A characterization of peanut consumption in four countries: results from focus groups and their implications for peanut allergy prevalence

Rates of peanut allergy in the Western world have increased over the last 30 years, although it is unclear why. While eating behaviours are likely to be connected to allergy prevalence, the precise relevant factors are uncertain. This study aimed to investigate dietary differences and changes in dietary habits in peanut consumption (in apparent and hidden forms) in four different countries (Bulgaria, Poland, Spain, UK), specifically chosen because of their different ‘peanut experiences’. Focus groups revealed a common perception that dietary habits have become less healthy, with more consumption of processed foods and an increase in snacking. In addition, ethnic cuisine was perceived to have had an important impact on European eating habits, while participants identified an increase in consumption of more ‘exotic’ forms of peanuts and their products. These findings point to an increase in exposure to peanuts, particularly in hidden forms, that superficially parallels increased prevalence rates. However, it was also clear that participants lacked knowledge about the composition of food and non‐food products. The dietary trends identified here thus warrant further quantitative investigation, particularly in the context of differential national patterns of allergy prevalence – data on which is currently being gathered within the EC‐funded EuroPrevall project.     

Reduced‐fat foods: the shopper’s viewpoint

The inclusion of reduced‐fat foods in the daily diet affords consumers the potential to reduce overall dietary fat. Nevertheless, despite an increased range of these food products throughout the market, there has remained a lack of widespread consumer acceptance. The aim of the study was therefore to understand why consumers choose or reject reduced‐fat foods. Ninety consumers were interviewed by means of a qualitative approach within food retail outlets in the United Kingdom. Thematic content analysis indicated that uptake or rejection of these products is influenced by health concerns, ‘goodness of fit’ with individual dietary health strategies, the preferences of different household members, perceived sensory properties and scepticism towards these products. The results imply a need to explore and innovate ‘natural’ fat substitutes and to improve the sensory quality of reduced‐fat products. Further research is required to determine how these foods are used within the household and incorporated within the overall diet. Policy must seek to restore consumer trust in reduced‐fat food products and the food supply generally.     

Sustainability and dietary change: the implications of Swedish food consumption patterns 1960–2006

This article focuses on the changing food consumption pattern in Sweden between 1960 and 2006, and the implications of those changes for sustainability. National statistical data on the consumption of different food groups such as meat, milk, dairy products, eggs, fruit, vegetables, cereal, potatoes and sugar were compared. Overall, an increase in the consumption of meat, cheese, cream, fruit and vegetables was observed, while the consumption of milk, butter and potatoes decreased. For the sustainability assessment, three parameters were chosen: land requirement, greenhouse gas (GHG) emissions and energy use. It was shown that the Swedish diet in 2006 required more resources and produced more GHG emissions than in 1960, mainly due to the increase in the consumption of animal products.     

Consumer preference among fluid milks: low‐fat vs. high‐fat milk consumption in the United States

The present study uses data from the Continuing Survey of Food Intakes by Individuals 1994–1996, 1998 in order to analyse milk consumption by type, specifically high‐fat milk vs. low‐fat milk. Whereas trend analysis displays an overall increase in low‐fat milk consumption over the last few decades in the United States, a number of individuals still consume high‐fat milk varieties, and overall dietary intakes have yet to achieve recommended levels. In light of recent research regarding fat intakes, it is important to understand what factors might cause consumers to purchase high‐fat options given the number of low‐fat options available in the market. Through the use of Logistic regression, key socio‐economic and demographic variables are analysed in order to determine their impacts on the probability of consuming low‐fat milk vs. high‐fat milk. The results indicate that a number of factors do influence probability of low‐fat milk consumption as compared with high‐fat milk consumption. Most notably, probability of low‐fat milk consumption appears to be positively related to age, education level, and income level. African Americans and other minorities had a lower probability of consuming low‐fat milk when compared with White people in the sample population. Also, those respondents designated as low income or living in the South were less likely to consume low‐fat milk.     

