This study tested whether varying the portion of low-energy-dense vegetable soup served at the start of a meal affects meal energy and vegetable intakes in children. Subjects were 3- to 5-year-olds (31 boys and 41 girls) in daycare facilities. Using a crossover design, children were served lunch once a week for four weeks. On three occasions, different portions of tomato soup (150, 225, and 300 g) were served at the start of the meal, and on one occasion no soup was served. Children had 10 min to consume the soup before being served the main course. All foods were consumed ad libitum. The primary outcomes were soup intake as well as energy and vegetable intake at the main course. A mixed linear model tested the effect of soup portion size on intake. Serving any portion of soup reduced entrée energy intake compared with serving no soup, but total meal energy intake was only reduced when 150 g of soup was served. Increasing the portion size increased soup and vegetable intake. Serving low-energy-dense, vegetable soup as a first course is an effective strategy to reduce children's intake of a more energy-dense main entrée and increase vegetable consumption at the meal.  相似文献

Orosensory exposure to sweetness has been shown to be important in satiation, whereas the effect of exposure to a salty taste on satiation is not known. The primary objective was to investigate the effect of orosensory exposure time to and intensity of saltiness in soup on ad libitum intake. The secondary objective was to investigate the effect of intensity on bite size. Fifty-five healthy men consumed ad libitum from both a low-salt (LS) and a high-salt (HS) creamy tomato soup in 2 exposure time conditions ("long" and "short") and a free condition ("free"). Bites were administered and controlled via a pump. In the long condition, bites of 5 g were administered in 2 s at intervals of 5 s (exposure time: 24 s/min). In the short condition, bites of 15 g were administered in 3 s at intervals of 15 s (exposure time: 12 s/min). The eating rate was equal in the long and short conditions (60 g/min). In the free condition, participants adjusted their bite sizes at intervals of 15 s. The short condition resulted in ~34% higher ad libitum intake compared to the long condition (P < 0.001); there was no interaction with intensity. Ad libitum intake of HS soup was ~9% lower than LS soup (P < 0.001). The free condition showed that HS soup was consumed with smaller bite sizes during the first half of the intake period (P < 0.05). Longer orosensory exposure and higher saltiness intensity both decreased food intake, although orosensory exposure had more impact than intensity. Prolonging the orosensory exposure per food unit may be helpful to reduce food intake.  相似文献

Taste is involved in food preference and choice, and it is thought that it can modulate appetite and food intake. The present study investigated the effect of savory or sweet taste on satiation, reward, and food intake and according to individual differences in eating behavior traits underlying susceptibility to overeating. In a crossover design, 30 women (BMI = 22.7 ± 2.3; age = 21.9 ± 2.6 y) consumed a fixed energy preload (360 kJ/g) with a savory, sweet, or bland taste before selecting and consuming items from a test meal ad libitum. Sensations of hunger were used to calculate the satiating efficiency of the preloads. A computerized task was used to examine effects on food reward (explicit liking and implicit wanting). The Three Factor Eating Questionnaire was used to compare individual differences in eating behavior traits. Satiation and total food intake did not differ according to preload taste, but there was an effect on explicit liking and food selection. The savory preload reduced liking and intake of high-fat savory foods compared to sweet or bland preloads. The eating behavior trait disinhibition interacted with preload taste to determine test meal intake. Higher scores were associated with increased food intake after the sweet preload compared to the savory preload. Independent of preload taste, disinhibition was associated with lower satiating efficiency of the preloads and enhanced implicit wanting for high-fat sweet food. Savory taste has a stronger modulating effect on food preference than sweet or bland taste and may help to preserve normal appetite regulation in people who are susceptible to overeating.  相似文献

