Health Tips From the Professor” I have talked about our “mighty microbiome”, the bacteria and other microorganisms in our intestine. These intestinal bacteria can affect our tendency to gain weight, our immune system, inflammatory diseases, chronic diseases such as diabetes, cancer, and heart diseases, our mood—the list goes on and on. This is an emerging science. We are learning more every day, but for now it appears our best chances for creating a health-enhancing microbiome are to consume a primarily plant-based diet and take a probiotic supplement.

Finally, diets that eliminate whole food groups create nutritional deficiencies. For example, vegan diets increase the risk of deficiencies in vitamin B12, vitamin D, calcium, iron, zinc and long chain omega-3 fatty acids. A recent study reported that the Paleo diet increased the risk of calcium, magnesium, iodine, thiamin, riboflavin, folate and vitamin D deficiency (A. Genomi et al, Nutrients, 8, 314, 2016). The Keto diet is even more restrictive and is likely to create additional deficiencies.

Examples of Increased Need

pregnant women taking omega-3We have known for years that pregnancy and lactation increase nutritional requirements. In addition, seniors have increased needs for protein, calcium, vitamin D and vitamin B12. In previous issues of “Health Tips From the Professor” I have also shared recent studies showing that protein requirements are increased with exercise.

Common medications also increase our need for specific nutrients. For example, seizure medications can increase your need for vitamin D and calcium. Drugs to treat diabetes and acid reflux can increase your need for vitamin B12. Other drugs increase your need for vitamin B6, folic acid, and vitamin K. Excess alcohol consumption increases your need for thiamin, folic acid, and vitamin B6. These are just a few examples.

Vitamin D is a special case. Many people with apparently adequate intake of vitamin D have low blood levels of 25-hydroxy vitamin D. It is a good idea to have your blood 25-hydroxy vitamin D levels measured on an annual basis and supplement with vitamin D if they are low.

More worrisome is the fact that we live in an increasing polluted world and some of these pollutants may increase our needs for certain nutrients. For example, in a recent edition of “Health Tips From the Professor” I shared a study reporting that exposure to pesticides during pregnancy increases the risk of giving birth to children who will develop autism, and that supplementation with folic acid during pregnancy reduces the effect of pesticides on autism risk. I do wish to acknowledge that this is a developing area of research. This and similar studies require confirmation. It is, however, a reminder that there may be factors beyond our control that have the potential to increase our nutritional needs.

Examples of Genetics Influencing Nutritional Needs

nutrigenomicsThe effect of genetic variation on nutritional needs is known as nutrigenomics. One of the best-known examples of nutrigenomics is genetic variation in the methylenetetrahydrofolate reductase (MTHFR) gene.  MTHFR gene mutations increase the risk of certain birth defects, such as neural tube defects. MTHFR mutations also slightly increase the requirement for folic acid. A combination of food fortification and supplementation with folic acid have substantially decreased the prevalence of neural tube defects in the US population. This is one of the great success stories of nutrigenomics. Parenthetically, there is no evidence that methylfolate is needed to decrease the risk of neural tube defects in women with MTHFR mutations.

Let me give you a couple of additional examples:

One of them has to do with vitamin E and heart disease (A.P. Levy et al, Diabetes Care, 27: 2767, 2004). Like a lot of other studies there was no significant effect of vitamin E on cardiovascular risk in the general population. But there is a genetic variation in the haptoglobin gene that influences cardiovascular risk. The haptoglobin 2-2 genotype increases oxidative damage to the arterial wall, which significantly increases the risk of cardiovascular disease. When the authors of this study looked at the effect of vitamin E in people with this genotype, they found that it significantly decreased heart attacks and cardiovascular deaths.

This has been confirmed by a second study specifically designed to look at vitamin E supplementation in that population group (F. Micheletta et al, Arteriosclerosis, Thrombosis and Vascular Biology, 24: 136, 2008). This is an example of a high-risk group benefiting from supplementation, but in this case the high risk is based on genetic variation.

Let’s look at soy and heart disease as a final example. There was a study called the ISOHEART study (W.L. Hall et al, American Journal of Clinical Nutrition, 82: 1260-1268, 2005 (http://ajcn.nutrition.org/content/82/6/1260.abstract); W.L. Hall et al, American Journal of Clinical Nutrition, 83: 592-600, 2006) that looked at a genetic variation in the estrogen receptor which increases inflammation and decreases levels of HDL. As you might expect, this genotype significantly increases cardiovascular risk.

