Attitudes To Food And Eating Behaviour Essay

Food has long assumed a role in our society beyond filling empty stomachs – it permeates many facets of our life. A healthy nutrition intake is a welcome excuse for our passion about such sensory enjoyments. Would you choose the traditional English roast dinner, a lighter vegetarian selection or oysters on ice? De gustibus non est disputandum – there is no disputing about taste… or is there?

A review of the literature demonstrates that sensations for taste differ in individuals and hence influence their selection. These differences are in part rooted in our evolutionary and genetic heritage that can be ascribed to our physiological necessity to consume food. Moreover though, our food choice is shaped by our socio-cultural context as well as through our own cognitive appraisals. Conversely, in consuming food that suits our gusto we reach beyond its primary nutritional function and portray much about our own culture and style within the societal context.

A sign of refined taste or universal preference?
Culinary treats provoke stimulation to a variety of senses in our sensory systems. It is an interplay of our visual, gustatory and olfactory senses that aids us in our food choices. From an evolutionary perspective these sophisticated information systems were shaped over time to react to changes in the environment and to assist us in separating nutrition high in quality from spoiled food or toxic substances (Schiffman, 1996). For instance, our visual senses are involved in measuring the appearance of food, especially through its colour (Pigott, 1988). Empirical studies show that the colour of food has great influence on our decision whether we ingest or reject it. Fresh meat that owes its bright red colour to the pigment oxymyoglobin will adopt an unattractive greyish-brown colour upon exposure to oxygen and a mere 20 per cent level of the brown pigment metmyoglobin is sufficient for a consumer to reject it (MacDougall, 1982; Hood & Riordan, 1973, cited in Pigott, 1988). In practice, the effects to excite our appetite are frequently exploited by craftsmen of haute cuisine in their skilful colour combination of culinary delights.

The true flavour experience, however, comprises a much larger variety of factors, such as a substance’s ‘concentration, aroma, texture, temperature, colour, and even the sound it makes when it is chewed on or bitten’ (Schiffman, 1996). Our olfactory and gustatory senses work closely together and serve as a further aid to the visual senses in experiencing flavour.

The four classical primary taste senses in humans were found to be sour, bitter, salty and sweet, although we are not limited to those. Could there be a physiological, nutritional basis underlying these primaries that direct our food choice behaviour and our food preferences? Sour tastes are often associated with ‘foul water, corrosion, or bacterial decomposition’ and bitterness can indicate toxic substances, which might help us to avoid their consumption (Schiffman, 1996). Salty dishes are rich in minerals and have an important function in regulating our body fluid, whereas sweet tastes indicate ripeness and stand for food high in carbohydrates. Evidence to support the notion for our preference for sweet tastes comes from observing infants’ facial expressions that signal contentment and satisfaction after sucking on a sweetened dummy (Maone et al., 1990, cited in Logue, 2004).

Although these primary tastes seem equally innate to all humans, genetic differences have been found in our sensitivity to bitter tastes, i.e. in the taste of phenylthiocarbamide, also known as PTC (Logue, 2004). People who perceive PTC as very bitter appear to be equally sensitive to ‘saccharine, caffeine, beer, grapefruit juice, and dark green vegetables including Brussels sprouts’ (Bartoshuk, 1979, cited in Logue, 2004). Since this is genetically inherent, at least it looks as if those who do sense such strong bitter tastes in certain food now have an objective and indisputable explanation for its rejection.

Generally however, our eating habits and preferences are modifiable and often seem to be the result of learned experiences. In this view, our cultural background is a strong determinant for our adopted diet, for it is our cultural environment that teaches us about the types of food that can be eaten, and how they are supposed to taste. While some people might turn up their noses at succulent caterpillars or other insects, such components make up an integral food source in several Asian, African and Latin American countries. And, apart from learning what substances are deemed ‘appropriate’ to serve as food, we also develop our own habitual taste towards certain characteristic flavours that pervade a given cuisine. Chinese dishes are principally associated with flavourings such as ‘soy sauce, ginger root and rice wine’, whereas ‘chilli pepper, tomato and lime’ are attributed to the Mexican cuisine (Rozin, 2006). Such distinct ‘flavour principles’ within a given culture represent familiarity and safety and are therefore more readily accepted. Hence, it might be of little surprise when people become more tolerant in trying unknown food if it is seasoned with familiar flavourings. This even seems to hold true for those individuals who generally have a more adventuresome attitude towards ingesting exotic food (Stallberg-White & Pliner, 1999).

