Effect of Soymilk Consumption on Waist Circumference and Cardiovascular Risks among Overweight and Obese Female Adults

Background: soy milk replacement in the diet might havebeneficial effects on waist circumference and cardiovascular riskfactors for overweight and obese subjects. therefore, we are goingto determine the effects of soy milk replacements on the waistcircumference and cardiovascular risk factors among overweightand obese female adults.methods: in this crossover randomized clinical trail, 24 overweight and obese female adults were on a diet with soy milk or thediet with cow’s milk for four weeks. in the diet with soy milk onlyone glass of soy milk (240 cc) was replaced instead of one glassof cow’s milk (240 cc). measurements were done according to thestandard protocol.results: waist circumference reduced significantly following soymilk period (mean percent change in soy milk period for waistcircumference: ?3.79 ± 0.51 vs. ?1.78 ± 0.55 %; p = 0.02 in thecow’s milk period). blood pressure, weight, liver enzymes andglycemic control indices did not changed significantly after soymilk period compared to the cow’s milk period.conclusion: among over weight and obese patients, soy milk canplay an important role in reducing waist circumference. however,soy milk replacement had no significant effects on weight, glycemiccontrol indices, liver enzymes, fibrinogen and blood pressure in ashort term trial.
