The Glycemic Index of Food Varies Among Individuals

Anyone who has kept tabs on the popular media’s coverage of healthcare in the US knows that Americans have been eating more and getting fatter since at least the 1950s.

Does Fructose Make You Hungrier?

Over the past several years there has been a major shift in promoting the low sugar (carbohydrate) diets over high fat diets. It’s a major shift in thinking from back when I was young and the reasons are quite complicated – it’s a dense, cautionary tale of how incomplete science, over-interpretation of data and professional …
