Antioxidant Fruits


Antioxidant fruits refer to fruits containing a large amount of antioxidant substances which can help the body to fight against the damages of free radicals. These free radicals are actually molecules which will accelerate the aging process of the body and increase the risk of several diseases such as cancer, Alzheimer’s disease and other chronic diseases. The role of the antioxidants is to inhibit the reactions of free radicals and allow the maintain balance of the chemicals in the body. It is well known that prune, raisins, blueberries and cranberries are some fruits rich in antioxidants.


Every cell in our body requires oxygen to work well. However, oxygen can also result in damages on the cells that depend on it. Oxidative damages of cells are usually happening upon continuous exposure to oxygen. One famous experiment of oxidation test is to put a slice of fruit in the open air. After a period of time it will be turning to brown color. We can also apply a small amount of lemon juice on top of the fruit to prevent the fruit from changing its color. The reason is because lemon juice is a strong antioxidant which can slow down the oxidation process. Antioxidant molecules in the body has a similar effect and they can play an essential role in preventing the oxidation process of cell in the body, and they can even reverse the existing damages back.

Vitamins a, c and e is a natural source of antioxidants. These vitamins are generally achieved either through vitamin pills or via the daily food intake. Scientific studies already confirmed that the antioxidant in natural fruits will be more easily be absorbed by the human body. These vitamins are able to protect and heal the damages on cells in various organs including brain, lungs, spinal cord tissue and so on.

Scientists usually identify the ability of antioxidant-rich foods by the oxygen radical absorbance capacity (ORAC) factor. Some fruits and vegetables have a higher ORAC factor than other foods. The best antioxidant fruits in the list include Brazil berries, plums, pomegranates, grapes, blueberries, blackberries, cranberries, strawberries etc. Although there is no direct evidence to prove that antioxidant-rich fruits and vegetables can cure cancer and other diseases, regular consumption of them in our daily diet can surely promote good health. Recent studies found that nine servings of fruits and vegetables a day can have access to the most abundant dietary antioxidants. In addition, most doctors suggest that people who have a family history of cancer to eat more antioxidant fruits and vegetables in their daily diets.
