Nutrition Zeroes or Heroes? Four Misunderstood Foods

While superfoods like blueberries, tomatoes and spinach have achieved the nutrition equivalent of celebrity status, other fruits and vegetables generate little excitement - and even confusion.

The researchers and scientists at the Dole Nutrition Institute took another look at several foods commonly regarded as "nutrition zeroes" and found out that some of them are actually "nutrition heroes." Here is a list of four under-appreciated - and even misunderstood - fruits and veggies that deserve a place on your plate:

* Avocados: Some of the smartest folks I know avoid avocados as "high fat" foods, but the monounsaturated fat in avocados protects your heart by lowering LDL "bad" cholesterol while raising HDL "good" cholesterol. Avocados also contain fiber and the phytonutrient beta-sitosterol, which also help control cholesterol, and lutein, which promotes eye health.

Looking for a food source of vitamin E? Avocados have the highest gram-per-gram content of this powerful antioxidant. Finally, if there was a "superfood for your liver" category, avocados just might qualify. In one Japanese study, avocados beat out 22 other fruits as the best defense against liver damage.

* Celery: A dieter's standby, celery is often dismissed as a nutrition nonentity. But it turns out that two stalks provide an excellent source of vitamin K and a good source of vitamin C, folate and potassium - all for just 20 calories. Celery is also loaded with phytonutrients such as quercetin, which promotes prostate and brain health, and apigenin, which may help slow prostate tumor growth.

* Parsley: Regarded as little more than a garnish, parsley actually packs a powerful nutrition punch. Just 1/4 cup provides more than 300 percent of the Daily Value of vitamin K and contains an excellent source of vitamins A and C.

Parsley is also a top source of the antioxidant flavonoid apigenin, which, in addition to protecting the prostate, may also help reduce the risk of breast, colon, skin and thyroid cancers. Parsley's abundance of phytonutrients - beta-carotene, lutein and zeaxanthin - can help safeguard your sight, and chewing on a sprig can help freshen your breath.

* Potatoes: The fact that spuds are America's favorite vegetables wouldn't be so bad if they weren't usually deep-fried, processed and drowned in saturated fat. In fact, a medium baked potato with skin has 163 calories, no fat, and provides an excellent source of potassium and vitamin C, plus a good source of fiber, magnesium, copper, manganese, niacin, vitamin B-6 and folate.

Availability: Usually ships in 24 hours See Reviews For This Product Description Vitamin C is also known as ascorbic acid and is a water-soluble, antioxidant vitamin that plays a role in more than 300 bodily functions. It is essential to help support health and wellness and requires daily replenishment. Unfortunately, human beings unlike other animals cannot manufacture vitamin C. Nor can they store vitamin C to any appreciable amount. Instead, the kidneys, acting as regulators, excrete vitamin C causing the need for regular replenishment. In addition, vitamin C is destroyed during food preparation. Vitamin C is essential in helping to maintain collagen, a protein necessary for forming skin, ligaments, bones, and teeth and for helping to maintain the strength of blood vessel walls. High levels of vitamin C are also essential for the metabolism of white blood cells, which are critical components of the immune system. In addition, vitamin C plays and important role in the absorption of iron, which is necessary for the formation of red blood cells and in the utilizationi of folic acid, one of the B-complex vitamins.
