Soursop Nutrition Facts and Health Benefits

Soursop is a member of the custard apple family and comes from the Annona muricata broadleaf evergreen, known for its health benefits including reducing inflammation, improving the immune system, and easing digestive symptoms. Read more soursop benefits below.

What is Soursop?

The unusually shaped soursop fruit—it looks like an oversized strawberry crossbred with an apple with thorns—is native to Central and South America and is a popular, sweet delicacy there. Soursop tastes like a combination of strawberries, pineapple, and citrus.

Soursop Nutrition Facts

One cup of soursop pulp (225g) provides 148 calories, 2.3g of protein, 37.8g of carbohydrates, and 0.7g of fat. Soursop is an excellent source of vitamin C, fiber, and potassium. The following soursop nutrition information is provided by the USDA.1

Carbs

Soursop contains almost 38 grams of carbohydrates per cup. The carbs in soursop are from naturally occurring sugars and contain more than 7 grams of fiber per serving (about a quarter of your recommended daily intake). The glycemic index of soursop is low.2

Fats

Soursop is low in fat, providing less than one gram per serving.

Protein

Soursop, like most fruits, is not a good source of protein. A single serving contains only 2.3 grams of protein. So you'll need to incorporate other protein sources, such as salmon, lean meats, and legumes, into your diet to meet your daily needs.

Vitamins and Minerals

Soursop comes packed with micronutrients. One cup provides 46.4 mg of vitamin C. The USDA recommends an intake of 90 mg daily to support your immune system. Soursop also provides 626 mg of potassium for blood pressure regulation and rapid workout recovery.

Soursop Benefits

Soursop, also known as graviola or guanabana, may also provide a range of other health benefits. For example, graviola tea—made from the leaves (not the fruit) of the soursop plant—is often used to treat infections (both bacterial and viral) that cause cold-like symptoms. In addition, some people use it to treat sexually transmitted diseases like herpes.

Not enough scientific evidence supports these uses, although studies show that some soursop extracts may provide immune system support.3

Potential for Cancer Prevention

One study reported that extracts from soursop fruit and the tree's bark, roots, and leaves had the therapeutic potential to combat cancer and other non-malignant diseases.4

However, not enough human data support this claim. Experts from Cancer Treatment Centers of America warn against using soursop as a cancer fighter, and they note that soursop is associated with numerous unsubstantiated claims.5 Drugs developed from compounds in the soursop plant are more likely to be effective than simply consuming the fruit or tea made from its leaves.6

Promotes Digestive Health

Due to its high fiber content, soursop may aid with proper digestion. The fruit’s juice can also act as a diuretic and cleanse the gastrointestinal tract by removing excess sodium from the body. An extract of soursop has been shown to help heal gastric ulcers in lab animals.7

Fights Inflammation

Like most fruits and vegetables, soursop is a good source of antioxidants, which might help the body repair cell damage and combat inflammation.8

Allergies

There are no cases of soursop allergies reported in medical literature. But any food that contains protein can theoretically be allergenic. If you experience food allergy symptoms (such as itching, swelling, or hives), consult a physician for diagnosis.

Adverse Effects

You should avoid consuming soursop or drinking the fruit in a tea if any of the following apply to you:

• You have diabetes, as graviola has blood sugar-lowering effect in laboratory animals.
• You are taking drugs to reduce hypertension, as graviola is shown to have additive effects when taken with drugs for this health issue.9
• You have liver disease.
• You have kidney disease.10

Studies in laboratory animals have shown that compounds in graviola cause movement disorders and myeloneuropathy, a disease with symptoms similar to Parkinson’s Disease.9 

Varieties of Soursop

In some regions, both "sweet" (less acidic) and "sour" soursop are cultivated. The sweet version is more likely to be eaten raw.

Soursop tea is brewed from the leaves of the soursop tree. It has traditionally been used to relax the body and decrease stress.

When Soursop Is Best

This tropical fruit is mostly available in Central and South America. However, some grocery stores carry frozen soursop.

You can substitute soursop with cherimoya, a popular alternative available online and in some groceries. Cherimoya tastes similar to soursop, as it comes from the custard apple family and offers comparable nutritional value. However, cherimoya does not have the cancer-fighting potential of soursop or the same anti-inflammatory properties.

If you cannot find cherimoya or soursop, you can create soursop's flavor profile by blending equal parts of strawberries, pineapple, and bananas.

Storage and Food Safety

You can store unripe, whole soursop fruits at room temperature. Ripened fruits will keep for a couple of days in the refrigerator.

How to Prepare

Because the fruit is local to the tropics, you will not find soursop in abundance in North America. If you get your hands on the fruit, you can eat it like any raw fruit. You can also incorporate soursop into syrups, smoothies, and other desserts such as ice creams, candies, and sweet beverages.
