Learning Objectives
By the end of this chapter you should have developed a knowledge and understanding of the health, dietary, socio-economic, cultural and religious factors that affect people’s choice of food, including:
* availability, cost, personal preferences, storage, cooking facilities, and the effects of advertising, promotions and food scares
* how cultural preferences, religion, lifestyle, health and multicultural factors have influenced food production
* the implications that sustainability, food miles, seasonality, local food, genetically modified foods, organic and free-range foods, Fairtrade and Farm Assured have for the environment.
Factors affecting your choice of foods
A range of factors affect your choice of foods. These include the foods available, costs, personal preferences, storage and cooking facilities, the effect of advertising, promotions and food scares.
Availability
Choice depends on the type of food available in the country and place where you live. In developing countries, such as in parts of Africa, there is very little choice and often insufficient food available, and they may not be able to grow produce because of climate, or because they cannot afford expensive agricultural equipment.
In the UK there is a wide variety of food because of technological developments and improvements in the growth, transport, preservation and storage of food. Food technologists have also created many new foods, such as Quorn®. We can import foods that we cannot grow ourselves. In the UK we can go to the supermarket at any time of the year and buy whatever food we want, as long as we are prepared to pay for it.
Cost
One of the most important infl uences on food choice is what people can afford to spend. People have to think of ways they can save money on their food bill, for example:
* using cheaper protein foods, for example, eggs, cheese and pulses
* buying locally grown vegetables or even growing your own
* buying special offers, such as ‘buy one get one free’
* using a variety of supermarkets and planning meals around their special offers
* buying foods with a short shelf life that have been reduced in price
* not wasting foods – the average family in the UK throws away £600 worth of food in a year
* following the advice of the eat-well plate and using more carbohydrates (which are cheaper) in meals
* adapting recipes by swapping expensive ingredients for cheaper ones, for example, yoghurt instead of cream
* planning meals and shopping carefully
* using ‘own-brand’ economy-range products
* buying loose produce, which is often cheaper than the pre-packaged varieties
* using economical methods of cooking.
Better-off people tend to buy more protein foods, so their starch and fi bre intake tends to decrease, while those on lower incomes tend to buy less fruit and vegetables, thus having a lower intake of vitamins and minerals.
Personal preferences
We all have our personal likes and dislikes and are influenced by our senses. We use all of our five senses when we eat. These give us information about the food.
The five senses are:
* Sight– the appearance (aesthetics) of food can make it look more or less appetising. Aspects such as colour, size, shape, age, texture, garnish and decoration will all affect how you feel about the product.
* Sound– some food products make sounds during preparation, cooking, serving or eating. For instance, the crackle of popcorn, the sizzle of bacon, the crunch of crisps and raw carrot.
* Smell– you can detect the aroma of foods, such as ripeness and freshness of apples and cabbage. Aroma stimulates the digestive juices and makes the food seem more appetising.
* Taste– taste buds detect four groups of flavours: bitter, sweet, sour and salt. Flavour develops when the food is combined through chewing and mixing with saliva.
* Touch– the surface of the tongue is sensitive to different sensations, such as moist, dry, soft, sticky, gritty, crumbly, mushy. As we bite and chew food we can feel how hard or soft it is through our teeth and jaw. These qualities are known as ‘mouthfeel’; if they are missing, food is considered to be unpalatable.
Key points
* The characteristics of food that affect our organs are known as organoleptic qualities.
* Smell and taste work together to develop the flavour of food.
* The sensitivity of the tongue is reduced when the food is either very hot or very cold.
Storage and cooking facilities
Food technologists are continually developing new food products that require little preparation and are easy to store and cook.
Most households have a microwave to reheat convenience foods. A refrigerator is considered an essential item of equipment to ensure food safety – if you do not have a refrigerator, your choice is restricted to canned and dried foods.
Many households have a freezer, which means that that they can shop weekly.
If you do not have the skills to prepare ingredients, you can buy them ready-prepared, such as frozen vegetables. Students at university and the elderly, for instance, often have limited cooking facilities. However, these can be expanded through the purchase of a wide range of cooking equipment that will perform different tasks, including low-fat grilling machines, electric woks and electric barbecues.
