Blood glucose testing during a physical examination requires fasting, but I drank unsweetened soy milk this morning and I'm wondering if I can still be tested. Does soybean raise blood glucose levels?

Soybeans, as a food rich in high-quality protein, dietary fiber, unsaturated fatty acids, and various vitamins and minerals, indeed have the potential to raise blood sugar levels, but their glycemic index is relatively low.

Soybeans are a nutrient-rich food, containing various nutrients such as plant protein, carbohydrates, fat, sugars, minerals, and vitamins. After consumption, these components can provide energy to the human body, potentially leading to an increase in blood sugar levels. The glycemic index of soybeans generally ranges between 15 and 18, classifying them as a low glycemic index food. This means that after consuming soybeans, blood sugar levels rise relatively slowly, making them a better food choice for individuals needing to control their blood sugar levels, such as diabetic patients.

Due to their low glycemic index characteristic, soybeans are suitable for consumption by individuals with high blood sugar or diabetes, as they can enhance satiety without negatively impacting blood sugar control levels.
