Television viewing and snacking.

With the rise in obesity in America, the search for potential causes for this epidemic has begun to include a focus on environmental factors. Television (TV) viewing is one such factor, partially due to its potential as a stimulus for eating. The current study investigated the relationship between food intake and self-reported TV viewing in an effort to identify the impact of TV viewing on specific eating behaviors. Seventy-four overweight women seeking obesity treatment completed questionnaires assessing dietary habits and TV viewing behaviors. Results suggest that snacking, but not necessarily eating meals, while watching TV is associated with increased overall caloric intake and calories from fat. Therefore, interventions targeting stimulus control techniques to reduce snacking behavior may have an impact on overall caloric intake.

The effect of social demographic factors, snack consumption and vending machine use on oral health of children living in London.

OBJECTIVE: To investigate the effect of socio-economic status, sugar, snack consumption and vending machine use on the prevalence and severity of caries (DMF) in children. DESIGN: An observational study was carried out in a dental practice in inner city London. Sixty children were asked to complete a questionnaire and a three day food and drink diary. After a dental examination the number of decayed (D), missing (M) or filled (F) teeth provided a DMF score. Anova and Pearsons correlations were used to analyse the data statistically. RESULTS: Children from social groups I and II consumed significantly less (P < 0.05) sugar, confectionery, crisps and used a vending machine less often than children from other social groups. Children from Social groups I, II and III had significantly lower DMF scores. The average DMF from social group I children was 0.5 +/- 0.6, whilst group IV children had the greatest incidence and a DMF of 4.6 +/- 0.8. Significant correlations were identified between DMF and sugar, confectionery and crisp consumption and vending machine use, and a negative correlation between DMF and vegetable consumption. CONCLUSIONS: Socio-economic status and access to vending machines were found to have a significant effect on sugar intakes, foods choices, and dental health. The removal of vending machines from schools or at least installing 'healthy' vending machines is recommended. Health promotion programmes that account for social groups and snacking habits that are cost effective are required.

The global obesity epidemic: snacking and obesity may start with free meals during infant feeding.

UNLABELLED: Feeding is vital for survival. The brain has strong hunger and reward mechanisms that ensure optimal food intake for adequate nutrition. The drive for feeding is particularly strong in humans whose large brains require large energy support. This starts immediately after birth; the newborn child being able to taste sucrose and suck the sweet and fat from its mother's milk. At present, mothers are generally advised to breastfeed children as often as they like, which may be up to 15 times a day. At the same time, childhood obesity is rapidly developing. One reason for the rapidly increasing prevalence of childhood obesity may be overfeeding with snack food. CONCLUSION: We hypothesize that non-rule breastfeeding favours the development of snacking throughout the day during childhood, a habit which in turn favours the development of obesity.

The use of iodised salt in the manufacturing of processed foods in South Africa: bread and bread premixes, margarine, and flavourants of salty snacks.

Salt is widely used by the food industry, but information on the use of iodised salt as an ingredient in the manufacturing of processed foods in South Africa is not available. The iodine content of salt used in the manufacturing of bread, margarine and salty snack flavourants was investigated in a cross-sectional descriptive study. Questionnaire information and salt sampled on 1 day per week for 5 consecutive weeks were obtained from 12 food manufacturers (eight bread and bread premix manufacturers, two margarine manufacturers and two salty snack flavourant manufacturers). The iodine concentration of salt samples was analysed using the potentiometric titration method. Eleven of the 12 manufacturers surveyed reported that they used non-iodised salt. The reported reasons for using non-iodised salt included properties of the final product, health reasons, and financial considerations. However, substantial amounts of iodine were found in the salt of one-third of these manufacturers (n = 4), ranging from a mean content of 39-69 ppm. Three of these four particular manufacturers distributed their products countrywide. This information serves as a strong indication that iodised salt does not necessarily cause the adverse affects that food manufacturers fear may affect their products. Although the amounts of iodine in the salt were variable, our results showed that an appreciable percentage of the food companies used iodised salt unknowingly in the manufacturing of frequently consumed processed foods, and this may have a considerable impact on the daily iodine intake of consumers.

Sweets, snacks, and dental caries: South African interracial patterns.

Sucrose has been thought to cause dental caries; sweets and snacks being primarily responsible, together with plaque and their respective interactions. Dietary questionnaires revealed that in 3 to 5 yr olds, protein in black, colored, Indian, and white groups provided 12 to 15% of total intake, fats 10 to 17%, and carbohydrates 69 to 78%. At 16 to 17 yr old, patterns remained essentially similar. Sucrose provided about one-quarter of intake, sweets and snacks less than one-tenth, but dental caries prevalence increased rapidly from black to white. This raised several questions regarding current concepts of caries causation. Are genetic, immunological and other dietary factors also responsible for caries levels experienced?

