Seven Best Foods

Many opinions exist about what makes a food good, better or best. Some use taste as the defining factor, others ease of preparation. Affordability and availability are other criteria frequently involved in judging a food's worth. But if you are talking about nutrient density, or the amount of vitamins, minerals, antioxidants and fiber that you get for a serving of a food, those which are by far the most nutritious, according to Joel Fuhrman, M.D., in his book "Eat for Health," are almost exclusively leafy greens.

Mustard Greens

Mustard greens are pungent members of the cruciferous family of vegetables, whose seeds are used to make the condiment mustard. One cup of mustard greens contains only 15 calories, and is an excellent source of many nutrients, including the vitamins A, C, K, E and folate, in addition to the minerals manganese and calcium. According to Dr. Fuhrman, who has evaluated the total nutrient value of hundreds of foods and compared them on a numerical scale of 1 to 1,000, mustard greens earn a perfect score.

Kale

Kale is a cruciferous vegetable whose nutritional value makes it a worthy inclusion to your weekly shopping list. Kale has levels of nutrients comparable to mustard greens. It is a very good source of fiber and calcium, and like other leafy greens kale is a good source of omega-3 fatty acids. Kale also has a nutrient density score of 1,000.

Collard Greens

Collard greens are another low-calorie leafy green vegetable with a nutrient density score of 1,000. At a mere 60 calories per 5 oz. serving, collard greens are a perfect addition to salads and steams if you are budgeting calories, and with over 40 percent of calories coming from protein, collard greens are a perfect muscle food.

Spinach

Spinach is not just for Popeye, although if you want his forearms, this leafy green is for you. Over half of the calories in spinach come from protein, and 1 cup of spinach, at only 7 calories, provides over 180 percent of the daily requirement for vitamin K, important for blood clotting, and over half your daily requirement for vitamin A, necessary for healthy vision.

Brussels Sprouts

Although they look like miniature cabbages, Brussels sprouts are anything but puny when it comes to nutritional punch. Along with the antioxidant vitamins A, C and E, Brussels sprouts are very rich in vitamin K, folate and fiber, similar to their cruciferous kin, kale and mustard greens.

Swiss Chard

Swiss chard may not be as readily-available as spinach, but calorie for calorie, this tall, leafy vegetable with a thick, crunchy stem is one of the most nutritious of all vegetables, which makes it one of the best foods around. It is a rich source of many newly discovered phytonutrients, essential compounds present only in plants, and it is a concentrated source of the carotenoids, anti-oxidant compounds such as beta-carotene, which slow cellular aging.

Bok Choy

Bok choy is a frequent addition to Asian dishes, and like collard greens it is packed with protein, with over 10 grams of protein per 100 calories. Bok choy has a very mild flavor and a higher concentration of beta-carotene and vitamin A than any other cabbage. It is also a good source of potassium, important for the maintenance of normal blood pressure. Bok choy earns a nutrient value of 824, by Fuhrman's scoring method.
