The effect on the test behavior of children, as reflected in the I.Q. scores, when reinforced after each correct response.

This experiment studied the effect on intelligence test scores of a probable reinforcer given for correct responses. Eleven pairs of 5- to 7-yr-old children were matched on the basis of a strong liking of candy, no physical problems associated with eating it, parent permission to receive and eat the candy, age, sex, and a revised Stanford-Binet Scale Form L IQ score. The control group was given the revised Stanford-Binet Scale Form M, as prescribed in the test manual. The experimental group was also given Form M according to the manual, except M&M candy was given for each plus or correct response. There was an appreciable, statistically significant difference between the resulting IQ test scores of the two groups.

Effects of choice and immediacy of reinforcement on single response and switching behavior of children.

Children responded on a single operandum to produce marbles or candy within a two-component multiple schedule and then were allowed to choose which component was in effect. Experiment I examined the effects of exchanging marbles after sessions for subject-selected or experimenter-selected candy. Rate of response to the single operandum was not affected. However, when the subjects could switch components, they spent the majority of time and responded at somewhat higher rates in a component where marbles were exchangable for subject-selected candy. Experiment II examined the effects of eliminating the immediate marble consequence for responses. Rate of response to the single operandum was not affected. However, when subjects could switch components they spent more time in a component where immediate marble consequences were available for responses, than where no immediate marble consequences were available.

Exposure of Japanese school children to smoking-related environmental factors.

Japan has no legal restrictions on cigarette advertising and vending machines. This lack of smoking control measures is a possible contributor to smoking initiation by adolescents. This study was conducted to provide primary data on environmental factors related to smoking, such as cigarette advertising and candy cigarettes, that influence elementary school children in Japan. A cross-sectional survey was conducted with a self-administered questionnaire at two elementary schools in Kitakyushu City, Japan in 1995. Questionnaire sheets were anonymously filled out by 282 elementary school children at school. The effective response rate was 91.5% (128 boys and 130 girls). Over 90% of respondents had seen cigarette advertising on TV, candy cigarettes and cigarette vending machines. Over 75% had at least one smoker in their family. Fewer female children expressed an intent to smoke in the future despite the fact that there were no significant sex differences in smoking-related experiences. Children were higher exposed to cigarette advertising on TV, candy cigarettes, vending machines and family members' smoking. Control of such smoking-related factors in the environment would be crucial to keeping children from initiating smoking behavior.

Vero cytotoxin-producing Escherichia coli O157 gastroenteritis in farm visitors, North Wales.

An outbreak of Vero cytotoxin-producing Escherichia coli O157 (VTEC O157) gastroenteritis in visitors to an open farm in North Wales resulted in 17 primary and 7 secondary cases of illness. E. coli O157 Vero cytotoxin type 2, phage type 2 was isolated from 23 human cases and environmental animal fecal samples. A case-control study of 16 primary case-patients and 36 controls (all children) showed a significant association with attendance on the 2nd day of a festival, eating ice cream or cotton candy (candy floss), and contact with cows or goats. On multivariable analysis, only the association between illness and ice cream (odds ratio [OR]=11.99, 95% confidence interval [CI] 1.04 to 137.76) and cotton candy (OR=51.90, 95% CI 2.77 to 970.67) remained significant. In addition to supervised handwashing, we recommend that foods on open farms only be eaten in dedicated clean areas and that sticky foods be discouraged.

Perception of toxicity and dose by 3- and 4-year-old children.

Three and 4-year-old children from two suburban preschools were individually interviewed to assess their knowledge of the effects of ingesting a household product, a candy, and a common drug. Most children understood that scouring cleanser was toxic. Children reported that candy was safe to eat, even in large amounts. However, vitamins were not perceived by all children as having a dose-related toxicity. This understanding developed with age, and boys were better than girls at differentiating between a usual and an excessive dose of vitamins. One overdose occurred, perhaps because of an increase in the child's interest in vitamins after the interview. More research is needed to broaden our understanding of children's knowledge of the toxicity of poisons. The results of the present study provided information needed for the formulation of educational objectives for a preschool poison prevention program. We believe the primary message is that nothing should be eaten unless it is approved by an adult.

