They are important sources of many nutrients, including potassium, fiber and vitamin C, that promote good health and may reduce the risk of some chronic conditions like heart disease. Aim to eat at least 2.5 cups (or equivalent) every day, per the USDA's dietary guidelines. What equals 1 cup? In general, 1 cup of raw or cooked vegetables or 2 cups of raw leafy greens.
