Have you ever noticed that when you slice an apple it quickly turns brown? That’s the result of a process called oxidation. it happens to all cells in nature, including ones in your body. To help your body protect itself from the rigors of oxidation, there are thousands of antioxidants in fruits, vegetables, whole grains, nuts and legumes and also in supplements.
The other concept we need to get our head around is free radicals. Oxidation happens just by breathing, exercising,or breaking down food and it creates FREE RADICALS. These are very unstable molecules with unpaired electrons. They are “free” because they are missing a critical electron, which sends them a riot to find them another to pair its unpaired electron. To do this, they go on attack, they don’t just kill other cells to acquire the missing electron but they injure the DNA, creating a seed for disease in the body, by mutation. The DNA grows abnormally, reproduces abnormally, quickly, leading to health problems.
This occurs in a chain reaction that can lead to various effects of ageing and degenerative diseases, especially cancer. A different chain reaction leads to wrinkles. Free radicals can also oxidize fat (LDL) triggering the formation of plaque in arteries, leading to heart disease and stroke.
The main antioxidants are vitamin E, beta-carotene, vitamin C, and Selenium