Effect of effort on meal selection and meal acceptability in a student cafeteria.

Past laboratory and field studies show that the effort necessary to obtain food acts as a determinant of food selection and consumption. Two studies examined the impact of increasing the effort needed to obtain candy or potato chips on selection in a normal lunch setting. In the first study, food selection, acceptance and intake were obtained during the first week baseline and under the effort manipulation during the second week. With increased effort, candy selection dropped dramatically in week 2. Subjects substituted items from the desert, fruit and accessory food groups. In the second study, food selection and acceptance were measured during a 2-week baseline, a 3-week effort period, and a 3-week recovery period. With increased effort, potato chip selection dropped dramatically and only partially recovered in the last phase. Subjects substituted items from the starch food group. These results demonstrate that changes in the effort needed to obtain food can have a nutritional impact in an actual eating situation and could be an important part of a healthy eating strategy.

Relationship of medical status, medications, and salivary flow rates in adults of different ages.

Multiple systemic disorders and medications have been reported to cause xerostomia or salivary gland hypofunction. The purpose of this study was to evaluate the relationship among systemic disorders, medications, and salivary flow rates. Sixty-three ambulatory dental patients aged 23 to 82 years were randomly selected. The nature, duration, and number of systemic disorders and medications were documented. Repeated measurements of unstimulated whole, chewing-stimulated whole, acid-stimulated parotid, and candy-stimulated parotid salivary flow rates were obtained. Data were analyzed with the Wilcoxon rank-sum test, nonparametric multivariate analysis of variance, and Fisher's exact test. For persons with systemic disorders who were taking medication, all salivary flow rates were significantly (p = 0.03 - 0.001) lower than the flow rates in healthy persons. Among persons with at least one systemic disorder who were taking medication, those who had been taking medication for longer than 2 years had significantly lower unstimulated whole saliva (p = 0.002), chewing-stimulated whole saliva (p = 0.0004), and candy-stimulated parotid saliva (p = 0.02) flow rates than those who had been taking medication for 1 to 2 years. The number of systemic disorders significantly (p = 0.02) and negatively affected the acid-stimulated parotid salivary rates. The prevalence of salivary hypofunction determined on the basis of unstimulated whole saliva and acid-stimulated parotid saliva was significantly higher (p = < 0.001, p = 0.007) in the those persons with systemic disorders and taking medications. The results suggest that salivary secretion is affected by the number of systemic disorders and duration of the potentially xerogenic medications.

Patterns of chocolate consumption.

Although consumed in some form since at least 460 AD, cacao (Theobroma cacao) was not used in confectionery until the 19th century when the cocoa press was invented. Per capita consumption of chocolate confectionery in the United States is moderate (approximately 4.6-4.8 kg/y) compared with that of many northern European countries (approximately 7-10 kg/y). Eleven percent of the US population reported consuming chocolate candy on > or = 1 of the 3 d of recorded food intake in the US Department of Agriculture Nationwide Food Consumption Survey 1987-1988; < 1.0% consumed chocolate every day. The Western region of the United States contained the highest proportion of chocolate consumers. More whites than other racial groups were consumers. Chocolate was consumed by more people in the winter than in other seasons and more was consumed at snacks than at meals. The mean amount of chocolate consumed was approximately 30-90 g/d, depending on sex and age group. Chocolate candy was only a minor contributor (0.7-3.4%) to the overall dietary intake of total energy, fat, saturated fatty acids, and stearic acid.

Heightened sour preferences during childhood.

