ANC is an anthocyanin-rich formulation from MB which im- proves hyperglycaemia and insulin resistance in obese hypergly- caemic mice fed a high fat diet. ANC seems to function by modulating glucose metabolism in the skeletal muscle and liver. To our knowledge, this is the first report describing the anti-dia- betic properties and potential mode of action of MB anthocyanins. One of MB’s distinctive anthocyanins, D3S5G, displays insulin-like effects in muscle and liver cells and seems to be partially responsi- ble for the anti-diabetic effect of ANC. As MB’s anthocyanins are regularly consumed as fresh fruits or juice concentrates, we pro- pose ANC as a novel natural source of potentially safe anti-diabetic compounds. Further investigations into the effects of ANC on the glucose metabolism of type II diabetes patients will need to be
completed for the most effective use of ANC for the treatment and prevention of the disease.
