When anti-oxidants enter the body, they repel the free radicals that are responsible for the oxidation process within cells. The process is slowed down, or completely stopped. These substances also aid in the repair of damaged cells, resulting in the healing of different ailments, including heart conditions and diabetes. Certain types of cancerous cells are prevented from growing and developing too. The metabolism is improved and certain attributes are enhanced. With the removal of free radicals and toxins, the aging process gets delayed.

You might wonder why oxidation is so bad for the body, considering that oxygen is what gives us life. Well, under normal circumstances, oxidation is a very natural process that can only benefit, and not harm. Additionally, it is vital for the proper functioning of all the bodily systems. But unnecessary oxidation prompted by the entry of free radicals causes immense harm. These free radicals or unstable molecules find an entry via contaminated food and water, polluted air, stress and hectic lifestyles.

Brazilians consume the Acai berry as a fruit, and remain young. Other parts of the globe refuse to include these berries in their diet; they prefer them as ingredients of anti-aging products instead. Other berries are good for health too. Grape skins are a wonderful source of anti-oxidants too—so consumption of grapes is good for health. The French maintain an ideal weight by combating the harmful effects of foodstuffs rich in cholesterol with Red wine! Coffee comes with natural anti-oxidants, but because of the various things that are mixed with it, its healing power comes down.

Now, plants and animals do not have to worry like us. Their bodies contain multiple kinds of anti-oxidants. The whole thing works like this—the majority of plants contain substances known as Sterols. When herbivores consume these plants, they get the Sterols into their bodies. They also benefit from enzymes like certain Peroxides, Superoxide, Catalase and Dismutase. It goes without saying that vitamins, especially C and E, enter the animals' stomachs too. The carnivores that feed on these herbivores get the same benefit, in their turn. Thus, plants and animals maintain natural, but rather complex anti-oxidant systems within themselves.

If you wish to follow in their footsteps, go in for plenty of fruits and vegetables so that you store up on vitamins and minerals. You will also get useful amino acids, fatty acids and omega 3, 6 and 9. Certain plant products can provide large concentrations of Glutathione and Resveratrol, along with Sterols—these are good too.

Considering that anti-oxidants are good at repair and preservation, they are valuable gifts to the cosmetic industry and the food industry. Even industries use them for preventing degradation.

You may consume substances containing anti-oxidants in any form—tablets, capsules, dietary supplements, or energy drinks. And if all these forms are unpalatable to you, go in for cosmetic products rich in anti-oxidants. Yes, they come a tad expensive, but do not skimp on something that is so vital for your good health.
