Subchronic Study of a White Kidney Bean (Phaseolus vulgaris) Extract with α-Amylase Inhibitory Activity

Table 1

Total body weight gain, food consumption, and food utilization rate of rats treated with white kidney beans for 90 days.

Dose (g/kg)	Total body weight gain (g)	Total food consumption (g)	Average food utilization rate (%)
Male
4	400.3 ± 42.2	2305.9 ± 166.9	17.4 ± 0.9
2	414.6 ± 34.1	2366.1 ± 125.8	17.5 ± 0.7
1	400.3 ± 42.2	2289.8 ± 249.6	18.9 ± 0.7
Control	416.2 ± 46.1	2293.1 ± 215.1	18.1 ± 0.8
Female
4	207.0 ± 21.0	1371.2 ± 95.3	15.1 ± 0.5
2	213.8 ± 25.3	1383.9 ± 110.9	15.4 ± 0.7

Control	221.4 ± 26.3	1386.5 ± 110.7	15.9 ± 1.0

Note: values represent mean ± standard deviation (n = 10). Average food utilization rate (%) = (total body weight gain/total food consumption) × 100%. Values of the treatment groups did not differ statistically from the control according to one-way ANOVA at .
