David Perlmutter, a leading neurologist and author, and Rick Johnson, a physician and researcher, dive into the controversial topics of fructose and uric acid. They debate whether these substances truly drive poor metabolic health or if their roles are misunderstood. Fructose, they argue, can be protective in the liver, increasing ATP availability rather than depleting it. The discussion challenges common myths about sugar, emphasizing the need for context when considering its effects on metabolism and health.
