Here is a good list of foods you want to eat if you want the best nutritional bang of the bucks. There are 29 recommended healthiest foods with information on fruits, vegetables, grains/beans/nuts, and seafood. Couple of my favorites include:

02. Avocados
The Power: Oleic acid, an unsaturated fat that helps lower overall cholesterol and raise levels of HDL, plus a good dose of fiber. One slice has 81 calories, 8 grams of fat and 3 grams of fiber. Try a few slices instead of mayonnaise to dress up your next burger.
…
04. Mango
The Power: A medium mango packs 57mg of vitamin C, almost your whole-recommended daily dose. This antioxidant helps prevent arthritis and boosts wound healing and your immune system. Mangoes also boast more than 8,000 IU of vitamin A (as beta-carotene). One mango has 135 calories, 1 gram of fat and 4 grams of fiber. Cut on up and serve it over leafy greens. Bonus: Your salad will taste like dessert!
…
11. Onions
The Power: Quercetin is one of the most powerful flavonoids (natural plant antioxidants). Studies show it helps protect against cancer. A cup (chopped) has 61 calories, 0 fat and 3 grams of fiber. Chop onions for the maximum phyto-nutrient boost, or if you hate to cry, roast them with a little olive oil and serve with rice or other vegetables.
…
16. Bok Choy (Chinese cabbage)
The Power: Brassinin, which some research suggests may help prevent breast tumors, plus indoles and isothiocyanates, which lower levels of estrogen, make this vegetable a double-barreled weapon against breast cancer. A cup will also give you 158mg of calcium (16 percent of your daily recommended requirement) to help beat osteoporosis. A cup (cooked) has 20 calories, 0 fat and 3 grams of fiber. Find it in your grocer’s produce section or an Asian market. Slice the greens and juicy white stalks, then sauté like spinach or toss into a stir-fry just before serving.
…
28. Salmon
The Power: Cold-water fish like salmon, mackerel and tuna are the best sources of omega-3 fatty acids, which help reduce the risk of cardiac disease. A 3-ounce portion (cooked) has 127 calories, 4 grams of fat, 0 fiber. Brush fillets with ginger-soy marinade and grill or broil until fish flakes easily with a fork.