Advertising and promotions
We are strongly infl uenced by our peer group and by the media. Manufacturers spend many millions every year on advertising, especially on chocolate, crisps, snacks and sweets. Also, manufacturers may promote the product by special offers, free gifts and competitions.
Ways of advertising and promoting food products include:
* advertisements on the television and the internet, in cinemas, newspapers and magazines, and on posters and fl yers
* displays in supermarkets and shop windows
* special money offers, such as ‘buy one get one free’ (bogof) or money-off coupons
* celebrity endorsements by sports or pop stars
* competitions
* free samples or tasting in supermarkets
* free gifts
* eye-catching, attractive packaging.
We watch chefs on the television and see advertising all around us. This influences our choice of food.
Advertising must be legal, decent, honest and truthful, and this is monitored by the Office of Fair Trading.
Food scares
Food scares in the media have a dramatic infl uence on food choice and sometimes result in product sales dropping so dramatically that the company involved ceases to exist. Recent food scares include:
* salmonella in eggs
* hazelnut yoghurts
* listeria in chilled foods
* dioxins in Coke (in 1999)
* E. coli in meat products
* food contamination during production, for example, metals, insects, glass, fabric
* BSE.
Cultural, moral and social influences
Culture
The word culture is used to describe our way of life. A cultural group is a group of people who share the same norms, beliefs and values.
We adopt the eating patterns of our parents from infancy; we learn to like the foods that our families like. Styles of eating and cooking tend to be determined by the availability of cheap, locally grown food products. Rice is the staple crop in India, China and Japan, the potato in Britain and yams in parts of Africa.
Wheat is grown in many countries, but is used in a variety of ways.
In some cultures and religions certain foods are not permitted because they are considered ‘dirty’ or ‘unclean’ or sacred. Manufacturers are influenced by cultures – if there is a demand for a certain type of food they will respond. Certain foods have become an important part of celebrations in many cultures, such as:
* special events in the year, for example, Christmas, Divali
* birthdays
* weddings
* retirements
* special achievements
* celebrating someone’s life.
There are many more.
Religious and moral issues
Religious beliefs influence eating habits, as religions often have laws related to foods.
Hinduism
The cow is sacred to Hindus, so they will not eat beef or any product from slaughtered cows. They avoid foods that may have caused an animal pain, so are usually vegetarians and have many days of fasting.
Sikhism
Sikhs have similar eating habits to Hindus. Again, many are vegetarian. Some do not drink alcohol, tea or coffee.
Islam
Muslims have a set of dietary rules. The pig is considered unclean, so Muslims do not eat pork or any pork products. Other meats and poultry must be slaughtered in a particular way so that no blood remains. This is called Halal meat. Unlawful foods are called ‘haram’ and include alcohol and caffeine.
Judaism
Food is an important part of the Jewish religion. Kosher food is food that Jews are allowed to eat. Meat must be specially slaughtered, soaked and then treated with kosher salt. Jews do not eat pork. Meat and dairy produce must not be eaten at the same meal.
Rastafarianism
Rastafarians eat food that is natural and clean. They do not eat pork and only eat fish that is longer than 30 cm. They cook with coconut oil and do not drink alcohol, milk or coffee.
Buddhism
Most Buddhists are vegetarian.
Lifestyle
Eating habits have been affected by social changes within households during the past 30 years. Changes in lifestyle due to both parents working and the consequent increase in income (two wages) have resulted in people spending less time in the kitchen preparing food from raw ingredients, choosing to buy more foods that are ready to eat or just need reheating, and an increase in eating out. In some homes, due to different members of the family eating at different times, some of the traditional mealtimes of breakfast, lunch and dinner are being replaced by snack meals and takeaway dinners.
Lifestyle factors that affect eating habits include:
* More mothers are employed outside the home.
* More people live alone.
* People travel greater distances to work.
* People have social activities outside the home.
* The use of convenience foods and ready meals, and the availability of takeaways allow people to have more flexible lifestyles.
* There has been an increase in snack foods available.
* There is a wide variety of foods available to choose from.
* There are many types of restaurants in most cities.
* There is less emphasis on the family meal, and family members eat when they want to (grazing).
Health
The nutritional needs of individuals and groups of people are affected by their health. Eating for health means making small changes to the meals that we already eat.
We should all choose foods carefully:
* Overweight people should choose lowcalorie, low-fat foods.
* People recovering from an injury or illness should choose high-protein foods.
