In this “Ask Me Anything” (AMA) episode, Peter and Bob talk all about sugar and sugar substitutes and provide a way to think about sugar consumption. The conversation begins by defining the various forms of sugar, delineating between added sugar and naturally occurring sugar, and describing the important variables that determine the potential for metabolic damage from consumption. They then take a dive deep into three main categories of sugar substitutes—non-nutritive sweeteners, alcohol sugars, and leaving allulose, in a class by itself—including the safety profile of each, impact on blood sugar and insulin, side-effects, taste preferences, and more.
