Technical Abstract: Soybean has beneficial effect in obesity and diabetes. We tested the hypothesis that the beneficial effects are due in part to the modulation of peptide hormones involved in glucose metabolism and obesity by isoflavones, the major phytochemicals in soybean. Lean and obese SHR/N-cp rats were fed AIN-93 diets containing 20% casein (controls) or 20% casein supplemented with 0.1% soybean isoflavones (I), or 0.1 % probiotic mixture (P), or 0.1% mixture of I and P (I+P). Plasma was analyzed for glucose and peptide hormones. Different fat depots were excised and weighed. The total body fat content was lower in rats fed I and I+P comparted to those fed casein or P diets. I, but not P, lowered plasma glucose in both lean and obese phenotypes and lowered ACTH in obese rats. I also lowered plasma insulin, glucagon and leptin in lean rats but not obese rats. P and P+I increased insulin in obese rats and decreased plasma ACTH in lean rats. In conclusion, isoflavones have beneficial effects in obesity and on glucose metabolism. The beneficial effect appears in part to be due to modulation of peptide hormones.
