Doctrinal considerations for fast-food obesity suits.

Lawsuits brought by obese plaintiffs against fast-food chains have been the subject of some derision in the late-night talk shows and popular press, and have not succeeded so far. But the common law tort theories on which such lawsuits should be grounded are straightforward, unremarkable, and mainstream. This article first offers an overview of obesity-related health problems that can arise from fast-food diets. It then critiques the seminal Pelman v. McDonald's--how it was pleaded and how it should have been pleaded--and offers alternative legal theories under which such lawsuits can be brought in the future.

Acculturation, physical activity, and fast-food consumption among Asian-American and Hispanic adolescents.

Previous studies have implicated acculturation to the US as a risk factor for unhealthy behaviors among Hispanic and Asian-American adolescents, including substance use, violence, and unsafe sex. This study examined the association between acculturation and obesity-related behaviors-physical activity and fast-food consumption-among 619 Asian-American and 1385 Hispanic adolescents in Southern California. Respondents completed surveys in 6th and 7th grade. The 6th grade survey assessed acculturation with the AHIMSA acculturation scale and a measure of English language usage. The 7th grade survey assessed frequency of moderate-to-intense physical activity and frequency of eating fast-food. Multiple regression analyses included acculturation and demographic covariates as predictors of physical activity and fast-food consumption. Acculturation to the US, assessed in 6th grade, was significantly associated with a lower frequency of physical activity participation and a higher frequency of fast-food consumption in 7th grade. The significant associations persisted after controlling for covariates and were consistent across gender and ethnic groups. Results suggest that acculturation to the US is a risk factor for obesity-related behaviors among Asian-American and Hispanic adolescents. Health promotion programs are needed to encourage physical activity and healthy diets among adolescents in acculturating families.

Body mass index gain, fast food, and physical activity: effects of shared environments over time.

OBJECTIVE: The magnitude of environmental vs. genetic effects on BMI, diet, and physical activity (PA) is widely debated. We followed a sibling cohort (where individuals shared households in childhood and adolescence) to young adulthood (when some continued sharing households and others lived apart) to examine the role of discordant environments in adult twins' divergent trends in BMI and health behaviors and to quantify the variation in BMI and behavior among all siblings that is attributable to environmental and additive genetic effects. RESEARCH METHODS AND PROCEDURES: In the National Longitudinal Study of Adolescent Health, siblings sharing households for > or =10 years as adolescents (mean age = 16.5 +/- 1.7 years; N = 5524) were followed into adulthood (mean = 22.4 +/- 1.8 years; N = 4368), self-reporting PA, sedentary behavior, and dietary characteristics. Adult BMI and adolescent z scores were derived from measured height and weight. RESULTS: Compared with those living together, twins living apart exhibited greater discordance in change in BMI, PA, and fast food intake from adolescence to adulthood. Adolescent household environments accounted for 8% to 10% of variation in adolescent fast food intake and sedentary behaviors and 50% of variation in adolescent overweight. Adolescent household effects on PA were substantially greater in young adulthood (accounting for 50% of variation) vs. adolescence. Young adult fast food intake was significantly affected by young adult household environment, accounting for 12% of variation. DISCUSSION: These findings highlight important environmental influences on BMI, PA, and fast food intake during the transition to adulthood. Household and physical environments play an important role in establishing long-term behavior patterns.

Heterocyclic amine content in fast-food meat products.

Heterocyclic aromatic amines are sometimes formed during the cooking of muscle meats, and their mutagenic and carcinogenic effects are of potential concern in the aetiology of human cancer. In a large survey of the heterocyclic amine content of foods, fried or charbroiled hamburgers, fried chicken, chicken breast sandwiches, fish sandwiches and breakfast sausages were purchased from fast-food restaurants. At least three different chains were visited per product and samples from five stores from each chain were pooled. The solid-phase extraction and HPLC method was used to analyse pooled samples for heterocyclic amine content and mutagenic activity with the Ames/Salmonella assay. Samples were analysed in a blind study which also contained quality control samples of two types, one high and one low in heterocyclic amine content and mutagenic activity. Results from the fast-food products showed undetectable levels of heterocyclic amines in 10 of 17 samples and only low levels [< or = 1 ng/g total of 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx), 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) and 2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (DiMeIQx)] in the remaining samples. Compared with literature values based primarily on laboratory and home cooking conditions, fast-food meat products appear to contribute only a small percentage of the estimated daily dietary intake of heterocyclic amines.

The impact of chewing sugarless gum on the acidogenicity of fast-food meals.

