Normal and Therapeutic Nutrition 3(2+1)
Lesson 3:Meal planning


Dietetics is a science that deals with the adequacy of diets during normal life cycle and modifications required during diseased conditions.

Menu planning is the process of planning and scheduling intake of meals for general or specific individual requirements.

Nutrient requirement can be defined as the minimum amount of the absorbed nutrient that is necessary for maintaining normal physiological functions of the body.

Recommended Dietary Allowances (RDA) is defined as the nutrients present in the diet which satisfies the daily requirement of all the individuals in a population.

RDA = Requirements + Safety factor

Adequate Intake (AI) is a nutrient recommendation based on observed or experimentally determined approximation of nutrient intake by a group of healthy people when sufficient scientific evidence is not available to calculate RDA.

Balanced diet is one which contains different types of foods in such quantities and proportions that the need for calories, proteins, minerals, vitamins and other nutrients is adequately met and a small provision is made for extra nutrients to withstand short duration of illness / leanness except calories.
