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 .
Walnut Consumption in Hyperlipidemic Patients
Walnut ( Juglans regia L. ) is described as an anticancer , tonic , blood purifier , and detoxifier agent . It is said that nuts have favorable fatty acids and nutrients . This study was performed to determine the lipid-lowering properties of walnut in a population in Shiraz , Southern Iran . In a r and omized case-control study , 52 volunteers were divided into 2 groups : Group A consumed walnuts , 20 grams per day for 8 weeks and the control group ( group B ) consumed no walnuts .  Triglycerides , total high-density lipoprotein ( HDL ) , and low-density lipoprotein ( LDL ) levels were checked for each subject prior to , after 4 weeks , and at 8 weeks after the beginning of the study . In group A , the mean plasma TG level dropped by 17.1 % from the baseline and HDL cholesterol also increased significantly by 9 % . It was shown that frequent consumption of nuts in the daily diet was associated with a potentially decreased risk of coronary artery disease by decreasing the level of triglyceride and increasing the level of HDL