The objective of this study was to evaluate the effect of chewing sorbitol gum on plaque pH following the ingestion of acidogenic fast-food meals. Plaque pH response was monitored using an indwelling wire-telemetry system in five adult panelists. From a pilot study with 12 fast-food meals, the most acidogenic breakfast, lunch and dinner were selected for this study. In the first test, the fasted, resting plaque pH was recorded for 5 minutes; panelists ingested the selected meals for 10 minutes, rinsed thoroughly with 50 ml of tap water, and the pH response was monitored for the remainder of a 2-hour period. In the second test series, the same procedures were followed through the post-meal ingestion rinse. After the pH response to the meal was monitored for 5 minutes, the panelists chewed a sorbitol gum for 15 minutes in their usual manner and the panelists were encouraged to move the gum around their mouth, however, it appeared as if they favored the side of their mouth without the partial denture. The pH response was monitored for the balance of the 2-hour period. All panelists ate the test foods, with and without the chewing gum, according to a randomized-block test design. The results indicated that the use of sorbitol gum significantly raised the plaque pH, prevented the subsequent pH drops after the fast-food meal ingestion and reduced the pH curve area under 5.5.

Effect of fast-food Mediterranean-type diet on type 2 diabetics and healthy human subjects' platelet aggregation.

OBJECTIVE: The aim of our work was to carry out a randomized clinical trial with a fast-food Mediterranean type diet rich in platelet activating factor (PAF) antagonist to investigate the effect on type 2 diabetics and healthy human subject's platelet aggregation. RESEARCH DESIGN AND METHODS: We extracted lipids from fast-food Mediterranean type foodstuffs, and tested them in vitro for their ability to inhibit or antagonize PAF towards washed rabbit platelets. We chose the foodstuffs that exerted the most potent in vitro anti-PAF activity and fed 22 healthy (group A) and 23 type 2 diabetics (group B) subjects on a diet containing the chosen foodstuffs. The 22 type 2 diabetics (group C) subjects were kept on their regular diet that was being followed before entering the study. Before and after a 4-week diet, all enrolled subjects underwent the following examinations; measurement of total cholesterol, low density lipoprotein (LDL-cholesterol), high density lipoprotein (HDL-cholesterol), triglycerides, glucose, HbA(1c), body mass index (BMI), and platelet aggregation in response to PAF, adenosine 5' diphosphate (ADP) and arachidonic acid (AA). RESULTS: The chosen diet significantly increased the EC(50) values of PAF and ADP to groups A and B (p<0.05). No statistical difference was observed on the EC(50) value of group C. No statistical differences were detected among Cholesterol, LDL-cholesterol, triglycerides, glucose, HBA(1c), BMI, and EC(50) for AA values, for any of the three groups. CONCLUSIONS: Consumption of a fast-food Mediterranean type diet rich in PAF antagonist improved platelet response of type 2 diabetics and healthy human subjects against thrombotic, inflammatory and proatherogenic factors.

Adolescent occupational injuries in fast food restaurants: an examination of the problem from a national perspective.

Work injuries to adolescents are most prevalent in the retail trades industry, with a large portion occurring in eating and drinking establishments (E&DEs). Data from the National Electronic Injury Surveillance System were examined for nonfatal injuries to adolescents, ages 14 through 17, injured while working in fast food restaurants (a subcategory of E&DEs) from July 1, 1992, to June 30, 1994. There were an estimated 44,765 adolescent injuries in E&DEs, with an estimated 27,997 in fast food restaurants, during this period. The injury rate for E&DEs in the 15 through 17 age group was higher than for all other industries combined (rate ratio [RR] = 1.7), with little disparity in rates between the sexes. This study identifies the fast food industry as the source of a large proportion of occupational injuries to adolescents, and indicates that task-specific risk factors seem to be strongly related to sex.

Adolescent calorie/fat menu ordering at fast food restaurants compared to other restaurants.

OBJECTIVE: Childhood and adolescent obesity is an increasing public health problem. Fast food consumption has been linked to obesity. The purpose of this study is to determine adolescent calorie and fat consumption patterns at different types of restaurants. METHOD: Study subjects (104 adolescents) were asked to order a dinner meal from 10 restaurant menus with an estimate of how much they would actually consume. A paired T-test was used to compare the calories and fat values for each restaurant vs. McDonald's. RESULTS: Mean calories/fat (g) ordered at each restaurant were: California Pizza Kitchen (CPK).: 1284/70, Chili's (Ch). 1333/62, Denny's (Den): 1226/61, McDonald's (MD): 1016/45, Outback Steakhouse (OS): 1656/93, Panda Express (PE): 873/29, Red Lobster (RL): 1016/49, Stuart Anderson's (SA). 1058/52, Taco Bell (TB): 800/34, Wendy's (Wen): 879/32. Calorie/fat content of the ordered items were significantly higher at CPK, Ch, Den, and OS compared to McDonald's. RL and SA were not significantly different from MD. Calorie/fat content of the ordered items were significantly lower at PE, TB and Wen compared with McDonald's. CONCLUSION: More calories/fat were ordered at many sit down restaurants compared to McDonald's. The lowest calories/fat were ordered at other fast food restaurants (Taco Bell, Wendy's and Panda Express).

