20、, if true! But many doctors and medical researchers are now beginning to feel the salt scare has gone too far. All this hue and cry about eating salt is unnecessary, Dr. Dustan insists.

Laragh. So a recommendation that the whole population should avoid salt makes no sense. Medical experts agree 。

23、 that everyone should practice reasonable moderation in salt consumption. For the average person, a moderate amount might run from four to ten grams a day, or roughly 1/2 to 1/3 of a teaspoon. The equivalent of one to two grams of this salt allowance would come from the natural sodium in food. The r 。

24、est would be added in processing, preparation or at the table. Those with kidney, liver or heart problems may have to limit dietary salt, if their doctor advises. But even the very vocal low salt exponent, Dr. Arthur Hull Hayes, Jr. admits that we do not know whether increased sodium consumption cau 。

25、ses hypertension. In fact, there is growing scientific evidence that other factors may be involved: deficiencies in calcium, potassium, perhaps magnesium;
obesity (much more dangerous than sodium);
genetic predisposition;
stress. It is not your enemy, says Dr. Laragh. Salt is the No. 1 natural compo 。

26、nent of all human tissue, and the idea that you dont need it is wrong. Unless your doctor has proven that you have a salt-related health problem, there is no reason to give it up.36.

31、is not just some passing trend. Today it is an overarching international system shaping the domestic politics and foreign relations of virtually every country, and we need to understand it as such. As thoughtful people concerned about world affairs, our job is to pick up globalization, examine it fr 。

32、om all sides, dissect it, figure out what makes it tick, and then nurture and promote the good parts and mitigate or slow down the bad parts. Globalization is much like fire. Fire itself is neither good nor bad. Used properly, it can cook food, sterilize equipment, form iron, and heat our homes. Use 。
