The term “nutraceuticals” has been introduced in 1989 referring to food or part of food that can be of plant or animal origin to exert a valuable pharmaceutical activity in addition to its nutritional value. For instance, green tea is recognized for its anti-obesity and cardioprotective effects, while garlic is used for its antihypertensive effect, in addition to citrus juice and pectin which are well known for their hypolipidemic activities.
