Text 1 In recent years, there has been a steady assault on salt from the doctors: salt is bad for you-- regardless of your health. Politicians also got on board. "There is a direct relationship," US 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 experienced 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 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 rest 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 causes 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 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 mason to give it up. What is the main message of this text

Text 3 Travel is at its best a solitary enterprise: to see, to examine, to assess, you have to be alone and unencumbered. Other people can mislead you; they crowd your meandering impressions with their own; if they are companionable they obstruct your view, and if they are boring they corrupt the silence with nonsequiturs, shattering your concentration with "Oh, look, it’s raining," and "You see a lot of trees here". Travelling on your own can be terribly lonely (and it is not understood by Japanese who, coming across you smiling wistfully at an acre of Mexican butter cups tend to say things like "Where is the rest of your team" ). I think of evening in the hotel room in the strange city. My diary has been brought up to date; I hanker for company; what do I do I don’t know anyone here, so I go out and walk and discover the three streets of the town and rather envy the strolling couples and the people with children. The museums and churches are closed, and toward midnight the streets are empty. If I am mugged, I will have to apologize as politely as possible: "I am sorry, sir, but I have nothing valuable on my person." Is there a surer way of enraging a thief and driving him to violence It is hard to see clearly or to think straight in the company of other people. Not only do I feel selfconscious, but the perceptions that are necessary to writing are difficult to manage when someone close by is thinking out loud. I am diverted, but it is discovery, not diversion, that I seek. What is required is the lucidity of loneliness to capture that vision, which, however banal, seems in my private mood to be special and worthy of interest. There is something in feeling object that quickens my mind and makes it intensely receptive to fugitive might also be verified and refined; and in any case I had the satisfaction of finishing the business alone. Travel is not a vacation, and it is often the opposite of a rest. "Have a nice time," people said to me at my send-off at South Station, Medford. It was not precisely what I had hoped for. I craved a little risk, some danger, an untoward event, a vivid discomfort, an experience of my own company, and in a modest way the romance of solitude. This I thought might be mine on that train to Limon. Travelling companions are a disadvantage, according to the writer, because they ______.