Exercise Snacks Are Feasible to Perform in the Real World and Improve Physical Capacity for Adults Living With Non-Insulin Treated Type 2 Diabetes: A Randomised Trial.

AIMS: To investigate the feasibility and preliminary efficacy of a 12-week remotely-delivered exercise snacks (ES) intervention in adults with type 2 diabetes. MATERIAL AND METHODS: Insufficiently active adults with type 2 diabetes (N = 69; 46 females; mean age ± SD: 58 ± 11 years) were randomised to an ES or mobility/stretching comparator group (CON), which involved 4 × 1-min bouts of either vigorous or low intensity exercise, respectively, on ≥ 5 days/week. The primary outcome was feasibility based on adherence. Secondary outcomes included exercise enjoyment (1-7 scale), rating of perceived exertion (RPE; 0-10 scale), heart rate (HR), haemoglobin A1c (HbA1c), blood biomarkers of cardiometabolic health, 30-s sit-to-stand capacity, grip strength, estimated maximal oxygen uptake, and anthropometrics. RESULTS: Weekly adherence (estimated marginal mean [95% confidence interval]: 18 bouts [16-21] for both groups; p = 0.99) and total enjoyment (ES: 4.5 [4.1-4.8] vs. CON: 4.3 [4.0-4.7]; p = 0.64) were high and not different between groups. Despite higher RPE (5.7 [5.4-6.1]) and peak HR (73 [70-77] % of age-predicted HR maximum) in ES versus CON (2.0 [1.7-2.4] and 61 [58-64] % of age-predicted HR maximum, respectively) (all p < 0.001), there were no between-group differences in the change in any secondary outcome (all p > 0.05) except for greater sit-to-stand capacity in ES after training (between-group effect estimate [95% confidence interval]: 1.9 repetitions [0.3-3.4]; p = 0.02). CONCLUSIONS: Exercise snacks were feasible to perform in the real world and improved sit-to-stand capacity to a greater extent than CON in adults living with type 2 diabetes. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT06407245.

Food for thought or thought for food?--a stakeholder dialogue around the role of the snacking industry in addressing the obesity epidemic.

The current obesity epidemic is generally considered multi-causal. Certain foods, including snacks such as potato chips, and their marketing are often highlighted as needing particular attention. This forces potato chip producers to take position on their role and responsibility. Based on expert interviews and a literature review, a systems analysis approach is presented that distinguishes between basic physiology, self-control and what we call jam transmitters, signals and pressures from the environment that hinder or frustrate self-control. Examples of the latter are commercial push and seduction, obesogenic cultures, obesogenic physical environment, socioeconomic factors, genes, hormones and instincts. Solution of the epidemic demands an approach that involves all factors and all related actors. As for the snacking industry, the comprehensive responses are: to introduce specific diet products; to improve the nutritional quality of its products; the latter combined with supporting and engaging in healthy lifestyle marketing; to practice responsible targeting of marketing; and to limit the promotion of unhealthy consumption patterns.

Dental caries in South African black and white high school pupils in relation to sugar intake and snack habits.

DMFT scores, total sugar intakes and snacks habits were determined in 1918 South African Black pupils (923 rural, 995 urban) and 724 White pupils (English and Afrikaans speaking) aged 16-18 years inclusive. Mean DMFT scores of school groups of Black pupils (both sexes) ranged from 0.9 and 2.0 in rural areas, to 4.2-6.7 in urban areas (where data were far higher than such obtained 7 years ago), and were 9.2 and 10.2 for White pupils. Corresponding mean daily sugar intake were - rural Blacks, 69 g and 97 g, urban Blacks 118-141 g, respectively (all slightly higher than previously); and Whites 102 g and 123 g. Mean DMFT scores of girls were higher than those of boys; yet while mean sugar intakes of Blacks girls and boys were somewhat similar, White girls' intakes were much lower than those of White boys. In the ethnic-sex groups studied, mean DMFT scores for pupils in upper, compared with lower, third of sugar intake, were higher in nine of the 14 sub-groups. Mean DMFT scores in upper, compared with lower, third of exposure to snack practices were higher in 11 of the 14 groups. However, most of the differences were slight. In further research, more intensive enquiries should be pursued on roles of ethnic and familial factors, as well as on roles of inter-acting dietary components additional to sugar and sugar-containing foods.

Snack food consumption of 12 year old inner-city children and its relationship to oral health.

