People in China consume 10 grams of salt a day on average, twice the amount recommended by the World Health Organization, and over the past four decades adults in China have had among the highest salt consumption in the world.

Salt intake in China is confirmed to be among the highest in the world, with adults over the past four decades consistently consuming on average above 10g of salt a day, which is more than twice the recommended limit, according to new research led by Queen Mary University of London.

The systematic review and meta-analysis(系统评价和荟萃分析), funded by the National Institute for Health Research and published in the Journal of the American Heart Association,also found that Chinese children aged 3-6 are eating the maximum amount of salt recommended by the World Health Organization for adults (5g a day)while older children eat almost 9g/day. Excessive salt intake raises blood pressure,a major cause of strokes and heart disease, which accounts for approximately 40 percent of deaths in the Chinese population.

The team reviewed all data ever published on salt intake in China (which involved about 900 children and 26,000 adults across the country) and found that salt intake has been consistently high over the past four decades, with a North-South divide.

While salt intake in northern China is among the highest in the world (11.2g a day) it has been declining since the 1980s when it was 12.8g a day, and most markedly since the 2000s.

This could be the result of both governmental efforts in salt awareness education and the lessened reliance on pickled (腌制的) food—owing to a greater year-round availability of vegetables.

However, this trend of decrease was not seen in southern China, which has vastly increased from 8.8g a day in the 1980s to 10.2g a day in the 2010s.

This could be due to governmental efforts being mitigated by the growing consumption of processed foods and out-of-home meals.

These latest results contradict (相矛盾) those of previous studies based on the data which reported declines in salt intake across the country.

【推荐1】A small piece of fish each day may keep the heart doctor away. That's the finding of a study of Dutchmen in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce of salt water fish per day compared to those who never ate fish.

The Dutch research is one of three human studies that give strong scientific support to the long-held belief that eating fish can provide health benefits, particularly to the heart.

Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year. But previous research has shown that the level of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption(消耗)averages more than 3 ounces.

For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish. At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.

During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol(胆固醇)levels.

1. The passage is mainly about___________.
A.the effect of fish-eating on people's health
B.the high incidence of heart disease in some countries
C.the changes in people's diet
D.the daily fish consumption of people in different cultures
2. In which section of a newspaper can we read this passage?
A.AdvertisementsB.Movies
C.Briefs D.Health and Diet
3. We can infer from the passage that there are fewer heart disease deaths________________.
A.in countries of the yellow-skin race
B.in the countries with high consumption of fish
C.in highly-developed countries
D.in the countries with good production of fish
4. The underlined part "this relationship" in paragraph 5 may refer to the connection between____________ and the level of heart disease.
A.the kind of fish eatenB.the amount of fish eater
C.regular fish-eatingD.people of different areas
