Daily Nutrition Requirments

General
1

Nutrients are substances that are not synthesized in sufficient amounts in the body and must be supplied by the diet. Requirements for organic nutrients include 9 essential amino acids, several fatty acids, glucose, 4 fat-soluble vitamins, 10 water-soluble vitamins, dietary fiber, and choline. Several inorganic substances, including 4 minerals, 7 trace minerals, 3 electrolytes, and the ultratrace elements,must also be supplied by diet.:winking_face_with_tongue:

ESSENTIAL NUTRIENT REQUIREMENTS :-

  1. energy :- For weight to remain stable, energy intake must match energy output. The major components of energy output are resting energy expenditure (REE) and physical activity; minor components include energy cost of metabolizing food (thermic effect of food, or specific dynamic action) and shivering thermogenesis

  2. Protein :- Dietary protein consists of both essential and nonessential amino acids that are required for protein synthesis. The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine /cystine, phenylalanine/tyrosine, threonine, tryptophan, and valine.

  3. Fat and Carbohydrate :- at intake should total no more than 30% of calories. Saturated fat and trans fat should be limited to <10% of calories and polyunsaturated fats to <10% of calories, with monounsaturated fats accounting for the remainder of fat intake.

  4. Water :- For adults, 1–1.5 mL of water per kilocalorie of energy expen-

    diture is sufficient under usual conditions to allow for normal variations

    in physical activity, sweating, and solute load of the diet.

DIETARY REFERENCE INTAKE AND RDAs -There is particular values for infant, ,adult and child as per body weight and lifestyle

ADEQUATE INTAKE:- based on observed or experimentally determined approximations of

nutrient intakes in healthy people.

tolerable upper level-excessive nutrient intake can disturb body functions and causeacute, progressive, or permanent disabilities. The tolerable UL is the highest level of chronic (usually daily) nutrient intake that is unlikely to pose a risk of adverse health effects for most of the population.

ENGAGING QUESTION - so proper assesment as per gender, weight , age(metabolic and real age), physical activity and intake and output determines the exact portion of meal.

DID WR EVER THOUGHT ABOUT IT?:wink:
