The claim that eating chocolate can extend life stems from a study in the Journal of the Academy of Nutrition and Dietetics, which found a link between chocolate consumption and lower mortality risk in post-menopausal women. However, it's important to remember that correlation doesn’t equal causation. While chocolate, especially dark chocolate, has health benefits due to its flavonoids, the study also noted that other lifestyle factors might influence the results. The researchers stressed that more studies are needed to fully understand the relationship between chocolate intake and longevity.
