Health Benefits
Apple is a rich source of both soluble and insoluble fiber. Soluble fiber like pectin prevents cholesterol accumulation in the lining of the blood vessel walls, hence reducing the risks of atherosclerosis and heart disease. The presence of insoluble fiber in the apple supplies bulk to the intestinal tract, which holds the water and transfers the food quickly through the digestive system. The potassium present in this fruit helps in optimizing the heart functionality and protects the arteries from plaque buildup. It improves the bowel functions and minimizes the risks of Type II diabetes and strokes.

Apple skin contains quercetin, an antioxidant compound that forbids the oxygen molecules from damaging individual cells, preventing cell changes that can cause cancer. Along with this, quercetin inhibits the growth of tumors and prevents cancer cells from spreading. Malic acid and tartaric acid in the apple prevent malfunctioning of the liver and disturbances in digestion. Apple is also beneficial in treating health disorders like anemia, dysentery, headache, eye disorders, and kidney stones. Apple or apple juice is an excellent way of supplying necessary fluids to the body. According to research, eating five apples a week may reduce the risk of certain respiratory diseases like asthma.

Regular consumption of this fruit, not only reduces the ill effects of cholesterol on the body, but also helps in losing weight. Therefore, body builders, athletes, and those on a weight loss diet are advised to eat at least one apple every day. Calories present in an apple promote overall vigor and vitality in our body, which is required for performing daily activities.
