In this “Ask Me Anything” (AMA) episode, Peter explains how to evaluate sugar & its substitutes in the context of health. Peter explores the role of sweeteners in three common use-cases – beverages, protein supplements, & sweet treats & breaks down how our evolutionary craving for sweetness now clashes with today’s food environment. He examines whether sugar is uniquely fattening, the hormonal effects of sugar consumption, & the significance of timing in sugar intake. The episode compares natural versus refined sugars, sugar in beverages versus in solid foods, & the pros & cons of popular sweeteners including saccharin, aspartame, sucralose, allulose, & sugar alcohols like erythritol & xylitol. With a focus on weight management, glycemic impact, gut health, & long-term safety, this episode offers a comprehensive guide to navigating the sweetener landscape with clarity & nuance.
