Calcium Deficiency ⚫ Rickets results in poorly formed bone structure and causes bowed legs, “pigeon breast,” enlarged wrists or ankles, and stunted growth. ⚫ “Adult rickets” (osteomalacia) causes bones to become soft. ⚫ Osteoporosis causes brittle bones. ⚫ Tetany, characterized by involuntary muscle movement, results from insufficient calcium in the blood. Calcium Excess ⚫ Excessive intake may: Cause constipation 48 Cause kidney stones ⚫ Symptoms of deficiency include bone Inhibit the absorption of iron and zinc demineralization (loss of minerals), fatigue, and anorexia. Potassium (K) ⚫ Found primarily in intracellular fluid ⚫ Essential for fluid balance and osmosis ⚫ Maintains fluid level within the cell ⚫ Necessary for transmitting nerve impulses and muscle contractions Potassium Sources Phosphorus (P) ⚫ Constituent of all body cells ⚫ Necessary for the formation of strong, rigid bones and teeth; metabolism of carbohydrates, fats, and proteins; proper acid-base balance; and effective action of ⚫ Fruits: especially melons, oranges, bananas, several B vitamins and peaches ⚫ Vegetables: mushrooms, Brussel sprouts, Phosphorus Sources potatoes, tomatoes, winter squash, lima beans, and carrots Potassium Deficiency and Excess ⚫ Deficiency = hypokalemia ⚫ Stored in bones; absorption is increased in the presence of vitamin D ⚫ Protein-rich foods such as milk, cheese, meats, poultry, and fish ⚫ Cereals, legumes, nuts, and soft drinks Phosphorus Deficiency ⚫ Deficiency is rare. ⚫ Excessive use of antacids affects absorption. 49 Caused by diarrhea, vomiting, Sodium Sources diabetic acidosis, severe malnutrition, or excessive use of laxatives or diuretics Symptoms include nausea, anorexia, fatigue, muscle weakness, and heart abnormalities ⚫ Excess = hyperkalemia ⚫ Table salt contains 40% sodium. ⚫ One teaspoon of table salt contains 2,000 mg of sodium. ⚫ Naturally available in animal foods ⚫ DRI for sodium is 1,500 mg. ⚫ Tolerable upper limit is 5,800 mg, which is easily exceeded by the general population. Sodium Deficiency Caused by dehydration, renal failure, excessive intake Cardiac failure can result. ⚫ Caused by severe vomiting, diarrhea, and Sodium heavy perspiration ⚫ Can upset the acid-base balance ⚫ Primary function is the control of fluid ⚫ Tetany resulting from alkalosis can balance in the body develop. ⚫ Maintains acid-base balance ⚫ Participates in the transmission of nerve impulses essential for normal muscle function 50 Sodium Excess ⚫ May cause edema and resulting hypertension ⚫ Associated with hypertension and congestive heart failure ⚫ Treatment includes sodium-restricted diets; 3–4 g (no added salt, or NAS) or 1– 2 g sodium-restricted diet. Diets below 1 g are rarely prescribed.
