Nutritional qualities and Benefits

One serving of soursop pulp (about 225 grams) contains only 149 calories. The fruit is very low in saturated fat and low in sodium; and has absolutely no cholesterol. It is high in dietary fiber, potassium and Vitamin B, and very high in Vitamin C.

The benefits of Vitamin C are well known. It is an antioxidant that works against free radicals and prevents them from damaging our cells. It is vital in the growth and repair of our tissues, healing of wounds, and the maintenance and repair of our cartilage, bones and teeth. As an antioxidant, Vitamin C inhibits the development of diseases such as cancer, heart disease and arthritis and reduces the destructive effects of cigarette smoke, toxic chemicals and pollution on our bodies. Vitamin C protects you, not only from the common cold and complications in the form of respiratory diseases, but also from deficiency in the immune system, cardiovascular disease, and loss of vision. Our bodies do not make or store Vitamin C so it is important that we continue to replenish our body's supply of vitamin C by eating fruits and vegetables every day.

Dietary fiber, which is found in significant amounts in soursop fruit, keeps you regular, prevents free radicals from damaging healthy colon cells, and prevents colon and rectal cancer. Some studies have shown that fiber may help lower your risk of developing heart disease, high blood pressure, diabetes, strokes and obesity. Soursop contains significant amounts of potassium which our bodies need. Low potassium intake is associated with hypertension, heart disease, arthritis, cancer and infertility. Potassium is also necessary for the healthy and normal functioning of our hearts, kidneys, and other organs. By increasing your intake of potassium, you can also help decrease your blood pressure. This was the finding of a study on men who decreased their risk of suffering a stroke by 60 percent through regular potassium supplements. Soursop is also rich in Vitamins B1 (thiamin) that converts blood sugar into energy and B2 which is necessary for growth and keeps your eyes healthy.

Annona muricata has been the subject of scientific study since the 1940s. In the 70s, research showed that active ingredients in the plant killed cancer cells in vitro or test tubes (breast, ovarian, colon, prostate, liver, lung, and pancreatic). Follow up research work is ongoing.