Basic research has revealed that the chemical sensory world of children is different from that of adults, as evidenced by their heightened preferences for sweet and salty tastes. However, little is known about the ontogeny of sour taste preferences, despite the growing market of extreme sour candies. The present study investigated whether the level of sourness most preferred in a food matrix and the ability to discriminate differences in sour intensity differed between 5- to 9-year-old children and their mothers, by using a rank-by-elimination procedure embedded in the context of a game. Mothers also completed a variety of questionnaires and children were asked several questions to assess whether children's temperament and food preferences and habits related to sour preferences. The results indicated that, although every mother and all but two of the children (92%) were able to rank the gelatins from most to least sour, more than one-third (35%) of the children, but virtually none of the adults, preferred the high levels of sour taste (0.25 M citric acid) in gelatin. Those children who preferred the extreme sour tastes were significantly less food neophobic (P < 0.05) and tended to experience a greater variety of fruits when compared with the remaining children (P = 0.11). Moreover, the children's preference for sour tastes generalized to other foods, such as candies and lemons, as reported by both children and mothers. These findings are the first experimental evidence to demonstrate that sour taste preferences are heightened during childhood and that such preferences are related to children's food habits and preferences. Further research is needed to unfold the relationship between the level of sour taste preferred and the actual consumption of sour-tasting foods and flavors in children.

Turkish pepper (extra hot).

A 38 year old female office worker was admitted with a newly discovered blood pressure of 250/110 mm Hg. Evaluation for secondary forms of hypertension was negative and treatment was begun. Sodium excretion was markedly reduced, plasma aldosterone was normal, and plasma renin activity was low. Therefore, presence of an aldosterone-like activity was suspected. Eventually, the patient confessed to abusing "Turkish Pepper", a brand of Scandinavian liquorice candies and "Fisherman's Friend", another brand of liquorice candies, concurrently. After eliminating liquorice from her diet, the hypertension disappeared thus allowing her antihypertensive treatment to be stopped.

Sugar alcohols: what is the evidence for caries-preventive and caries-therapeutic effects?

The most widely used sugar alcohols are: xylitol, sorbitol, mannitol, maltitol, lactitol and the products Lycasin and Palatinit. It is often claimed that xylitol is superior to the other sugar alcohols for caries control. This paper examines clinical studies on the caries-preventive and therapeutic effects of sugar alcohols with emphasis on sorbitol and xylitol. It is concluded that chewing sugar-free gum 3 or more times daily for prolonged periods of time may reduce caries incidence irrespective of the type of sugar alcohol used. It may be sufficient to do this only on school days. Sucking xylitol-containing candies or tablets may have a similar effect as chewing xylitol chewing gum. Clinical trials suggest greater caries reductions from chewing gums sweetened with xylitol than from gums sweetened with sorbitol. However, the superiority of xylitol was not confirmed in 2 out of 4 clinical trials comparing the caries-preventive effect of xylitol- with sorbitol-sweetened gums. The caries-preventive effects of polyol-containing gums and candies seem to be based on stimulation of the salivary flow, although an antimicrobial effect cannot be excluded. There is no evidence for a caries-therapeutic effect of xylitol. These conclusions are in line with those of recent reviews and with the conclusions of the Scientific Committee on Medicinal Products and Medical Devices of the EU Commission.

Xylitol concentration in saliva and dental plaque after use of various xylitol-containing products.

