The effects of tiger nut oil-based diet on the lipid profile and activities of cellular enzymes of male rats were investigated. Rats were randomized into two groups and, fed control diet (soya bean oil-based diet) and tiger nut oil-based diet for 21 days. Total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDLc), and very low-density lipoprotein cholesterol (VLDLc) were significantly lowered in the serum of tiger nut oil-based diet-fed rats. Conversely, the high-density lipoprotein cholesterol (HDLc) was significantly increased in the serum of tiger nut oil-based diet-fed rats. The activities of alkaline phosphatase, alanine aminotransferase, and aspartate aminotransferase were not altered. Similarly, superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, and malondialdehyde in the liver, kidney, and heart of tiger nut oil-based diet were not altered. Tiger nut oil-based diet significantly raised GSH. As evident from the lowered serum TC, TG, LDL, and VLDL with concomitant increased HDL, tiger nut oil-based lowers predisposition to cardiovascular risk. Consumption of tiger nut oil, an under-utilized plant food, in diet could lower predisposition to cardiovascular related diseases while improving the concentration of good cholesterol. Tiger nut oil can be used in cooking and frying at home because of its oxidative and thermal stability, and essential fatty acids.
