We cannot live without food for more than a few days. Our body needs certain substances called nutrients, which are essential for its proper functioning and for maintaining a healthy nutritional status. The only source of obtaining these nutrients is food which we eat. Food comprises a variety of edible substances but we have to make a wise selection to get proper nourishment for our body. So let us begin by first understanding the definitions of food and nutrition. 1.2 DEFINITIONS OF FOOD AND NUTRITION You all know what we mean by food. Food is something we eat and which can be utilised by our body. The need for food begins with the beginning of life itself because it is only through food that we get essential chemical components for life and growth. The process by which the body utilises food is called nutrition. The food consumed by us is utilised by the processes of digestion, absorption, transport, storage, metabolism and elimination for the purpose of maintenance of life, growth, and normal functioning of organs and 7 \ Food Groups, production of energy. Nutrition is thus a sum total or a combination of all Nutrients and Their Functions these processes by which living beings receive and utilise materials necessary for the maintenance of their functions and growth and renewal of their components. So food plays an important role in maintenance of health. Health is defined by World Health Organisation as ‘‘a state of complete physical, mental and social well being and not merely the absence of disease or infirmity’’. You will learn more about nutrition in this course. FOOD IS WHAT WE EAT WHILE NUTRITION IS THE COMBINATION OF PROCESSES BY WHICH WE UTILISE FOOD You must now be wondering what it is in food that is utilised by our body. Well, while a variety of foods may be available, the basic constituents of all food are only six. These constituents are collectively called nutrients and include water, proteins, fats, carbohydrates, minerals and vitamins. Our body requires these nutrients in adequate amounts to promote good health. Our body’s need for nutrients depends on many conditions/factors such as activity, climate, daily stresses of living, disease, etc. NUTRIENTS ARE CONSTITUENTS OF FOOD AND INCLUDE: WATER PROTEINS FATS CARBOHYDRATES MINERALS VITAMINS The condition of our health as influenced by the utilisation of nutrients is called our nutritional status. Hence the ultimate benefits of good nutrition to everyone of us are health, happiness, efficiency and longevity. You will leam in more detail about nutrients in Units 3 and 4 of Block 2.

But, what we may eat and how we prepare it, are culturally determined. To understand people’s beliefs and habits regarding food we must know the particular society and the way it likes to cook and eat. Even though the food habits change due to many reasons, traditional food habits tend to persist. If we adopt an ecological approach, we may picture a man influenced by several environmental factors. The most intimate of these is his biological environment which is affected by the food he consumes and his state of health and disease. At different levels, there are physical and psychosocial environments in which a number of factors play their role, prominent among these being education, economics and culture. Thus, though the soil and climatic conditions affect food production, availability and preservation, culture determines beliefs and practices regarding food selection and preparation. Education may then further influence these, while the economic factors largely determine the amount and to some extent the quality of food selected and purchased. In the following units we will learn about the specific socio-cultural aspects that affect food consumption at various ages and the physiological condition of women and children. Practical Activity 1 From your own experience and through discussion of your neighbour's experience, list factors which affect food selection: ………………………………………………………………………………… ,………………………………………………………………………………... ………………………………………………………………………………… ………………………………………………………………………………… ………………………………………………………………………………… 1.4 FACTORS DETERMINING FOOD ACCEPTANCE The subject of food acceptance is a complex one as we are not completely rational either in our acceptance or rejection of food. You would have realised that few aspects of living are as likely to be emotionally charged as those associated with food. So the presentation of well prepared, highly nutritious food before us does not mean that we will accept it. Let us see what factors influence our acceptance of food. These factors could be physiological, socio-cultural and psycho-social. 1.4.1 Physiological Factors Influencing Food Acceptance i) Hunger : People who are in starvation will usually (but not always) accept anything edible that will fill the stomach. The food they accept 10 \ might even be something that they would normally dislike. It is also true Food and Food Acceptance that some people may refuse food even when they are actually hungry, if the food offered does not conform to their cultural or religious - acceptance pattern. You would have observed even in your own behaviour, that you do not choose by instinct what is best for you. You eat what is available and learn through experience that some foods are better for you than others. You also learn how to make several preparations and enjoy eating them. ii) Sensations produced by food: The palatability of food is a combination of taste, aroma, texture and temperature. It is also conditioned by the surroundings in which we eat. We often accept or reject food because of its tempting aroma or repulsive smell. However, it is also true that there are some smells which we enjoy while others dislike them. The sense of touch is highly developed in our tongue. Our tongue enjoys a variety of textures, temperature and taste. Some persons like dry, crisp food, while others may enjoy soft and creamy food, Adults may enjoy steaming hot food while children may enjoy lukewarm food. Similarly, some of us may enjoy hot, sour and salty food whereas others may enjoy bland and salty or sweet and creamy food. These, individual likes and dislikes of food govern our acceptance or rejection of food. iii) Age: Age influences our choice of food to a large extent. For example, peanut chikki, cake, milk etc. are considered foods for children while tea and coffee are considered to be adult foods. While the younger age group enjoy rich food the older age group prefere light meals. 