Sensitive to Gluten-Free Claims

May 21, 2014 — Research is making it clear that far more people are sensitive to gluten-free claims than are sensitive to gluten itself. Late last year, Peter Gibson published new research showing that few, if any, people have gluten sensitivity unless they have actual celiac disease.

5 Questionable Obesity Causes

May 19, 2014 — The list of potential obesity causes seems to grow like kudzu. Why? Well, obesity develops slowly and improves slowly, if at all.

May 17, 2014 — A new study of depression in obesity just published in the British Journal of Psychiatry finds that high BMI likely does not cause depression.

Beware These 3 Nutrition Dogmas

May 15, 2014 — Nutrition dogmas are surprisingly common, with beliefs and presumptions too often driving conclusions, rather than good evidence. Here are three to beware. Low Fat. Advice to adhere to a low-fat diet became almost universal in the 80s, continuing through the turn of the millennium. This strategy was enshrined in policy through nutritional guidelines, despite limited empiric […]

3 Ways More Labeling Is Not Better

May 14, 2014 — The big fuss over labeling GMO (genetically modified organism) foods is the latest chapter of an age-old conflict over how much labeling is enough. Vermont Governor Peter Shumlin signed a bill last week to require food products with GMO ingredients to have that fact called out on the label. Transparency and right-to-know concerns push some to […]