Long-term reductions in the quantity of food consumed, and a shift in intake away from energy dense foods have both been implicated in the potent bariatric effects of Roux-en-Y gastric bypass (RYGB) surgery. We hypothesised that relative to pre-operative assessment, a stereotypical shift to lower intake would be observed at a personalised ad libitum buffet meal 24 months after RYGB, driven in part by decreased selection of high energy density items. At pre-operative baseline, participants (n = 14) rated their preference for 72 individual food items, each of these mapping to one of six categories encompassing high and low-fat choices in combination with sugar, complex carbohydrate or and protein. An 18-item buffet meal was created for each participant based on expressed preferences. Overall energy intake was reduced on average by 60% at the 24-month buffet meal. Reductions in intake were seen across all six food categories. Decreases in the overall intake of all individual macronutrient groups were marked and were generally proportional to reductions in total caloric intake. Patterns of preference and intake, both at baseline and at follow-up appear more idiosyncratic than has been previously suggested by verbal reporting. The data emphasise the consistency with which reductions in ad libitum food intake occur as a sequel of RYGB, this being maintained in the setting of a self-selected ad libitum buffet meal. Exploratory analysis of the data also supports prior reports of a possible relative increase in the proportional intake of protein after RYGB.  相似文献

The objective of this study was to investigate the effect of taste of a 24-h diet on subsequent food preferences (food choice and intake of specific food categories) and satiety. We used a crossover design, consisting of a 24-h fully controlled dietary intervention, during which 39 healthy subjects consumed diets that were predominantly sweet tasting, savory tasting, or a mixture. The diets were similar in energy content, macronutrient composition, and number of different products used. Following the intervention an ad libitum lunch buffet was offered the next day, consisting of food items differing in taste (sweet/savory) and protein content (low/high) and intake was measured. The results showed that the taste of the diet significantly altered preference for food according to their taste properties (p<0.0001); after the savory diet, intake of sweet foods was higher than of savory foods. After the sweet diet, savory foods tended to be preferred (p=0.07). No interaction was seen between the taste of the diet and food preference according to their protein content (p=0.67). No differences in total energy intake (kJ) at the ad libitum lunch buffet were observed (p=0.58). It appears that in healthy subjects, taste of a 24-h diet largely affects subsequent food preferences in terms of sensory appetite, whereby savory taste exerts the strongest modulating effect. Taste of a 24-h diet has no effect on macronutrient appetite.  相似文献

BACKGROUND: Sensory-specific satiety has been found to play an important role in food choice and meal termination, and it might be a factor contributing to obesity. OBJECTIVE: We hypothesized that obese and normal-weight people have different sensitivities to sensory-specific satiety for high-fat foods. DESIGN: Sensory-specific satiety was measured in 21 obese [x body mass index (BMI; in kg/m(2)): 33.1] and 23 normal-weight (BMI: 22.8) women who were matched for restrained eating behavior, physical activity, age, and smoking behavior. Food intake, appetite ratings, and liking scores before and after an ad libitum lunch were measured. Products differed in fat content and taste (ie, low-fat sweet, low-fat savory, high-fat sweet, and high-fat savory), and the subjects tested all 4 products. In the first study, sandwiches were tested; in the second study, snacks were tested. RESULTS: Sensory-specific satiety for all products was observed in both subject groups. No significant differences were observed between the obese and normal-weight subjects in either sensory-specific satiety or food intake for any of the products or product categories tested. Taste (sweet or savory) had a significantly (P < 0.05) stronger effect on sensory-specific satiety than did fat content. Appetite ratings strongly decreased after lunch, and appetite for a meal or snack after lunch was significantly higher in obese than in normal-weight subjects, whereas scores before lunch did not differ significantly. CONCLUSIONS: Obese and normal-weight people do not differ in their sensitivity to sensory-specific satiety, and factors other than fat content have the greatest effect on sensory-specific satiety.  相似文献

After food consumption, the motivation to eat (wanting) decreases and associated brain reward responses change. Wanting-related brain responses and how these are affected by consumption of specific foods are ill documented. Moreover, the predictive value of food-induced brain responses for subsequent consumption has not been assessed. We aimed to determine the effects of consumption of sweet and savory foods on taste activation in the brain and to assess how far taste activation can predict subsequent ad libitum intake. Fifteen healthy men (age: 27 ± 2 y, BMI: 22.0 ± 1.5 kg/m2) participated in a randomized crossover trial. After a >3-h fast, participants were scanned with the use of functional MRI before and after consumption of a sweet or savory preload (0.35 L fruit or tomato juice) on two occasions. After the scans, the preload juice was consumed ad libitum. During scanning, participants tasted the juices and rated their pleasantness. Striatal taste activation decreased after juice consumption, independent of pleasantness. Sweet and savory taste activation were not differentially affected by consumption. Anterior cingulate taste activation predicted subsequent ad libitum intake of sweet (r = -0.78; P < 0.001(uncorrected)) as well as savory juice (r = -0.70; P < 0.001(uncorrected)). In conclusion, we showed how taste activation of brain reward areas changes following food consumption. These changes may be associated with the food's physiological relevance. Further, the results suggest that anterior cingulate taste activation reflects food-specific satiety. This extends our understanding of the representation of food specific-appetite in the brain and shows that neuroimaging may provide objective and more accurate measures of food motivation than self-report measures.  相似文献

