Effect of Daily Exposure to an Isolated Soy Protein Supplement on Body Composition, Energy and Macronutrient Intake, Bone Formation Markers, and Lipid Profile in Children in Colombia
ABSTRACT A soy protein – based supplement may optimize bone health , support physical growth , and stimulate bone formation . This study aim ed to assess the effect of a daily soy protein supplement ( SPS ) on nutritional status , bone formation markers , lipid profile , and daily energy and macronutrient intake in children . One hundred seven participants ( 62 girls ) , ages 2 to 9 , started the study and were r and omly assigned to lunch fruit juice with ( n = 57 , intervention group ) or without ( n = 50 , control group ) addition of 45 g ( 230 Kcal ) of a commercial SPS during 12 months ; 84 children ( 51 girls , 33 boys ) completed the study ( 45 and 39 intervention and control , respectively ) . Nutritional assessment included anthropometry and nutrient intakes ; initial and final blood sample s were taken ; insulin-like growth factor-I ( IGF-I ) , osteocalcin , bone specific alkaline phosphatase ( BAP ) , insulin-like growth factor binding protein-3 ( IGFBP-3 ) , cholesterol , triglycerides , low-density lipoprotein ( LDL ) , and high-density lipoprotein ( HDL ) were analyzed . Statistically significant changes ( p < .05 ) in body mass index and weight for age Z scores were observed between groups while changes in body composition were not . Changes in energy , total protein , and carbohydrate intakes were significantly higher in the intervention group ( p < .01 ) . Calorie intake changes were statistically significant between groups ( p < .001 ) , and BAP decreased in both groups , with values within normal ranges . Osteocalcin , IGFBP-3 , and lipid profile were not different between groups . IGF-I levels and IGF/IGFBP-3 ratio increased significantly in both groups . In conclusion , changes in macronutrient and energy intake and nutritional status in the intervention group compared to control group may ensure harmonious and adequate bone health and development
