The Humble Glycemic Index Marks Global Diabetes Risk

June 7, 2019 — It’s been a wild ride. Almost 40 years ago, David Jenkins published the first paper to propose that the glycemic index of foods might be an important measure of nutrition quality.

Told Ya So: It’s the Ultra-Processed Food

May 17, 2019 — Kevin Hall is a bit of a myth buster. In a number of studies, he has put popular ideas about obesity and nutrition under the microscope of objective data.