The role of dietary information in women's whole milk and low‐fat milk intakes

This study examines the effects of dietary information on women's whole and low‐fat milk intakes. The sample is 1928 female meal planners aged 20 years or over who provided information on their milk intake for 2 days in the 1994–96 Continuing Survey of Food Intakes by Individuals and who completed the 1994–96 Diet and Health Knowledge Survey in the follow‐up interview. The nested Tobit model was used to handle the sequentially censored data. Women's dietary information contributed to reduced whole milk consumption and increased low‐fat milk consumption indicating different effects on whole milk and low‐fat milk consumption.     

Food consumption,lifestyle patterns,and body mass index of a group of white South African students

There is worldwide concern that higher education students are increasingly engaging in unhealthy eating and lifestyle practices. A total of 488 white students participated in a study aimed at investigating the current food consumption and related lifestyle patterns of students at a South African residential university. The respondents’ self‐reported weight and height was used to calculate their body mass index (BMI). Closed and open‐ended questions measured aspects of the respondents’ usual eating patterns and lifestyles. The meal patterns and composition confirmed Western‐orientated food practices, as the majority consumed three meals a day, with in‐between meal snacking, and a different meal pattern over weekends. Respondents’ food intake was further characterized by a low intake of fruit, vegetables, and dairy products and frequent consumption of foods high in fat, sugar, and sodium. Although the majority (66.8%) of the study group were classified as normal weight according to their BMI, when comparing males and females, more males than females were overweight and obese. Only 54% of the males had a normal weight compared to 82% of the females. There was, however, no statistically significant difference (p = 0.149) between how males and females in the different BMI groups felt about their weight. The study also explored the relationships between the respondents’ BMI, gender, food consumption patterns, and type of residence. The features of the food consumption patterns were depicted according to whether breakfast was eaten or not; snacking activity between meals; the consumption of ready‐prepared convenience meals, fast foods; home‐cooked meals; and eating out. There were no statistical significant differences between the BMI categories of males and females regarding their habit to eat breakfast or not; and to snack between meals either during the morning, in the afternoon or after supper. Similarly, no statistical significant differences were noted when relating the BMI categories of the gender groups to the frequency of consumption of ready‐prepared, convenience type meals, fast foods, and home‐cooked meals. However, a statistical significant difference (p‐value 0.006) was found between BMI categories per gender and general frequency of eating out. No statistical differences was noted between BMI categories, gender and place of residence irrespective of the type, whether the student lived with parents, independently in a flat or apartment, or a house with friends or a room, or in a university residence.     

Nutrition knowledge and lunchtime eating habits of secondary school children in Lothian

A total of 103 secondary school children attending five schools managed by Lothian Regional Council were surveyed to establish nutrition knowledge, attitudes and beliefs about healthy eating and their patterns of food consumption at lunchtime on schooldays. The results indicate that nutrition knowledge was surprisingly good and the children surveyed were proficient at identifying foods that were high in fibre and low in sugar, salt and fat. When questioned about their liking for foods, however, many identified foods that were characteristically high in fat, sugar and salt, and low in fibre. Examination of the dietary diaries kept at lunchtime confirmed that consumption of these types of foods was typically high, with very low consumption of fruit and vegetables being reported and high intakes of carbonated drinks, confectionery and chocolate. This conflict between nutrition knowledge and food choice patterns is discussed in the light of the probable future effects on health and the implications for health educators.     

Food consumption patterns,dietary quality and health status of expectant mothers: case studies in suburban and rural communities in Ghana

