Leafy Greens

Don't miss out on powerhouse greens like kale, collards, spinach, turnip greens, and Swiss chard. These standout leafy greens are jam-packed with vitamins A, C, and K, folate, potassium, magnesium, calcium, iron, lutein, and fiber. Serve with a splash of lemon juice or red wine vinegar.

I like mine with balsamic vineger and olive oil!

Watermelon

Watermelon is a heavyweight in the nutrient department. A standard serving (about 2 cups) has 1/3 of a day's vitamins A and C and a nice shot of potassium for only 85 fat-free, salt-free calories. And when they're in season, watermelons are often locally grown, which means they may have smaller carbon footprints than some other fruits.

Garbanzo Beans

All beans are good beans. They're rich in protein, fiber, iron, magnesium, potassium, and zinc. But garbanzos stand out because they're so versatile. Just drain, rinse, and toss a handful on your green salad; throw them into vegetable stews, curries, and soups; mix them with brown rice, whole wheat couscous, bulgur, or other whole grains.

Unsweetened Yogurt

Plain yogurt has a pleasant tartness that's a perfect foil for the natural sweetness of berries, bananas, or for your favorite breakfast cereal. It has more protein, potassium, calcium, zinc, and vitamins B6 and B12 than sweetened yogurt. That's because it doesn't have to share the container with the sugary preserves or the sugar that's in many flavored yogurts.

Most yogurts are also full of live and active cultures, healthy bacteria that is great for a healthy gut! Try kefir as well, a drinkable yogurt with even more benefits than yogurt, because it is fermented!

Mangoes

Just one cup of mango supplies 3/4 of a day's vitamin A, a decent dose of blood pressure-lowering potassium, and 3 grams of fiber! Bonus: mango is one of the fruits least likely to have harmful pesticide residue.

Sweet Potatoes

A Nutritional All Star--one of the best vegetables you can eat! They're loaded with carotenoids, vitamin C, potassium, and fiber. Bake and then mix in some unsweetened applesauce or crushed pineapple for extra moisture and sweetness. From Nutrition Action Healthletter
