Given the importance of antioxidant-rich food in the promotion of health and the prevention against damages caused by reactive species, this paper presents insights into the antioxidant activity of phenolics, total phenolics and antioxidants in fruits and vegetables. It also comprises the daily intake of phenolics and antioxidants from foods in the American and French diets, and the evaluation of Montenegro by using literature data. In comparison to fruit, vegetables contribute less in the daily intake of phenolics and antioxidants. In the Montenegrin diet, the main dietary sources of phenolics and antioxidants are apples and potatoes, and relatively high daily intakes are achieved from bananas, plums, oranges, bell peppers and cabbage. The daily consumption of fruit and vegetables in Montenegro is significantly lower than in France, and especially the USA. Dietary modification through the balanced consumption of fruit and vegetables is necessary. Therefore, it is more important and more effective than taking nutritional supplements for the primary prevention of chronic diseases.