The study was conducted to determine the food consumption patterns, dietary quality and health status of expectant women and also to assess their level of awareness of nutritional requirements during pregnancy. Food beliefs, taboos and superstitions held by the women were also investigated. Using the purposive sampling technique, 30 pregnant women attending the Maternal and Child Health Clinic at Dodowa (rural) and University Hospital, Legon (suburban), were selected for the study. A structured questionnaire was used to collect information on the respondents’ nutritional knowledge, beliefs, taboos and superstitions and health status. A food frequency questionnaire and the 24‐h dietary recall method were used to obtain information on food consumption patterns and dietary quality. The study revealed that, although the majority of the respondents (83.3%) had some knowledge of nutrition, not all were applying it in their feeding practices because of financial constraints. With regard to consumption patterns, most of the women (83.3%) were having three meals a day, while the rest either ate twice a day or anytime they were hungry. Seventy‐three per cent of the respondents also increased their food intake during pregnancy. Foods eaten were based mainly on starchy roots and tubers, cereals and vegetables. Legumes, oilseeds and fruits were often lacking in the main meals of respondents. Although animal products were consumed daily, the quantities taken were very small to provide for adequate protein, especially in the rural area. Various types of food were avoided by some of the expectant mothers for reasons such as nausea, loss of appetite, taboos and superstition. With regard to dietary quality, respondents from the rural area had diets of poorer quality in terms of nutrient intake compared with those from the suburban area. In both communities, iron contents of diets were quite low. Forty‐seven per cent of the women interviewed were anaemic, with a higher prevalence of anaemia being observed in the rural community. Common ailments reported by the women were dizziness, headache, waist pains and malaria. Based on the results of the study, it was recommended that nutrition education for pregnant women should be stepped up at antenatal clinics especially in rural areas.     

Indian food in the UK: personal values and changing patterns of consumption

This qualitative study examined the consumption of Indian foods among groups of English and Indian people living in the UK. Both convenience and freshly made Indian foods were included in the research. The aim was to explore attitudes (based on ethnicity) towards, and the consumption of, Indian foods. The means–end model and laddering methodology were used in interviews with 24 respondents, 12 from each group (English and Indians). The personal values ‘social life’, ‘health’, ‘adventure’, ‘enjoyment’ and ‘savings’ were found to be the most important for English respondents whereas ‘enjoyment’, ‘good life’, ‘health’, ‘religion’ and ‘culture’ were the most desirable value ends for Indians. The results provide an insight into English and Indian peoples’ perceptions of Indian food that can be used in promotion and marketing positioning of branded Indian foods, sauces and accompaniments.     

Changing risk perceptions and food-handling practices of Oregon household food preparers

Results of 1986 and 1995/6 statewide random surveys were compared to assess changes in the risk perceptions and food-handling practices of Oregon food preparers. The 1986 survey revealed that perishable foods (baked potatoes, hard-boiled eggs, sliced turkey and cream pie) were often held at room temperature for longer than 2–3 h. Those who perceived greater food safety risks were significantly less likely to report temperature abuse of cream pie (P < 0·02) and baked potatoes (P < 0·001). Respondents reported serving raw and/or rare animal products (fish, milk, hamburger and pork) in both surveys. More food preparers perceived that serving undercooked foods was a ‘high’ risk in 1995/6 than in 1986. More (88%) also perceived that serving raw hamburger was a ‘high’ risk in 1995/6 than in 1986 (52%), possibly because of media coverage linking under-cooked hamburgers to the E. coli 0157:H7 outbreak in the Pacific Northwest. Those who perceived a ‘high’ risk were less likely to serve raw fish (P < 0·038) and raw milk (P < 0·002). Significantly more females perceived raw milk to be a ‘high’ risk (P < 0·003). The risks of consuming both raw fish and raw milk were more likely to be underestimated, however. Food safety education is therefore needed to help food preparers to identify ‘high’ risk foods and to motivate them to minimize risks.     

Perceptions of food quality: Evidence from a survey in Shanghai

Recent food scandals in China significantly decreased the level of consumer trust toward the food chain, and, at the same time, increased the demand for food quality and safety. This paper investigated perceptions and determinants of food quality among a sample of households in Shanghai. Survey questionnaires were collected between June and December 2014, and a total of 509 interviews were completed. Questions asked about food purchasing behaviours, dietary habits, and the importance of food quality when food shopping. Socio‐demographic and socio‐economic variables were also collected. We used ordered logit regressions to investigate the most significant factors associated with food quality. We found that respondents who frequently bought vegetables were 31% more likely to look for quality attributes (p < .1) and respondents who often bought rice 28% more (p < .01). Branding was also positively associated with the demand for food quality. In particular, consumers considering brand an important element were 25% more likely to believe that the product was of high quality (p < .05). Among socio‐economic variables, higher income and education were significantly associated with food quality demand. Our results indicated that consumers in Shanghai paid increasing attention to food quality, and they especially associated it with traditional foods and brand. We suggested that policy makers and stakeholders in the food chain should strengthen food quality certification systems, and help consumers make better and more informed choices.     