An outbreak of Salmonella enteritidis infection at a fast-food restaurant: implications for foodhandler-associated transmission.

An outbreak of Salmonella enteritidis infection occurred in patrons and employees of a fast-food restaurant. Transmission took place over a 9-day period. A single employee (employee A) was identified who had onset of gastrointestinal illness 1 day before the first reported patron exposures and had S. enteritidis isolated from stool. A case-control study of 37 ill and 20 healthy patrons who ate during shifts worked by employee A demonstrated that curly-fried potatoes and ice (odds ratio [OR], 6.8; 95% confidence interval [CI], 1.5-33.7; P = .007), both food items handled bare-handed by employee A, were associated with illness. Employees who worked two or more shifts with employee A were more likely to be infected than those who did not work with employee A (OR, 4.4; CI, 1.0-19.5; P = .03). Foodhandlers who subsequently became infected apparently contaminated multiple food items with additional transmission to patrons. This outbreak illustrates the potential for foodhandlers in a fast-food restaurant setting who are infected with Salmonella to be a source of transmission.

Contamination levels and congener distributions of PCDDs, PCDFs and Co-PCBs in several fast foods in Japan.

We determined the concentrations of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and coplanar polychlorinated biphenyls (Co-PCBs) in three types of fast foods [(1) seventeen hamburgers and two hot dogs, (2) six portions of fried potatoes and (3) three chicken products] obtained from fast food shops or convenience stores in Japan. All samples tested showed low toxic equivalent quantity (TEQ) levels of dioxins in the range of 0.001-0.083 pg-TEQ/g wet weight (0.006-0.053 pg-TEQ/g for hamburgers and hot dogs, 0.001-0.083 pg-TEQ/g for fried potatoes and 0.053-0.065 pg-TEQ/g for chicken products). The congener profile in hamburgers and hot dogs suggested that the total TEQ was mainly determined by Co-PCBs, especially by 3,3',4,4',5-PeCB (#126), which accounted for 44% of the total TEQ value. Findings for animal foods such as beef and cheese were consistent with this result. For fried potatoes, PCDD/Fs accounted for 94% of the total TEQ value, and 2,3,4,7,8-PeCDF accounted for 32% of PCDD/Fs. Dioxins in the chicken products consisted of 3,3',4,4',5-PeCB (#126) and 1,2,3,7,8-PeCDD, which accounted for 23% and 21% of the total TEQ, respectively. If an adult (50 kg weight) eats 150 g of hamburger, 100 g of potatoes and 150 g of chicken, the daily intake is estimated to be 0.299 pg-TEQ/kg b.w./day using the average values (0.022, 0.028 and 0.059 pg-TEQ/g, respectively) obtained in this study. This value corresponds to 7.5% of the tolerable daily intake (TDI) for PCDD/Fs and Co-PCBs in Japan.

Fat content of chips, quality of frying fat and deep-frying practices in New Zealand fast food outlets.

OBJECTIVES: To collect baseline data on the fat content of hot chips, quality (degradation) of cooking fat, deep-frying practices and related attitudes in fast food outlets in New Zealand. To identify the key determinants of the fat content of chips and quality of cooking fat. METHODS: A nationally representative sample of fast food outlets (n=150, response rate 80%) was surveyed between September 1998 and March 1999. Data collected included a questionnaire, observation of cooking practices and analysis of cooked chips and frying fat. RESULTS: Only 8% of independent operators had formal training in deep frying practices compared with 93% of chain operators. There was a wide range of fat content of chips (5%-20%, mean 11.5%). The use of thinner chips, crinkle cut chips and lower fryer fat temperature were associated with higher chip fat content. Eighty-nine per cent of chain outlets used 6-10 mm chips compared with 83% of independent outlets that used chips > or = 12 mm. A wide range of frying temperatures was recorded (136-233 degrees C) with 58% of outlets frying outside the reference range (175-190 degrees C). As indices of fat degradation, fat acid and polar compound values above the recommended levels occurred in 54% and 5% of outlets respectively. Operators seemed willing to learn more about best practice techniques, with lack of knowledge being the main barrier to change. CONCLUSIONS AND IMPLICATIONS: Deep frying practices could be improved through operator training and certification options. Even a small decrease in the mean fat content of chips would reduce the obesogenic impact of this popular food.

