India also has an established traditional eating pattern which is supportive of health and good nutrition. For example, cumin seeds are extremely high in iron, and make their way into lots of Indian cuisine. The mineral content of seeds generally isn't very bioavailable, but the extensive wet grinding and precooking of spices followed by cooking with starch and acid is a nearly ideal (and quite impressive) technique to convert locked-up metal phytates to bioavailable citrates and lactates. That prehistoric Indians were able to figure this out suggests that it brought significant benefits.
