No significant treatment effects were observed for fasting insulin and HOMA-IR , however the direction of effect favoured tree nuts .
Pooled analyses show that tree nuts improve glycemic control in individuals with type 2 diabetes , supporting their inclusion in a healthy diet .
BACKGROUND Tree nut consumption has been associated with reduced diabetes risk , however , results from r and omized trials on glycemic control have been inconsistent .
OBJECTIVE To provide better evidence for diabetes guidelines development , we conducted a systematic review and meta- analysis of r and omized controlled trials to assess the effects of tree nuts on markers of glycemic control in individuals with diabetes .
A low carbohydrate Mediterranean diet improves cardiovascular risk factors and diabetes control among overweight patients with type 2 diabetes mellitus: a 1-year prospective randomized intervention study.
BACKGROUND The appropriate dietary intervention for overweight persons with type 2 diabetes mellitus ( DM2 ) is unclear . Trials comparing the effectiveness of diets are frequently limited by short follow-up times and high dropout rates . AIM The effects of a low carbohydrate Mediterranean ( LCM ) , a traditional Mediterranean ( TM ) , and the 2003 American Diabetic Association ( ADA ) diet were compared , on health parameters during a 12-month period . METHODS In this 12-month trial , 259 overweight diabetic patients ( mean age 55 years , mean body mass index 31.4 kg/m(2 ) ) were r and omly assigned to one of the three diets . The primary end-points were reduction of fasting plasma glucose , HbA1c and triglyceride ( TG ) levels . RESULTS 194 patients out of 259 ( 74.9 % ) completed follow-up . After 12 months , the mean weight loss for all patients was 8.3 kg : 7.7 kg for ADA , 7.4 kg for TM and 10.1 kg for LCM diets . The reduction in HbA1c was significantly greater in the LCM diet than in the ADA diet ( -2.0 and -1.6 % , respectively , p < 0.022 ) . HDL cholesterol increased ( 0.1 mmol/l + /- 0.02 ) only on the LCM ( p < 0.002 ) . The reduction in serum TG was greater in the LCM ( -1.3 mmol/l ) and TM ( -1.5 mmol/l ) than in the ADA ( -0.7 mmol/l ) , p = 0.001 . CONCLUSIONS An intensive 12-month dietary intervention in a community-based setting was effective in improving most modifiable cardiovascular risk factors in all the dietary groups . Only the LCM improved HDL levels and was superior to both the ADA and TM in improving glycaemic control
