Last month we reported about a study that showed eating even a little less salt could greatly help the heart. The study was published in the New England Journal of Medicine. The scientists used a computer model to predict how just three grams less salt a day would affect heart disease in the United States. The scientists said the results would be thirteen percent fewer heart attacks, eight percent fewer strokes , four percent fewer deaths and eleven percent fewer new cases of heart disease And two hundred forty billion dollars in health care savings. Researchers said it could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year. They and public health professionals in the United States are interested in a national campaign to persuade people to eat less salt. Such campaigns are already in place in Britain, Japan and Finland. Michael Alderman is among the critics. He is a high blood pressure expert and professor at Albert Einstein College of Medicine in New York. Doctor Alderman says that eating less salt results in lower blood pressure. But he says studies have not clearly shown that lowering salt means fewer heart attacks or strokes. And he says salt has other biological effects. He says calling for reduction in the national diet could have good effects, but it could also have harmful results. He says there is not enough evidence _ . Another critic is David McCarron, a nutrition and kidney disease expert at the University of California, Davis. He and his team looked at large studies of diets in thirty-three countries. They found that most people around the world eat about the same amount of salt. Most of them eat more salt than American health officials advise. Doctor McCarron says the worldwide similarity suggests that a person's brain might decide how much salt to eat. Both Doctor McCarron and Doctor Alderman have connections to the Salt Institute, a trade group for the salt industry. Doctor Alderman is a member of an advisory committee. But he says he receives no money from... What's the best title of the passage? A) The argument over salt and health. B) Less salt, fewer heart attacks. C) National campaign for less salt. D) Bad effects of salt.

The OK gesture in America and England is given to mean everything is good or well. But in Latin America is looked on as a rude sign. The thumbs up sign in America and most of Europe means that something is good or well done, but it is considered rude in many Asian countries.

One important attraction of walking is its long-lasting appeal. Whereas jogging and aerobic dancing can _ quickly, walking provides a popular activity that seems to endure. Fitness foundations estimate that 35 million adult Americans walk for exercise every day, with at least 15 million walking two or three times a week. Among the most regular walkers are those 65 years and older--evidence that walking is an exercise that lasts. In addition to its many physical benefits, walking, like other physical activities, has a comforting effect on the psyche. Walking can help you to think more clearly and feel more relaxed. It also can be a sociable activity. An early morning walk around the neighborhood provides an opportunity to chat with friends or simply admire the flowers. Or because it does not require a team or even a partner, walking is something you can do on your own time, by yourself, whenever the mood strikes. Easily affordable, all you need to start walking is enthusiasm and a pair of comfortable and sturdy low-heeled shoes. Dr.ChristineL. Wells recommends an Oxford-style shoe with ties for better foot support; she does not recommend sneakers or other "cheapies". If you plan to walk regularly, you might want to invest in a pair of so-called walking shoes. If so, expect to spend at least $35. For walking during the hotter months, early morning or evening hours are best. Clothes should fit loosely and be lightweight and light-colored. Elderly walkers should consider wearing long sleeves, and all Arizonans need to be particularly concerned about skin cancer. Dr. Wells suggests wearing sunscreen as well as a side-brimmed hat to protect your eyes, ears, nose and back of the neck. Walkers also should drink an adequate amount of water. Wells advises drinking an 8-ounce glass of water before you start out, and more when you return. "If you walk four miles or more a day in Arizona, I also recommend that you carry a water bottle," she says. " And water is just fine; you don't need those fluid-replacement or...
