Fight radicals, eat anti-oxidant foods

From being disease fighters to immune boosters to an antidote to ageing, 'antioxidants' such as apples and pears can do wonders to your body Chandrika Mahendra What is an antioxidant? Picture an apple or a broccoli that turns brown when keep it outside or a metal that rusts over time. This discoloration or rusting scientifically termed as oxidation is similar to something that goes on inside our body. The radicals are like scavengers who feast on the cells and tissues in our body and corrode them.

How exactly do antioxidants work? Since free radicals are usually energy-starved, antioxidants provide the extra energy required by the radicals to prevent them from feeding on the cells for energy. In scientific terms this is called 'Neutralisation'. Where can you find these superfoods? Many food substances, fresh vegetables and fruits are good source of antioxidants. They are found in large amounts in carrots, pomegranate, green leafy vegetables like spinach, berries, cherries and grapes, citrus fruits like oranges, apples and pears etc.

Why are they important for your oral cavity? Our gum tissues suffer from radical attack due to bacterial infection. When oxidation occurs in foods, they release radicals that are harmful to gum tissues. The leftover food particles in the mouth also contribute to the oxidation. It is very important to ensure your body has a continuous supply of antioxidant-rich food to fight against radicals. Another important factor is to ensure you keep your oral cavity clean by brushing, flossing and rinsing your mouth regularly. Use toothpaste enriched with antioxidants.
