11. Turnip Greens
These beauties contain choline, an essential nutrient that helps with sleep, mood, inflammation, and memory. Store in the refrigerator for up to a week and enjoy raw or cooked. Try adding them to salads and stir-fries!
12. Broccoli
Broccoli lives up to its stellar reputation. Broccoli and broccoli sprouts are full of antioxidants and glucosinolates that make it a great cancer-fighting food. The best way to preserve its nutrition density levels is to chill it as soon as its harvested and to eat it within two or three days. At the grocery store, look for broccoli with dark green crowns. Whole heads of broccoli are more nutritious than pre-cut florets, according to Jo Robinson in Eating on the Wild Side.
