How Antioxidants Naturally Found in Foods

Why do we need to 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 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 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 vessels. Vitamin C also aids in the absorption of iron, and helps maintain capillaries, bones, and teeth.

Beta-carotene: Beta-carotene is a precursor to vitamin A. It is present in liver, egg yolk, milk, butter, spinach, carrots, squash, broccoli, yams, tomato, cantaloupe, peaches, and grains.

Studies have been done on beta-carotene’s for heart disease, cancer, chronic fatigue syndrome, Alzheimer’s disease, fibromyalgia, male infertility, and psoriasis.

Coenzyme Q10: CoQ10 boosts energy, enhances the immune system, and acts as an antioxidant. A growing body of research suggests that coenzyme Q10 may help prevent or treat some of the following conditions: heart disease, high blood pressure, high cholesterol, diabetes, and others. Primary dietary sources of CoQ10 include oily fish, organ meats such as liver, spinach, broccoli, peanuts, wheat germ and whole grains. Read more…

The Knowledge About Antioxidant

An 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 containing antioxidants from plants are required for good since plants are an important source of organic antioxidant chemicals. Antioxidants are widely used as ingredients in dietary supplements that are used for purposes such as preventing cancer and heart disease. However, while many studies have suggested 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.

Research suggests that consumption of antioxidant-rich reduces damage to cells and biochemicals from free radicals. This may slow down, prevent, or even reverse certain diseases that result from cellular damage, and perhaps even slow down the natural aging process.

Since the discovery of vitamins, it has been recognized that antioxidants in the diet are essential for healthful lives. More recently, a large body of evidence has accumulated that suggests supplementation of the diet with various kinds of antioxidants can improve health and extend life. Read more…

How To Get More Antioxidants Into Your Diet

It’s no secret that are incredibly beneficial to good . It’s believed the in can help prevent cancer, reverse or slow aging, enhance your immune system, increase your energy and improve heart and other organ health.

Given all we know about antioxidants and their beneficial properties, it’s amazing more people don’t get enough fruits and vegetables, the primary sources of antioxidants. Experts recommend a minimum of 5 servings of fruits and vegetables daily, but say getting 7-10 servings is best.

There are 10 steps to getting more antioxidants into your .

1.Breakfast

Breakfast doesn’t have to be a hurried toaster tart on the way out the door. Throw some strawberries, 100% juice and yogurt into a blender; pour your delicious mixture into a cup and head out the door. You’re just added one to three servings of fruits to your daily intake. Or throw some berries onto your cold or hot cereal. Read more…
