Who takes dietary supplements, and why?
If you’re a regular reader of this blog, I’ll bet you’re not a regular consumer of vitamins or supplements. I’m in that group. Aside from sporadic vitamin D in winter, I don’t take any vitamins or supplements routinely, nor do I give any to my children. Your reasons may be close to mine: There is little to no evidence suggesting that dietary deficiencies...
Death as a Foodborne Illness Curable by Veganism
Can you cure death through a vegan diet? Of course not. But some people claim you can.
Should you be “Eating Clean”?
Like many of you I’m interested in the science of good nutrition. In general, I’ve come to be pretty skeptical of the nutritional literature, as so many studies seem to follow the same trajectory that we see with drug studies: Trivial changes in non-relevant outcomes, a failure to consider the results in the context of the accumulated scientific evidence and often, significant...
The Shred Diet: A Minimally Kooky Way To Lose Weight
With New Years’ weight loss resolutions freshly made, let’s take a science-based look at another of the latest diet books being promoted by various public relations agencies. In my last post we explored the claims made by the hysterical Eat To Save Your Life authors in their book featuring a demonic cheeseburger on its cover jacket. Today I will review, Shred: The...
The Dr. Oz Red Palm Oil (non-) Miracle
If there is an antithesis to the principles of science-based medicine, it’s probably the Dr. Oz show. In this daytime television parallel universe, anecdotes are evidence. There are no incremental advances in knowledge — only medical miracles. And every episode neatly offers up three or four takeaway health nuggets that, more often than not, seem to leave the audience more ill-informed about...
Everything we eat causes cancer…sort of
Red meat causes cancer. No, processed meat causes cancer. OK, it’s both red meat and processed meat. Wait, genetically modified grain causes cancer (well, not really). No, aspartame causes cancer. No, this food coloring or that one causes cancer. Clearly, everything you eat causes cancer! That means you can avoid cancer by avoiding processed meats, red meat, GMO-associated food (no, probably not),...
Nutrigenomics – Not Ready for Prime Time
Quackery in medicine takes many forms – use of bad science (pseudoscience), fraud, and reliance on mysticism are a few examples. Perhaps the most insidious form of dubious practice, however, is to use genuine and promising medical science to promote treatments that are simply not at the point of clinical application. New treatments, and especially new approaches to treatment, in medicine often...
Eat To Save Your Life: Another Half-True Diet Book
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However, after being approached by the authors’ PR agency with the promise of a book that contains science-based nutrition information I decided to agree to the...
The Obesity Paradox
Being fat is bad except when it’s good. It’s called “the obesity paradox.” (No, that isn’t a mis-spelling for “two physicians who treat fat people.”) The adverse health effects of obesity are well established, but there are exceptions. Obesity appears to confer an advantage in certain subgroups with conditions like heart disease and diabetes. In the News Casual consumers of some recent...
The Sweetener Wars – HFCS Strikes Back
The health conscious and trendy public are a bit obsessed with the food they consume. This can be a good thing, to the extent that it results in a more healthful diet, but unfortunately those interested in improving their diet must wade through a great deal of misinformation before getting to accurate and helpful information. For example, I recently gave a lecture...
