Longevity expert David Céspedes suggests that individuals should freeze bread before consuming it. According to the specialist, this process encourages the formation of specific starches. These modified starches are considered highly beneficial for the body's microbiota. By altering the bread's structure through freezing, the nutritional impact on the gut is improved. This simple dietary adjustment is presented as a way to support overall digestive health. The recommendation focuses on the biochemical changes that occur during the freezing and subsequent eating process. Such practices are linked to broader strategies for promoting longevity and wellness.
