Functional foods are foods that have a potentially good effect on health beyond basic nutrition. Proponents of functional foods are they promote maximum health and help reduce the risk of disease. Functional foods range from cereals and bars enriched with folic acid to your average tomato or cup of green tea, while nutraceuticals are more commonly sold in pill form. The level of consumption of the food that is required to achieve a beneficial effect on health is an important consideration. Human nutrition, process by which substances in food are transformed into body tissues and provide energy for the full range of physical and mental activities that make up human life. The study of human nutrition is interdisciplinary in character, involving not only physiology, biochemistry, and molecular biology but also fields such as psychology and anthropology, which explore the influence of attitudes, beliefs, preferences, and cultural traditions on food choices. Human nutrition further touches on economics and political science as the world community recognizes and responds to the suffering and death caused by malnutrition.
