Is it acceptable for people with diabetes to drink soy milk while eating?
Generally, individuals with diabetes can consume an appropriate amount of soy milk during meals. The rationale is as follows:

Soy milk is rich in protein and dietary fiber—essential nutrients for the human body. Since people with diabetes must restrict their intake of staple foods—particularly carbohydrates—they need to ensure adequate intake of other energy-providing nutrients, such as protein. Soy milk contains abundant high-quality plant-based protein, which helps meet the nutritional needs of individuals with diabetes. Therefore, moderate consumption of soy milk during meals is acceptable for diabetic patients; however, long-term excessive intake should be avoided to prevent potential adverse effects.
Although soy milk offers benefits for people with diabetes, it must still be consumed in moderation. Prolonged, excessive consumption may lead to certain adverse effects in diabetic individuals, including gastrointestinal discomfort, malnutrition, and weight gain. Thus, diabetic patients are advised to control their soy milk intake and avoid overconsumption.
In daily life, individuals with diabetes should follow a light, low-calorie diet and avoid high-calorie foods to help maintain stable blood glucose levels.