Neighbourhood fast food environment and area deprivation-substitution or concentration?

It has been hypothesised that deprived neighbourhoods have poorer quality food environments which may promote the development of obesity. We investigated associations between area deprivation and the location of the four largest fast-food chains in Scotland and England. We found statistically significant increases in density of outlets from more affluent to more deprived areas for each individual fast-food chain and all chains combined. These results provide support for a 'concentration' effect whereby plausible health-damaging environmental risk factors for obesity appear to be 'concentrated' in more deprived areas of England and Scotland.

Brief report: Disposable income, and spending on fast food, alcohol, cigarettes, and gambling by New Zealand secondary school students.

We describe self-reported sources of income and expenditure, and the association between part-time employment and spending on fast food, alcohol, cigarettes, and gambling for a sample of 3434 New Zealand (NZ) secondary school students (mean age 15.0 years). Disposable income was usually received from parents and guardians, but nearly 40% of students also reported receiving money from part-time employment. The proportion of students employed increased as socioeconomic rating increased, and was associated with increased purchasing of fast food and alcohol, and increased spending on cigarettes and gambling. Spending by youth has obvious public health implications, particularly when it is concentrated on products that have a negative health impact.

Grease burns at fast-food restaurants. Adolescents at risk.

Intermountain Burn Center and Utah State Insurance Fund industrial records were reviewed to determine the incidence and consequences of grease burns among teenagers employed at fast-food restaurants. Burn center records reveal that 10 patients were admitted between 1977 and 1985, and that nine patients required surgery with mean burn care costs of $7389 per patient. State Insurance Fund records demonstrate that 81 grease-burn injuries were reported from 1982 through 1985, at an average burn care cost of $660 per patient. Causes of burn wounds included adding, filtering, or removing hot grease, dropping objects into hot grease, slipping on the floor, cleaning the grill or fryer, and splashing hot grease during cooking. Those treated as outpatients were off from work for as long as 10 days. These data identify an adolescent population at risk for work-related burn injury in fast-food restaurants.

Isolation, molecular characterization and antimicrobial resistance patterns of Salmonella and Escherichia coli isolates from meat-based fast food in Lebanon.

The aim of this study was to characterize at the molecular level the different stains of Salmonella spp. and Escherichia coli that were isolated from meat-based fast food in Lebanon. In addition, this study evaluated the resistance of those strains to different antimicrobials that are commonly used. The foods included were Lahm-bi-Ajeen (LBA, meat pies) and Shawarma (Lebanese meat sandwiches similar to Gyros and Donairs, containing meat, vegetables, and sesame seeds-oil-based sauce). Polymerase chain reaction (PCR) was used to characterize and identify the strains of both bacteria. Salmonella species characterization was performed using rfb genes cluster genetic marker, while that of E. coli strains were carried out based on stx1, stx2, eaeA, fliC, and ehlyA virulence markers. The characterized strains were then tested for their response to various antimicrobials. The results showed that the tested foods were contaminated with Salmonella paratyphi (serogroup A) and Shiga Toxin (Stx)-producing E. coli (STX-EC). The PCR showed that 75% of E. coli tested strains was positive in PCR performed with stx1 primers, one of which was eaeA positive. Two of the tested strains were positive using PCR with fliC primers. The resistances of the various strains were evaluated using the following antimicrobials: Oxacillin, Teicoplanin, Trimethoprim/sulfamethoxazole, Gentamicin, Clindamycin, Cefotaxime, Cefuroxime, Erythromycin, and Vancomycin. Bacteria were highly resistant to one or more of the tested antimicrobials. Approximately 69% of E. coli and 77.8% of Salmonella spp. exhibited resistance. Salmonella spp. were shown to be 100% resistant to four antimicrobials: Oxacillin, Teicoplanin, Clindamycin, Vancomycin, and Erythromycin, while E. coli was 100% resistant to Teicoplanin and Trimethoprim/sulfamethoxazole. The most interesting findings were the high susceptibility of the E. coli to Gentamicin (100%). Highest resistance in the case of Salmonella spp. was seen against Cefotaxime (74%). Those two antimicrobials are commonly used for the treatment of enteric infections caused by gram-negative bacteria. The results showed that meat-based fast foods in Lebanon could be a public health hazard, especially Shawarma, as they may act as a potential vehicle for many antimicrobial-resistant pathogenic organisms. Improper hygienic standards and indiscriminate use of antimicrobials are two of the main causes for the prevalence of these pathogenic resistance strains in Lebanon. These results will emphasize the need to implement protective measures and more emphasis will be placed on the application of hygienic practices to reduce the levels of food contamination.
