Can People with Diabetes Drink Red Bean, Euryale Seed, and Coix Seed Tea?
Individuals with diabetes may consume red bean, coix seed, and euryale seed tea—provided their blood glucose levels are well-controlled. Generally, this tea may be consumed in moderation when fasting blood glucose is below 6 mmol/L, postprandial (2-hour) blood glucose is under 8 mmol/L, and HbA1c is less than 7%. Other suitable beverages include oat tea and barley tea. Increasing overall fluid intake—including plain or lightly brewed teas—can aid glycemic control in people with diabetes, enhance satiety, promote metabolism, prevent pre-meal hyperglycemia, and reduce the risk of diabetic ketoacidosis. Adequate hydration also supports weight management in individuals with diabetes. Therefore, if blood glucose is well-controlled per clinical targets, red bean, coix seed, and euryale seed tea may serve as a beneficial adjunct to glycemic and weight management.

The most common traditional benefit attributed to red bean and coix seed tea is its ability to resolve dampness. Combined, these two ingredients help invigorate the Spleen, support healthy gastrointestinal function, and exert tonifying, anti-edematous, and diuretic effects. They are relatively easy to digest and absorb, placing minimal burden on the Spleen and Stomach. According to Traditional Chinese Medicine (TCM), excessive internal dampness may contribute to obesity or edema. When blood circulation stagnates and fails to flow smoothly with Qi and Blood, metabolic waste may accumulate at the cellular level, potentially manifesting as localized swelling or minor wounds; red bean and coix seed tea may thus help alleviate edema and support healthy weight management. Furthermore, modern research indicates that coix seed contains selenium, which has demonstrated inhibitory effects on cancer cell proliferation. Red bean and coix seed tea also offers benefits such as constipation prevention and blood-nourishing properties.

Personal health maintenance is essential. Incorporating appropriate herbal or functional teas into daily routines—especially those with recognized health-promoting properties—can significantly benefit everyday wellness and long-term health. We hope this information is helpful to you!