Consumers' awareness,acceptance and attitudes towards functional foods in Turkey

The aim of the present study was to investigate consumers' awareness, acceptance and attitudes towards functional foods in Turkey. Eight hundred and eight people participated in this study: aged between 20 and 80 years, 38.5% were male and 61.5% were female. Participants were given a questionnaire and were asked to fill it in by themselves to minimize the influence of the interviewer. Results indicated that socio‐demographic characteristics such as age, education level and income level are important indicators of consumers' awareness and consumption of functional food. The results show that the female respondents were 2.987 times more aware of functional food than the male respondents. Similarly, the likelihood of respondents having awareness of functional food was 1.431 times greater among those who had a higher educational level than among those with a lower educational level. Consumers who used vitamin supplements were 1.228 times more aware of functional food than other consumers. The results show that older respondents were 3.395 times more aware of functional food than younger respondents. Respondents with a history of familial diseases were more likely than others to have consumed margarine with plant sterol, fruit juices fortified with vitamin C, and breakfast cereals fortified with vitamins and minerals. Those with a diet‐related problem were more likely to have consumed cholesterol‐lowering products than those without a problem. As a conclusion, this study has shown that socio‐demographic characteristics such as age, education and income levels, and prices are important indicators that influence consumers' awareness and consumption of functional food. These results suggest that this type of knowledge could affect consumers' interest in functional foods, and therefore educational strategies might be necessary to encourage the consumption of functional foods.     

Food safety knowledge and practices of consumers in the U.S.A.

Use of safe food handling practices in the home could reduce the number of foodborne illnesses. The objective of this project was to obtain baseline data on the safe food handling knowledge and practices of consumers to aid in the development of effective educational programmes. A food handling questionnaire was developed and completed by 426 Nebraskan respondents. Knowledge and practice questions were based on the most important contributory factors in reported foodborne illness outbreaks. Knowledge scores (correct responses) ranged from 2 to 29 with a mean of 20 ± 4. When compared with the knowledge score, the respondents' education level, where they lived and their sex were statistically significant. Almost all (96%) of the respondents stated that they practised safe food handling when persons were infected. Approximately half of the respondents indicated that they practised safe food handling when handling contaminated raw foods and using foods from unsafe sources. About 45% of the respondents inappropriately left foods at room temperature. One-third of the survey respondents improperly held hot foods. Cross-contamination was a concept understood by 75% of the respondents. Results indicate that food safety education should be targeted on specific groups who are less knowledgeable about safe food handling practices. Results also indicate that a number of respondents knew proper food handling concepts but did not put those concepts into practice. Therefore, increasing the adoption of safe food handling practices by consumers should become an important aspect for educators in food safety educational programmes.     

Parental work status and children's dietary consumption: Australian evidence

This study investigated associations between parents' work status and the dietary consumption patterns of Australian children, and whether such associations vary by parental education and usage of nonparental childcare. Data from the longitudinal study of Australian children at two waves from ages 2–3 years (n = 4601) to 4–5 years (n = 4381) were analysed. Logistic regression models were used to calculate odds ratios of children consuming (≥1 times/day) fruit and vegetables (FV), high fat foods (HFF), high sugar drinks (HSD), as well as evaluating the incidence of breakfast consumption. This was analysed against the employment status of parents including full‐time, part‐time and unemployed. Children of part‐time employed mothers were more likely to consume breakfast, and less likely to consume HSD compared with children of full‐time employed mothers. Children of part‐time employed fathers were less likely to consume FV and breakfast, and more likely to consume HSD compared with children of full‐time employed fathers. Children of nonemployed mothers were more likely to consume HFF, whilst those of nonemployed fathers were more likely to consume HSD and less likely to consume breakfast compared with other children. Amongst less‐educated parents, children of unemployed and part‐time employed parents were more likely to consume HFF and HSD and less likely to consume FV and breakfast compared with children of full‐time employed parents. Amongst highly educated parents, children of unemployed and part‐time employed mothers were less likely to consume HSD compared with children of full‐time employed mothers. Children of part‐time employed mothers who used family day care, day care centres and grandparent care were less likely to consume HSD and more likely to consume breakfast compared with children of full‐time employed mothers. Children of part‐time employed fathers and unemployed parents who used day care centres and grandparent care were less likely to consume FV and more likely to consume HFF compared with children of full‐time employed parents. Future studies should pursue a better understanding of the mechanisms for the adverse effects of parental work status on dietary consumption to develop and enhance specific interventions targeting these groups.     