The study consisted of two sets of experiments, one in saliva and one in dental plaque. The xylitol concentration in saliva was determined enzymatically in 12 children (mean age 11.5 years) after a standardised use of various xylitol products: (A) chewing gums (1.3 g xylitol), (B) sucking tablets (0.8 g xylitol), (C) candy tablets (1.1 g xylitol), (D) toothpaste (0.1 g xylitol), (E) rinse (1.0 g xylitol), and (F) a non-xylitol paraffin. Unstimulated saliva was sampled 1, 3, 8, 16 and 30 min after use. The concentration in dental plaque was determined after mouthrinses with contrasting amounts of xylitol (LX = 2.0 g, HX = 6.0 g, and control) and supragingival plaque was collected and pooled after 5, 15 and 30 min. The mean xylitol concentration in saliva at baseline was approximately 0.1 mg/ml. All xylitol-containing products resulted in significantly increased levels (p < 0.05) immediately after intake and remained elevated for 8-16 min in the different groups. The highest mean value in saliva was obtained immediately after use of chewing gums (33.7 +/- 16.4 mg/ml) and the lowest was demonstrated after using toothpaste (8.2 +/- 4.9 mg/ml). No significant differences were demonstrated between chewing gums (A), sucking tablets (B), candy (C) and rinses (E). In dental plaque, the mean values were 8.6 +/- 5.4 and 5.1 +/- 4.0 mg/ml 5 min after HX and LX rinses. Concerning the higher concentration, the values remained significantly elevated (p < 0.05) during the entire 30-min follow-up. In conclusion, commonly advocated xylitol-containing products gave elevated concentrations of xylitol in unstimulated whole saliva and dental plaque for at least 8 min after intake.

Stepwise prediction of dental caries in children up to 3.5 years of age.

The present study is a part of a prospective, longitudinal investigation of caries development in children (n = 692) living in the southern suburbs of Stockholm. The aim was to evaluate, longitudinally, the caries-predictive ability of variables describing social and immigrant background, dietary habits, microbial and oral hygiene factors, and fluoride exposure in children at 1 and 2.5 years of age with respect to caries development before the age of 3.5. The predictors for caries development in children before 2.5 years of age were mutans streptococci (p < 0.01), immigrant background (p < 0.01), and consumption of candy (p < 0.01). The predictors for developing manifest caries between 2.5 and 3.5 years of age were mutans streptococci (p < 0.001), mother's education (p < 0.001), immigrant background (p < 0.01), and consumption of candy (p < 0.05) and sugar-containing beverages (p < 0.05). The caries incidence at 2.5 years of age as well as the caries increment between 2.5 and 3.5 years of age were significantly higher in children with immigrant background compared to non-immigrants. This study indicates that the possibility of identifying children at risk for caries development increases longitudinally from 1 to 3.5 years of age and there was a synergistic effect between age and each predictor.

How xylitol-containing products affect cariogenic bacteria.

BACKGROUND: The authors examined the effect of xylitol, a naturally occurring sweetener, on levels of Streptococcus mutans and S. sobrinus. They also investigated xylitol's mechanism of action. METHODS: The authors compared cariogenic bacteria levels before and after exposure to xylitol products in children and adults. In the first study, 187 children received xylitol-containing snacks in school for four weeks. In the second study, two adults received xylitol candy for four weeks. Unstimulated saliva samples were taken from all subjects. Gingival samples also were taken from the adults. The authors plated the samples on selective microbiological media. Individual isolates were plated on media with varying concentrations of xylitol, and were identified using specific DNA probes. Genetic relatedness was determined via pulse-field gel electrophoresis. RESULTS: The children's salivary S. mutans levels remained stable before and after xylitol exposure. Further analysis of the S. mutans isolates was conducted for seven children. Bacteria from five of these children grew with 10 percent or less xylitol at baseline, while the bacteria from all seven children grew with 15 percent xylitol after exposure to the xylitol-containing snacks, suggesting that the S. mutans increased in tolerance to xylitol during exposure. Six children had isolates with the same genotype at both time points. S. mutans and S. sobrinus levels were reduced in one of the adults as a result of xylitol exposure, and the bacterial isolates became more xylitol tolerant. In the second adult, S. mutans and S. sobrinus levels increased, while the subject maintained the same proportion of susceptible and tolerant strains as that at baseline. CONCLUSIONS: Overall, consumption of xylitol-containing snacks and candy did not reduce S. mutans levels. However, bacteria from five children and one adult became more xylitol tolerant. CLINICAL IMPLICATIONS: These results provide a basis on which xylitol-containing products can be recommended and xylitol's mechanism of action can be explained to patients.

