What The Food And Supplement Industries Don’t Want You To Know

Author: Dr. Stephen Chaney

 

deceptive food labelsHealthy Eating Is In. We are told we need more fiber, whole grains, fruits & vegetables, nuts and omega-3s in our diet. We are being told that we should be eating “super foods” we’ve never heard of because of their amazing health benefits. As a consequence, more and more Americans are reading labels to be sure that the foods and supplements they are buying are healthy.  We trust the FDA and others not to allow us to be had by deceptive food labels.

But what if those food labels were deceptive? What if the food labels were more about marketing than about real health benefits? Is it possible that BIG FOOD Inc. and the supplement industry could actually be lying to us? Could it be that the manufacturers care more about their profits than about our health?

Deceptive Food Labels? 

Vegetable & Fruit Follies In The Supermarket

Everyone knows that fruits and vegetables are good for us. They are chock-full of vitamins, minerals, and phytonutrients as well as fiber. But who wants to spend the time peeling an orange or washing the pesticides off that broccoli? It’s much more fun to get our fruits and vegetables from chips, pasta, and breakfast cereals.

companies that use deceptive food labelsFood manufacturers are only too happy to oblige. The chemical companies make a variety of fruit and vegetable powders that food manufacturers can add to their products. For example, Powder Pure tells food manufacturers “Whether you want to add nutrition to your label, infuse full color, or formulate a specific flavor profile for your discerning consumers, Powder Pure has the right powder to enhance your presence in the marketplace.”  You will notice they are talking about adding nutrition to the label, not to the food. They are talking about “enhancing your presence in the marketplace,” not making your food healthier.

The problem is that sprinkling a little fruit and vegetable powder into a processed food will never provide the full range of nutrients that those fruits and vegetables would have provided.

Most manufacturers can’t (or won’t) specify the amounts of nutrients and phytonutrients you get from the fruit & vegetable powders they add to their processed foods, but that doesn’t stop them from making label claims like “We pop a flavorful blend of nine veggies…[in our chips]” or there is “half serving of vegetables in a 2 oz serving…[of our pasta].”  Is this using deceptive food labels?

The Fruits & Vegetables in a Capsule Con

One of my pet peeves is the food supplement manufacturers who try to tell you that they have concentrated a cornucopia of fresh fruits and vegetables in a capsule. For example, one company claims that their capsules contain apple, barley, broccoli, beet, cabbage, carrot, cranberry, date, garlic, kale, oats, orange, parsley, peach, pineapple, prunes, spinach, plant enzymes, fiber, and acidophilus.  All this in one capsule!  Does that sound like the use of deceptive food labels?

While this list sounds impressive, you need to ask whether they are providing meaningful amounts of those fruits and vegetables.  For example, the product claims to have oats.  A serving of oats is equal to 1/3 cup dry oats and weighs about 28 grams.  A capsule typically weighs about 0. 5 grams. Therefore, to get the equivalent of one serving of oats from a capsule, you would have to consume 56 capsules!  And that’s assuming that the entire capsule was filled with oats.

Broccoli is another claimed ingredient.  A serving of fresh broccoli weighs 88 grams, but roughly 80 grams of that is water.  So if you dehydrated the broccoli you would be left with about 8 grams of material. Therefore, to get a single serving of dehydrated broccoli you would have to consume 16 capsules. Again, that’s assuming that the capsules were completely filled with just broccoli.

You can do this kind of calculation with each ingredient they claim is in their capsules.  But when you add up the number of capsules needed to get a reasonable amount of each of these ingredients, the capsule total is staggering.

deceptive food labels marketingAs for essential nutrients, when you read the labels on some of these products you discover that their capsules only contain small amounts of a few essential nutrients. They simply do not provide significant amounts of the vitamins, minerals, and phytonutrients you would have been getting if you ate the real foods.

On the other hand, if the label does list significant amounts of the essential nutrients, that’s usually because purified vitamins and minerals have been added to the final product. Those products are no different from any other multivitamin supplement except that they contain insignificant quantities of fruit and vegetable powders that provide no additional health benefits. Once again, it’s all about using deceptive food labels marketing, not your good health.

