The content of dietary fiber in soursop reached 3.3 g per 100 g of fruit flesh. Consumption of 100 g of meat soursop fruit can meet 13 percent of the daily fiber requirement. Vitamins are the most dominant in soursop fruit is vitamin C, which is around 20 mg per 100 grams of fruit flesh. Requirement of vitamin C per person per day (ie 60 mg) can be met only by consuming 300 grams of meat soursop fruit. Fiber is very good to help digestion and detoxification, while vitamin C is an antioxidant that is very good for boosting the immune system and slow the aging process (stay young). Soursop fruit contains very little fat (0.3 g/100 g), so it is good for health. Soursop also contains phosphorus and calcium, respectively 27 and 14 mg per 100 g. Both minerals are important for the formation of bone mass that allows you to build strong bones and prevent osteoporosis. Soursop excellence lies in the content of sodium (sodium) is low (14 mg per 100 g), but high in potassium (potash), which is 278 mg per 100 g.

2.5- The Uses of Soursop Fruits on the World + Culinary Uses of Soursop Fruit Due to the fruit’s widespread cultivation and popularity in parts of Latin America, the Caribbean, Africa, Southeast Asia and the Pacific, soursop and its derivative products are consumed across the world, also via branded food and beverage products available in many countries, including Brazil, Mexico, Canada, the United States, the UK, Ireland and Continental Europe, Indonesia, Japan, Malaysia, Singapore and Vietnam.

Some of the traditional treatments include: Soursop fruit seeds are used to treat vomiting. Soursop leaves are made into a poultice and used for treating skin disorders. Soursop fruit pulp is applied directly on wounds to help speed up healing. Soursop root bark is used to treat poisoning. A leaf tea or decoction applied topically is used to get rid of head lice and bed bugs. Although controversial, many people claim soursop may be an effective treatment for cancer. While there is as yet no scientific evidence to back up these claims, it is interesting to note that they are traditional remedies that have been used for centuries. The leaves, fruit, seeds, and stem are used to make medicine. Ripe fruit of Soursop contains many chemicals that may be active against disease-causing agents such as bacteria, viruses, and parasites as well as active against cancer! Despite safety concerns, the ripe fruits of Soursop is used to treat infections caused by bacteria and parasites including leishmaniasis, a disease caused by parasites transmitted through the bite of sand fleas; herpes ; coughs ; and cancer . It is also used to cause vomiting and to empty the bowels. Some people use graviola to help them relax. Soursop is applied to the skin for arthritis. Research Since 1976, Soursop or Graviola has proven to be an immensely potent cancer killer in 20 independent laboratory tests, yet no double-blind clinical trials-the typical benchmark mainstream doctors and journals use to judge a treatment’s value-were ever initiated… A study published in the Journal of Natural Products, following a recent study conducted at Catholic University of South Korea stated that one chemical in Soursop was found to selectively kill colon cancer cells at “10,000 times the potency of (the commonly used chemotherapy drug) Adriamycin…” … The most significant part of the Catholic University of South Korea report is that Soursop was shown to selectively target the cancer cells, leaving healthy cells untouched. Unlike chemotherapy, which indiscriminately targets all actively reproducing cells (such as stomach and hair cells), causing the often devastating side effects of nausea and hair loss in cancer patients… A study at Purdue University recently found that leaves from the Graviola tree killed cancer cells among six human cell lines and were especially effective against prostate, pancreatic and lung cancers… Laboratory research supports the potential benefits of soursop as a remedy for disease. In one study, published in "Journal of Ethnopharmacology," an extract of soursop inhibited the growth of Herpes virus in the laboratory. In addition, the Cancer Center summarizes findings that suggest soursop extracts might slow growth of cancer cells or make them more susceptible to anti-cancer drugs. For example, in one study published in 1997 in "Journal of Medicinal Chemistry," compounds from soursop were tested on breast cancer cells in culture and found to be up to 250 times more effective in killing the cells than some chemotherapy drugs. These laboratory studies with soursop are promising, but research with human subjects is needed to confirm its potential usefulness. Note about Alternative cancer treatment The Memorial Sloan-Kettering Cancer Center lists cancer treatment as one of the "purported uses" of soursop. According to Cancer Research UK, "Many sites on the internet advertise and promote graviola capsules as a cancer cure, but none of them are supported by any reputable scientific cancer organisations" and "there is no evidence to show that graviola works as a cure for cancer" and consequently they do not support its use as a treatment for cancer. In 2008 a court case relating to the sale in the UK of Triamazon, a soursop product, resulted in the criminal conviction of a man under the terms of the UK Cancer Act for offering to treat people for cancer. A spokesman for the council that instigated the action stated, "it is as important now as it ever was that people are protected from those peddling unproven products with spurious claims as to their effects." The Federal Trade Commission in the United States determined that there was "no credible scientific evidence" that the extract of soursop sold by Bioque Technologies "can prevent, cure, or treat cancer of any kind." Recommendations The recommended intake of soursop fruit or its extract has not been established. However, one fruit contains about 15 milligrams of annonacin, its most studied component, and one can of commercially prepared soursop nectar provides 36 milligrams. Avoid consuming soursop in excess, however, since large quantities of its alkaloid compounds may cause neurological symptoms similar to Parkinson's disease. Do not self-treat with soursop or its extract. Discuss its use with your doctor to decide what is best for your situation.
