Apples have many health benefits. They are rich in fiber. Packing in quite a bit of soluble fiber (4 grams per medium apple) for a modest amount of calories (95) makes apples a filling, sweet snack. Fiber is important because it bulks up our stool and tends to make you more “regular.” But fiber has other benefits as well, some of which are very pertinent to low carbohydrate diets, including lowering the impact of sugars and starches on blood glucose. A high fiber diet is associated with lower risk for heart disease, Type 2 diabetes, and diverticular disease.
Apples are also loaded with vitamins, minerals and antioxidants, like quercetin, epicatechin, and procyanidin B2. Apples are also good in tartaric acid that gives tart flavor to them. These compounds help body protect from deleterious effects of free radicals. They also are a good source of immune-boosting vitamin C. In addition, apple fruit is a good source of B-complex vitamins such as riboflavin, thiamin, and pyridoxine (vitamin B-6). Together these vitamins help as co-factors for enzymes in metabolism as well as in various synthetic functions inside the body. Apple also contains small amount of minerals like potassium, phosphorus, and calcium. Potassium is an important component of cell and body fluids helps controlling heart rate and blood pressure; thus counters the bad influences of sodium.
