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.
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.
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.
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.
