Effects of Brazil Nut Consumption and Middle-Intensity Aerobic Training for 6 Weeks on Blood Lipid Profiles and Atherogenic Index in White Rats

The purpose of this study was to investigate the effect of Brazil nut and middle-intensity aerobic exercise on blood lipid profiles and atherogenic index in white rats. The participants were divided into three groups: 1) the normal diet+non-exercise group(n=17); 2) the Brazil nut containing diet+non exercise group(n=20); 3) the Brazil nut containing diet+aerobic exercise group(n=18).<br/>One-way ANOVA was conducted to analyze blood lipid profiles and atherogenic index among groups.<br/>The results were as follows:<br/>HDL-C, LDL-C, TG, and TG/HDL-C was statistically significantly higher in the Brazil nut containing diet+non exercise group than in the normal diet+non-exercise. Also, in the Brazil nut containing diet+aerobic exercise group than in the Brazil nut containing diet+non exercise group. But in TC, there was no statistically significant difference among groups.<br/>For such a reason, Brazil nut consumption and middle-intency aerobic exercise program may be a safe and effective strategy for the prevention of cardiovascular disease.
