Ginger Lowers blood sugar and increases insulin release. In the case of diabetes, studies have shown ginger to be effective both preventively and therapeutically.
Research at the University of Sydney in Australia found ginger to be effective in glycemic control for people with type 2 diabetes. The study, published in the Planta Medica journal, showed that ginger extracts can increase uptake of glucose into muscle cells without using insulin, therefore it may assist in the management of high blood sugar levels.
Another clinical trial concluded that diabetic patients, that consumed three grams of dry ginger for 30 days, had a significant reduction in blood glucose, triglyceride, and in total and LDL cholesterol levels.
Overall, ginger works on diabetes by increasing insulin release and sensitivity, inhibiting enzymes in carbohydrate metabolism, and improving lipid profiles. Ginger also has a very low glycemic index (GI), which means it breaks down slowly to form glucose, and therefore does not trigger a spike in blood sugar levels like high GI foods do.
Several other studies have also established ginger to have a preventive effect against diabetes complications. Ginger can protect a diabetic’s liver, kidneys, and central nervous system, and reduce the risk of cataracts – a common side-effect of the disease.
