Nutrients are molecules in food where all organism need to make energy to grow and develop Nutrients are digested and broken into basic parts so that the organs can make use of them Nutrients are of two main types Macronutrients and micronutrients where the macro and micronutrients are subdivided. All these nutrients enrich our organs and give a healthy life. The value and range of nutrients in our body depend upon age. Nutrients perform a various function in our body like energy provision and processes like digestion, breathing, growth and development. The requirement of energy depends upon age, size and activity level. If the intake is equal to the amount of energy then the energy is in balance level.
BMI (body mass index) is a very good indicator of nutrition status. The calculation is done by considering height, weight and total body fat as weight
BMI = weight (kg)/height * height
If the value is high then it indicates that the fat storage is high and low value indicates insufficient fat. Therefore BMI can be used as a diagnostic tool for both over nutrition and under nutrition.
If BMI lies between 25.0 and 29.9 then it means your overweight and if it is above 30.0 it means yours are obese The healthy BMI range is between 18.5 -24.9.
BMI can also underestimate the amount of body fat for an elderly person and also for people who are physically disabled.
It can also overestimate the weight for athletes, bodybuilders and pregnant women.
