Effect of Ajwa date seed powder on visceral fat depots and inflammatory response in high fat fed Sprague Dawley female rats

Background: Central obesity a worldwide metabolic and cosmetic problem poses significant health risk. Ajwa date seed has antioxidant property and its high fiber content may prevent fat absorption and reduce fat deposition. Objective: To evaluate the effect of Ajwa date seed powder on visceral fat depots and inflammatory response in high fat fed Sprague Dawley female rats. Methodology: Thirty-six healthy rats of four weeks age were divided into three groups and followed for 12 weeks. Group A (normal control) received regular diet. Group B (HFD control) received high fat diet, while group C (HFD+Ajwa group) received high fat diet along with 2% Ajwa date seed powder. Body weight was measured weekly. Blood sample was drawn for the estimation of serum IL-6 and leptin levels by ELISA method at 12th week. After which rats were euthanized; perinephric fat was removed and weighed in grams. Results: HFD+Ajwa group gained less body weight as compared to HFD control group (p value = 0.012). There was a remarkable reduction in perinephric fat weight (p value ≤ 0.001) and level of IL-6 in HFD+Ajwa group (p value ≤ 0.001) as compared to HFD control. There was no significant difference in serum leptin level of the rats of all groups (p value = 0.567). Conclusion: Ajwa date seed can prevent visceral adiposity and gain in body weight. Moreover, it has anti-inflammatory effect; but no significant effect on satiety hormone. Key Words: Obesity, Visceral fat, P. dactylifera L (Ajwa date) seed, IL-6, Leptin.
