There was no effect on waist circumference , high-density lipoprotein cholesterol or blood pressure with the direction of effect favouring tree nuts for waist circumference .
Pooled analyses show a MetS benefit of tree nuts through modest decreases in triglycerides and fasting blood glucose with no adverse effects on other criteria across nut types .
OBJECTIVE To provide a broader evidence summary to inform dietary guidelines of the effect of tree nuts on criteria of the metabolic syndrome ( MetS ) .
Effects of hazelnuts consumption on fasting blood sugar and lipoproteins in patients with type 2 diabetes
Background : Previous studies have demonstrated that nuts consumption have beneficial effects on serum lipid profiles in hyperlipidemic or normolipidemic subjects . However , similar studies in diabetes field are quite rare . So , we aim ed to investigate the effects of hazelnut consumption on fasting blood sugar ( FBS ) and lipid profiles in patients with type 2 Diabetes . Material s and Methods : An 8-week controlled r and omized parallel study in patients with type 2 diabetes . Fifty eligible volunteers were assigned to either the control or intervention groups . 10 % of total daily calorie intake was replaced with hazelnuts in intervention group . Blood sample s were collected from fasting patients at the start and at the end of the study . Results : After 8 weeks , there were significant differences in high-density lipoprotein-cholesterol ( HDL-C ) concentrations between two groups , using analyses of covariance ( P = 0.009 ) , which was due to the larger HDL-C reduction in control group ( P = 0.003 ) . Although , Hazelnut group achieved greater reduction in triglyceride ( TG ) concentrations than control group , these changes were not statistically significant . Neither between-group changes nor within-group changes were significant for FBS , total cholesterol ( TC ) , TG , and low-density lipoprotein-cholesterol ( LDL-C ) levels . Conclusion : Results of this study indicated that incorporation of hazelnuts into diet can prevent reduction of HDL-C concentrations in patients with type 2 diabetes , but had no effect on FBS or other lipid profile indices
