Apples are a popular fruit, containing antioxidants, vitamins, dietary fiber, and a range of other nutrients. Due to their varied nutrient content, they may help prevent several health conditions.There is overwhelming evidence that one-third of all cancer cases and half the incidences of cardiovascular disease and hypertension can be attributed to diet. Because apples are high in potassium, a mineral that helps control blood pressure , they can help reduce the risk of stroke.A medium apple provides five grams of fibre-more than most cereals. They’re also packed with pectin, a soluble fibre that reduces cholesterol. Pectin prevents cholesterol from building up in the lining of blood vessel walls, thus reducing the risk of atherosclerosis and heart disease.
