Biodiverse diets and human health

Proceedings of the National Academy of Sciences

Based on dietary data from 6,226 participants in rural areas from seven low-income and middle-income countries, a study reports that dietary quality increased with dietary species richness, that children generally had less diverse diets than women, and that dietary nutrient adequacy increased significantly with each additional species consumed, suggesting that food biodiversity may increase diet quality in vulnerable populations in biodiverse regions.
