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 .
SERUM LIPID EFFECTS OF A MONOUNSATURATED (PALMITOLEIC) FATTY ACID‐RICH DIET BASED ON MACADAMIA NUTS IN HEALTHY, YOUNG JAPANESE WOMEN
1 . Recent studies have identified potential beneficial effects of eating nuts , most of which have substantial amounts of monounsaturated fatty acids ( MUFA ) .  Macadamia nuts consist of 75 % fat by weight , 80 % of which is MUFA ( palmitoleic acid )
