(CNN)Dietary supplements and so-called "superfoods" have become big business in the food, health and sports nutrition industries, bringing connotations of health, wellbeing and overall improvement -- both physically and mentally.

But the term superfood is not recognized clinically nor readily acknowledged among nutrition experts and the evidence for supplementation has now moved in favor of balanced diets over popping pills of single nutrients.
Experts maintain that the right diet can not only control weight, but also help to keep diseases at bay by fighting the stressors our bodies encounter on a regular basis, including lack of sleep, poor diet, lack of exercise and general stress at work. These stressors can reduce our physical and mental performance and even lead to chronic diseases such as heart failure or diabetes.
    So rather than which foods are "super," we asked experts which foods are useful to include as part of a balanced diet, to keep our bodies fit and healthy.
