Oxygen metabolism is responsible for the energy production in human body however during this process it release harmful substances apart from energy production.

The by-products of oxygen metabolism are the unstable substances called free radicals which are negatively charged by acquiring electrons. Antioxidants are the essential for neutralisation of free radicals.

The small concentration of free radicals has little effects however, overloading of free radical may cause damage to DNA and cell membranes and cause several ill effects on human body.

The overloading of free radicals for prolonged period may cause improper functionality of human body as whole and may responsible for cardiovascular diseases (CVD), liver diseases and cancer in severe cases.

Antioxidants are required to neutralise the effects of oxidants on human body and protects against the ill effects of oxidants. It helps in expelling free radicals from human body and restoration of cell, tissue and organs functionality.

7 Antioxidants Rich Foods

The regular consummation of foods rich in antioxidants may avoid the overloading of oxidants in human body. Some of the antioxidants food which may help fight against free radicals are describe below.

Dark Chocolate

Dark chocolate is rich source of cocoa, essential minerals and loaded with antioxidants. The concentration of antioxidants in chocolate is much higher than we get from berries.

The FRAP analysis shows that the concentration of antioxidants in dark chocolate is 15 mmol per 100 grams compared to 9.2 mmol and 2.3 mmol in blueberries and raspberries respectively.

The essential minerals and antioxidants present in dark chocolate helps in providing other health benefits like:
