Abstract

Hypocholesterolaemic and hypoglycaemic effect of banana blossom were studied in high-cholesterol fed rats. Experimental groups were fed for 4 weeks, with casein as the basal diet (CN), in comparison with two diets containing 0.5% cholesterol (CD) and 0.5% cholesterol + 21% banana blossom powder (CDB). Serum total cholesterol, non-HDL-cholesterol level, and serum glucose concentrations were lower in CDB fed group compared with CD fed group. Lower serum cholesterol and glucose level (P < 0.05) in CDB fed group were followed by higher faecal weight, caecal weight, caecal Lactobacilli, and Bifidobacteria population in CDB fed group compared to CD diet fed group. Lower serum AST level in banana blossom fed rats showed the reduction in oxidative stress induced by high cholesterol diet. Based on these data, it could be speculated that banana blossom incorporated experimental diets may modulate the hypocholesterolaemic and hypoglycaemic responses in Wistar rats.

Highlights

Blossom of the banana plant (Musa acuminata Colla), byproduct of banana cultivation, is often consumed as a vegetable in many Asian countries such as Sri Lanka, Malaysia, Indonesia, and the Philippines [1]
Serum Total cholesterol (TC) concentration was lower (P < 0.05) in cholesterol diet with 21% banana blossom (CDB) fed group compared to cholesterol diet (CD) fed group and banana blossom (21%) in CDB diet countered the increase in total cholestreol induced by 0.5% cholesterol (Figure 1)
Lower serum total cholesterol and non-HDL cholesterol (HDL-C) level in CDB fed group were supported by higher crude fibre content in banana blossoms and faecal weight in rats fed CDB diet and were in agreement with previous studies showing that dietary fibre in experimental diets modulates serum cholesteol level in rats [23] and a reduction in non HDL-C in banana blossom supplemented diet fed group may be useful as a therapeutic treatment

Summary

Introduction

Blossom of the banana plant (Musa acuminata Colla), byproduct of banana cultivation, is often consumed as a vegetable in many Asian countries such as Sri Lanka, Malaysia, Indonesia, and the Philippines [1]. In Sri Lanka, it is consumed as a curry as well as a boiled or deep fried salad with rice and wheat bread [2]. High levels of dietary fibre intake are associated with significantly lower prevalence rates for coronary heart disease, stroke, and peripheral vascular disease [6,7,8]. Average fibre intakes for children and adults are alarmingly less than that of the recommended level [9]. Food components with antioxidant properties may prevent cardiovascular diseases by inhibiting the oxidative damage to LDL-cholesterol [10]
