I I ypomagnesemia occurs when the serum magnesium concentration is less than 1.7 mg/dL (1.4 mEq/L). The normal serum magnesium level is 1.7 to 2.7 mg/dL (1.4 to 2.3 mEq/L). An average-sized adult has approximately 25 g of magnesium in her or his body. About 50% of the body's total magnesium is found in the bones, 1% is located in the extracellular compartment, and the remainder is found within the cells. The body's requirement is met by ingesting foods such as meat, milk, and chlorophyll-containing vegetables and fruits. The risk of hypo-magnesemia is 2% in the general population, 10% to 20% in hospitalized patients, 50% to 60% in critically ill patients, 30% to 80% in alcohol-dependent patients, and 5% in diabetic outpatients.

Magnesium is regulated by vitamin D-regulated gastrointestinal (GI) absorption and renal excretion. Magnesium plays an important role in neuromuscular function. It also has a role in several enzyme systems, particularly the metabolism of carbohydrates and proteins, as well as maintenance of normal ionic balance (it triggers the sodium-potassium pump), osmotic pressure, myocardial functioning, and bone metabolism. Deficits of magnesium lead to deficits in calcium, and the two electrolyte imbalances are difficult to differentiate. The hypocalcemia that accompanies hypomagnesemia cannot be corrected unless the magnesium is replaced. Hypo-magnesemia is also a stimulus for renin release, which leads to aldosterone production, potassium wasting, and hypokalemia. Because magnesium regulates calcium entry into cells, consequences of magnesium deficiency include ventricular dysrhythmias, an enhanced digitalis toxicity, and sudden cardiac death. Deficits in potassium and calcium potentiate the dysrhymo-genic effect of low magnesium.

Good Carb Diet

Good Carb Diet

WHAT IT IS A three-phase plan that has been likened to the low-carbohydrate Atkins program because during the first two weeks, South Beach eliminates most carbs, including bread, pasta, potatoes, fruit and most dairy products. In PHASE 2, healthy carbs, including most fruits, whole grains and dairy products are gradually reintroduced, but processed carbs such as bagels, cookies, cornflakes, regular pasta and rice cakes remain on the list of foods to avoid or eat rarely.