The aim of the experiment was to determine the effects of eating a sweet food either as a first course or as a third course on intake during a three-course lunch. Twenty normal weight, non-dieting male subjects were run twice in a counter-balanced design. The first and third courses were interchanged and consisted of either a sweet (candy bar) or savory (cheese or crackers) food, both of similar palatabilities and energy densities. Intake of these foods, when they were eaten as a first course, was the same. The two first courses had no differential effects on intake of the middle course (spaghetti with meat sauce and a salad), which was the same in both conditions. Intakes in the third course did not differ significantly between conditions, but intake was slightly higher when the candy was eaten. Intake of the candy bar was similar in the first and third courses, but intake of the cheese on crackers was significantly lower (p less than 0.0007) as the third course. Total energy intake over the entire meal was 6% higher when the candy bar was eaten last, but this was not significant. Thus, there was no indication that eating candy as a first course affected appetite and food intake differently from eating the same amount of a non-sweet food such as cheese on crackers, which was similar in energy density and palatability. However, more studies with different foods in a situation more similar to a normal meal are needed before it can be concluded that sweet and savory foods at the start or end of a meal always have the same effects on appetite and food intake.  相似文献

Foods with different satiating effects in humans   总被引:4,自引:2,他引:2  
The aim of this study was to identify particular properties of foods that can affect satiety. Two levels (50 and 200 kcal) of three preloads (tomato soup, melon, cheese on crackers) were given just before two different second courses (macaroni and beef casserole, grilled cheese sandwiches), allowing us to examine the effects of caloric level, energy density, and sensory-specific satiety on food intake in normal weight, non-dieting males. Eating time and initial palatability ratings were held constant. Soup was found to reduce second course intake significantly more than the other preloads. This reduction could be partially accounted for by the low energy density of tomato soup; however, soup reduced intake more than the melon preload, which was matched for energy density. Sensory-specific satiety did not explain the satiating efficiency of the soup. Thus, during a meal, tomato soup is more satiating than the melon and cheese on crackers. Further studies are required to determine why these foods have different effects and to determine whether soup consumption can be beneficial in weight reduction programs.  相似文献

Soup preloads in a variety of forms reduce meal energy intake   总被引:1,自引:0,他引:1  
Flood JE  Rolls BJ 《Appetite》2007,49(3):626-634
Consuming soup can enhance satiety and reduce energy intake. Little is known about the influence on energy intake and satiety of varying the form of soup by altering the blending of ingredients. We tested the effects on meal intake of consuming different forms of soup as a preload: broth and vegetables served separately, chunky vegetable soup, chunky-pureed vegetable soup, or pureed vegetable soup. Normal-weight men and women (n = 60) came to the laboratory for lunch once a week for 5 weeks. Each week, one of four compulsory preloads, or no preload, was consumed prior to lunch. A test meal was consumed ad libitum 15 min after the soup was served. Results showed that consuming soup significantly reduced test meal intake and total meal energy intake (preload + test meal) compared to having no soup. When soup was consumed, subjects reduced meal energy intake by 20% (134+/-25 kcal; 561+/-105 kJ). The type of soup had no significant effect on test meal intake or total meal energy intake. Consuming a preload of low-energy-dense soup, in a variety of forms, is one strategy for moderating energy intake in adults.  相似文献