Sodium content in foods: Brazilian consumers’ opinions,subjective knowledge and purchase intent

This study attempted to gain insights on Brazilian consumers’ subjective knowledge of sodium content in processed and homemade foods and their purchase intent for products with reduced‐sodium content. A questionnaire was distributed to 409 consumers selected by convenience quota sampling. We found that Brazilian consumers were concerned about the amount of salt (sodium chloride) in the products they consumed, regardless of educational levels, income, age, lifestyles, or health conditions. However, they still considered their consumption to be above WHO‐recommended limits and had little subjective knowledge about the term ‘sodium’. While processed products were considered the main contributors of high‐sodium intake, participants were not concerned about addition of salt at the table and salt in homemade food. The majority of respondents rarely read the sodium content on food labels; however, men and older individuals were more likely to read label information on sodium content. Products with reduced sodium were found to have market appeal, which justifies investments in research to develop these products. Therefore, in addition to the efforts to reduce sodium in the processed‐food industry, it is necessary to promote awareness about the importance of food labelling, especially sodium content, and the need to reduce salt in homemade food and additions during meals.     

Independent decision making of adolescents regarding food choice

The adolescence period is the stage in the life cycle in which individuals begin to develop independent decision making related to their social environment including their dietary intake. The period is fundamental in the development of longer term eating habits that may be reflected in adulthood. This study aimed to investigate the decision‐making process of adolescents and their dietary behaviour in the achievement of a balanced diet and to determine the underlying factors that may affect these choices. To meet this aim, a three phase data collection was utilized. In phase 1, a baseline questionnaire (n = 239) measured factors affecting dietary behaviour and the barriers in the achievement of a balanced diet. Phase two employed and measured respondents’ (n = 235) independent decision making by rating nineteen menu choices which reflected all options of dietary guidelines. This was analyzed through conjoint analysis. In phase three a subsample (n = 55) from the first two phases completed a food map which determined underlying reasons for food decisions and choice behaviour. Results revealed that when adolescents are given free choice they tend to follow an unbalanced diet with some diets raising concerns for their current and future health. Fifty‐seven percent of respondents displayed serious concerns in their dietary choice of which 18% were identified as requiring immediate intervention. The most noticeable factors affecting dietary choice were the desire to eat foods high in fat and carbohydrates and low in fruit and vegetable consumption. Food‐mapping indicated prior knowledge and attitudes had no effect on the choices made but that that behaviour of parents in the preparation of meals at home and peers in the selection of snack choices had the most influence on the unbalanced diet.     

Think before you eat: photographic food diaries as intervention tools to change dietary decision making and attitudes

This paper examines the use of photographic and written food diaries as interventions to raise awareness of and change dietary habits. Weinstein's precaution adoption theory and Guagnano, Stern and Dietz's Attitude Behaviour Context theory provide the theoretical basis to explain why nutrition knowledge does not result in healthy eating behaviour and why an intervention may be necessary to change attitudes and behaviours. A pilot study using written and photographic food diaries was conducted with 43 participants. Qualitative analysis of participant interviews revealed that photographic food diaries can alter attitudes and behaviours associated with food choices, and they are more likely to do so than written diaries because they serve as an intervention at the point when decisions regarding what to eat are being made.     

