Basal metabolic rate is defined as the bodys requirement at rest
They catagorise nutritional requirements
Proteins
Needed for:
- Tissue production and repair
- Hormone manufacture
- Fluid balance maintenance
- All seem to reference just material synthesis
Defines essential amino acids in older humans as:
- Leucine
- Isoleucine
- Lysine
- Methionine
- Phenylalanine
- Threonine
- Tryptophan
- Valine
- Histidine States that Arginine is essential in younger humans
Proteins that can be broken down into all of these amino acids are described as complete. Biologically value is a casual scale for describing the adequacy of the protein within a food States that within animals, except for gelatin, all proteins are complete. It is stated that plant protein such as nuts, peas, beans, lentils and soya have a limited number of amino acids. It is stated that older humans should receive roughly one third of their daily requirements as complete protein ot recieve the optimum intake of amino acids.
Vitamins
table 4 of Applied nutrition and dietetics- Joan huskisson ( doubtful of bias towards meat production, hasnt looked into alternatives)
| Vitamin | Major sources | functions | effect of deficiency | chemical and physiological characteristics | recommended daily adult allowance |
|---|---|---|---|---|---|
| retinol ( A) | dairy fats, fish oil, egg yolk, liver | ||||
| carotene | carrots, pumpkin, spinach, broccoli, apricots, yellow peaches | ||||
| thiamine ( B1) | wholegrain products, green leafy veg, milk, meats ( particularly non muscle organs) | ||||
| riboflavin | same as thiamine | ||||
| niacin | green leafy veg, wholegrain cereals, lean carcas, bird carcas, fish carcas, non muscle carcas components | ||||
| ( B12) | milk, carcas, liver, kidneys | ||||
| folic acid | dark green veg, yeast, liver, kidneys | ||||
| absorbic acid ( C) | citrus fruits, tomato-s, potato-s, strawberry-s | ||||
| ( D) | sunlight, margarine, fortified milk, fish liver oil | ||||
| tocopherols ( E) | vegetable oil-s, peas, beans, leafy vegetable-s, wheatgerm | ||||
| ( K) | green leafy vegetables |
non animal production alternatives to ( retinol ( A), ( B12)) needed
Fats
Composed of carbon and hydrogen The most dense form of energy with roughly 37J3 / 1g
