2. Garlic Extract
A 2012 study among rabbits found that the regular use of garlic extract led to a significant reduction in blood glucose levels when compared to the control. Although the study used rabbits, there was still a 30 point reduction in blood glucose levels, which is significant enough to cause substantial positive effects for humans. While garlic is typically known to reduce cholesterol, maybe now it will get even more attention now that type II diabetes is prevalent.
