THE ROLE OF NUTRITION IN BODY COMPENSATION

Mr. Mallikarjun, Mr. Vijaykumar S D

Abstract

Body composition data are used to evaluate nutritional status, growth and development, water homeostasis, and specific disease states. Human body composition is
studied at atomic, molecular, cellular, tissue, and whole body levels. The levels are interrelated. A “normal weight” human body consists of approximately 98% oxygen,
carbon, hydrogen, nitrogen, and calcium; of 60–70% water, 10–35% fat (depending on gender), 10–15% protein, and 3–5% minerals. The variation in body composition
between individuals is large, mainly because of variations in fat mass. Variations in fat-free mass are smaller. Several direct, indirect, and doubly indirect techniques
are avail-able to measure body composition, each with its own distinct advantages and disadvantages. The choice of method will be influenced by the availability
of instrumentation, invasiveness, and radiation danger to subjects, price, accuracy required, and application objectives .Interpretation and application of data from
body composition measurements should be carried out with care and should take into account the limitations of the method used, age, gender, and ethnic group
