List of phytochemicals in food

While there is ample evidence to indicate the health benefits of diets rich in fruits, vegetables, legumes, whole grains and nuts, no specific food has been acknowledged by scientists and government regulatory authorities as providing a health benefit. Current medical research is focused on whether health effects could be due to specific essential nutrients or phytochemicals.^[1]

The following is a list of phytochemicals present in commonly consumed foods.
