The efficiency of added antioxidants in foods depends very much on the food composition, microstructure, and moisture content. A Healthy Diet that Contains Antioxidants When people eat a healthy diet, they get sufficient amounts of antioxidants, and it comprises a combination of vegetables and fruits.

Antioxidants prevent the oxidation of foods containing fats and oils. These are some examples of antioxidant food additives: Ascorbic acid (E300), or vitamin C, is found in many different fruits.
