This can be illustrated by comparing two recent... Continue Reading →

Dietary intervention studies as a whole are inherently flawed and do not produce causal or clinically relevant health recommendations or decisions. Accuracy and replicability of any study depend upon using precise methods under identical conditions using identical materials, reagents, apparatus, and test subjects. Unfortunately, human dietary intervention studies in the scientific literature are fatally confounded... Continue Reading →
