Document Summary

Makes up a(cid:271)out 60% of a perso(cid:374)"s weight. 2/3 intracellular fluid, 1/3 extracellular (80% interstitial, 20% plasma) ph of 6. 8<7. 35-7. 45<8. 0. Water intoxication: excessive ingestion of plain water. Urine colour reflects the level of hydration. Diuretics such as coffee, tea and cola increase water loss and may lead to dehydration via inhibition of adh secretion. Thirst and satiety govern water intake: hypothalamus, pituitary gland, kidneys. The correct combination and amounts of electrolytes are essential for life. Distribution of electrolytes affect the distribution of water throughout the body: water follows salt, water flows towards greater concentration. Major part of fluid and electrolyte balance. Essential to muscle contraction and nerve transmission. To keep salt a(cid:374)d (cid:862)water weight(cid:863) u(cid:374)der (cid:272)o(cid:374)trol, dri(cid:374)k (cid:373)ore water. Same sodium intake than a control diet however dash has less salt intake. Control diet: low in fibre, high in total fat and saturated fat.