Our attitudes towards food can even serve as a mediator of physiological mechanisms. Findings of a study by Teff and Engelman (1996) yielded a significant correlation between people’s cognitive attitudes towards food and their cephalic phase insulin release (CPIR). The cephalic phase is part of our digestion process that occurs prior to the actual food ingestion.

It is initiated by the sight, smell or even just the thought of food and modulates the levels of insulin release. In the case of Teff and Engelman’s (1996) study, individuals released higher concentrations of insulin after tasting and expectorating food when they had a somewhat restrained attitude towards food compared to eaters that were more open in their approach. It seems then, that palatability is not just an experience of taste but can be mediated by our cognitions (which may therefore play an important role in directing our food choice).

Concerns frequently arise when children appear too reluctant in trying new food and adopt a one-sided unhealthy diet. Such behaviour is known as food neophobia, and generally involves ‘rejection of a novel food  or foods in a particular situation’ (Pliner & Salvy, 2006). Its underlying psychological causes have been explained on the basis of Rozin and Fallon’s (1987) categorisation of food rejection and include dislike, danger and disgust. Dislike of food refers to substances that generally are considered as eatable but the individual does not find them palatable. Anticipated danger can be regarded as a precaution to prevent the consumer from eating harmful substances (e.g. fear of poison mushrooms), and disgust is usually experienced when the new food is considered as inappropriate within a person’s cultural environment and often includes animals or animal products.

Since such adverse beliefs about unknown foods are sensory-affective or cause fear about possible dangerous consequences, they are likely to inhibit us in our selection (Rozin & Fallon, 1987).

Educating the senses
In a recent project carried out in France (see Reverdy et al., 2008) a sensory education programme was implemented in a primary school to find out whether this might help to increase children’s openness towards new food. They received lessons in which they were made familiar with new products by, for example, explaining the origin of certain fruits or dishes. Although an expected long-term effect (beyond 10 months) could not be found, the liking for novel food had increased by the end of the four-month programme.

This is encouraging, in that it shows that education of our senses can lead to higher acceptance of new dishes and thus to a more well-balanced diet. But at the same time the results underpin the influence of the range of other factors in developing a permanent liking for some dishes but not others.

You are what you eat
A German proverb states ‘Man is what he eats’, which implies societal expectations on the quantity of food we consume and the type of food we choose. Researchers even found differing eating norms imposed on men and women as to what type of food is perceived as ‘feminine’ (e.g. a salad) or ‘masculine’ (e.g. a meatball sandwich). Women who eat a ‘small feminine meal’ earn higher social approval than when they eat a larger portion of a ‘masculine’ meal (Basow & Kobrynowicz, 1993, cited in Conner & Armitage, 2002).
Research from psychology and other social sciences has equally emphasised the strong relationship between the foods we choose and the culture and lifestyle we show through its consumption. Judgements and evaluations about our person on the basis of our food choice or brand selection are readily made, even just by inspecting the items stated on our shopping lists (Haire, 1950, cited in Conner & Armitage, 2002). In developed countries, where the range of food on offer is plentiful, our tastes in food have long become a reference for our taste in general and may well play a crucial role in our food selection.

In conclusion, then, some might dispute the idea of taste as invariant and genetic. Others argue from a more profound evolutionary aspect, purely referring to the physiological necessity that directs our behaviour. However, it remains beyond dispute that our environmental context – culture and society – work with our own cognitive attitudes to exert a powerful influence on our food choice behaviour.