* Someone recovering from a heart attack should choose products lower in fat.
* Anyone suffering from high blood pressure is usually advised to have a diet lower in salt.
Many people are in hospital because of diet-related conditions. We do not have deficiency diseases in the UK, but there is a problem because of people eating the wrong foods.
Sustainability issues
Your choice of food products affects the environment. This includes moral issues, seasonality, local food, organic and free-range foods, genetically modified foods, sustainable design, food miles, Fairtrade foods and Farm Assured foods.
Moral issues
Some people may make moral decisions, for example, vegetarians who decide that it is morally wrong to kill animals to eat their flesh. Other current moral issues affecting food production include: intensive farming, genetically modified foods, animal welfare, factory farming, selective breeding.
Factory-farmed animals are often kept in very distressing conditions – cramped, with limited lighting and no room for the animals to move or exercise.
Free-range animals are allowed to live and grow in natural surroundings. Products from these animals will cost the consumer more because the farmer will not produce as much.
Selective breeding has resulted in egg-laying hens that will produce 300 eggs a year. A broiler chicken, reared for meat rather than eggs, will reach its slaughter weight in about 40 days.
Seasonality
This relates to the availability and use of products when they are in season. We have become accustomed to going into supermarkets and buying anything at any time, but the production of crops in the UK is limited to short seasons during the year. The range of products and ingredients available for us to buy is a result of globalisation. This has been made possible by improved storage, preservation and transportation of foods. Our food products travel many miles to reach our table. Think about the effect on the environment of the miles that food travels. This is called the carbon footprint of the product, or food miles.
Key terms
Organic – grown or reared without the use of artificial aids/fertilisers/pesticides/antibiotics
Genetically modified – describes crops in which the genetic structure of the cells has been changed
Sustainability – this means reducing the impact of a product on the environment
Fairtrade – guarantees that disadvantaged producers get a fair deal
Farm Assured – guarantees the highest standards of food safety and hygiene, animal welfare and environmental protection
Globalisation – process by which different parts of the globe become interconnected by economic, social, cultural and political means
Carbon footprint – the amount of carbon emissions produced in the growing, processing and distribution of our food
Local food
Local products means that you are getting quality products with a low carbon footprint. We can eat with the seasons.
A new trend is for households to have boxes of organic local produce delivered to the door.
Organic foods
Most farming relies heavily on artificial chemical fertilisers and pesticides. Around 350 pesticides are permitted in the UK, and it is estimated that 4.5 billion litres of them are used annually. There can be concerns about their long-term effect on us and they can harm the environment too, for example, chemicals in pesticides leach into rivers and pollute the water.
Organic agriculture is carried out to a set of legally defined standards. Producers then pay to have their produce monitored and certified by one of several organic organisations, of which the Soil Association is the largest in the UK. The Soil Association was founded in 1946 by a group of farmers, scientists and nutritionists who observed a direct connection between the health of the soil, food, people and the environment. Today the Soil Association is the UK’s leading organic organisation, with over 200 staff based in Bristol and Edinburgh. It is an educational charity with some 27,000 members and its certification subsidiary, Soil Association Certification Ltd, certifies over 80 per cent of organic farming and food processing in the UK.
Organic farming strictly limits the use of artificial chemical fertilisers or pesticides. Antibiotics for animals are kept to an absolute minimum. Genetically modified crops are forbidden. Organic bodies also demand more space for animals and higher welfare standards.
In Brazil thousands of children pick oranges to be made into concentrate and processed into juice. They are often exposed to high levels of pesticide and may be paid as little as 13p an hour.
So, what does organic mean?
* All food sold as organic must be approved by organic certification bodies and produced according to stringent EC laws.
* It is produced by farmers who grow, handle and process crops without synthetic fertilisers, pesticides and herbicides or any other artificial ingredient.
* It will not contain any genetically engineered ingredients.
* Organic meat, poultry, eggs and dairy products come from animals that are given no antibiotics or growth hormones.
* Organic producers can only use natural fertilisers, not synthetic ones.
Organic foods are considered to taste nicer, avoid the risk of a combination of chemicals and respect soil structure and wildlife
Genetically modified foods
The use of new technology in the food industry is controversial, especially products made by modifying or engineering the genetic make-up of food. It might improve the quality of the food, for instance, blackcurrants can be modified to make them higher in vitamin C, tomatoes can be modified to improve their flavour or keeping qualities.
