The graviola fruit, or soursop, is a tasty fruit that’s popular for its refreshing flavor and impressive health benefits. It offers a lot of fiber and vitamin C with few calories and has gained popularity as a remedy for various viruses. Some believe that it aids with pain relief and may even prevent certain types of cancer. Does the research back the hype? Continue reading to find out.
What Is Soursop?
It is a fruit with a prickly green exterior and bright white flesh that has a creamy texture. Many compare the vibrant flavor to pineapple or strawberry. Typically eaten raw, soursop contains large black seeds that you must avoid. The fruits can be quite large, so it’s best to divide a single fruit into several portions. A typical 100-gram (g) serving of raw soursop exhibits the following nutritional profile:
- Calories: 66
- Carbohydrates: 16.8 g
- Protein: 1 g
- Fiber: 3.3 g
- Vitamin C: 34% of the recommended daily intake (RDI)
- Magnesium: 5% of the RDI
- Thiamine: 5% of the RDI
- Potassium: 8% of the RDI
In addition to the above nutritional profile, soursop also contains small amounts of niacin, folate, iron, and riboflavin. Many parts of the fruit, including the leaves, stems, and fruit, have been used for their medicinal properties. Some animal and test-tube studies found that it may reduce inflammation and slow the growth of certain cancers.
Anti-Inflammatory Activity
A 2010 rodent study found that soursop was able to block pain receptors and reduced inflammation in rats. A 2014 rodent study noted that soup soursop’s anti-inflammatory properties may be useful in relieving pain. Although research is currently limited to animal studies, these findings may open the door for future treatment in humans. In fact, one study found that soursop helped lower inflammatory markers associated with arthritis.
Helps Fight Bacteria
In one test-tube study, soursop extract worked to fight off the bacteria responsible for staph and cholera infections. Another test-test-tube study used soursop extracts of varying concentrations on different types of bacteria responsible for oral diseases. According to the results, soursop effectively killed off multiple types of bacteria, including the strains that cause gingivitis and tooth decay.
May Regulate Blood Sugar
One study, which included diabetic rats, received soursop extract injections for two weeks. The rats that received the injections had blood sugar levels five times lower than the untreated groups. In another study involving diabetic rats that received soursop extract injections, the results indicated a near 75% reduction in blood sugar. Although more research is necessary in humans, these findings in animal studies suggest that soursop may benefit people with diabetes. However, those people must also pair soursop consumption with a healthy diet and active lifestyle.
May Help Kill Cancer Cells
Although this is an exciting claim, it’s worth noting that most research is currently limited to test-tube studies. For example, one test-tube study used soursop extract to treat breast cancer cells. The extract was able to reduce tumor size, enhance immune activity, and kill off cancer cells. Another test-tube study examined soursop extract’s effects on leukemia cells. The results indicated that soursop extract stopped the growth and formation of leukemia cells.
Antioxidants Galore!
Most of soursop’s health benefits stem from the fruit’s inherent antioxidant compounds. Antioxidants work to neutralize free radicals, which if left unchecked can contribute to oxidative stress. According to several studies, antioxidants may play a role in reducing the risk of heart disease, cancer, diabetes, and other health conditions. One test-tube study measured soursop’s antioxidants and showed how they prevented damage to human cells. Soursop also contains plant compounds, including luteolin, tangeretin, and quercetin, all of which are beneficial to humans.
May Lower Blood Pressure
Historically, different cultures used soursop as a folk remedy to lower blood pressure levels. If your blood pressure is unmanaged, your risk of heart disease and stroke is heightened. A 2012 animal study used soursop on rats with high blood pressure and found that it helped lower blood pressure. Researchers noted that soursop exhibited hypotensive abilities due to its effect on calcium ions.
