Looking for Single-Nutrient Solutions

/in /by

As you might expect, I get asked a lot of questions about health, especially diet and exercise. One of the similarities between questions is whether a specific nutrient is special or unique. When I do the research to learn about the nutrient, I’ve never found one that’s the be-all and end-all—not turmeric or echinacea or omega-3 fatty acids or anything else. Can they be beneficial? Absolutely. But they’re a finishing touch, not a foundation.

The foundation of health begins with vegetables, fruits, whole grains, quality protein, and the best oils. The foundation also includes basic supplementation such as a multivitamin-multimineral and probiotics, among others. If you don’t begin with the best diet, then specific nutritional gaps, whether due to food preferences or genetic issues, can’t be bridged effectively because the body isn’t built on a strong foundation. Once you build your foundation, some of the specific nutrients can fill in gaps and act as insurance for the days you can’t eat as well as you know you should.

Eat better. Eat less. Move more. Build a foundation and you might find miracle nutrients aren’t really necessary.

Food Is Better Than Supplements, But …

/in /by

Getting your nutrients from food by eating a healthy diet is the most desirable way of getting vitamins, minerals, and phytonutrients. Period. If we could all do it, no question that’s the best way. But you and I don’t live in some fantasy world. We’re busy. We don’t always have enough time to shop and cook healthy meals. Dietary supplements have helped fill the nutrition gap.

What should we think about this latest research? Should we stop taking supplements, especially calcium? Before I give you my opinion, I want to tell you that I emailed the corresponding author of the paper, a brilliant woman and a talented researcher. I had two questions about the study. She answered me the same evening—Saturday night before Easter. That I got such quick reply was remarkable; I’m still waiting for answers from other researchers I contacted months ago.

The first question I asked was a basic one: what was the mortality rate of the subjects in the study compared with the national cancer mortality rate? The national mortality rate is 156 deaths per 100,000 people per year. That works out to 1.6 people per 1,000. The rate in the study was about 3 people per 1,000. She replied that the study results are not directly comparable for complicated reasons.

But here’s something that can be directly compared. A 62% increase in cancer mortality would be transferable to national statistics because that’s the idea: to generalize to the entire population. A 62% increase means that 2.5 people per 1,000 would die from cancer in a given year instead of 1.6. When applied to the entire population that could be a lot of people, but it applies only to those who took over 1,000 mg of calcium per day.

The other question I asked was whether they had data on how long the people were taking the supplements; NHANES asked about the 30 days prior and recorded the prior 24 hours. How long were they taking the supplements? Weeks? Months? Years? Decades? That might have made some difference. The data were collected in the questionnaires used for two of the cycles that I examined, but that data was not used in the analysis.


The Bottom Line

I think we should eat the best diet we can. I also think we should use quality dietary supplements to complement our diet. This study was an exercise in statistics more than nutrition. It can tell us the statistical outcomes of the people in the study, but it can’t really be used to tell us anything about what we should do as individuals.

Not every person who took a higher amount of calcium died from cancer. On top of that, if supplementation did have a significant negative impact on our health, it stands to reason there would have been more negative results than just for calcium. Because the research questions were fitted to the available data, there’s just too much we don’t know about factors that can influence the results.

Another good question the study didn’t ask is why people were taking calcium. For instance, a woman with osteoporosis may take calcium for better bone health. Did those women have fewer broken bones with supplementation? If so, that might be worth any higher risk that exists. As with any nutritional intervention, it’s important to weigh the pros and cons. If you’re concerned, talk to your healthcare professional about what you should do; they know you and your health status and can help you make the right choices.

Food vs. Supplements

/in /by

Last week, the health headlines blared that nutrients from foods were better than nutrients from supplements—specifically that excess calcium from supplements was associated with an increased risk of dying from cancer. That will get your attention if you take supplemental calcium, especially if you’re taking calcium because your physician told you to take it because you have osteopenia or osteoporosis. Let’s take a closer look at this study published in the Annals of Internal Medicine.

Researchers examined data collected for the National Health and Nutrition Examination Survey (NHANES) on food intake and supplement use. NHANES data are now collected every two years, so they selected six consecutive cycles and tracked the all-cause mortality from subjects in those data. They found that in over 30,000 adults over 20 years of age tracked for six years, there were 3,613 deaths with 805 from cancer.

The researchers then examined the food intake and supplement use of the subjects from the prior 30 days of data collection with mortality data. That’s where they discovered that in the subjects who died from cancer, there was a 62% greater risk if they took more than 1,000 mg of supplemental calcium per day. The overall conclusion was that nutrients from foods are better than nutrients from supplements; in addition, some supplements may be hazardous.

Should you start chucking out your calcium supplements? We’ll take a closer look at this study the rest of this week.

Supplementing Your Diet

/in /by

Last week, a study was published that concluded that nutrients from food are better than nutrients from supplements. Does that mean you can throw out the supplements and just eat more? Short answer: no.

Did you ever notice that one week some vitamin is good for you and the next it’s supposed to be bad for you? Why is that? One reason is the way nutrition research is done.

One of the most popular audios I’ve ever made was Supplements Made Simple, so now I’ve updated all the tracks and included a section about the problems with nutrition research.

Introducing Supplementing Your Diet—Why, What, and Who. This CD examines the issues related to dietary supplements in the 21st century. The first question is simply why do we need them? Can’t we get enough nutrients from the food we eat? I’ll address that question from a variety of perspectives, including those based on your physiology and biochemistry.

What about the research that says supplements aren’t necessary and are a waste of money? As I said, I’ll tackle that issue head on with three specific reasons too much research on supplements is flawed and yields misleading conclusions.

If you do need to supplement your diet, where do you begin? I’ll explain the four supplements everyone should take and the reasons why.

Finally, how do you decide which company to buy supplements from? I’ll give you five characteristics that distinguish a high-quality manufacturer. That will help you choose the company whose supplements are best for you. This audio cuts through the forest of obstacles to help you see things clearly so you can make an informed decision on how to supplement your diet.

All this information is just $9.95 plus shipping and handling.

And if you’re in the supplement business, this audio will answer your potential clients’ questions about the basics. If you want to grow your supplement business, I’ve included special pricing on five copies of this CD so you can loan them to clients to help them make their decisions. You can point them to my online bio to show them why they can rely on my explanations.

Enjoy this holiday weekend, and I’ll be back Tuesday.