Advantages of genetically modified (GM) foods are:
* improvements to quantity and quality of food
* can grow in adverse conditions, for example, drought
* herbicide and insect-resistant, therefore thrive better
* high nutritional quality
* cheaper to produce.
The concerns about GM foods include:
* long-term safety is unknown
* environmental effects, as the pollen from GM crops does not stop in one place
* ethics – we need adequate labelling: if a product has over 1 per cent of GM food this must be stated on the label; if it is under 1 per cent it does not need to be stated.
Sustainable design
The choices we make as consumers and designers have an impact on other people, especially elsewhere in the world. If we buy chocolate, coffee or tea in the supermarket there are consequences for the people in Kenya, Sri Lanka, Nicaragua and many other places. These consequences extend to their families, schools, communities, and so on. We have a moral dilemma whether to buy British or support developing countries in some way. By eating food out of season and from far away we are using up the world’s resources.
Eco footprint
More people are stopping to consider the impact that our food has on the environment. ‘Eco footprint’ is the term used to refer to the measurement of our actions on the environment. As a designer you must consider the effect of your product on the environment from the first stages of your design ideas through to the final making and eventual disposal or recycling of your product.
Food miles
The distance food travels from fi eld to plate is a way of indicating the environmental impact of the food we eat. Half the vegetables and 95 per cent of the fruit eaten in the UK comes from beyond our shores. Food is transported across the world because we want to buy foods out of season. Asparagus is only in season for May and June in the UK, but we want to buy it all year. It comes from Italy or Spain for a few months and the rest of the year it comes from Peru!
Planes are powered by fossil fuel oil. When the oil is burnt it gives off carbon dioxide gas emissions which contribute hugely to global warming. You can offset this by planting trees to absorb the C0² given off. This is called carbon offsetting. If we reduced the amount of packaging used in products, it might reduce costs and save energy in terms of fuel and transportation.
What can we do? Buy local! This means supporting local growers. It is much better for the environment if you grow and/or buy local organic produce.
What is Fairtrade?
Fairtrade is about better prices, decent working conditions, local sustainability and fair terms of trade for farmers and workers in the developing world. By requiring companies to pay sustainable prices (which must never fall lower than the market price), Fairtrade addresses the injustices of conventional trade, which traditionally discriminates against the poorest, weakest producers.
The Fairtrade Foundation has licensed over 3,000 Fairtrade certified products for sale through retail and catering outlets in the UK. The UK market is doubling in value every two years. The UK is one of the world’s leading Fairtrade markets, with more products and more awareness of Fairtrade than anywhere else. Around 20 per cent of roast and ground coffee sold in the UK retail market is Fairtrade. Stable prices mean that coffee farmers can plan for the future.
Fairtrade food products include:
* bananas
* cocoa
* coffee
* dried fruit
* fresh fruit and fresh vegetables
* honey
* nuts/oil seeds
* rice
* spices
* sugar
* tea.
Organisations such as Traidcraft use only ethically produced materials and ingredients, which helps both the producers and the manufacturers in developing countries. Adriano Kalilii, a tea plucker from Kibena in Tanzania, can afford iron sheets to roof his house thanks to Fairtrade.
Farm Assured
We all want quality food that is affordable and safe to eat. The Red Tractor is an independent mark of quality that guarantees that the food we are buying comes from farms and food companies that meet high standards of food safety and hygiene, animal welfare and environmental protection. Look for the Red Tractor Assurance logo.
Key points
* The Fairtrade mark is an independent consumer label that appears on products as a guarantee that disadvantaged producers are getting a better deal. It guarantees that farmers in developing countries get a fair price for their products, which covers their costs.
* Organic foods avoid health risks associated with a combination of chemicals used as pesticides and herbicides.

By the end of this chapter you should have developed a knowledge and understanding of the health, dietary, socio-economic, cultural and religious factors that affect people’s choice of food, including:
* availability, cost, personal preferences, storage, cooking facilities, and the effects of advertising, promotions and food scares

Factors affecting your choice of foods
A range of factors affect your choice of foods. These include the foods available, costs, personal preferences, storage and cooking facilities, the effect of advertising, promotions and food scares.