Expectations about a food’s satiating capacity predict self-selected portion size, food intake and food choice. However, two individuals might have a similar expectation, but one might be extremely confident while the other might be guessing. It is unclear whether confidence about an expectation affects adjustments in energy intake at a subsequent meal. In a randomized cross-over design, 24 subjects participated in three separate breakfast sessions, and were served a low-energy-dense preload (53 kcal/100 g), a high-energy-dense preload (94 kcal/100 g), or no preload. Subjects received ambiguous information about the preload’s satiating capacity and rated how confident they were about their expected satiation before consuming the preload in its entirety. They were served an ad libitum test meal 30 min later. Confidence ratings were negatively associated with energy compensation after consuming the high-energy-dense preload (r = −0.61; p = 0.001). The same relationship was evident after consuming the low-energy-dense preload, but only after controlling for dietary restraint, hunger prior to, and liking of the test meal (p = 0.03). Our results suggest that confidence modifies short-term controls of food intake by affecting energy compensation. These results merit consideration because imprecise caloric compensation has been identified as a potential risk factor for a positive energy balance and weight gain.  相似文献

Sixty female white-footed mice (Peromyscus leucopus) were fed either ad libitum or 70% ad libitum diets for 5 weeks. During the last 3 weeks of feeding a polychlorinated biphenyl (Aroclor 1254) was incorporated into the diets at levels of 0,25, or 100 ppm (based on ad libitum intake). Polychlorinated biphenyl ingestion increased liver weights, reduced pentobarbital-induced sleep times, and generally reduced plasma corticoid levels but had no effect on reproductive organ weights or the incidence of estrus (as judged by vaginal smears). Feed restriction caused marked atrophy of the ovaries and uterus and reduced the incidence of estrus.  相似文献

The purpose of this experiment was to determine whether optimal salt levels in soup were influenced by consumption of a meal either high or low in salt. Following a lunch high in salt, optimal salt levels were reduced; no change in optimal levels followed a lunch low in salt. No changes in optimal sweet preference were observed for either condition. It is suggested that changes in optimal salt levels are due to factors associated with exposure to salt during the meal.  相似文献

The energy density (ED; kcal/g) of foods, when manipulated in the laboratory, affects short-term energy intake. The aim of this study was to examine if, when given a choice, dietary ED (foods only) and energy intake (expressed as a percentage of subjects' estimated daily energy requirement; EER) at a self-selected, single meal differ for teens born with a different familial predisposition to obesity and as a function of their sex. Subjects (13 males, 17 females) were 12 years of age and born at high risk (HR; n = 15) or low risk (LR; n = 15) for obesity based on maternal pre-pregnancy body mass index (BMI; kg/m2). The buffet meal, served for lunch and consumed ad libitum, consisted of a variety of foods and beverages with a range in ED. HR subjects consumed a more energy-dense meal (foods only) than LR subjects (1.84 vs. 1.42 kcal/g; P = 0.02) and males consumed a more energy-dense meal than females (1.83 vs. 1.43 kcal/g; P = 0.03). Total energy intake, when expressed as a percentage of subjects' daily EER, did not differ between HR and LR subjects (42% vs. 33%; P = 0.16). Males, compared to females, consumed ~ 59% more energy from foods and beverages during the meal (46 vs. 29%; P = 0.008). During a single multi-item lunch meal, teens with a familial predisposition to obesity and males, independent of their obesity risk status, self-selected a more energy-dense meal. Familial risk for obesity, through either genetic or environmental pathways, may facilitate a more energy-dense diet.  相似文献

