“…The regulation of blood glucose in chickens is unorthodox and not well understood, yet glucose is an important signal of energy or nutritional status that is integrated into the regulation of feed intake and energy metabolism in mammals. Transient change in plasma glucose level caused by insulin did not alter feed intake in chicks, which is consistent with the previous study in chickens (Simon et al, 2000), but not in mammals (Branton et al, 2014). Therefore, the role of insulin, as an afferent signal for energy stores in broiler chickens remains to be determined.…”

An experiment was conducted to investigate the effect of peripheral insulin treatment on appetite in chicks. Six-d-age chicks with ad libitum feeding or fasting for 3 h before injection received a subcutaneous injection of 0, 1, 3, 5, 10, or 20 IU of insulin or vehicle (saline). The results showed peripheral insulin treatment (1 to 20 IU) did not alter significantly the feed intake in chicks under either ad libitum feeding or fasting conditions within 4 h (p>0.05). Compared with the control, plasma glucose concentration was significantly decreased after insulin treatment of 3, 5, 10, and 20 IU for 4 h in chicks with ad libitum feeding (p<0.05). In fasted chicks, 10 and 20 IU insulin treatments significantly decreased the plasma glucose level for 4 h (p<0.05). Peripheral insulin treatment of 10 IU for 2 or 4 h did not significantly affect the hypothalamic genes expression of neuropeptide Y, proopiomelanocortin, corticotropin-releasing factor and insulin receptors (p>0.05). All results suggest peripheral administration of insulin has no effect on appetite in chicks.

“…The present study, in comparison, found no influence of child age, weight, BMI, child eating behaviors, or parental practices on the effect of milk ED on intake of milk, food, or the entire meal. Discrepancies in the results of these studies may be primarily due to research design and sample characteristics; for example, previous studies used a preloading paradigm in which the varied item was served before the test meal (Branton et al, 2014; Carnell & Wardle, 2007; Cecil et al, 2005; Johnson, 2000; Johnson & Birch, 1994; Johnson & Taylor-Holloway, 2006; Kral et al, 2012), whereas in the present study, the varied milk and test meal were served simultaneously. One characteristic that has been found to influence the adjustment of food intake both in the present study and in some previous preloading studies in children and adults is the sex of the individual (Davy et al, 2007; Faith et al, 2012; Johnson & Birch, 1994; Ranawana & Henry, 2010).…”

“…Some studies suggest that such compensation diminishes from 5 to 12 years of age (Cecil et al, 2005; Johnson & Taylor-Holloway, 2006) and is reduced in children with higher body weight or adiposity (Branton et al, 2014; Johnson, 2000; Johnson & Birch, 1994; Kral et al, 2012). The accuracy of children's compensatory response has also been related to child eating behaviors such as satiety responsiveness as well as parental practices such as controlling feeding and use of food as reward (Carnell & Wardle, 2007; Cecil et al, 2005, Remy, Issanchou, Chabanet, Boggio, & Nicklaus, 2005).…”

Does milk matter: Is children’s intake affected by the type or amount of milk served at a meal?

Increasing the energy density (ED) and portion size of foods promotes additional energy intake, but the effect of similar changes in milk is unknown. Using a crossover design, we tested the effect of varying the ED and portion size of milk served with lunch on preschool children's intake. Lunch was served in childcare classrooms on 4 days to 125 children aged 3-5 y (67 boys; 58 girls). Across the meals, milk was varied in ED (lower-ED [1% fat]; higher-ED [3.25% fat]) and portion size (100% [183 g]; 150% [275 g]). Foods in the meal were not varied; children ate as much of the meal as they wanted. Serving higher-ED milk did not affect milk intake by weight, but increased energy intake from milk by 31±2 kcal compared to serving lower-ED milk (P<0.0001). Serving the 150% portion of milk increased milk intake by 20±3 kcal compared to serving the 100% portion (P<0.0001). Increases in both ED and portion size combined to increase milk intake by 49±4 kcal (63%; P<0.0001). Across all children, food intake decreased when higher-ED rather than lower-ED milk was served, but meal energy intake (food+milk) did not change significantly. This response varied by sex: for boys, serving higher-ED milk decreased food intake by 43±8 kcal (P<0.0001) but did not affect meal energy intake, while for girls, higher-ED milk did not reduce food intake so that meal energy intake increased by 24±10 kcal (P=0.03). Thus, boys adjusted food intake in response to changes in ED of milk consumed with lunch, but girls did not. Serving milk in larger portions promotes intake of this nutrient-dense beverage, but the effects of milk ED on meal intake vary between children.

“…Limitations include lack of a group that did not set goals, uncontrolled timing of the intervention with respect to meals (since pre-meal gaming may suppress increased food intake among normal weight boys 34 ), not assessing body weight, and enrollment in only one region of the country (limiting generalizability). In addition, the SQ2 study was originally powered to detect a change in FV intake, not ED.…”

Improvement in Fruit and Vegetable Consumption Associated with More Favorable Energy Density and Nutrient and Food Group Intake, but not Kilocalories

Background Children generally do not consume adequate fruit and vegetables. Eating more fruit and vegetables may improve energy density and overall diet quality. Objective To investigate whether improvements in fruit and vegetable consumption were associated with improvements in energy density, total calories, and dietary components related to fruits and vegetables. Design Secondary analyses of dietary data from a successful 4-group randomized controlled trial promoting fruit and vegetables. Data were collected at baseline, immediately after gameplay, and 3 months post-intervention. Participants/setting Pre-adolescent child/parent dyads (n=400) were recruited. Eligibility criteria were 4th or 5th grade child (approximately 9–11 years old) with internet access and a parent willing to participate in the intervention. Complete dietary data were collected on 387 of the 400 participants. The videogame was available online on a secure, password-protected website. Main outcome measures Dietary intake was assessed with three unannounced dietary recalls collected at each data collection period via telephone by trained staff using NDSR 2009. Energy density, fruit and vegetable, nutrient, and food consumption were calculated. Statistical analysis performed A 4 (group) × 3 (time) repeated measures analysis of covariance with mixed–effect linear models was used. Covariates included child’s gender, race/ethnicity, and total energy intake as well as parent’s age and household education. Energy was excluded as a covariate in the energy density and energy models. Results Significant changes occurred in energy density. A significant interaction (group × time) was observed (F (6,515) = 2.40, P<0.05) in energy density from food only, while a significant time effect was observed for energy density from all foods and beverages (F (2,388) = 13.75, P<0.0001). Desirable changes were also observed in fruit and vegetable-related dietary components. Conclusions Increasing fruit and vegetable consumption significantly improved energy density and diet quality in pre-adolescent children.
