These antioxidant enzymes neutralize many types of disease-causing free radicals, ridding the body of their harmful effects. Supplements of these antioxidant enzymes are also available. Usually they are for oral administration in the form of pills or capsules. However, the absorption of antioxidant enzymes in supplement form is minimal at best. The antioxidant substances found in antioxidant fruits may work to neutralize these free radicals and in the process prevent them from causing damage. Antioxidant Fruits: The Benefits Many people are already familiar with antioxidant fruits, such as citrus fruits which are known for their high vitamin C content or apples for their beta-carotene. Oxidation is a natural process that occurs in the human body as well. Our cells need oxidation in order to undergo metabolism of fats and glucose so they can turn into heat and energy. Oxidation is a vital part of life. But as vital as oxidation is, it can also have some negative effects on the body. They are also loaded with healing antioxidants, which of course make them excellent antioxidant foods. There are several kinds of berries, as you well know, and each kind has a different concentration of antioxidants. In recent studies, purple berries (such as Elderberry and black currant) are considered as the richest antioxidant foods. With the use of a much more precise method than the one used in 1999, the study found that the dietary antioxidants found in honey are equal to those in many fruits and vegetables in their ability to counter the degenerating activity of highly reactive molecules known as free radicals. "It's still too early to say definitely, but honey seems to have potential to serve as a dietary antioxidant," Engeseth said. In the study about antioxidant juice from pomegranates, researchers have found that the substance can effectively reverse the progression of atherosclerosis, or the hardening of the arteries. Atherosclerosis causes decreased blood flow that can lead to heart attacks or strokes. The tests showed that antioxidant juice from pomegranates reduced the effects of stress on human blood vessel cells by stimulating the production of nitric oxide.
