In order to study the effect of anthocyanins on the improvement of glucose and lipid metabolism, randomized intervention trials were conducted to compare the effects of anthocyanins on the improvement of glucose and lipid metabolism in different dose groups.To explore the best dose of anthocyanins for the prevention and treatment of anthocyanin metabolic diseases provide an important scientific basis.
In order to study the effect of anthocyanins on the improvement of glucose and lipid metabolism, randomized controlled trials were conducted to enrolled 300 patients with dyslipidemia. The subjects were divided into 0 mg / d, 40 mg / d, 80 mg / d, 320 mg/ d five dose groups, intervention for 12 weeks, comparing different doses of anthocyanins on glucose and lipid metabolism.To explore the best dose of anthocyanins for the prevention and treatment of anthocyanin metabolic diseases provide an important scientific basis.
