According to a study in the American Journal of Clinical Nutrition, men eating from how many food groups were associated with a 50% excess mortality risk?

The correct answer reflects findings that indicate men consuming from two or fewer food groups are associated with a significantly increased risk of mortality. This highlights the importance of dietary variety for health. Eating from a limited number of food groups can result in nutritional deficiencies, as it is challenging to obtain all necessary nutrients from such a restricted diet. The study underscores that insufficient dietary diversity may lead to adverse health outcomes, including increased risk of chronic diseases and, ultimately, higher mortality rates.

It is essential for individuals, especially men as highlighted in the study, to aim for a well-rounded diet that incorporates a wide array of food groups. This approach not only supports overall health and well-being but also promotes longevity by reducing the risk associated with a monotonous diet.
