When eaten raw, soursop has a creamy and juicy texture, similar to a ripe avocado, with a flavor reminiscent of pineapple, strawberry, and citrus fruits. Some people also detect notes of banana, coconut, or vanilla.

Soursop is not typically cooked, as the heat can destroy some of the delicate flavors and nutrients in the fruit. However, it is sometimes used to make drinks, ice creams, and other desserts. When soursop is processed this way, the flavor is usually more intense and sweeter than when eaten raw.

Nutritional Benefits of Soursop

The fiber content in soursops helps to regulate bowel movement, prevent constipation, and improve overall digestive health. Vitamin C is an antioxidant that helps to strengthen the immune system, boost collagen production, and reduce the risk of chronic diseases such as cancer, heart disease, and stroke.

Soursop may have anticancer properties. One study found that the soursop leaf extract can potentially kill cancer cells. However, it’s crucial to establish that this is not considered a cancer treatment but something that can encourage healing alongside regular medical treatment.

Lastly, soursops contain antioxidants such as flavonoids, tannins, and phenolic acids that help to fight inflammation, protect against cellular damage, and prevent chronic diseases. 

Note: Soursop can have some toxicity. Eating in large doses can be harmful and cause symptoms similar to Parkinson’s disease, so proceed cautiously.