BACKGROUND/OBJECTIVESThe exposure to sucrose in rats has mimic abnormalities attributed to metabolic syndrome (MetS). The effects of honey bee and “free” glucose and fructose, have not been explored in this context. The aim was to expose Wistar rodents to sucrose solution (SS), honey solution (HS) and fructose/glucose solution (GFS) at 30% to assess their effects.SUBJECTS/METHODSHS (n = 10), SS (n = 10) and GFS (n = 10) groups were formed. Solutions were ad libitum along 14-weeks.RESULTSBetween solutions consumptions, honey was significantly 42% higher (P = 0.000), while similar consumption was observed among GFS and SS. The feeding pattern of HS consumption was irregular along experiment; while the food intake pattern showed the similar trend among groups along time. Non statistical differences were obtained in any biochemical and anthropometric measure, however, a higher concentration of leptin (721 ± 507 pg/mL), lower concentration of total cholesterol (TC; 48.87 ± 2.41 mg/100 mL), very low density lipoprotein (VLDL; 16.47 ± 6.55 mg/100 mL) and triglycerides (82.37 ± 32.77 mg/100 mL) was obtained in SS group. For anthropometric values, HS showed less total adipose tissue (AT; average 26 vs. 31–33 g) and adiposity index (average 6.11 vs. 7.6). Due to sugar-sweetened beverages consumption increases the risk for the development of chronic diseases; correlations between fluid intake and anthropometric and biochemical parameters were assessed. A moderate correlation was obtained in groups with the weight of total AT and solution intake; for the weight gain in GFS group and for triglycerides in HS and GFS. The highest hepatic tissue damage was observed in SS group with multiple intracytoplasmic vacuoles, atypia changes, moderate pleomorphism and hepatocellular necrosis.CONCLUSIONSIn spite of the significantly higher consumption of HS, biochemical, anthropometrical and histological effects were not remarkably different in comparision to other sweeteners.  相似文献

BackgroundThe effect of eating speed on energy intake by weight status is unclear.ObjectiveTo examine whether the effect of eating speed on energy intake is the same in normal-weight and overweight/obese subjects.DesignThe effect of slow and fast eating speed on meal energy intake was assessed in a randomized crossover design.Participants/settingThirty-five normal-weight (aged 33.3±12.5 years; 14 women and 21 men) subjects and 35 overweight/obese (44.1±13.0 years; 22 women and 13 men) subjects were studied on 2 days during lunch in a metabolic kitchen.InterventionThe subjects consumed the same meal, ad libitum, but at different speeds during the two eating conditions. The weight and energy content of the food consumed was assessed. Perceived hunger and fullness were assessed at specific times using visual analog scales.Statistical analysesEffect of eating speed on ad libitum energy intake, eating rate (energy intake/meal duration), energy density (energy intake per gram of food and water consumed), and satiety were assessed by mixed-model repeated measures analysis.ResultsMeal energy intake was significantly lower in the normal-weight (804.5±438.9 vs 892.6±330.2 kcal; P=0.04) but not the overweight/obese (667.3±304.1 vs 724.8±355.5 kcal; P=0.18) subjects during the slow vs the fast eating condition. Both groups had lower meal energy density (P=0.005 and P=0.001, respectively) and eating rate (P<0.0001 in both groups) during the slow vs the fast eating condition. Both groups reported less hunger (P=0.01 and P=0.03, respectively), and the normal-weight subjects reported more fullness (P=0.02) at 60 minutes after the meal began during the slow compared with the fast eating condition. There was no eating speed by weight status interaction for any of the variables.ConclusionsEating slowly significantly lowered meal energy intake in the normal-weight but not in the overweight/obese group. It lowered eating rate and energy density in both groups. Eating slowly led to lower hunger ratings in both groups and increased fullness ratings in the normal-weight group at 60 minutes from when the meal began.  相似文献

