Document Summary

In modern times, we eat too much salt, leading to problems like high blood pressure: we may lose sodium through diarrhea, sweating. Resulting in low ecf volume, low bp, shock: we may retain sodium in conditions like heart failure. Results in edema, weight gain, breathing problems. Normal and recommended sodium intake (is too much bad?: a high salt diet risks cardiovascular disease and stroke. If it tastes good, it"s probably high in salt : mainly processed foods (75%, breed, cheese, soups, sauces, meats (packaged meats like ham, bologna), restaurant meals, very little salt added to home cooking or at the table. Sodium balance and the kidney: normally sodium in the diet 100% sodium in the urine (urine sodium excretion = dietary. Sodium in urine 50% sodium intake) If we wanted to know how much sodium we"re eating, have a timed" urine test. If you have other conditions like diarrhea and sweating. Absorb almost all sodium in our diet.
