Jamun juice has several health benefits, and experts believe blood sugar management is one of them. Here’s what makes it so special.

According to , pure jamun juice contains bioactive compounds, like jamboline and ellagic acid, which naturally slow down sugar absorption in the body. "The important constituents present in the black jamun are anthocyanins and polyphenolic compounds (glucoside, anthocyanin, ellagic acid, isoquercetin, jambolin and jambosine), which have been reported to reduce blood glucose. However, among these, jambolin and jambosine appreciably alter the hydrolysis of carbohydrates into the simpler sugars and thereby improve the diabetic condition," he explains, adding that these compounds aid in maintaining steady glucose levels, giving those with high blood sugar a smoother, healthier way to manage it. Plus, it encourages insulin sensitivity, making it a diabetes-friendly fruit.

A 2022 study published in the journal suggests that jamun can be used to treat metabolic syndrome-related symptoms all over the world. Researchers shared that jamun's seeds, also known as “Maghz-e-Jamun or Tukhm-e-Jamun”, have an antihyperlipidemic action in intermediate hyperglycaemia (prediabetes). Antihyperlipidemic action refers to the effect of drugs or other substances in lowering abnormally high levels of lipids (fats), such as cholesterol and triglycerides, in the blood.

Additionally, the fruit supports the conversion of carbohydrates to energy and regulates blood sugar levels. Moreover, it is low on the glycaemic index, which makes it a great addition for a diabetic diet.

Dr Reddy recommends having 0.5 – 2 tsp (2.5 – 10 ml) of ripe jamun fruit juice thrice a day.

As far as fruit itself is concerned, you can have a moderate amount of 8-10 fruits a day.

The following are some jamun fruit side effects that people should note:

• Constipation: Overeating may slow down digestion.
• Not safe before surgery: Jamun may affect blood sugar levels, so it's advised not to eat it before or after surgery.

Dr Reddy adds, “Jamun has the potential to reduce blood sugar levels. Therefore, when taking Jamun in addition to antidiabetic medications, it is generally advised to keep an eye on your blood sugar levels.”

Jamun is known for its rich nutritional profile, which is why it is often considered a superfood. Packed with several vitamins, minerals, and antioxidants, it has been traditionally used for medicinal properties, particularly in the treatment of high blood sugar in diabetic patients. However, one should remember to consume it in moderation – be it raw or as juice. Speak to a doctor if you are already on diabetic medication.
