Some foods naturally contain disease-fighting, health promoting properties, while others contain elements that may hinder your health goals.
Asparagus
Asparagus is high in glutathione, an important anticarcinogen. It also contains rutin, which protects small blood 
vessels from rupturing and may protect against radiation. Asparagus is a good source of vitamins A, C and E, B-complex vitamins, potassium and zinc.
Avocado
Avocados are rich in monounsaturated fat, which is easily burned for energy. An avocado has more than twice as much potassium as a banana. For a delicious, creamy salad dressing, mix together avocado and fresh carrot juice.
Bananas
You don’t need to eat bananas for the potassium! (Although it is present in bananas, potassium is the predominant nutrient among most all fruits and vegetables.) Bananas are high in sugar, so they should not be eaten if you have blood sugar problems. Don’t eat bananas on an empty stomach; combining them with a bit of protein will help to normalize the insulin response caused by the sugar in the banana. Green-tipped bananas are better for your health than over-ripe bananas.
Beet Greens/Root
Beet greens contain notable amounts of calcium, iron, magnesium and phosphorus. They also contain vitamins A, B-complex and C. Beet roots are high in carbohydrate levels and should therefore be used sparingly.
Broccoli
Broccoli contains twice the vitamin C of an orange. It has almost as much calcium as whole milk--and the calcium is better absorbed. It contains selenium, a mineral that has been found to have anti-cancer and anti-viral properties. Broccoli is a modest source of vitamin A and alpha-tocopherol vitamin E. It also has antioxidant properties.