Parents’ knowledge,behaviour and concerns of food chemical hazards: Korean mothers sending their preschool‐aged children to child care centres

Although incidences of foodborne illness caused by chemical hazards are increasing, the studies on public awareness of food chemical hazards are limited. This study was conducted to assess mothers’ knowledge, behaviour and concerns on diverse food chemical hazards. A total of 960 mothers sending their preschool‐aged children to child care centres in Gwanak‐Gu, Seoul, Korea were surveyed, and 633 (65.9%) returned the questionnaires. After excluding inappropriate questionnaires, 364 (37.9%) were analysed. The majority of the mothers were able to identify food categories containing acrylamide (83.2%) and trans fat (80.2%), while slightly over half of the mothers named food categories containing allergen (56.3%) or pesticide residues (57.1%). Less than two thirds of mothers were knowledgeable of human exposure pathway to environmental contaminants (59.3%), acrylamide (55.2%) or heavy metals (65.9%). A significant number of mothers showed familiarity on health risk from dietary exposure to environmental contaminants (82.4%), trans fat (91.5%) or heavy metals (96.7%) (P < 0.05). The data on safe food behaviour towards environmental contaminants (81.8%), acrylamide (98.0%), heavy metals (96.7%) and trans fat (90.6%) showed high levels of right behaviours. About 47.2% and 22.8% of mothers read label of food additives and ingredient statement on allergen when purchasing processed foods, respectively. Mothers seemed to be concerned about food chemical hazards. Among the sociodemographic characteristics, only age significantly differentiated mothers’ concerns on chemical hazards in foods (P < 0.05). This study suggests that mothers needed to be educated on food chemical hazards regardless of their education levels, occupation status or the number of child.     

Genetically modified foods: Consumer awareness,opinions and attitudes in selected EU countries

The dynamic development of biotechnology in recent years has raised serious public concerns about the possible risks arising from genetically modified organisms (GMOs). The aim of this study was to investigate consumer opinions regarding genetically modified (GM) foods. The research also aimed at verifying the differences in the attitudes of respondents from two, relatively culturally diverse research sites. To obtain empirical data a face‐to‐face survey was conducted in 2015. It covered a total of 976 randomly selected individuals. The study was performed in the capital of the United Kingdom—London and the Polish capital—Warsaw. The results of the study show that almost half of the respondents were familiar with the GMO concept. According to the respondents, the greatest benefits arising from the genetic modification are: enhanced shelf‐life of food and crops' resistance to extreme climatic conditions. The main disadvantages were: unpredictable consequences of deoxyribonucleic acid (DNA) modification, production of species‐specific toxins and food allergenicity. Over two thirds of people surveyed support the idea of the obligatory labeling of GM foods. The information presented on food packaging should primarily include potential contraindications to the consumption, indication that food was produced using transgenic sources and a warning about potential allergenicity. An almost equal number of respondents showed intention for purchasing GM food products, an intention to act otherwise, or was not decided. As many as 27.7% of survey participants showed negative attitudes toward GM foods, whereas only 19.8% predominantly positive. It is worth noticing that, with only one exception, no statistically significant differences were observed between the opinions of Polish and British respondents.     

Consumer Perceptions of “Functional Food” in the United States

There is a strong trend to market products that promise improved health in the United States. Functional food is a rather new concept promoting the healthfulness of foods. Functional food manufacturers should provide motivating and trustful marketing messages. However, since the term “functional foods” lacks definition, communication to consumers is challenging and can be confusing. This study investigates how U.S. consumers understand the concept of functional foods. An online survey containing 64 questions was structured to measure awareness, consumption, and trust toward functional foods. Based on a definition provided in the survey, a clear minority (15%) of the respondents (n = 1027) stated they had heard of functional foods before the survey. Compared to the respondents who had not heard of functional foods, they more often used whole wheat cereals, vegetable juice, carrots, toast with high fibre and green tea (Chi-square –test, p < 0.001). Food and drug administration (FDA), health associations, and dieticians were the most trusted sources of information for functional food decisions with 28%, 24%, and 20% shares of the respondents, respectively. Food producers, food retailers and media together were chosen as the most trustworthy source by less than 1.5%. We concluded U.S. consumers find functional foods confusing and even unreliable. To strengthen their confidence, we suggest clear and transparent collaboration with nutrition and health specialist and product- specific marketing messages based on solid scientific documentation.