Determination of polydextrose in foods by ion chromatography: collaborative study.

Eight collaborating laboratories assayed 7 blind duplicate pairs of foods for polydextrose content. The 7 test sample pairs ranged from low (2%) to high (95%) levels. The following foods were prepared with polydextrose mixed into the other ingredients and then baked, cooked, or otherwise prepared: milk chocolate candy, iced tea, sugar cookie, grape jelly, soft jellied candy, and powdered drink mix. Collaborators received a polydextrose standard to develop a calibration curve. The method determined polydextrose by ion chromatography, after removal of interfering food components (high molecular weight solubles). Repeatability standard deviations (RSDr) ranged from 3.93 to 9.04%; reproducibility standard deviations (RSDR) ranged from 4.48 to 14.06%. The average recovery was 94%.

Gas-liquid chromatographic determination of total cholesterol in multicomponent foods.

A method is described for the determination of total cholesterol in multicomponent foods and also other products such as nonfat dry milk, dried whole egg solids, and certain candy bars. The lipid is extracted from the sample by a mixed solvent and saponified. The unsaponifiable fraction which contains the cholesterol and other sterols is extracted with benzene. An aliquot is evaporated to dryness and the residue is dissolved in dimethylformamide. The sterols are derivatized to form trimethylsilyl (TMS) ethers. The TMS-cholesterol derivative is quantitatively determined by gas-liquid chromatography, using 5alpha-cholestane as an internal standard. Nine laboratories participated in a collaborative study of the determination of total cholesterol in deviled ham sandwich spread, vegetable beef stew, corned beef hash, frozen chicken pot pie, pizza pepperoni, fish sticks, breaded shrimp, chocolate-covered candy bars, dried whole egg solids, and nonfat dry milk and the results are reported here. The coefficient of variation ranged from 5.64 to 23.2%, with an average coefficient of variation of 14.8%.

Head movements in the occlusal phase of mastication.

It has been recognized that mandibular movements evoke head movements during jaw tapping. However there have been only a few studies that investigated the aspects of head movements during mastication. The objective of this study was to demonstrate the hypothesis that the head moves actively in mastication in order to achieve effective destruction of a food bolus. Head and mandibular movements during gum, gummi candies and kelp chewing among nine adult volunteers have been recorded as time series data with a three-dimensional motion capture system and the vertical components of the movements have been analyzed. To focus on occlusal phase of mastication, the following parameters have been examined: time lag of the head movements at the beginning of occlusal phase, perpendicular velocity of the head at the beginning of the phase of occlusion, and average velocity of the head during occlusal phase. The results showed that the head moved downward in mastication and the velocity of the head movements increased in the order of gum, gummi candies and kelp chewing. There is a possibility that the elasticity of a food bolus affects the activity of head movements, and the kinetic energy was increased to achieve effective destruction of a food bolus.

[Epidemiology of caries in Alicante preschoolers. 2. Risk factors].

An epidemiological study of dental caries amongst preschoolers (aged between 4 and 6 years) from the city of Alicante has been carried out. The influence of the socioeconomic class as well as higienic and diet habits on the appearance dental caries of deciduous teeth has been evaluated. From a total population 7,289 preschoolers, a representative sample of 1,292 children was obtained by the sampling process of a stratified randomization. A statistical significant association was found between socioeconomic class and dental caries (p less than or equal to 0.05), being the lower classes the more prone to dental caries. Higienic habits of the examined children were clearly inadequate; 75.62% of preschoolers showing dental plaque. There was a statistical significant relationship between dental plaque and caries (p less than or equal to 0.05). The ingestion of candies has been shown to be also related with dental caries. Those children who never eat candies showed a prevalence of dental caries of 30.84%, whereas the prevalence increased up to 44% in cases of frequent ingestion of sugared food.
