Body composition of young male rats fed on diet added with taro (Colocasia esculenta) flour

Abstract

Purpose

The purpose of this study is to assess the effect of a diet added with taro (Colocasia esculenta) flour on the body composition of rats.

Design/methodology/approach

Weanling male rats were divided into Control (n = 11) and experimental groups (Taro, n = 12); experimental rats were fed on taro for 90 days. Food intake, body mass and length were evaluated on a weekly basis. Body composition was assessed through dual-energy X-ray absorptiometry and intra abdominal fat mass was measured at the end of 90 days.

Findings

Taro group recorded protein intake (55.5 ± 14.1 vs 43.8 ± 12.8 kcal, P < 0.009), body mass (between 40 and 90 days, P < 0.05), fat mass (147.3 ± 7.7 vs 99 ± 6.1 g, P < 0.001), lean mass (282.8 ± 4 vs 253.5 ± 7 g, P < 0.001), trunk fat mass (97.1 ± 7.7 vs 71.5 ± 4.1 g, P < 0.010), as well as intra-abdominal (31.3 ± 1.9 vs 21.1 ± 1.7 g, P < 0.001), epididymal (9.2 ± 0.8 vs 4.7 ± 0.5 g, P < 0.001) and retroperitoneal (14.2 ± 0.9 vs 8.8 ± 1.2 g, P < 0.002) fat mass higher than that of the Control group.

Originality/value

Taro flour would show anabolic effects on body compartments of rats. The extrapolation of these findings herein recorded for rats to humans requires caution; however, it is necessary conducting further studies to investigate potentials anabolic effects of taro (Colocacia esculenta) flour on the body composition of physical training models.
