The Goran Lab aims to discover how the body regulates where excess fat is deposited, how increased body fat affects our health, and how this is all regulated during growth and development and across different segments of the population. We are interested in understanding the mechanism linking fat accumulation to risk of diabetes, heart disease, and fatty liver disease, and how this is established early in life from a developmental perspective. We are especially interested in examining how early feeding and dietary sugar affect development of the gut microbiome, obesity, the brain and cognitive function. We are also doing clinical trials to examine how these links can be reversed with novel dietary interventions.

Methods Participants were 157 Hispanic mother‐infant pairs. Human milk samples were collected at 1 month. Nineteen individual HMOs were analyzed using high‐performance liquid chromatography, and secretor status was determined by the presence of 2′‐fucosyllactose or lacto‐N‐fucopentaose (LNFP) I. Infant weight was measured at 1 and 6 months. Path analysis was used to test effects of HMO composition on infant weight gain, adjusting for maternal age, prepregnancy BMI, and infant age, sex, and birth weight. Results In the total sample, higher LNFPII predicted lower infant weight gain (g 1 = −4.1, P = 0.004); this was observed in both nonsecretor (g 1 = −3.0, P = 0.006) and secretor groups (g 1 = −4.7, P = 0.014). In the nonsecretor group, higher lacto‐N‐neotetraose (g 1 = 7.6, P = 0.011) and disialyllacto‐N‐tetraose (g1 = 14.3, P = 0.002) predicted higher infant weight gain. There were no other associations in the secretor group. Conclusions Our data suggest that higher LNFPII in human milk may decrease obesity risk across all infants, whereas higher lacto‐N‐neotetraose and disialyllacto‐N‐tetraose may increase obesity risk in infants of nonsecretors only. }, keywords = {}, pubstate = {published}, tppubtype = {article} } Abstract Objective The aim of this study was to determine whether human milk oligosaccharides (HMOs) at 1 month predicted infant weight gain at 6 months and whether associations varied by HMO secretor status.

Prebiotics have been demonstrated to suppress appetite in both adults and children. Therefore, HMOs may affect infant eating behaviour. Objective To determine if HMOs in breast milk are associated with eating behaviour in Hispanic infants. Methods Cross‐sectional analysis of a prospective cohort of Hispanic mother‐infant dyads (1‐month, n = 157; 6‐months, n = 69). Breast milk samples were screened for 19 HMOs using high pressure liquid chromatography, and eating behaviour was assessed using the Baby Eating Behaviour Questionnaire (BEBQ). We conducted multiple linear regressions to examine associations between HMOs and BEBQ scores, adjusted for maternal pre‐pregnancy BMI, infant sex, birthweight, delivery mode and number of breastfeedings per day. We stratified by HMO secretor status—a genetic determinant of the types of HMOs produced. Results At 1 month, LNnT (lacto‐N‐neotetraose; P = .04) was negatively associated with food responsiveness in the total sample, while DFLNT (difucosyllacto‐N‐tetrose; P = .03) and DSLNT (disialyl‐LNT; P = .04) were negatively associated with food responsiveness in secretors only.

Indicators of dietary carbohydrate quality including added sugar consumption, glycemic load, and glycemic index have been linked with weight gain, whereas fiber may protect against obesity. However, these dietary factors have not been examined during the postpartum period. Objectives The aim of this study was to determine whether dietary sugars and fiber intake were associated with changes in postpartum weight. Methods We examined Hispanic women from the longitudinal Southern California Mother's Milk Study (n = 99) at 1 and 6 mo postpartum. Maternal assessments included height, weight, and dietary intake based on 24-h diet recalls. We used multivariable linear regression to examine the relation between maternal diet and change in postpartum weight after adjusting for maternal age, height, and energy intake. Results Higher intake of added sugar was associated with postpartum weight gain (β: 0.05; 95% CI: 0.004, 0.10; P = 0.05). In addition, a half 8-ounce (8 fluid ounces = 236.6 mL) serving per day increase in soft drinks was associated with a 1.52-kg increase in weight (95% CI: 0.70, 2.34 kg; P < 0.001).
