The objective was to compare the effect of consuming low glycinin soymilk (LGS, 49.5% β‐conglycinin/6% glycinin), conventional soymilk (S, 26.5% β‐conglycinin/38.7% glycinin) or bovine milk (M, 0% β‐conglycinin) on bone mineral density (BMD) and composition of intestinal microbiota in overweight individuals. In a randomized double‐blind study 64 men BMI>25, 18–45 years old consumed 500 ml of either soymilk or bovine milk daily for 3 months. Each product contained fat (1%), energy (200 kcal) and protein (12 g). BMD was determined by DXA and fecal material composition with real‐time quantitative PCR, both at baseline and after 3 months; diet and physical activity were recorded every month. Energy intake (p=0.40), moderate (p=0.21) and strenuous physical activity (p=0.49) did not change during the study period. LGS did not alter BMD and T‐scores (p>0.05); changes in total microbiota (p=0.36), Bacteroides (p=0.27), Bifidobacteria (p=0.07) and Lactobacillus (p=0.06) were not significant among treatments. Dietary intakes of protein, fat, carbohydrates, dietary fiber, Ca, Fe, Mg, P, K, caffeine, vitamins D, B‐12, K, and E were not influenced by LGS, S or M (p>0.05). However, sodium (p=0.02) and vitamin C (p=0.0002) intakes were reduced with LGS consumption. In conclusion, consumption of LGS for three months did not have an effect on bone mineral density, or altered total intestinal microbiota. Grant Funding Source : Illinois Soybean Association
