还真是 potassium chloride http://en.wikipedia.org/wiki/Salt_substitute Salt substitutes are low-sodium table salt alternatives marketed to circumvent the risk of high blood pressure and cardiovascular disease associated with a high intake of sodium chloride[1] while maintaining a similar taste. They usually contain mostly potassium chloride, whose toxicity is approximately equal to that of table salt in a healthy person ( the LD50 is about 2.5 g/kg, or approximately 190 g for a person weighing 75 kg). Potassium lactate may also be used to reduce sodium levels in food products. It is commonly used in meat and poultry products.[2] The recommended daily allowance of potassium is higher than that for sodium,[3] yet a typical person consumes less potassium than sodium in a given day.[4] Seaweed granules are also marketed as alternatives to salt. [5] However, various diseases and medications may decrease the body's excretion of potassium, thereby increasing the risk of potentially fatal hyperkalemia. People with kidney failure, heart failure or diabetes should not use salt substitutes without medical advice. A manufacturer, LoSalt, has issued an advisory statement[6] that people taking the following prescription drugs should not use a salt substitute: amiloride, triamterene, Dytac, captopril & other angiotensin-converting enzyme inhibitors, spironolactone, aldactone, eplerenone, and Inspra. Hydrolyzed protein[7] or 5'-nucleotides[8] are sometimes added to potassium chloride to improve the flavour of salt substitutes. Potassium chloride may have a metallic taste to some.[9]

不对。目前大部分专家是提倡多吃钾。目前没有上限,一般至少每天4.7克 带心型图案的对心脏有帮助的食品都必须有一定钾。 The Institute of Medicine has set an adequate intake for potassium. Getting this amount of potassium from diet, with or without supplements, should be enough to keep you healthy. The FDA has determined that foods that contain at least 350 milligrams of potassium can bear the following label: "Diets containing foods that are good sources of potassium and low in sodium may reduce the risk of high blood pressure and stroke." There is no set upper limit for potassium. So it's not clear exactly how much potassium you can take safely. However, very high doses of potassium can be deadly.
