Polyphenols are naturally occurring compounds found
largely in the fruits, vegetables, cereals and beverages. Fruits like grapes,
apple, pear, cherries and berries contains up to 200–300 mg polyphenols per 100
grams fresh weight.
The products manufactured from these fruits, also contain
polyphenols in significant amounts. Typically a glass of red wine or a cup of
tea or coffee contains about 100 mg polyphenols. Cereals, dry legumes and
chocolate also contribute to the polyphenolic intake.
Epidemiological studies and associated meta-analyses
strongly suggest that long term consumption of diets rich in plant polyphenols
offer protection against development of cancers, cardiovascular diseases,
diabetes, osteoporosis and neurodegenerative diseases.
