Eating an apple a day without removing the peel can help stave off high blood pressure, say researchers.
Canadian scientists have found that the fruit is more effective than other "superfoods" including green tea and blueberries as a source of antioxidants and chemical compounds called flavonoids that combat the potentially life-threatening condition.
In a study, researchers from Nova Scotia Agricultural College tested the peel and the fleshy fruit of apples separately.
The peel was found to be up to six times more effective in inhibiting an enzyme called ACE, which is known to cause hypertension and high blood pressure, according to the team's results in the journal Food Chemistry.
"Apples are one of the most popular and frequently consumed fruits in the world," the Daily Express quoted the researchers as stating.
"Apple peel is a rich source of flavonoids which provide numerous health benefits - apple peel flavonoids inhibited the enzyme ACE," they added.
