Exploring the Benefits of Custard Apple for Diabetes Management


Custard apple, also known as sugar apple or sweetsop, is a tropical fruit enjoyed for its creamy texture and sweet taste. But did you know that custard apple has potential benefits for managing diabetes? 

In this blog, we will explore the science behind custard apple and it’s impact on blood sugar levels.

Custard Apples for Diabetes – What Does Science Say?

Several studies have shown that consuming custard apples can have a positive effect on blood sugar control in people with diabetes. One study found that eating custard apples led to a significant decrease in fasting blood sugar levels in participants with type 2 diabetes. 

Another study found that custard apple extract had a hypoglycemic (blood sugar-lowering) effect in rats with diabetes.

Custard apples are also a good source of dietary fiber, which can help regulate blood sugar levels by slowing down the absorption of carbohydrates in the digestive system.

Overall, while more research is needed, custard apples may be a beneficial addition to the diet of people with diabetes due to their low GI and potential blood sugar-lowering effects. However, it is important to consult with a healthcare provider before making any significant changes to your diet, especially if you have diabetes.

Glycemic Index of Custard Apple

Custard apples have a relatively low glycemic index (GI), which is a measure of how quickly carbohydrates in food raise blood sugar levels. A low GI indicates that the carbohydrates are digested and absorbed slowly, resulting in a gradual and steady increase in blood sugar levels.

Benefits of Custard Apples for Diabetic Patients

Here are some benefits of custard apples for diabetic patients:

  1. Low glycemic index: 

Custard apples have a low glycemic index, which means they do not cause a rapid rise in blood sugar levels, making them a suitable fruit for people with diabetes.

  1. Regulate blood sugar levels: 

Custard apples contain dietary fiber, which slows down the absorption of carbohydrates in the body and regulates blood sugar levels. This can help diabetic patients control their blood sugar levels.

  1. Rich in antioxidants: 

Custard apples are rich in antioxidants, such as vitamin C, which can help reduce oxidative stress and inflammation, both of which are associated with diabetes.

  1. Improve digestion: 

Custard apples are also rich in dietary fiber, which can improve digestion and prevent constipation, a common problem for people with diabetes.

  1. Boost immunity: 

The high vitamin C content in custard apples can also help boost immunity, which is important for people with diabetes who may have a weakened immune system.

  1. Low in calories: 

Custard apples are low in calories and high in fiber, making them a healthy snack option for people with diabetes who are trying to manage their weight.

  1. Help manage cholesterol levels: 

Custard apples contain soluble fiber, which can help reduce cholesterol levels in the blood, lowering the risk of heart disease, which is a common complication of diabetes.

Overall, custard apples can be a healthy addition to a diabetic patient’s diet due to their low glycemic index, fiber content, and other health benefits. However, it is important to consume custard apples in moderation as they are still a source of natural sugars.

Ways to Include Custard Apple in a Diabetes-friendly Diet 

Here are some ways to include custard apple in a diabetes-friendly diet:

  1. Eat it fresh: Enjoy custard apple as a fresh and healthy snack. Simply cut it open and scoop out the pulp with a spoon. Remember to consume it in moderation to avoid excess sugar intake.
  2. Add it to salads: Add custard apple to your salads to make them more interesting. You can also mix it with other fruits like strawberries or blueberries to make a diabetes-friendly fruit salad.
  3. Make smoothies or shakes: Blend custard apple with low-fat milk or yogurt to make a diabetes-friendly smoothie or shake. You can also add a dash of cinnamon or nutmeg for added flavor.
  4. Use it as a topping: Use custard apple pulp as a topping for oatmeal or yogurt to add natural sweetness to your breakfast.
  5. Use custard apple leaves: According to Ayurveda, custard apple leaves may also help in controlling blood sugar levels. You can boil the leaves in water and drink the decoction regularly to help regulate blood sugar levels.
