It may be green and leafy, but spinach is no nutritional wallflower, and you know from reading Eat This, Not That!. This noted muscle builder is a rich source of plant-based omega-3s and folate, which help reduce the risk of heart disease, stroke, and osteoporosis. Bonus: Folate also increases blood flow to the nether regions, helping to protect you against age-related sexual issues. And spinach is packed with lutein, a compound that fights macular degeneration (and may help your sex drive). Aim for 1 cup fresh spinach or 1/2 cup cooked per day.
SUBSTITUTES: Kale, bok choy, romaine lettuce
