A native of the warm and tropical regions of the Americas, soursop is a fruit that goes by many names. Its scientific name is Annona muricata, but it also goes by guanabana, paw-paw, sirsak, and graviola.
Soursop is a member of the Annonaceae family, also known as the custard apple family.
Soursop is high in vitamin C, an antioxidant known to boost immune health. The vitamin strengthens your immune system, improving its ability to defend against pathogens. It also promotes the destruction of free radicals, which can help to protect your skin and cells from environmental oxidative damage. One whole soursop fruit contains 215% of your recommended daily allowance of vitamin C.
Soursop (the fruit and the leaves) contains many other antioxidants, including phytosterols, tannins, and flavonoids. Antioxidants play a role in your overall health and may help to protect against a variety of health conditions.
Other health benefits of soursop include:
One whole soursop fruit contains around 83% of your recommended daily allowance of fiber, which is a vital nutrient for your digestive health. Fiber helps to promote regularity and prevent digestive issues such as constipation.
Potential anti-carcinogenic effects
While most research is limited to test-tube studies, soursop may be beneficial in helping to fight and prevent cancer. One study found that a soursop extract could reduce the size of breast cancer tumors and kill cancer cells. A second study found that an extract could stop the formation of leukemia cells.
Antioxidants fight free radicals, reducing the damage to your cells caused by oxidative stress. One of the side effects of oxidative stress is inflammation. The antioxidants in soursop may, therefore, help to reduce inflammation in the body.
Stabilizes blood pressure
High blood pressure may lead to serious issues like heart disease and heart attack. A contributing factor to high blood pressure is sodium intake. Potassium helps your body to get rid of sodium and eases the tension in the walls of your blood vessels, both of which can help to lower your blood pressure. A whole soursop fruit offers approximately one-third to one-half of your recommended daily allowance of potassium.
May fight against bacteria
Soursop may provide antibacterial effects. One study found that an extract may be able to kill many different types of bacteria, including strains that cause gum disease and cavities. Another study found that soursop extracts may help to fight cholera and Staphylococcus bacteria. While these were test-tube studies, the results are promising, and further research is needed.