The relations between reported frequency of consumption of 18 common snack foods, SES variables, and oral health scores were studied in 92 12-year-old children from three inner-city schools in Rochester, New York. The group was composed of 44 males and 48 females who were either black or had a Spanish surname. The study documented only a few significant relations between consumption of snack foods and DMF scores or overall oral health. Reported cake consumption correlated positively with total debris and gingivitis, and consumption of chewy candy and ice cream was positively related to DMF scores. Black females exhibited the greatest number of decayed and DMF teeth, and both male and female black children had significantly greater amounts of total debris, gingivitis and decayed teeth.

Effects of preexercise snack feeding on endurance cycle exercise.

We studied the effects of ingesting either a snack food (S) (260 kcal) or placebo (P) 30 min before intermittent cycle exercise at 70% maximal O2 consumption on endurance performance and muscle glycogen depletion in eight healthy human males. Immediately before exercise there were significantly greater increases in plasma glucose (PG) (S +28 +/- 9.7; P +0.1 +/- 0.8 mg/dl) and insulin (S +219 +/- 61.5; P -7 +/- 5.5 pmol/l) (P less than 0.05) following S feeding compared with P. These differences were no longer present by the end of the first exercise period. There were no differences in endurance times (S 52 +/- 6.4; P 48 +/- 5.6 min) or in the extent of muscle glycogen depletion following exercise (S 56 +/- 14.7; P 50 +/- 15.5 micrograms/mg protein) between the two groups. PG was maintained at base-line (prefeeding) concentrations following S, whereas there was a tendency for PG to steadily decrease after P. Total grams of carbohydrate oxidized during exercise did not differ between the two groups (S 120; P 118 g). These results demonstrate that the ingestion of a mixed-macronutrient snack 30 min before exercise does not impair endurance performance nor increase the extent of muscle glycogen depletion during high-intensity cycle exercise in untrained adult male subjects.

Aspiration of fruit gel snacks.

Aspiration of a foreign body is common in children and can cause upper airway obstruction, leading to significant morbidity or mortality. We report 3 cases of aspiration of a popular fruit-flavored gel snack that led to cardiopulmonary arrest and death in 1 case and respiratory failure in 2 other cases. There is increasing concern about the safety of this gel snack and its risk of aspiration, even in older children. Pediatricians should advise parents and children about the dangers of eating this candy during their health maintenance visits.

Assessment of stimuli controlling the requests of students with severe mental retardation during a snack routine.

This study assessed stimuli controlling requests during a snack routine after extensive request training with a delayed prompt procedure. During training sessions, one of three three-item snack groups was presented to 3 subjects with severe mental retardation. Assessment sessions involved (a) training conditions (all items were visible), (b) presenting two of three items from a particular group, or (c) presenting no items. One subject requested food items when no food items were present, 2 frequently requested a missing item when the two other items were visible, and all subjects requested visible items. Procedures for assessing stimulus control, such as those described in the current paper, should lead to a better understanding of the variables controlling behaviors that initially appear perplexing and unpredictable.

Gastrointestinal symptoms in 3181 volunteers ingesting snack foods containing olestra or triglycerides. A 6-week randomized, placebo-controlled trial.

BACKGROUND: Olestra is a nonabsorbable, energy-free fat substitute. Because it is not absorbed, it may cause digestive symptoms when consumed in large amounts. OBJECTIVE: To compare the frequency and impact of gastrointestinal symptoms in adults and children who freely consume snacks containing olestra or regular snacks in the home. DESIGN: 6-week, double-blind, randomized, parallel, placebo-controlled trial. SETTING: General community. PARTICIPANTS: 3181 volunteers 2 to 89 years of age. INTERVENTION: Households received identical packages labeled as containing olestra corn or potato chips. These packages contained either olestra or regular chips (control). MEASUREMENT: Gastrointestinal symptoms and their impact on daily activities were reported in a daily record. RESULTS: At least one gastrointestinal symptom was reported by 619 of 1620 (38.2%) persons in the olestra group and 576 of 1561 (36.9%) controls (difference, 1.3 percentage points [95% CI, -3.6 to 6.2 percentage points]; P = 0.60). In general, the groups did not differ significantly in the proportion of participants who reported individual gastrointestinal symptoms; however, more controls reported nausea (8.4% compared with 5.7%; difference, -2.7 percentage points [CI, -4.9 to -0.4 percentage points]; P = 0.02). The only difference between groups for the mean numbers of days on which symptoms were reported was that participants in the olestra group had 1 more symptom-day of more frequent bowel movements than did controls (3.7 symptom-days compared with 2.8 symptom days; difference, 0.9 symptom-days [CI, 0.1 to 1.8 symptom-days]; P = 0.04). The groups did not differ in the impact of symptoms on daily activities. CONCLUSIONS: Clinically meaningful or bothersome gastrointestinal effects are not associated with unregulated consumption of olestra corn and potato chips in the home.

[Children's eating habits at breakfast and snacks between meals (author's transl)].

