Fruit and vegetables antioxidants have been recognized as important compounds that reduce the risk of several chronic
diseases (Lampe, 1999).
Data from epidemiological studies have shown an inverse association between the consumption of fruits and vegetables and the incidence of various diseases, such as cardiovascular, ophthalmological and gastrointestinal diseases, neurodegenerative disorders, and some types of cancer (Van Duyn and Pivonka, 2000).
Current scientific evidence also suggests a protective role of fruits and vegetables in stroke and the prevention of coronary heart disease.
In addition, new scientific evidence supports a protective role for fruits and vegetables in the prevention of cataract formation, chronic obstructive pulmonary disease, diverticulosis, and, possibly, hypertension (Van Duyn and Pivonka, 2000).
