In recent years, there has been a steady assault on salt on from the doctors: salt is bad for you—regardless of your health. Politicians also got on board. "There is a direct relationship," U. S. congressman Neal Smith noted, "between the amount of sodium a person consumes and heart disease, circulatory disorders, stroke and even early death. "
Frightening, 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. "For most of us it probably doesn’t make much difference how much salt we eat. " Dustan’s most recent short-term study of 150 people showed that those with normal blood pressure underwent no change at all when placed on an extremely low salt diet, or later when salt was reintroduced. Of the hypertensive subjects, however, half of those on the low-salt diet did experience a drop in blood pressure, which returned to its previous level when salt was reintroduced.
"An adequate to somewhat excessive salt intake has probably saved many more lives than it has cost in the general population," notes Dr. John H. Laragh. "So a recommendation that the whole population should avoid salt makes no sense. "
Medical experts agree that everyone should practice reasonable "moderation" in salt consumption. For an 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 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 causes hypertension". In fact, there is increasing scientific evidence that other factors may be involved: deficiencies in calcium, potassium, perhaps magnesium; obesity(much more dangerous than sodium); generic predisposition; stress.
"It is not your enemy," says Dr. Laragh, "Salt is the No. 1 natural component of all human tissue, and the idea that you don’t 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. "
What is the main message of this text?
选项
A、That the salt scare is not justified.
B、That the origin of hypertension is now found.
C、That the moderate use of salt is recommended.
D、That salt consumption is to be promoted.
答案
A
解析
由整篇文章可知:本文主要在讲述对于盐的摄入量的恐惧,同时建议盐的食用不可过多,但不吃也是不行的。食盐摄入应保持合理,天4~10克。据此可知,A项“对盐的恐惧是不合理的”正确。
