News on Food as Medicine

As a conventional medical journal and one of the leading medical journals in the world, The Journal of the American Medical Association doesn’t often publish reviews of the impact of food on health. However, a recent edition of the Journal included a summary of three such studies, and that’s the topic for this week.

The first study examined whether mushrooms, which are full of vitamins, minerals, and phytonutrients, decrease the risk of cardiovascular disease (CVD) or type 2 diabetes (T2D). The researchers re-analyzed the data from the Nurses’ Health Study and the Health Professionals Follow-up Study. When they compared more than five servings of mushrooms per day with less than one serving per day, they found no differences in the rate of symptoms or markers associated with CVD or T2D. One interesting note was that if mushrooms were substituted for meat, there was a decreased risk of T2D.

This is one of the first studies to acknowledge the problems with nutrition data in these types of studies. The data on mushrooms were only collected at the beginning of the studies; that doesn’t allow for comparisons over time. Further, the questionnaire didn’t allow for data on a variety of types of mushrooms. The best observation at this point is that we don’t know whether mushrooms or specific types of mushrooms are beneficial for reducing the risk of disease until more research is done.

We do know they’re good for you, so enjoy your mushrooms; sautéed mushrooms are a great addition to many dishes. Here’s another way to enjoy mushrooms: Creamy Mushroom Soup from the Health Info page at drchet.com. Check out the other recipes while you’re there.

We’ll look at another study on Thursday.

2018’s Worst Most-Read Paper

In March of last year, the Journal of the American Medical Association published a viewpoint written by two experts in public health titled “Vitamin and Mineral Supplements. What Clinicians Need to Know”; it was one of the nutrition papers most read and most shared last year. The only problem is that clinicians really won’t find out much by reading it.

I’m going to pick one recommendation because everything after it won’t matter. The authors recommend that all clinicians recommend that patients get their nutrients from food. I absolutely agree with that. They go on to advise clinicians to tell their patients there’s no need to take any dietary supplements if they eat a healthy diet. That’s plain wrong.

We already know that over 90% of all adults do not get enough servings of vegetables, fruit, and whole grains every day—and it’s proven that food contains less nutrition than in the past—yet the authors did not recommend doing a nutrition analysis for the patient. With little to no information about the patient’s diet, clinicians are to tell their patients to eat a healthy diet, don’t take any supplements, and go on their way.

These are exceptional researchers; they know how poor the American diet is because they’ve done much of that research. To publish this opinion was incomplete in my opinion and thus it ranks as one of the worst papers of 2018. With almost a quarter million reads and shares passed along through social media and news feeds, millions read what they wrote, and it will influence millions. My opinion is that millions will be less healthy because they accepted these recommendations and dropped their nutrition insurance: their multivitamin and omega 3s and so on.

That doesn’t mean you take every dietary supplement that comes along. The rule is simple: know what supplements you take and more important, exactly why you’re taking them. And work on eating a healthier diet in 2019 as well.