Faux Protein Supplements

The same deceptive marketing practices have also entered the lucrative protein supplement marketplace. You are being told about protein products that are full of fruits & vegetables, super foods and herbs. It all sounds wonderful, but once again it is all smoke and mirrors. These companies are just mixing a little fruit and vegetable powders in with their protein powder.

You are being told that these products contain dozens of fruits and vegetables that provide vitamins and antioxidants in their natural form. However, when you read the label it is obvious that many of the vitamins and minerals in that product never saw a fruit or vegetable. They were synthesized in a chemical laboratory and added to the final product along with the fruit and vegetable powders.

You are being told that these products contain super foods that provide important phytonutrients, but none of those phytonutrients is present in sufficient quantities to be featured on the nutrition label. You are told that these products contain herbal ingredients with amazing healing powers, but none of the active ingredients of the claimed herbs are present in high enough quantities to be included on the nutrition label.

fruits and vegetablesOnce again, it is all about marketing. Manufacturers are adding fruit and vegetable powders and a pinch of herbal ingredients to their protein powders so that they can make marketing claims, but those fruit and vegetable powders and herbal ingredients aren’t present in large enough quantities to make any significant impact on your health.

Allowed Label Claims

Many of you have asked me about companies that claim their supplement has the amount of vitamin C found in 7 oranges or the amount of folic acid found in 4 cups of cooked green peas.  Those are allowed claims and are generally accurate. Just don’t assume that the vitamin C actually came from 7 oranges (it didn’t) or that their supplement has all the nutrients found in 7 oranges (it doesn’t).  Again, these companies find ways to use deceptive food labels to make sales.

 

The Bottom Line

  • We are being told that we should read labels to make sure that the foods and supplements we buy are good for us. We are also being told that we should be eating more fruits and vegetables. Food manufacturers know an emerging trend when they see one, so many of them are adding fruit and vegetable powders to the foods and supplements they manufacture. This increases the marketing appeal of their products, but does nothing to make their products healthier. It is label deception, pure and simple.

If you want to avoid being deceived by deceptive food labels, you should:

  • Ignore the label claims of fruits and vegetables added to the processed foods you see in the market. The fruit and vegetable powders added to those foods provide no proven benefit. The best place to get your fruits and vegetables is to [surprise] eat your fruits and vegetables.
  • Leave those supplements claiming to have concentrated lots of fruits and vegetables into a single capsule on the shelf. Those claims are grossly deceptive because the capsules do not contain significant amounts of the fruits and vegetables listed on the label. They do not provide the nutrients you would have gotten if you had eaten the real foods. Once again, the best way to get the fruits and vegetables you need in your diet is to actually eat fresh fruits and vegetables.
  • Forget those protein supplements that make amazing claims based on all the fruits, vegetables, super foods, and herbal ingredients they have. Once again, the fruit and vegetable powders and herbal ingredients in these products are not present in sufficient quantities to provide any significant health benefits. It is the marketing that is amazing, not the health benefits.
  • Finally, many of you have asked me about companies that claim their supplement has the amount of vitamin C found in 7 oranges or the amount of folic acid found in 4 cups of cooked green peas. Those are allowed claims and are generally accurate. Just don’t assume that the vitamin C actually came from 7 oranges (it didn’t) or that their supplement has all the nutrients found in 7 oranges (it doesn’t).

Does Magnesium Optimize Vitamin D Levels?

The Case For Holistic Supplementation

Author: Dr. Stephen Chaney

 

Does magnesium optimize vitamin D levels?

magnesium optimize vitamin dOne of the great mysteries about vitamin D is the lack of correlation between vitamin D intake and blood levels of its active metabolite, 25-hydroxyvitamin D. Many people who consume RDA levels of vitamin D from foods and/or supplements end up with low blood levels of 25-hydroxyvitamin D. The reason(s) for this discrepancy between intake of vitamin D and blood levels of its active metabolite are not currently understood.

