Broccoli
Sulforaphane is a plant chemical with blood sugar-reducing properties produced when broccoli is chewed or chopped. Broccoli extract is rich in sulforaphane and has been shown to possess potent antidiabetic effects in several animal, test-tube, and human studies. These properties help enhance insulin sensitivity and reduce oxidative stress markers. Broccoli sprouts are rich in glucosinolate, compounds that also help promote sensitivity to insulin and reduce blood sugar levels in individuals diagnosed with type 2 diabetes.
