This is being widely reported as evidence that organic meat and milk is healthier, but a closer look at these two studies shows a different picture. The organic false dichotomy I...

Prenatal Multivitamins and Iron: Not Evidence-Based

When I was pregnant, I obediently took the iron pills and prenatal vitamins prescribed by my obstetrician. And I prescribed them for every pregnant patient I took care of as a family physician. I never questioned the practice. It seemed intuitively obvious that it was a good thing; we know pregnancy makes extra nutritional demands and depletes iron stores. It never occurred...

Listen to your science: Eat your vegetables

Guess who pioneered chemoprevention through diet?

This is an expansion of a post I did over on the Society for Science-Based Medicine blog about this time last year. The original post, which got far more traffic than is usual for the SFSBM, is a good example of how science works and the good that it can do. The hard work of real science illustrated here serves as a...

Many religions have traditions of fasting, with various restrictions. There is a good summary of those traditions on Wikipedia.

Low Energy Sweeteners and Weight Control

A new systematic review published in the International Journal of Obesity looks at the totality of evidence investigating whether consuming low energy sweeteners (LES), such as aspartame, sucralose, or stevia, is a net benefit or detriment for weight control.

Breast Milk Testing: Scaremongering, Not Science