Another great mystery is why it has been so difficult to demonstrate benefits of vitamin D supplementation. Association studies show a strong correlation between optimal 25-hydroxyvitamin D levels and reduced risk of heart disease, cancer, and other diseases. However, placebo-controlled clinical trials of vitamin D supplementation have often come up empty. Until recently, many of those studies did not measure 25-hydroxyvitamin D levels. Could it be that optimal levels of 25-hydroxyvitamin D were not achieved?

The authors of the current study hypothesized that optimal magnesium status might be required for vitamin D conversion to its active form. You are probably wondering why magnesium would influence vitamin D metabolism. I had the same question.

The authors pointed out that:

  • Magnesium status affects the activities of enzymes involved in both the synthesis and degradation of 25-hydroxyvitamin D.
  • Some clinical studies have suggested that magnesium intake interacts with vitamin D intake in affecting health outcomes.
  • If the author’s hypothesis is correct, it is a concern because magnesium deficiency is prevalent in this country. In their “Fact Sheet For Health Professionals,” the NIH states that “…a majority of Americans of all ages ingest less magnesium from food than their respective EARs [Estimated Average Requirement]; adult men aged 71 years and older and adolescent females are most likely to have low intakes.” Other sources have indicated that magnesium deficiency may approach 70-80% for adults over 70.

If the author’s hypothesis that magnesium is required for vitamin D activation is correct and most Americans are deficient in magnesium, this raises some troubling questions.

  • Most vitamin D supplements do not contain magnesium. If people aren’t getting supplemental magnesium from another source, they may not be optimally utilizing the vitamin D in the supplements.
  • Most clinical studies involving vitamin D do not also include magnesium. If most of the study participants are deficient in magnesium, it might explain why it has been so difficult to show benefits from vitamin D supplementation.

Thus the authors devised a study (Q Dai et al, American Journal of Clinical Nutrition, 108: 1249-1258, 2018 ) to directly test their hypothesis.

 

How Was The Study Designed?

magnesium optimize vitamin d studyThe authors recruited 180 volunteers, aged 40-85, from an ongoing study on the prevention of colon cancer being conducted at Vanderbilt University. The duration of the study was 12 weeks. Blood was drawn at the beginning of the study to measure baseline 25-hydroxyvitamin D levels. Three additional blood draws to determine 25-hydroxyvitamin D levels were performed at weeks 1, 6, and 12.

Because high blood calcium levels increase excretion of magnesium, the authors individualized magnesium intake based on “optimizing” the calcium to magnesium ratio in the diet rather than giving everyone the same amount of magnesium. The dietary calcium to magnesium ratio for most Americans is 2.6 to 1 or higher. Based on their previous work, they considered an “ideal” calcium to magnesium ratio to be 2.3 to 1. The mean daily dose of magnesium supplementation in this study was 205 mg, with a range from 77 to 390 mg to achieve the “ideal” calcium to magnesium ratio. The placebo was an identical gel capsule containing microcrystalline cellulose.

Two 24-hour dietary recalls were conducted at baseline to determine baseline dietary intake of calcium and magnesium. Four additional 24-hour dietary recalls were performed during the 12-week study to assure that calcium intake was unchanged and the calcium to magnesium ratio of 2.3 to 1 was achieved.

In short this was a small study, but it was very well designed to test the author’s hypothesis.

 

Does Magnesium Optimize Vitamin D Levels?

 

does magnesium optimize vitamin d levelsThis was a very complex study, so I am simplifying it for this discussion. For full details, I refer you to the journal article (Q Dai et al, American Journal of Clinical Nutrition, 108: 1249-1258, 2018).

The most significant finding was that magnesium supplementation did affect blood levels of 25-hydroxyvitamin D. However, the effect of magnesium supplementation varied depending on the baseline 25-hydroxyvitamin D level at the beginning of the study.

