Abstract
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-55were 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.
