Healthy foods—including veggies, fruit, whole grains, nuts, seeds, and avocado—contain raw materials that either fuel the activity of your body's cells, or help maintain, heal, or regenerate tissue (such as hair, skin, immune cells, and muscle). But we don't require an unlimited supply of these nutrients. The amount your body needs is largely based on your age, sex, height, ideal body weight, and physical activity level. A young, tall, active man with a higher ideal weight, for example, requires larger portions than an older, petite, sedentary woman.