Transcript of Factors influencing attitudes to food and eating behaviour

Factors influencing attitudes to food and eating behaviour Social learning theory emphasises the impact that observing other people has on our own attitudes and behaviour towards food. Our eating behaviours are a result of observing models actions. Social Learning Theory Parental modelling According to parental modelling a child’s eating behaviour is learnt by observing the behaviour of their parents. Parents have a control of the foods brought into the house and as such control what is being eaten.
Their research suggests a general association between a parent and a child’s attitudes to food. They reported a consistent correlation between parents and children in terms of their snack food intake, eating motivations and body dissatisfaction. Brown and Ogden They conducted a study into the relationship between a parent and a child’s eating behaviour. They reported a clear relationship between a mother’s food nutrient intake and that of her pre-school children and suggested that parents could be targeted to help combat negative eating habits. Olivera et al Similar Eating behaviours/food nutrient intake Implications of research into Social Learning Theory - Parental modeling This research suggests that parents eating habits are highly influential over their child as children view their parents as models and imitate the perceived behaviour. IDA's Evaluation Points General Educates parents on what is a good diet and so they will have a healthier lifestyle which will lead to their children having a more nutritious diet. Attitudes to food are more than just social learning, food preferences are important, this shows that the theory is reductionist by ignoring other views Impact of parents on children deteriorates as children grow up Methodological Contradictory Evidence Garg et al
observed food choices of 38 participants
watching a happy or sad film
offered popcorn or seedless grapes
sad film p's ate 36% more popcorn
happy film p's ate far more grapes
happy people extend mood with healthy food
sad people increase mood with calorific foods Brown and Ogdens research is based on a correlation and therefore we cannot determine a cause and effect of the results this then means that we cannot determine which variable causes the change in the other variable. Reductionist – this theory suggests that the only answer to our eating behaviours is our social ability. Therefore it overlooks other approaches such as the cognitive and biological. Our thought processes might have an effect on the way we eat and therefore this approach is reductionist. Against biological approach – this theory suggests that the way we eat is determines by our environment and upbringing and therefore overlooks the biological approach. It could be determined by our genes or hormones. Suggests that your mood determines what you eat - bed mood - high calories Cultural influences such as ethnicity can effect eating behaviours this is because children in the UK may develop positive attitudes to food (pizza, crisps and chips) believing them to be tasty and a treat. However children in India grow up believing that spicier foods taste better, while children in Japan may prefer a fish based diet. There’s also considerable variation in food preferences within a culture with some families having a meat based diet and some eating vegetarian meals. Ethnicity studied over 14,000 women aged 18-23 in Australia and this research found that across all ethnic groups the more time spent living in Australia the more similar the eating behaviour to those born there (this is known as the acculturation effect). Ball & Kennedy Rozin suggests that the best predictor of a human beings food preference, habits and attitudes would be information about the ethnic group of that individual rather than a biological measure. Implications This suggests that an individual’s attitude to food is highly influenced by the culture they are living in, even if it is not their own therefore showing that you can adapt to the environment that you are in. Evaluation General Individual differences - may just not like food

Quantities of food are subject of availability Methodological Ball and Kennedy -

Large sample - results more valid, results can be applied across more people

unrepresentative sample, only conducted on women, therefore the results cannot be applied to men Contradictory evidence Ball and Kennedy suggest that it is the environment that effects our eating behvaiour, however, Lesha suggests that it is your ethnicity that matters and influences our eating behaviours IDA's Gender Bias – the research supporting this approach is based mainly on a sample of women and therefore overlooks the factors that effect men and their eating behaviours. Therefore we cannot rely on the research support for this approach. Reductionist – this approach doesn’t take other approaches into account. It focuses completely on how the individual is brought up in their culture and how this affects their eating behaviour. Against biological approach – this theory suggests that the way we eat is determined by our environment and upbringing and therefore overlooks the biological approach. It could be determined by our genes or hormones. Comfort Eating Comfort eaters have a negative attitude towards food as they rely on unhealthy, junk food as their main comforter when feeling low or depressed. Therefore eating unhealthy, high calorie foods such as chocolate. Garg et al Results: Those watching the sad film ate 36% more popcorn and those watching the upbeat film ate far more grapes. Garg claims snacks that taste good ‘jolt you out of a sad mood with a sudden rush of euphoria’. Happy people want to extend their mood with healthy food. He observed food choices of 38 participants
Watched an upbeat and funny or a sad and depressing movie
Offered popcorn and seedless grapes throughout the film Comfort Prolonging a good mood Implications This supports the idea that comfort eating has a significant negative impact on peoples eating behaviour. Evaluation General Methodological IDA's Contradictory Evidence Garg et al used typical cinema food for the high calorific snack which could effect the results as eating popcorn is associated with watching any film
Individual differences could have an effect as people may have a personal preference to what food they eat and therefore this may effect the results
depending on the time of day, before or after lunch will depend on how much each participant eats Application use as if you level out someones mood through therapy or drug you can reduce amount of comfort eating and change attitudes to food
Mood changes several times a day but this doesnt mean your eating behaviour will change with it- could only be with major mood changes Brown and Ogden
Parental modeling influences eating behaviour Culture bias – in certain cultures there are different types and amounts of food available to the people living there. Therefore these people will take different views on food and the way they eat and so their mood may not affect the way they eat. Reductionist – this approach assumes that our mood can affect the way we eat. However, it could be determined by our upbringing and environment or our social situation. Therefore this approach overlooks other theories and is therefore a reductionist. Against biological approach – this theory suggests that the way we eat is determines by our environment and upbringing and therefore overlooks the biological approach. It could be determined by our genes or hormones.
