Document Summary

Uses energy-yielding nutrients as: fuel supports all body activities (carbs); storage for later use (proteins, fats), ra(cid:449) (cid:373)aterials for (cid:271)uildi(cid:374)g the (cid:271)od(cid:455)"s tissues a(cid:374)d regulati(cid:374)g a(cid:272)ti(cid:448)ities (cid:894)parti(cid:272)ularl(cid:455) protein). Body goes through stage-utilization cycles; storage sleep wake up. No proper way to store protein: nitrogen = toxic; body gets rid of it (humans get rid of it through urea); therefore, it is(cid:374)"t a(cid:374) a(cid:373)i(cid:374)o a(cid:272)id (cid:449)ithout (cid:374)itroge(cid:374). Essential, organic molecules; classified according to solubility in water or fat. 13 vitamins: water solu(cid:271)le (cid:894)b (cid:272)o(cid:373)ple(cid:454), c (cid:895), fat soluble (a, d, e, k). Inorganic; 14 essential: major minerals (>100 mg): calcium, phosphorus, potassium, chloride, sodium, Magnesium, sulphur: minor minerals (<100 mg): iron, iodide, zinc, chromium, Bind to substances; prevents being absorbed into the body. Science of nutrition: study of nutrients and how the body handles them. Nutritional genomics study of how nutrients affect the activities of genes and how genes affect the interactions between diet and disease.
