Raisins are dried grapes. Raisins are delightfully sweet thanks to the high sugar content of grapes. Like other dried fruit, raisins are also highly nutritious and contain many healthy substances in high concentrations. Raisins contain high levels of vitamin B complex, such as B6, which helps prevent cardiovascular disease. Raisins are also a good source of minerals, particularly iron, boron and potassium. Potassium helps lower blood pressure and boron contributes to healthy bones, because it promotes the absorption of calcium. Raisins reduce the risk of osteoporosis.
Raisins also contain phytonutrients, which have an antioxidant and anti-bacterial effect. They counter bacterial and viral infections in the mouth and thus help prevent cavities and infections.
