“…It is well-known that dietary fibre plays an essential role in promoting several physiological and metabolic beneficial effects, particularly as a bulking agent, normalising intestinal motility, preventing constipation, and decreasing the intestinal absorption of cholesterol and glucose [ 27 , 28 ]. The dried pineapple used in this study contains a high dietary fibre content of approximately 9% by weight.…”

Background Hypercholesterolemia is a major risk factor for cardiovascular disease. It has been reported that pineapple contains healthy nutrients and phytochemicals associated with antioxidant and anti-inflammatory capacities. No investigation exists concerning the effect of pineapple consumption modulating hypercholesterolemia-induced cardiac damage in high-cholesterol diet (HCD)-fed rats. This study evaluated the effect of pineapple consumption on lipid-lowering, cardiac oxidative stress and inflammation in HCD-fed rats. Methods Male Sprague–Dawley rats were fed with HCD, in the presence and absence of Pineapple (Ananas comosus L.) cv. Pattavia powder for 8 weeks. Then, serum lipid profiles, liver and renal function tests, cardiac oxidative stress and pro-inflammatory cytokines were determined. Results Daily pineapple consumption reduced weight gain, serum lipid profiles, atherogenic coefficient (AC), cardiac risk ratio (CRR), and liver enzyme activity, without causing renal dysfunction. Pineapple consumption also restores cardiac protein carbonyl (cPC) content, reduces cardiac malondialdehyde (MDA), cardiac pro-inflammation cytokine IL-6 and IL-1β levels. Conclusion Pineapple possesses antioxidant and lipid-lowering properties and daily consumption alleviates hypercholesterolemia-induced cardiac lipid peroxidation and pro-inflammation elevation in an in vivo model. This study demonstrates that pineapple is a potential candidate for cardioprotection against hypercholesterolemia.

“…Bromelain and phenolic compounds found in pineapple peel has been reportedly shown to decrease cholesterol in obesity by breakdown of cholesterol plaques [ 57 ]. Also presence of high amount of soluble fibres in pineapple peels can also lower cholesterol by binding to cholesterol in the stomach and small intestine, ultimately reducing its absorption [ 58 , 59 ].…”

“…The glucose adsorption capacity (GAC) of the DFs was determined according to Hu & Zhao (2018) with slight modifications. The sample (0.25 g) of each DF was mixed with 50 mL of 0.1 mol L −1 glucose solution and incubated at 37°C in a water bath for 60 min.…”

“…The aqueous dispersions of DFs samples (100 mg) were prepared and centrifuged at 2570 g for 15 min. The obtained supernatants were diluted to appropriate concentrations and obtained aqueous extracts of samples were analysed for total antioxidant capacity using ABTS cation radical (ABTS •+ ) assay according to Hu & Zhao (2018). Ascorbic acid at similar concentrations was used as a positive control.…”

Summary The aim of the study was to estimate the optimum method to obtain water‐soluble (WS‐DF) and alkali‐soluble (AS‐DF) dietary fibres fibres from defatted rice bran (DRB) to develop functional components for food. The different pre‐treatments of DRB, such as ultrasound (US) treatment, hydrolysis by cellulase (HC) and combined treatment (HC‐US), were compared with hot‐water (HWT) treatment on yields, and structural, physicochemical, and functional properties of WS‐DF and AS‐DF. Results showed that amounts of WS‐DF (5.54–9.03 g/100 g) and AS‐DF (7.22–9.58 g/100 g), and total dietary fibre (TDF) (42.21–45.44 g/100 g) obtained from the DRB after US, HC and HC‐US treatments were significantly higher than that after HWT (6.36, 5.65 and 31.92 g/100 g, respectively). The FT‐IR indicated that the effect of applied treatments on the changes of the chemical structure of polysaccharides was stronger for the WS‐DF than that for the AS‐DF. Scanning electron microscopy (SEM) showed that the surfaces of US‐treated DFs particles were much more fractured than those after the HWT and HC. The combined HC‐US treatment at 50°C for 30 min significantly enhanced the purity (85–91%) and homogeneity of RB DFs structure resulting in increased water‐holding, swelling and glucose adsorption capacities compared to conventional processes maintaining acceptable bioactivity. Our study showed that conventional hot water extraction could be replaced with the ultrasonication technology as an effective tool for the modification of rice bran DFs’ structure and functional properties.