Soy isoflavones significantly decrease inflammation and increase HDL levels in this population group. But they have no effect on inflammation or HDL levels in people with other genotypes affecting the estrogen reception. So, it turns out that soy has beneficial effects, but only in the population that’s at greatest risk of cardiovascular disease, and that increased risk is based on genetic variation.

These examples are just the “tip of the iceberg”. Nutrigenomics is an emerging science. New examples of genetic variations that affect the need for specific nutrients are being reported on a regular basis. We are not ready to start genotyping people yet. We don’t yet know enough to design a simple genetic test to predict our unique nutritional needs. That science is 10-20 years in the future, but this is something that’s coming down the road.

What the current studies tell us is that some people are high-risk because of their genetic makeup, and these are people for whom supplementation is going to make a significant difference. However, because genetic testing is not yet routine, most people are completely unaware that they might be at increased risk of disease or have increased nutritional requirements because of their genetic makeup.

Examples of Disease Influencing Nutritional Needs

Finally, let’s consider the effect of disease on our nutritional needs. If you look at the popular literature, much has been written about the effect of stress on our nutritional needs. In most case, the authors are referring to psychological stress. In fact, psychological stress has relatively minor effect on our nutritional needs.

Metabolic stress, on the other hand, has major effects on our nutritional needs. Metabolic stress occurs when our body is struggling to overcome disease, recover from surgery, or recover from trauma. When your body is under metabolic stress, it is important to make sure your nutritional status is optimal.

The effects of surgery and trauma on nutritional needs are well documented. In my book, “Slaying The Supplement Myths”, I discussed the effects of disease on nutritional needs in some detail. Let me give you a brief overview here. It is very difficult to show beneficial effects of supplementation in a healthy population (primary prevention). However, when you look at populations that already have a disease, or are at high risk for disease, (secondary prevention), the benefits of supplementation are often evident.

For example, studies suggest that vitamin E, B vitamins, and omega-3s each may reduce heart disease risk, but only in high-risk populations. Similarly, B vitamins (folic acid, B6 and B12) appear to reduce breast cancer risk in high risk populations.

Who Benefits Most From Supplementation?

Question MarkWith this information in mind, let’s return to the question: “Who benefits most from supplementation? Here is my perspective.

1) The need for supplementation is greatest when these circles overlap, as they do for most Americans.

2) The problem is that while most of us are aware that our diets are not what they should be, we are unaware of our increased needs and/or genetic predisposition. We are also often unaware that we are at high risk of disease. For too many Americans the first indication they have heart disease is sudden death, the first indication of high blood pressure is a stroke, or the first indication of cancer is a diagnosis of stage 3 or 4 cancer.

So, let’s step back and view the whole picture. The overlapping circles are drawn that way to make a point. A poor diet doesn’t necessarily mean you have to supplement. However, when a poor diet overlaps with increased need, genetic predisposition, disease, or metabolic stress, supplementation is likely to be beneficial. The more overlapping circles you have, the greater the likely benefit you will derive from supplementation.

That is why I feel supplementation should be included along with diet, exercise, and weight control as part of a holistic approach to better health.

The Bottom Line

In this article I provide a perspective on who benefits most from supplementation and why. There are four reasons to supplement.

  1. Fill Nutritional gaps in our diet

2) Meet increased nutritional needs due to pregnancy, lactation, age, exercise, many common medications, and environmental pollutants.

3) Compensate for genetic variations that affect nutritional needs.

4) Overcome needs imposed by metabolic stress due to trauma, surgery, or disease.

With this information in mind, let’s return to the question: “Who benefits most from supplementation? Here is my perspective.

  1. A poor diet alone doesn’t necessarily mean you have to supplement. However, when a poor diet overlaps with increased need, genetic predisposition, or metabolic stress, supplementation is likely to be beneficial. The more overlap you have, the greater the likely benefit you will derive from supplementation.

2) The problem is that while most of us are aware that our diets are not what they should be, we are unaware of our increased needs and/or genetic predisposition. We are also often unaware that we are at high risk of disease. For too many Americans the first indication they have heart disease is sudden death, the first indication of high blood pressure is a stroke, or the first indication of cancer is a diagnosis of stage 3 or 4 cancer.
