effectiveness of shelled almonds in decreasing blood lipid and lipoprotein levels of hyperlipidemic patients

introduction: hyperlipidemia is a risk factor for atherosclerosis and cardiovascular diseases. nuts such as almonds are high in unsaturated lipids and antioxidants. some studies indicate that nuts have beneficial effects on cardiovascular system. therefore, the aim of this study was evaluation of the effectiveness of shelled almonds on reduction of blood lipid and lipoprotein levels in hyperlipidemic patients. methods: this study was a clinical trial (before and after) and was done on 30 men volunteering for the study. they consumed 60 grams shelled almonds per day for four weeks. their blood lipid, lipoprotein, apolipoprotein and lipoprotein (a) levels were measured after and before almond consumption. results: shelled almond consumption caused significant decrease in serum cholesterol 36.1 mg/dl, triglyceride 45.94 mg/dl, ldl-cholesterol 28.68 mg/dl and increase in hdl-cholesterol 10.64 mg/dl(p<0.001). shelled almond consumption decreased lipoprotein (a) (2.11 mg/dl), apolipoprotein b100 (8.93 mg/dl) and increased apolipoprotein a (1 1.74 mg/dl) levels, but this effect was insignificant statistically. conclusion: continuous consumption of shelled almonds has beneficial effect on blood lipids and may play a preventive role in atherosclerosis and coronary heart diseases. we therefore suggest that a daily intake of 60 grams of almonds can be used for treatment of hyprelipidemic patients.