  • When the baseline 25-hydroxyvitamin D was 20 ng/ml or less (which the NIH considers inadequate), magnesium supplementation had no effect on 25-hydroxyvitamin D levels.
  • When the baseline 25-hydroxyvitamin D was 20-30 ng/ml (which the NIH considers the lower end of the adequate range), magnesium supplementation increased 25-hydroxyvitamin D levels.
  • When the baseline 25-hydroxyvitamin D level approached 50 ng/ml (which the NIH says may be “associated with adverse effects”), magnesium supplementation lowered 25-hydroxyvitamin D levels.

The simplest interpretation of these results is:

  • When vitamin D intake is inadequate, magnesium cannot magically create 25-hydroxyvitamin D from thin air.
  • When vitamin D intake is adequate, magnesium can enhance the conversion of vitamin D to 25-hydroxyvitamin D.
  • When vitamin D intake is too high, magnesium can help protect you by lowering 25-hydroxyvitamin D levels.

The authors concluded: “Our findings suggest that optimal magnesium status may be important for optimizing 25-hydroxyvitamin D status. Further dosing studies are warranted…”

 

What Does This Study Mean For You?

magnesium optimize vitamin d for youThis was a groundbreaking study that has provided novel and interesting results.

  • It provides the first evidence that optimal magnesium status may be required for optimizing the conversion of vitamin D to 25-hydroxyvitamin D.
  • It suggests that optimal magnesium status can help normalize 25-hydroxyvitamin D levels by increasing low levels and decreasing high levels.

However, this was a small study and, like any groundbreaking study, has significant limitations. For a complete discussion of the limitations and strengths of this study I refer you to the editorial (S Lin and Q Liu, American Journal of Clinical Nutrition, 108: 1159-1161, 2018) that accompanied the study.

In summary, this study needs to be replicated by larger clinical studies with a more diverse study population. In order to provide meaningful results, those studies would need to carefully control and monitor calcium, magnesium, and vitamin D intake. There is also a need for mechanistic studies to better understand how magnesium can both increase low 25-hydroxyvitamin D levels and decrease high 25-hydroxyvitamin D levels.

However, assuming the conclusions of this study to be true, it has some interesting implications:

  • If you are taking a vitamin D supplement, you should probably make sure that you are also getting the DV (400 mg) of magnesium from diet plus supplementation.
  • If you are taking a calcium supplement, you should check that it also provides a significant amount of magnesium. If not, change supplements or make sure that you get the DV for magnesium elsewhere.
  • I am suggesting that you shoot for the DV (400 mg) of magnesium rather than reading every label and calculating the calcium to magnesium ratio. The “ideal” ratio of 2.3 to 1 is hypothetical at this point. A supplement providing the DV of both calcium and magnesium would have a calcium to magnesium ratio of 2.5, and I would not fault any manufacturer for providing you with the DV of both nutrients.
  • If you are taking high amounts of calcium, I would recommend a supplement that has a calcium to magnesium ratio of 2.5 or less.
  • If you are considering a magnesium supplement to optimize your magnesium status, you should be aware that magnesium can cause gas, bloating, and diarrhea. I would recommend a sustained release magnesium supplement.
  • Finally, whole grains and legumes are among your best dietary sources of magnesium. Forget those diets that tell you to eliminate whole food groups. They are likely to leave you magnesium-deficient.

Even if the conclusions of this study are not confirmed by subsequent studies, we need to remember that magnesium is an essential nutrient with many health benefits and that most Americans do not get enough magnesium in their diet. The recommendations I have made for optimizing magnesium status are common-sense recommendations that apply to all of us.

 

The Case For Holistic Supplementation

 

magnesium optimize vitamin d case for holistic supplementationThis study is one of many examples showing that a holistic approach to supplementation is superior to a “magic bullet” approach where you take individual nutrients to solve individual problems. For example, in the case of magnesium and vitamin D:

  • If you asked most nutrition experts and supplement manufacturers whether it is important to provide magnesium along with vitamin D, their answer would likely be “No”. Even if they are focused on bone health, they would be more likely to recommend calcium along with vitamin D than magnesium along with vitamin D.
  • If your doctor has tested your 25-hydroxyvitamin D levels and recommended a vitamin D supplement, chances are they didn’t also recommend that you optimize your magnesium status.
  • Clinical studies investigating the benefits of vitamin D supplementation never ask whether magnesium intake is optimal.