1.4.2 Socio-cultural Factors Influencing Food Acceptance i) Role of culture: Circumstances in which we eat are largely determined by our culture. Food habits may have existed in people through centuries and such a heritage can lead to conservatism in accepting change. These patterns reflect the social organisation of the people including their economy, religion and beliefs about the health and properties of food. You must have noticed that an emotional reaction to the consumption of certain foods may be so deeply rooted that developing acceptance of them is almost impossible. However, it is not just certain foods but even our meal patterns that are dictated by cultural and occupational patterns. Because of the change in our working schedules, some of us have a light breakfast before going for work, while others have a heavy meal. Similarly, when we return from work, some of us prefer a heavy dinner, while others prefer a light one. ii) Social value of food : Do you enjoy eating food alone? Certainly not, not always. We usually enjoy eating food in company. Whatever be the occasion, eating together always provides a friendly atmosphere and enjoyable conversation as we invite people to our homes and go out to the houses of our friends. You must have noticed that certain foods like meat, fish, chicken, or cheese, kofta and rich curries or expensive fruits and vegetables, fancy dessert preparations and a variety of cereal preparations like pulao, nan, paranthas form regular items of the menu on the table for any festive occasion. This is due to the social value attached to such foods. Costly foods like apples, cashewnuts, biscuits are 11 \ Food Groups, considered prestige foods while green leafy vegetables and ragi are Nutrients and Their Functions considered poor man's food. iii) Religious and moral values of food: Almost all religions place some regulations on the food we consume. Certain foods are forbidden by religious regulations. For example, Hindus do not generally eat beef; similarly, Buddhists and Jains do not eat flesh foods or eggs while Islam forbids consumption of pork. Fasting again is common to all religions and certain foods are considered as fasting foods. Again, foods such as milk, cheese, etc. are accepted as “good” foods while papaya is considered a taboo in some communities. In tribal and hill regions, alcohol is a festive offer. Certain foods like sweets are regarded as rewarding foods or foods for celebration, while depriving a person of food is an accepted form of punishment. 1.4.3 Psycho-social Factors Influencing Food Acceptance Food is a symbol of security for all of us. Milk, the first food we take, is usually associated with security. Have you noticed that when you were ill and away from home, you liked to drink milk because it reminded you of the loving care your mother provided you? or, do you remember refusing milk in preference to tea or coffee just because you felt you are an adult? We also at times refuse food because we are angry with our parents or friends or when we are in sorrow. When we are happy we enjoy food. Occasionally, in order to gain attention, when we are sick or lonely, we impose unreasonable demands for food on parents, siblings or friends who are looking after us. Children are reported to have refused food when they are in a state of shock due to a disaster, as in wartime.

Various foods that we eat are utilised by our body through a number of processes like ingestion, digestion, absorption, transport and metabolism. A combination.of all these processes by which the ingested food is utilised by our body is 13 \ Food Groups, called nutrition and the state of nutrition of our body is called nutritional Nutrients and Their Functions status. Food that we eat is made up of nutrients which include water, proteins, fats, carbohydrates, minerals and vitamins and they are required by the body in specific amounts depending upon age, sex, activity, climate, etc. What we eat is governed by our socio-cultural environment, educational level and economic conditions. All foods are not acceptable to everyone. There are individual variations in acceptance or refusal of food. The basic factors determining the acceptance of food are physiological ones which include hunger and sensations produced by food; and social and psychological factors which include role of culture, social values, religious and moral values, age and sex and also the emotional outlet or security provided by food. 1.6 GLOSSARY Absorption : Process by which nutrients are taken into the blood stream. Culture : : Accepted practice in a community. Digestion : Break down of a food in the body by digestive juices, so as to convert it to such a form which can be absorbed in the body. Health : Physical, mental and social well-being. Hunger : Desire to eat food. Metabolism : Process of utilisation of food for internal body processes. Puberty : Period when secondary sexual characteristics develop and sexual reproduction becomes possible. Psychological : Pertaining to the mind. Social : Pertaining to human relations. 1.7 ANSWERS TO CHECK YOUR PROGRESS EXERCISES Check Your Progress Exercise 1 1) Food is something we eat and which can be utilised by our body while nutrition is the process by which we utilise food. 2) State of our body as influenced by the kind of food we consume and utilize is called nutritional status e.g. weight or height. 3) Nutrients are basic constituents of food which promote good health. 4) Carbohydrates, fats, proteins, minerals, vitamins and water are nutrients. 14 \
