This paper aims to evaluate the protective potential of prickly pear cactus fresh cladodes (opuntia ficus indica (OFI)) on glycemic disorders, dyslipidemia, prooxidant/antioxidant stress biomarkers and reverse cholesterol transport (by evaluating the activity of lecithin-cholesterol acyltransferase (LCAT)) and paraoxonase (PON1) in rats prematurely exposed to cafeteria diet (CD).
Sixteen young rats were divided into two groups fed CD containing 50 per cent of hyperlipidic diet (HLD) and 50 per cent of junk food mix supplemented or not with 50 g of fresh young cladodes of OFI to 100 g of CD, during 30 days.
OFI cladodes supplementation decreased significantly body weight (p < 0.001), food intake (p < 0.05), adipose tissue weight (p < 0.01), fasting glycemia and glycosylated hemoglobin (p < 0.01), homeostasis model assessment (HOMA-IR) and insulinemia (p < 0.001), levels of cholesterol (C) (p < 0.05) and triacylglycerols (TG) (p < 0.01) in serum and in very low-density lipoproteins (VLDL-C p < 0.05 and VLDL-TG p < 0.01) and improves reverse cholesterol transport by increasing high-density lipoprotein cholesteryl-esters concentrations (p < 0.001) and by stimulating LCAT activity. Moreover, they attenuated lipid peroxidation in VLDL and low-density lipoproteins by increasing atheroprotective activity of PON-1 and in liver and adipose tissue by enhancing enzymatic antioxidant defence.
The young cladodes of OFI because of their antiobesity benefits could constitute a novel functional ingredient in pharmaceutical and nutraceutical applications.
Young cladodes of OFI in rat precociously submitted to a hyperlipidic diet/junk food (cafeteria model) seem to prevent metabolic disorders associated with obesity.
