Generally, diabetic patients can drink soy milk, but they should consume it in moderation.

Soy milk is rich in plant protein, soy isoflavones, vitamin B complex, and other nutrients. These components can help diabetic patients control their blood sugar levels. Soy isoflavones have certain antioxidant properties that may help reduce damage caused by oxidative stress, while dietary fiber can slow down the digestion process and reduce the rate at which blood sugar rises, thus benefiting blood sugar control. Therefore, diabetic patients can drink soy milk in moderation.

However, diabetic patients should choose unsweetened or low-sugar soy milk to avoid additional sugar intake that may cause blood sugar fluctuations. Secondly, diabetic patients with impaired kidney function should moderate their protein intake, including plant proteins such as soy milk, to avoid placing extra strain on the kidneys.

In daily life, diabetic patients should regularly monitor their blood sugar levels, consult with a doctor or nutritionist when adjusting their diet, and develop an individualized dietary plan.
