| Dietary fats have been shown to negatively impact bone quality and the effect may be mediated by inhibiting osteoblast and by increasing osteoclast activity as evident from consuming diets high in saturated fat. A retrospective experiment evaluated the effect of canola oil and coconut oil on bone markers in rat. Effect of feeding a low fat (LF; 15%) or high fat (HF; 45%) fat diet on bone quality was determined by evaluating bone density, bone strength, bone concentrations of Ca and magnesium Mg, and antioxidant status in rats. Bone strength was lowered (P < 0.05) by eating a HF. Ca content of the fifth lumbar was negatively affected (P < 0.05) by HF. The results showed that despite similarity in femoral strength, femoral density, femoral ash percentage, and Mg content, rats that consumed coconut oil had higher (P < 0.05) femoral and fifth lumbar Ca content than rats consuming canola oil. Neither coconut oil nor canola oil dietary inclusion affected plasma antioxidant status. Further research is required to consider the deleterious effects of high dietary fat intake on bone quality.;Key words: Canola oil, Coconut oil, Bone quality, Rats. |