Sustainability issues
Your choice of food products affects the environment. This includes moral issues, seasonality, local food, organic and free-range foods, genetically modified foods, sustainable design, food miles, Fairtrade foods and Farm Assured foods.

Today the Soil Association is the UK’s leading organic organisation, with over 200 staff based in Bristol and Edinburgh. It is an educational charity with some 27,000 members and its certification subsidiary, Soil Association Certification Ltd, certifies over 80 per cent of organic farming and food processing in the UK.
Organic farming strictly limits the use of artificial chemical fertilisers or pesticides. Antibiotics for animals are kept to an absolute minimum. Genetically modified crops are forbidden. Organic bodies also demand more space for animals and higher welfare standards.

* herbicide and insect-resistant, therefore thrive better
* high nutritional quality
* cheaper to produce.
The concerns about GM foods include:
* long-term safety is unknown
* environmental effects, as the pollen from GM crops does not stop in one place
* ethics – we need adequate labelling: if a product has over 1 per cent of GM food this must be stated on the label; if it is under 1 per cent it does not need to be stated.
Sustainable design
The choices we make as consumers and designers have an impact on other people, especially elsewhere in the world. If we buy chocolate, coffee or tea in the supermarket there are consequences for the people in Kenya, Sri Lanka, Nicaragua and many other places. These consequences extend to their families, schools, communities, and so on. We have a moral dilemma whether to buy British or support developing countries in some way. By eating food out of season and from far away we are using up the world’s resources.
Eco footprint
More people are stopping to consider the impact that our food has on the environment. ‘Eco footprint’ is the term used to refer to the measurement of our actions on the environment. As a designer you must consider the effect of your product on the environment from the first stages of your design ideas through to the final making and eventual disposal or recycling of your product.
Food miles
The distance food travels from fi eld to plate is a way of indicating the environmental impact of the food we eat. Half the vegetables and 95 per cent of the fruit eaten in the UK comes from beyond our shores. Food is transported across the world because we want to buy foods out of season. Asparagus is only in season for May and June in the UK, but we want to buy it all year. It comes from Italy or Spain for a few months and the rest of the year it comes from Peru!
Planes are powered by fossil fuel oil. When the oil is burnt it gives off carbon dioxide gas emissions which contribute hugely to global warming. You can offset this by planting trees to absorb the C0² given off. This is called carbon offsetting. If we reduced the amount of packaging used in products, it might reduce costs and save energy in terms of fuel and transportation.
What can we do? Buy local! This means supporting local growers. It is much better for the environment if you grow and/or buy local organic produce.
What is Fairtrade?
Fairtrade is about better prices, decent working conditions, local sustainability and fair terms of trade for farmers and workers in the developing world. By requiring companies to pay sustainable prices (which must never fall lower than the market price), Fairtrade addresses the injustices of conventional trade, which traditionally discriminates against the poorest, weakest producers.
The Fairtrade Foundation has licensed over 3,000 Fairtrade certified products for sale through retail and catering outlets in the UK. The UK market is doubling in value every two years. The UK is one of the world’s leading Fairtrade markets, with more products and more awareness of Fairtrade than anywhere else. Around 20 per cent of roast and ground coffee sold in the UK retail market is Fairtrade. Stable prices mean that coffee farmers can plan for the future.
Fairtrade food products include:
* bananas
* cocoa
* coffee
* dried fruit
* fresh fruit and fresh vegetables
* honey
* nuts/oil seeds
* rice
* spices
* sugar
* tea.
Organisations such as Traidcraft use only ethically produced materials and ingredients, which helps both the producers and the manufacturers in developing countries. Adriano Kalilii, a tea plucker from Kibena in Tanzania, can afford iron sheets to roof his house thanks to Fairtrade.
Farm Assured
We all want quality food that is affordable and safe to eat. The Red Tractor is an independent mark of quality that guarantees that the food we are buying comes from farms and food companies that meet high standards of food safety and hygiene, animal welfare and environmental protection. Look for the Red Tractor Assurance logo.
Key points
* The Fairtrade mark is an independent consumer label that appears on products as a guarantee that disadvantaged producers are getting a better deal. It guarantees that farmers in developing countries get a fair price for their products, which covers their costs.
* Organic foods avoid health risks associated with a combination of chemicals used as pesticides and herbicides.
