Why Are Leafy Green Vegetables Important in Epidemiology?

Leafy green vegetables are a significant part of the human diet due to their high content of vitamins, minerals, and dietary fiber. Epidemiological studies have shown that regular consumption of these vegetables is associated with reduced risks of chronic diseases such as cardiovascular disease, type 2 diabetes, and certain cancers. For example, the antioxidants found in leafy greens can reduce oxidative stress and inflammation, which are underlying causes of many chronic conditions.
