It should be stressed that raisins can prove useful in the fight against carries, too. Although their texture is “sticky”, they contain microorganisms, which compensate for the negative effects of bacteria that cause damage to dental plaque.
Raisins are concentrated sources of metals such as calcium, iron, manganese, magnesium, copper, fluorine, and zinc. Copper and manganese are essential co-factors of superoxide dismutase, an antioxidant enzyme. 100g of raisins provide 23% of the RDA (Recommended Daily Intake) in iron. They also contain potassium which is useful for the heart as it helps the elimination of excess sodium, thus lowering hypertension. 100g of raisins provide 749 mg of potassium.
