According to the network meta- analysis the Mediterranean diet is the most effective and efficacious dietary approach to improve glycaemic control in type 2 diabetes patients
The aim of the present study is to assess the comparative efficacy of different dietary approaches on glycaemic control in patients with type 2 diabetes mellitus using a systematic review of the literature .
Olive leaf extract as a hypoglycemic agent in both human diabetic subjects and in rats.
Olive tree ( Olea europaea L. ) leaves have been widely used in traditional remedies in European and Mediterranean countries as extracts , herbal teas , and powder . They contain several potentially bioactive compounds that may have hypoglycemic properties . To examine the efficacy of 500 mg oral olive leaf extract taken once daily in tablet form versus matching placebo in improving glucose homeostasis in adults with type 2 diabetes ( T2DM ) . In this controlled clinical trial , 79 adults with T2DM were r and omized to treatment with 500 mg olive leaf extract tablet taken orally once daily or matching placebo . The study duration was 14 weeks . Measures of glucose homeostasis including Hba1c and plasma insulin were measured and compared by treatment assignment . In a series of animal models , normal , streptozotocin ( STZ ) diabetic , and s and rats were used in the inverted sac model to determine the mechanism through which olive leaf extract affected starch digestion and absorption . In the r and omized clinical trial , the subjects treated with olive leaf extract exhibited significantly lower HbA1c and fasting plasma insulin levels ; however , postpr and ial plasma insulin levels did not differ significantly by treatment group . In the animal models , normal and STZ diabetic rats exhibited significantly reduced starch digestion and absorption after treatment with olive leaf extract compared with intestine without olive leaf treatment . Reduced digestion and absorption was observed in both the mucosal and serosal sides of the intestine . Though reduced , the decline in starch digestion and absorption did not reach statistical significance in the s and rats . Olive leaf extract is associated with improved glucose homeostasis in humans . Animal models indicate that this may be facilitated through the reduction of starch digestion and absorption .  Olive leaf extract may represent an effective adjunct therapy that normalizes glucose homeostasis in individuals with diabetes
