No: Should Your DNA or  Gut Microbiome Determine What You Eat or Your Nutritional Supplements?

I take this to help control blood pressure

From Scott Gavura at Science Based Medicine:

Our ability to collect DNA data is progressing quickly, and in time we may have more evidence to inform decisions about nutrition and possibly even supplements. At this time, however, there is a big gap between what we know, and what, if anything, to do with that information. You don’t need a DNA test or a stool sample to know that eating a varied, healthy diet, minimizing highly processed foods, eliminating trans fats, and keeping alcohol consumption moderate are reasonable approaches to designing your diet. It’s worth noting again, as we have blogged about many times before, that the evidence for taking supplementary vitamins, in general, is neutral to negative. In the absence of a specific medical need (e.g., pregnancy) there a few circumstances where routine supplementation is necessary or warranted. There is no robust evidence to date to show that personalized, “DNA-based” or “microbiome-based” nutritional recommendations give useful, actionable nutrition advice that actually improve health outcomes.

Hucksters use sciency terms to convince you they know the best weight-loss diet or supplements for you. Don’t believe it.
