You have gained considerable knowledge about the principles underlying the planning of balanced diets. Let us now look at some more important aspects. We have to remember that balanced diets are:
- individual-specific
- region-specific and
- income-specific
What do we mean by these terms? Why are these important in planning balanced diets? You will find the answers to these questions in the subsequent discussion. A balanced diet is never generalized and suitable for all individuals. It is specific firstly, to an individual of a given age (age-range) and sex. In the case of adults, it is also specific to a given activity level-sedentary, moderate or heavy work. A balanced diet for a sedentary worker (e.g. typist or clerk) would differ from that of a heavy worker (e.g. construction labourer). A balanced diet for an infant would be very different from that of an adult (influence of age). A diet for an adolescent girl would be different compared to one for an adolescent boy (influence of sex).
Secondly, balanced diets are always region-specific. The particular foods available in a region can be used in planning; using others would be impractical and unsuitable. There is no point in including a cereal like ragi in a diet meant for a North Indian because ragi is grown only in the south. A balanced diet for a particular region must reflect the characteristic meal patterns, the social and religious practices of that region. These factors are taken into consideration to ensure that the diet planned is acceptable
Thirdly, balanced diets are income-specific. Balanced diets for an individual of a given age and sex (and activity level where relevant) vary depending on income. A balanced diet would imply the use of all food groups energy-giving, body-building and protective/regulatory - in each and every meal. However, the selection of foods and the amounts in which they are consumed would vary depending on income. As income increases, consumption of cereals reduces and consumption of milk and other animal protein foods, vegetables and fruits, fat and sugar tend to increase. While planning balanced diets for the affluent these trends are kept in mind but excessive amounts of fat and sugar are not recommended. Having more money does not mean spending more on fat, sugar and expensive foods like meat/cheese, nuts and dry fruits. It means consuming the amounts absolutely necessary so as to maintain good health and avoid putting on weight and developing other health problems. Having more money, however, enables a person to add more variety to the diet; unusual foods or foods not locally available can be purchased or ordered from elsewhere. Judicious selection of food is, however, as important for the rich as for the poor. The ultimate aim is alway to meet the nutritional requirements
Let us now study the major steps in planning balanced diets. These are given in the following chart.
Let us now discuss each of these steps.
- Identify the individual and his/her specific characteristics: You know the individual's characteristics and background would determine the type of diet planned. Income, socio-economic background, religion and the region where the, individual stays are also important, as you are aware, in the planning of balanced diets.
- Consult RDls for energy and protein :Generally diets which meet energy and protein needs meet the needs of other nutrients as well if care is taken to include rich sources of vitamins and minerals. Therefore in planning diets the total energy and protein needs are specified first.
- Decide on total amounts of specific groups :The amounts of cereals, fat, sugar, milk, meat/fish/poultry, eggs, pulse,vegetables and fruits to be consumed are decided based on the income. The amount included would be such that RDls can be met for energy and protein. This wilI become clear to you when you study the Practical Manual.
- Decide on number of meals to-be consumed :Meal frequency varies depending on income, the work school schedule and convenience. People belonging to the higher income group consume more meals. Consider the following lists of meals consumed in a day.
- Distributed total amount decided between meals:The total amount of each group decide must be distributed over the day's meals. You will learn how to do this using the Practical Manual.
- Decide on items and their amounts within each group for each meal:The dishes to be included for each meal are decided based on amount of each item in each of the three food groups decided on earlier. For specific dishes to be included specific items are selected from each food group.
