A recent review of clinical studies done in diabetic and healthy individuals found that legumes and Soybeans lowered blood sugar and hemoglobin A1C (which reflects long-term sugar balance).
Also, soybean consumption has been associated with decreased risk of type 2 diabetes, as opposed to red meat consumption-which, in fact, increases the risk of diabetes.
Soybeans, for instance, can slow digestion and the release of sugars (found in starch) into the bloodstream, which ultimately reduces blood glucose levels.
The slower absorption means you won’t experience a glucose spike, but rather a balanced blood sugar level.
