2) Avocado
Health-conscious Americans are familiar with avocados, which are high in monounsaturated fat and widely touted as a heart-healthy food. What they may not know is that avocados also contain beta-sitosterol, a plant sterol that can help lower LDL or bad cholesterol. Avocados have also been shown to reduce inflammation, another major risk factor for heart disease. You can get all of these benefits from just half an avocado at lunch—and bonus points if you pair it with guacamole!
