Eggplant is a tasty and healthy vegetable that is also a great way to get more fiber into your diet. Let's find out if eggplants are good for diabetes.

Glycemic Index and Carbohydrates

The recommended diet for type 2 diabetes is a low carbohydrate and low glycemic index diet.

Eggplants are considered low glycemic index foods. The GI of eggplant is 30. Therefore the carb content of eggplant is also low: 5.88g per 100g, of which 3g is fiber.

This means that eggplant does not affect blood sugar levels. Moreover, they can help to keep your blood sugar in check.

According to research, the fiber in eggplant may help lower blood glucose levels and improve blood sugar and insulin levels (1).

Type-2 Diabetes

Diets containing eggplant are recommended by the American Diabetes Association and the National Diabetes Education Program of the National Institutes of Health for type 2 diabetics. Eggplant is also high in phenols, which have antioxidant properties that help people with diabetes control their blood sugar levels. According to research, phenols may regulate the body's carbohydrate metabolism. This allows insulin more time to break down the carbohydrates, which are primarily from refined foods with little fiber or vitamin content (2).

Another study shows that polyphenols can help reduce sugar absorption and increase insulin secretion, which can help lower blood sugar. Eating eggplants inhibits the enzyme that converts starch into blood sugar, making it one of the most effective foods for preventing diabetic issues (2).

In addition, because eggplant may inhibit α-amylase activity, it may help regulate postprandial hyperglycemia and lower the risk of developing diabetes (3.4).

In summary, eggplants are a great source of fiber and polyphenols, which may help reduce blood sugar levels.
