Why Do You Need Antioxidants in Your Diet?

Antioxidants prevent the oxidation, which removes them from being electrons from one molecule and another, or to prevent an oxygen molecule away, added to another atom or molecule. A simple example is the oxidation of a carbon atom, when oxidized to carbon dioxide. Removed biological antioxidants also prevent hydrogen ions from organic compounds.

When a substance such as wood (cellulose) burns,is oxidized. The carbon atoms of the cellulose can be oxidized to carbon dioxide and oxygen is reduced to water, while the energy is its chemical bonds to heat and light can be converted.

In common parlance we speak of "carbohydrate burning" to produce energy during exercise training. In this case, the sugar we eat is "burned" slowly, because even converted into carbon dioxide water and heat. But beware! No light is produced when you burn carbohydrates, no lightarises when we oxidize all types of molecules in our body. The oxidation is controlled so that the energy released slowly to the care of our body and its processes.

The first thing you learn is that the oxidation in our bodies is not always bad, and not always good. Sometimes there are advanTAGes, and other times, there are disadvanTAGes or outright losses.

The advanTAGes are obvious. If we have more energy, we need to "burn some 'of carbohydrates." We oxidize some sugars thatenergy we need on a short-term basis. We oxidize other kinds of complex carbohydrates, like glycogen, to help our bodies grow and repAir themselves.

However, some kinds of molecules in our bodies are constantly at risk of being oxidized. When this happens, they are damaged or destroyed in the process. Then we age a little bit if these other kinds of molecules are part of structures like skin, or blood vessels, or knee joints, or brain tissue, and so on. It is oxidation of this kind that we would like to prevent or slow down to prevent aging.

Unique forms of oxygen and hydrogen, called free radicals, are primary culprits of the aging process. By eating Foods that have strong antioxidant activity, we help our bodies fight the toxic effects of these free radicals.

There are three strong antioxidants that are the warriors we depend upon to fight the bad aspects of oxidation. One of them we produce in our bodies; we do not, and cannot get it from the Food we eat. Its name is glutathione, a small molecule composed of three amino acids, but don't worry; we aren't going there. Let it suffice to say that if we can't make glutathione ourselves, we are skunked. The other two antioxidant warriors are vitamins C and E. These we must get from the Foods we eat.

Good sources of Vitamin C are the fresh fruits of many kinds of plants, and some of their green parts as well. The following presents the best of these Foods in descending order from those having fruits/leaves/vegetables with the highest concentration of Vitamin C per gram of plant tissue, down to those with the lowest concentration:

o Rose (rose hips); More than 2000 mg/100 grams plant tissue.
o Black Currant, Red Pepper, Parsley, Red Guava; 100-200 mg/100 grams.
o Kiwi Fruit, Broccoli, Loganberry, Red Currant, Brussels Sprouts, Lychee, Elderberry, Persimmon, Papaya, Strawberry; 60-99 mg/100 grams tissue.
o Orange, Lemon, Cantaloupe, Cauliflower, Garlic, Grapefruit, Raspberry, Tangerine, Mandarin Orange, Spinach, Cabbage, Lime; 30-50 mg/100 grams of plant tissue.
o Mango, Blackberry, Potato, Honeydew Melon; 20-28 mg/100 grams.
o Cranberry, Tomato, Blueberry, Pineapple, Grape, Aai berry, Apricot, Plum, Watermelon, Banana, Pomegranate, Carrot, Avocado, Crabapple, Cherry, Peach, Apple, Asparagus, Pear, Lettuce, Cucumber, Eggplant, Fig; Bilberry, Horned Melon, Medlar, less than 20 mg/100 grams plant tissue.

Good sources of Vitamin E, otherwise known as Alpha Tocopherol, include the following in no special order:

o Avocado.
o Nuts of woody plants such as almonds and hazelnuts.
o Red palm oil.
o Spinach and other green leafy vegetables.
o Vegetable oils such as canola, corn, sunflower, soybean, cottonseed, and olive oil.
o Wheat germ.
o Whole grains and whole grain food products.
o Milk.
o Asparagus.

The most important lesson of this article is that it is wise to add foods that are rich in antioxidants to your diet. Put fresh fruits on your cereal in the morning, and drink a glass of fresh fruit juice as a pep-up at anytime during the day. Juices that are shaken or stirred constantly may not be as healthy due to the destruction of vitamin C. If you do not yet include fresh fruits in your diet, all such additions will help improve your health, fitness, and longevity.
