1. Rich in catechin
Matcha is a rich source of catechin, a compound with strong antioxidant activity. According to research published in Molecles in 2020, epigallocatechin gallate (EGCG) and epicatechin are the main compounds in the catechin group found in matcha. Research in Nutrients in 2022 also shows that catechin can help control diabetes by improving insulin resistance, reducing oxidative stress and having anti-inflammatory effects.
2. Support blood sugar control
"matcha tea can help control diabetes thanks to its ability to increase insulin sensitivity by reducing inflammation - one of the causes of insulin resistance," said Dr. Batra. Polyphenols in matcha also have the effect of improving insulin sensitivity and reducing blood sugar levels. This was confirmed in a study published in the journal Human Nutrition & Metabolism in February 2025.
3. Reduces oxidative stress
oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body, causing cell damage. "The powdery form of green tea can reduce oxidative stress - an important factor in the progression of diabetes and related complications," says Dr. Batra.
Matcha tea is rich in antioxidants, which help neutralize harmful free radicals, thereby preventing complications related to diabetes such as kidney disease, heart disease and eye damage. In addition, matcha also helps reduce cholesterol. "It helps reduce bad cholesterol (LDL) and increase good cholesterol (HDL), thereby reducing the risk of heart disease in people with diabetes," the expert shared.
4. Support weight control
Weight control plays an important role in maintaining stable blood sugar levels and reducing the risk of diabetes complications. If you want to lose weight, consider drinking matcha tea. "This tea can help control weight, thereby helping to control diabetes more effectively. If you are overweight, losing weight will help improve insulin function and control blood sugar more easily," Dr. Batra recommends.
Matcha boosts metabolism and burns fat, helping to lose weight naturally.
Note: Although matcha is beneficial in controlling blood sugar, you should still consume it in moderation. Drinking too much can cause hypoglycemia and nausea. Before using matcha regularly, consult your doctor, especially if you are taking diabetes medication. In addition, matcha tea should be combined with a balanced diet and regular physical exercise to achieve the best diabetes control results.