That’s because most doctors and nutrition experts still think of nutrients as “magic bullets.” I cover holistic supplementation in detail in my book “Slaying The Supplement Myths.”  Other examples that make a case for holistic supplementation that I cover in my book include:

  • A study showing that omega-3 fatty acids and B vitamins may work together to prevent cognitive decline. Unfortunately, most studies looking at the effect of B vitamins on cognitive decline have not considered omega-3 status and vice versa. No wonder those studies have produced inconsistent results.
  • Studies looking at the effect of calcium supplementation on loss of bone density in the elderly have often failed to include vitamin D, magnesium, and other nutrients that are needed for building healthy bone. They have also failed to include exercise, which is essential for building healthy bone. No wonder some of those studies have failed to find an effect of calcium supplementation on bone density.
  • A study reported that selenium and vitamin E by themselves might increase prostate cancer risk. Those were the headlines you might have seen. The same study showed Vitamin E and selenium together did not increase prostate cancer risk. Somehow that part of the study was never mentioned.
  • A study reported that high levels of individual B vitamins increased mortality slightly. Those were the headlines you might have seen. The same study showed that when the same B vitamins were combined in a B complex supplement, mortality decreased. Somehow that observation never made the headlines.
  • A 20-year study reported that a holistic approach to supplementation produced significantly better health outcomes.

In summary, vitamins and minerals interact with each other to produce health benefits in our bodies. Some of those interactions we know about. Others we are still learning about. When we take high doses of individual vitamins and minerals, we create potential problems.

  • We may not get the full benefit of the vitamin or mineral we are taking because some other important nutrient(s) may be missing from our diet.
  • Even worse, high doses of one vitamin or mineral may interfere with the absorption or enhance the excretion of another vitamin or mineral. That can create deficiencies.

The same principles apply to our diet. I mentioned earlier that whole grains and legumes are among the best dietary sources of magnesium. Eliminating those two foods from the diet increases our risk of becoming magnesium deficient. And, that’s just the tip of the iceberg. Any time you eliminate foods or food groups from the diet, you run the risk of creating deficiencies of nutrients, phytonutrients, specific types of fiber, and the healthy gut bacteria that use that fiber as their preferred food source.

The Bottom Line

 

A recent study suggests that optimal magnesium status may be important for optimizing 25-hydroxyvitamin D status. This is one of many examples showing that a holistic approach to supplementation is superior to a “magic bullet” approach where you take individual nutrients to solve individual problems. For example, in the case of magnesium and vitamin D:

  • If you asked most nutrition experts and supplement manufacturers whether it is important to provide magnesium along with vitamin D, their answer would likely be “No.”  Even if they are focused on bone health, they would be more likely to recommend calcium along with vitamin D than magnesium along with vitamin D.
  • If your doctor has tested your 25-hydroxyvitamin D levels and recommended a vitamin D supplement, chances are he or she did not also recommend that you optimize your magnesium status.
  • Clinical studies investigating the benefits of vitamin D supplementation never ask whether magnesium intake is optimal. That may be why so many of those studies have failed to find any benefit of vitamin D supplementation.

I cover holistic supplementation in detail in my book “Slaying The Supplement Myths” and provide several other examples where a holistic approach to supplementation is superior to taking individual supplements.

In summary, vitamins and minerals interact with each other to produce health benefits in our bodies. Some of those interactions we know about. Others we are still learning about. Whenever we take high doses of individual vitamins and minerals, we create potential problems.

  • Even worse, high doses of one vitamin or mineral may interfere with the absorption or enhance the excretion of another vitamin or mineral. That can create deficiencies.

The same principles apply to what we eat. For example, whole grains and legumes are among the best dietary sources of magnesium. Eliminating those two foods from the diet increases our risk of becoming magnesium deficient. And, that’s just the tip of the iceberg. Any time you eliminate foods or food groups from the diet, you run the risk of creating deficiencies.
