Grains and beans can be part of a healthy diet, but individual biology plays a crucial role in their effects on health, especially for those dealing with diabetes or weight issues. Opt for whole grains and ancient varieties if gluten isn't a concern, and be mindful of portion sizes. Beans are beneficial, particularly when prepared correctly to reduce potential digestive issues, and are a staple in longevity-focused diets like those found in Blue Zones.
