Elements are inorganic and needed by the body as structural components of. Minerals bone, regulators of enzymes, chemical reactions and other body processes. Diet composition and nutrient interactions (mineral form is important) Minerals needed in diet in amounts greater than 100 mg/day. Even through absorption rates for sodium, chloride, and potassium are high, Electrolytes their levels in our blood and tissues are well maintained, in part, through our thirst mechanism and well functioning adrenals, liver and kidneys. Al for sodium, 1500 mg/day to ensure adequate intake of other nutrients and. Also the food grouping that contributed the greatest amount (-20%) of sodium to. Most sodium in diet as salt--> 75% of which comes from processed foods, 15% Essential for maintaining fluid balance, most found in extra-cellular fluid and is actually pumped out of cells; needed for glucose absorption, muscle contraction and nerve transmission (salt cured foods) Also a strong positive relationships between high salt intake and stomach cancer.
