    Effect of sugars in solution on subjective appetite and short-term food intake regulation in normal weight 9 to 14 year old boys
    (Mount Saint Vincent University, 2012) Van Engelen, Marissa; Bellissimo, Nick
    To examine the hypothesis that the physiologic regulation of short-term food intake (FI) in boys is affected by sugars source, the following study was conducted. The objective was to describe the effect of consuming 200 kcal of glucose, high-fructose corn syrup-55 (HFCS-55) and sucrose 60 min before a pizza meal on subjective appetite and short-term FI regulation compared to a Sucralose® control. On four separate mornings, fifteen normal weight (NW) boys received in random order one of the four equally sweetened sugars solutions 2 h after consuming a standardized breakfast. Food intake at an ad libitum pizza meal was measured 60 min after each treatment. Subjective appetite was measured at 15 min time intervals until the test lunch and immediately after. Only glucose resulted in a statistically significant decrease in FI (975 kcal ± 58) compared to the Sucralose® control solution (P<0.01). Mean FI after sucrose and HFCS-55 were not statistically different. Caloric compensation, a measure of FI regulation, after the glucose, sucrose and HFCS-55 solutions were scored 76%, 26% and 26%, respectively, but did not differ (P=0.07). Average appetite (AA) was higher after the HFCS-55 solution compared to glucose (P<0.05). Change from baseline AA scores following sucrose were significantly higher compared to the other three treatments (P<0.01), which suggest that hunger returned more quickly after sucrose. The energy content of the preloads, expressed as per kcal/kg body weight (BW), inversely associated with FI after sucrose and HFCS-55 (P<0.05), but not after glucose (P=0.09), suggesting dose was less of a factor after glucose compared to after sucrose and HFCS-55. Fat-mass (FM) positively correlating with FI after the control, sucrose and HFCS-55 solutions (P<0.05) suggests body composition is also a factor of FI regulation. In summary, only glucose suppressed FI at a test meal 60 min later, as a result of greater physiological effects on FI compared to isovolumetric and isocaloric solutions of sucrose and HFCS-55. In conclusion, the short-term regulation of FI in NW 9- to 14-year-old boys was affected by sugars source, treatment dose and body composition.

    Effect of sugars-sweetened commercial beverages on subjectivity appetite and short-term food intake regulation in normal weight and overweight/obese 9 to 14 year old girls
    (Mount Saint Vincent University, 2012-02) Bennett, Lorianne; Bellissimo, Nick
    The following study was conducted to examine the hypothesis that 1% chocolate milk suppresses short-term food intake (FI) to a greater extent than other sugars containing beverages, but the effect will be diminished in overweight and obese (OW/OB) girls. The objective was to determine the effect of isovolumetric drinks of (350ml) 1% chocolate milk, fruit drink, and cola 60 min before a pizza meal on subjective appetite, and short-term FI compared to a water control in 9-14 year old normal weight (NW) and OW/OB girls. A decrease in FI after 1% chocolate milk occurred in NW (n=12) but not OW/OB (n=11) girls. None of the other beverages suppressed FI in either group. In the pooled sample (n=23) a decrease in FI occurred after cola and 1% chocolate milk but not fruit drink, which suggests macronutrient composition was the major determinant on FI suppression. Lower prospective food consumption (PFC) and desire to eat (DTE) scores in NW girls after 1% chocolate milk, when corrected for the energy content of the preload, suggests that 1% chocolate milk is a potent regulator of appetite and FI in NW girls. Subjective appetite, body composition, or cognitive restraint, were not strong determinants of FI. In conclusion, most sugars containing beverages suppressed FI, but the response was affected by macronutrient composition, energy content of the beverages, and body weight status.

    Effect of sugars-sweetened commercial beverages on subjectivity appetite and short-term food intake regulation in normal weight and overweight/obese 9-14 year old boys
    (Mount Saint Vincent University, 2012-04) Poirier, Kelly Lynn; Bellissimo, Nick
    This study was conducted to test the hypothesis that 1% chocolate milk will increase mealtime satiation and decrease short-term food intake (FI) to a greater extent than other isovolumetric sugars-sweetened beverages in normal weight (NW) and overweight/obese (OW/OB) boys, although the effect will be diminished in OW/OB boys. The primary objective was to determine the effect of isovolumetric (350 ml) preloads of fruit drink, cola and 1% chocolate milk on short-term FI and subjective appetite when compared to a water control in 9-14 year old NW and OW/OB boys. On four separate mornings and in random order, boys consumed a calorie-free water control, fruit drink (154 kcal), cola (158 kcal) or 1% chocolate milk (224 kcal) beverage 2 hours after a standardized breakfast. Boys significantly reduced FI after cola (NW: 894 ± 54; OW/OB: 986 ± 75) and 1% chocolate milk (NW: 844 ± 52; OW/OB: 912 ± 63) compared to a water control (NW: 1046 ± 51; OW/OB: 1050 ± 49). Caloric compensation (CC) scores were not significantly different between groups for the fruit drink (NW: 44% vs. OW/OB: 16%, p=0.56), cola (NW: 96% vs. OW/OB: 40%, p=0.27) or 1% chocolate milk (NW: 90% vs. OW/OB: 61%, p=0.24) treatments. When corrected for the energy content of the treatment, fullness was higher after cola (p=0.02), and prospective food consumption (PFC) lower after 1% chocolate milk (p=0.009) compared to the fruit drink. PFC and DTE were the strongest and weakest predictors of FI, respectively. BW was positively associated with FI and inversely associated with CC in OW/OB, but not NW boys (P<0.05). In OW/OB, the treatment dose of cola (kcal/kg BW) was inversely associated with FI (P<0.05). In conclusion, cola and 1% chocolate milk suppressed FI in boys, however, the effect on FI was dependent on macronutrient composition, treatment dose and body composition.
