Sesame Seeds

Tiny, tasty sesame seeds contain unique lignans (or plant compounds), including sesamin and sesamolin, which can help lower cholesterol. The seeds are a good source of calcium, phosphorous, and zinc—as well as copper, which research suggests may help maintain strong bones.

Walnuts

Of all nuts, walnuts contain the most alpha-linolenic omega-3 fatty acids, which lower LDL (bad) cholesterol and may reduce inflammation in arteries. Walnuts are also a great source of antioxidants, vitamin E, selenium, and magnesium.

Dark Chocolate

It's just like chocolate to crash the party, but it's no mistake that the dark variety confers health benefits. Dr. Aviva Romm, President of the American Herbalists Guild, says that the high antioxidant levels make it a perfect indulgence. Chocolate is high in flavonoids, substances that have been shown to improve blood flow, suppress coughs, improve memory, and give you hydrated, smooth skin. A 1 oz. dose of chocolate a day is now officially the doctor's order.

Seaweed (Hijiki, Wakame, Kelp, Nori)

Think of eating seaweed as going directly to the source—this is where fish procure their Omega-3's, meaning you can skip the fish and go straight to the seaweed. Seaweeds are also a two-for-one deal, nutrition-wise: They contain nutrients commonly found in green, leafy vegetables, along with most minerals found in the ocean. They're also full of magnesium, which may prevent migraines and asthma attacks. Grate nori on popcorn and eggs, add wakame to soups, and marinate hijiki with sesame oil for a quick salad.

Yogurt

Like the milk it's made from, yogurt is a very good source of calcium, phosphorus, and protein. Unlike milk, real yogurt also contains probiotics, the good bacteria your digestive system needs to process and benefit from all the other things you eat. One, Lactobacillus casei, boosts immune response
