Significant heterogeneity was not observed by nut type or other factors .
Tree nut intake  lowers total cholesterol , LDL cholesterol , ApoB , and triglycerides .
The major determinant of cholesterol lowering appears to be nut dose rather than nut type .
BACKGROUND The effects of nuts on major cardiovascular disease ( CVD ) risk factors , including dose-responses and potential heterogeneity by nut type or phytosterol content , are not well established .
OBJECTIVES We examined the effects of tree nuts ( walnuts , pistachios , macadamia nuts , pecans , cashews , almonds , hazelnuts , and Brazil nuts ) on blood lipids [ total cholesterol , low-density lipoprotein ( LDL ) cholesterol , high-density lipoprotein , and triglycerides ] , lipoproteins [ apolipoprotein A1 , apolipoprotein B ( ApoB ) , and apolipoprotein B100 ] , blood pressure , and inflammation ( C-reactive protein ) in adults aged ≥18 y without prevalent CVD .
Pistachio diet improves erectile function parameters and serum lipid profiles in patients with erectile dysfunction
We investigated the effects of Antep pistachio on International Index of Erectile Function ( IIEF ) scores , penile color Doppler ultrasound ( PCDU ) parameters and serum lipid levels in patients with ED . A total of 17 married male patients with ED for at least 12 months were included in this prospect i ve study . Patients were put on a 100 g pistachio nuts diet for 3 weeks .  IIEF and PCDU were evaluated before and after the pistachio diet . In addition , plasma total cholesterol ( TC ) , low-density lipoprotein ( LDL ) , high-density lipoprotein ( HDL ) and triglyceride  were measured before and after dietary modifications from all subjects . Mean IIEF-15 score was 36±7.5 before the diet and 54.2±4.9 after the diet ( P=0.001 ) . Similarly , an increase in all five domains of IIEF was observed after the diet ( P<0.05 ) . Mean peak systolic velocity values before and after the pistachio diet were 35.5±15.2 and 43.3±12.4 cm s–1 , respectively ( P=0.018 ) . After the pistachio diet , TC and LDL levels decreased significantly , whereas HDL level increased ( P=0.008 , 0.007 and 0.001 , respectively ) . We demonstrated that a pistachio diet improved IIEF scores and PCDU parameters without any associated side effects in patients with ED . Furthermore , the lipid parameters showed statistically significant improvements after this diet
