Antioxidants Naturally Found in Foods

Saturday, April 10th, 2010

Why do we need to eat foods that are found to be naturally high in antioxidants?
What are antioxidants?
Which foods do we need to eat, in order to naturally fight free radicals?

Scientists have found that the body forms unstable oxygen molecules, called free radicals; every cell produces tens of thousands of them each day. A free radical is basically an atom with an odd number of electrons in its outer ring. Since electrons have a very strong tendency to exist in a paired rather than an unpaired state, free radicals indiscriminately pick up electrons from other atoms, which in turn convert those other atoms into secondary free radicals, thus setting up a chain reaction, which can cause substantial biological damage. This, in short, is bad. There are also many kinds of free radicals, which we are exposed to everyday, for example, pollution, radiation, cigarette smoke and herbicides.

Antioxidants are thought to neutralise and stabilise these free radicals.

So, which antioxidants are naturally found in which foods?

We have:

Vitamin E: a fat-soluble vitamin found in vegetable oils, nuts, green leafy vegetables, and fortified cereals. Some of the foods containing the highest amounts of vitamin E are wheat germ oil, almonds, sunflower seeds, sunflower oil, hazelnuts, peanuts, spinach, broccoli, kiwi and mango.
Vitamin E is an antioxidant vitamin involved in the metabolism of all cells. It protects vitamin A and essential fatty acids from oxidation in the body cells and prevents breakdown of body tissues.

Vitamin C: Ascorbic acid is a water-soluble vitamin present in citrus fruits and juices, cabbage, green peppers, broccoli, spinach, tomato, kale, guava, cantaloupe, kiwi, papaya, and strawberries.
It is important in forming collagen, a protein that gives structure to bones, cartilage, muscle, and blood vessels. Vitamin C also aids in the absorption of iron, and helps maintain capillaries, bones, and teeth.

Antioxidants: Eat All Your Colors!

Saturday, March 20th, 2010

Antioxidants are all the rage today. And, justifiably so. Antioxidants help neutralize free radicals which cause cell damage, which ultimately can lead to diseases of the heart and cancer. It seems everywhere you go its blueberry this and blueberry that. You have your choice of wild blueberry juice, blueberry-pomegranate juice, blueberry-cranberry juice and so on and so on.

Now, don’t get me wrong. I love blueberries. But, in our rush to embrace the latest antioxidant food craze (blueberries, cranberries, pomegranates) we’re ignoring some very high-antioxidant foods that are probably sitting ignored in our cupboards.

“What?” You ask, “What could possibly be higher in antioxidants than my beloved wild blueberry?” Well, how about the small red bean? That’s right, I said “bean.” The small red bean actually has more antioxidants per serving size than the wild blueberry. And the red kidney bean and pinto bean have more antioxidants per serving size than a serving of cultivated blueberries.

What other foods are high in antioxidants? For starters, there are artichoke hearts, blackberries, prunes, pecans, spinach, kale, russet potatoes and plums. And, no, that’s not a mistake. Russet potatoes are on the list of foods high in antioxidants.

Antioxidant

Wednesday, February 17th, 2010

An antioxidant is a chemical that reduces the rate of particular oxidation reactions in a specific context, where oxidation reactions are chemical reactions that involve the transfer of electrons from a substance to an oxidising agent.

Antioxidants are particularly important in the context of organic chemistry and biology: all living cells contain complex systems of antioxidant chemicals and/or enzymes to prevent chemical damage to the cells’ components by oxidation. The importance and complexity of antioxidants in biology is reflected in a medical literature of more than 142,000 scholarly articles.

A diet containing antioxidants from plants are required for good health since plants are an important source of organic antioxidant chemicals. Antioxidants are widely used as ingredients in dietary supplements that are used for health purposes such as preventing cancer and heart disease. However, while many studies have suggested benefits for antioxidant supplements, several large clinical trials have failed to clearly demonstrate a benefit for the formulations tested, and excess supplementation may be harmful.

Antioxidants are chemicals that reduce oxidative damage to cells and biochemicals. Researchers have found high correlation between oxidative damage and the occurrence of disease. For example, LDL oxidation is associated with cardiovascular disease. The process leading to atherogenesis, artherosclerosis, and cardiovascular disease is complex, involving multiple chemical pathways and networks, but the precursor is LDL oxidation by free radicals, resulting in inflammation and formation of plaques.

Anti-Aging Goji Juice

Friday, January 29th, 2010

The Fountain of Youth had just been discovered. Imagine, you being healthy and alive, growing old in years, but amazingly looking young and fit.

The Tibetan Goji berry and its juice contain 4 very unique Polysaccharides which are known to be Anti-aging. Besides being loaded with vitamins, minerals and anti-oxidants it is these 4 unique Polysaccharides found in NO OTHER PLANT ON EARTH that give Goji its anti-aging ability.

The longest living people on earth consumed Goji in soups, drinks and berries everyday of their lives and they live well over 100 years old and not in a debilitating way but active and vital lives. They also dined on fresh vegetables, fruits and consumed a minimal amount of animal fats. These people had no processed refined chemical foods or fast foods in their diets, living in some of the harshest and remote areas on earth.

The Goji Berry (Lycium Barbarum):

The goji berry has been used in traditional Tibetan medicine for centuries! The plants grow like bushes with vines that reach over 15 feet. The berries are never touched by hand as they will oxidize and turn black if touched while fresh. They are shaken onto mats, then dried in the shade.
