Dietary Antioxidants Hold the Key for Optimal Health
Well, you’ve heard it umpteen times that you are what you eat. And you are probably gearing up already to redesign your food chart to throw in a few healthy choices based on the recommendations of nutritionists. In that case, you must be familiar with the term “antioxidants” – the magical word in the lexicon of health and nutrition that has become a synonym of power-houses of nutrients. After all, who wouldn’t want to look perennially young, energetic and free of ailments! Though such a proposition may sound a fantastic probability, you can turn it into a possibility by opting for a sensible diet plan that includes foods rich in antioxidants.
Antioxidants are naturally occurring chemicals in foods that help to counter the detrimental effects of oxygen free radicals, which form during normal metabolism. External factors like pollution, ultra-violet radiation and x-rays also produce free radicals that affect our system. Free radicals are deprived of oxygen and are responsible for development of serious ailments including cancer and heart disease. Antioxidants convert the free radicals into harmless waste products that are eliminated from the body before any damage is done to the body. Thus antioxidants act as scavengers that rid our body of free radicals that cause serious metabolic disorders by damaging the tissues and cells.
How do we ensure consumption of antioxidants in our everyday diet plan?
You will realize that it is not actually difficult to plan a diet rich in antioxidants. Most of the antioxidants that we require come from plants. Fruits, vegetables, nuts, legumes, cereals and seeds are foods that are naturally rich in antioxidants. The best way to ensure adequate intake of the antioxidants is to consume a variety of fruits and vegetables through a diet consisting of 5 to 8 servings of fruits and vegetables per day. Fruits and vegetables can help guard against heart disease, cancers and the effects of radiation, pollution and ageing.

Blueberries, raspberries and blackberries are rich in proanthocyanidins, antioxidants that can help prevent cancer and heart disease.
Broccoli, Cabbage, carrots, spinach, lemon, ginger, peppers, parsley, kale and red beets and tomato are vegetables rich in antioxidants. Broccoli, a cruciferous vegetable, is one of the best antioxidants. It contains more vitamin C than an orange and has more calcium than a glass of milk. In addition to minerals and vitamins, broccoli is filled with disease-fighting chemicals called phytonutrients. Sulforaphane, a phytonutrient found in broccoli, has been shown to lower the risk of many types of cancers. Tomato is the richest source of a powerful anticancer agent called lycopene.