Detailed inquiries into the eating habits of 86 children attending schools and kindergartens was carried out and a nut-nougat cream spread was evaluated in a 14-day investigation. The selection of food for the snacks requires some correction according to these results e. g. for salt biscuits, sweets, soft drinks. 22% of the parents still compel their children to eat everything up, more than 1/3 leave the purchase of snacks to the children. The nut-nougat cream enjoys enormous popularity as a spread for bread so that even large food undertakings cannot face this development with equanimity. From the nutritional physiology aspect this product is only to be considered positively if spreading of any fat under it can be avoided -- a question of explanation and education, because only then will a superfluity of calories be prevented.

Do snacks of exercise lower blood pressure? A randomised crossover trial.

AIM: To assess whether four 10-minute 'snacks' of exercise per day are as effective at lowering blood pressure as 40 minutes of continuous moderate exercise, when compared with no exercise. METHOD: Single blind randomised crossover trial of three 'exercise' regimes in general practice. PARTICIPANTS: 35 hypertensive adults without complications. INTERVENTIONS: Regimes included 4x10-minute episodes of brisk walking per day, 40 minutes continuous brisk walking per day, and no brisk walking. Each regime lasted 4 days with 10 days of no exercise in between. OUTCOMES: Change of systolic and diastolic blood pressure. RESULTS: Mean age 53 years and mean baseline blood pressure 166/103 mmHg. Systolic blood pressure changed by: -7.5 mmHg (95%CI: -8.9, -6.0) with 40-minutes regime; -7.3 mmHg (95%CI: -8.7, -5.8) with 4x10-minutes regime; and +1.0 mmHg (95%CI: -0.4, 2.5) with 'no brisk walking' regime (p<0.001). Diastolic blood pressure reduced by -4.0 mmHg (95%CI: -5.0, -3.0) with 40 minutes regime; -5.4 mmHg (95%CI: -6.4, -4.4) with 4x10 minutes regime; and -0.2 mmHg (95%CI: -1.2, 0.8) with 'no brisk walking' regime (p<0.001). CONCLUSION: Four 10-minute snacks of brisk walking were as effective as 40 minutes of continuous brisk walking per day at reducing blood pressure. This has implications for public health messages and advice to patients with hypertension.

[Microbiological in vitro and animal experiments assessing the cariogenic potential of various snacks].

Microbiological in vitro and animal experiments were performed to determine the cariogenic potential of different snacks. The determination of the oral salivary sugar clearance time by the aid of a cariogenic S. mutans strain as standard for the cariogenic potential resulted in a relatively high clearance time when a praline was consumed, according to a high cariogenic potential. When consuming a "safe for teeth"-product no easily fermenting substances in the saliva can be shown, suggesting a lacking cariogenic potential. The cariogenic potential of banana, milk-chocolate, Milchschnitte, Müsli-Frucht-Schnitten (cereals and fruits) is between that of the praline and the "safe for teeth"-product. The animal experiments showed in increasing strength of fissure caries after programmed feeding of the following snacks: Basic-diet----milk-chocolate----positive control-diet/Milchschnitte Müsli-Frucht-Schnitten----banana. The highest caries values occurred after having fed banana, the lowest after having fed milk-chocolate. Milchschnitte and Müsli-Frucht-Schnitten showed similar caries values which were between the values after feeding of milk-chocolate and banana.

Comparison of the glycaemic effect of fructose, sucrose and starch-containing mid-morning snacks in insulin-dependent diabetics.

Capillary blood glucose levels were measured every 30 min for 2 h after four different 20 g carbohydrate mid-morning snacks of foods containing predominantly fructose, sucrose or starch in eight insulin-dependent diabetics and eight normal control subjects. In the diabetic subjects, there was no significant difference in the glycaemic effect of the four different snacks. This study does not support the view that fructose is a useful alternative sweetener for diabetics or the view that sucrose should be excluded from the diet of insulin-dependent diabetics.

Use of sweet snacks, soft drinks and fruit juices, tooth brushing and first dental visit in high DMFT 4-6 year olds of Riyadh region.

A total of 68 children, 4-6 years old and equally distributed by gender were selected for the study. Information about use of sweet snacks, soft drinks and fruit juices/drinks, tooth brushing/cleaning, and first dental visit of the children was obtained through a self-administered questionnaire completed by the parents of the selected children. Sixty (88.2%) children were given sweetened snacks. Fifty one (75%) children were using canned soft drinks and packed fruit juices. Twenty eight (41.2%) children were not brushing/cleaning their teeth. The mean age of first dental visit among the study children was 63 (S.D 16.9) months. It may be concluded that the lack of dietary discipline and good oral hygiene habits were most probably responsible for caries in these children.