BackgroundThe eating in the absence of hunger (EAH) experimental paradigm measures intake of highly palatable, highly processed foods when sated. However, no studies have examined EAH in pregnant women.ObjectiveThe objectives were to investigate whether EAH in pregnant women differs by level of food processing and to examine relationships of EAH with hedonic hunger, addictive-like eating, and impulsivity.DesignEAH was assessed in a counterbalanced crossover feeding substudy in which participants completed two free-access eating occasions following a standardized meal during their second pregnancy trimester. Hedonic hunger (Power of Food Scale), addictive-like eating (modified Yale Food Addiction Scale), and impulsivity (Barratt Impulsiveness Scale-15) were assessed by self-report during early pregnancy.Participants and settingData were collected from March 2015 through September 2016 from a subsample of participants (n = 46) enrolled at ≤12 weeks gestation in an observational, prospective cohort study (the Pregnancy Eating Attributes Study) in North Carolina.InterventionParticipants were presented with highly processed and minimally processed foods in two separate assessments.Main outcome measuresEnergy intake (EAH-kcal) and percent consumed (EAH-%) (calculated as 100 × [amount consumed (g) / amount served (g)]) was measured overall and separately for sweet and savory foods.Statistical analyses performedLinear mixed models estimated the effect of condition on EAH. Hedonic hunger, addictive-like eating, impulsivity and their interaction were examined separately.ResultsEAH-% was similar across conditions (16.3% ± 1.1% highly processed vs 17.9% ± 1.2% minimally processed; P = 0.76), resulting in 338.5 ± 34.2 kcal greater energy intake in the highly processed vs minimally processed condition (P < 0.001). Hedonic hunger was not significantly associated with EAH; reward-related eating was positively associated with EAH-kcal and EAH-% of savory foods, and Barratt Impulsivity was positively associated with EAH-kcal and EAH-% overall, and with EAH-% of sweet foods (P < 0.05). There was little evidence of an interaction of Barratt Impulsivity with hedonic hunger or reward-related eating.ConclusionsEAH in pregnant women occurs for both highly processed and minimally processed foods and correlates positively with self-reported addictive-like eating, but not hedonic hunger. Impulsivity did not modify associations of addictive-like eating with EAH in this sample.  相似文献

The aim of the present work was to investigate the effects of eggs consumed for lunch on satiety, satiation and subsequent energy intake at the next meal. Thirty-one healthy male and female subjects participated in a randomized, three-way, crossover study. Following consumption of a standard breakfast, participants were asked to consume three isocaloric test lunches: omelette, jacket potato and chicken sandwich. Subjective measures of satiety were recorded using visual analog scales at regular intervals throughout the day. Energy intake at the next meal was assessed 4 h after lunch with an ad libitum meal. The egg lunch showed a significantly stronger satiating effect compared with the jacket potato meal. No effect on energy intake was seen. These data indicate that consumption of an omelette meal consumed at lunch could increase satiety to a greater extent than a carbohydrate meal and may facilitate reduction of energy consumption between meals.  相似文献

Abstract

Smoothies are a popular breakfast option. However, liquids may evoke weaker satiation than nutritionally comparable semi-solid and solid foods. This study examined consumption of cereal and milk (CM) or a nutritionally comparable fruit smoothie (FS) for breakfast on subsequent dietary behaviours, in a controlled laboratory setting. Twenty-five participants (age 25?±?6?y) completed three trials, receiving either CM or FS for breakfast. Afterwards, participants remained isolated for 4?h with ad libitum access to foods/beverages. A repeat trial (CM or FS) allowed exploration of normal variability. Post-breakfast energy intake (EI) (CM = 1465(2436) vs. FS = 1787(3190) kJ, Median (IQR), p?=?0.099), time to intake of next food/fluid (meal latency) (CM = 146(97) vs. FS = 180(100) min, p?=?0.127), and subjective hunger, desire to eat, fullness and thirst ratings were similar between conditions (p’s?>?0.05). The mean coefficient of variation for EI and meal latency were 41% and 21%, respectively. Consumption of a FS does not negatively impact acute EI and meal latency.  相似文献

Abstract

High sodium intake increases cardiovascular risk by increasing blood pressure. The intake of coffee elevates blood pressure acutely. Preclinical evidence shows that this action of caffeine is enhanced by high salt intake. We hypothesised that high sodium intake augments the acute blood pressure response to coffee in humans. A randomised cross-over study (n?=?15) was performed comparing the effect of lower (6?g/d; LS) with higher (12?g/d; HS) sodium chloride diet on blood pressure before and 2?h after regular coffee intake. Baseline blood pressure was 115?±?4/84?±?2/68?±?1 during LS and 121?±?4/89?±?2/69?±?1?mmHg during HS (SBP/Mean Arterial Pressure (MAP)/DBP; mean?±?SE, p?<?0.05 for SBP). During LS, blood pressure increased to 121?±?4/91?±?2/73?±?1 (p?<?0.05 for SBP, MAP, DBP versus baseline). HS did not significantly affect the impact of coffee on blood pressure (p?>?0.3 for SBP, DBP; p?>?0.05 for MAP). Sodium intake does not relevantly modulate the impact of regular coffee consumption on blood pressure.  相似文献
