Vitamin C, E, selenium

This works similar to an old trick from Grandma's kitchen: Sprinkle some lemon juice on freshly cut fruit and it won't turn brown. That is because the oxidation process is stopped. Just that here the ingredients in the lemon juice react with air instead of fruit. The lemon juice acts similar to an antioxidant ingredient. That is exactly the process that happens millions of times in the human body. Vitamins protect the body and the cell structures from the free radicals in the air and the immediate environment. The operating principle of the vitamins is similar to that of the lemon juice. They support the cell nutrionally against aggressive, free radicals. Just like the lemon juice, a certain part gets used up and therefore must be consumed in our diet.
