C篇阅读理解

Rats that eat high levels of a natural sugar known as fructose seem to age faster than other rats----and the same could be true for people who eat too much sweet junk food, Israeli researchers said Monday.

Fructose, found naturally in honey and fruit, is used widely in foods ranging from soft drinks to yogurt. But while its sweet taste is popular, the sugar could cause wrinkles and health the problems, the researchers said. Dr. Moshe Werman and Boaz Levi of the Technion- Israel Institute of Technology fed large amounts of fructose to laboratory rats. Writing in the Journal of Nutrition, they said the fructose-fed rats showed changes in the collagen of their skin and bones.

Collagen, found in connective tissue, and bone, basically holds the body together. The loss of collagen is what makes skin loose and causes deep wrinkles in older people.

According to Werman's team, the process affected is known as "cross linking". "Too much cross-linking encourages wrinkled skin. The same could be true of people, although this has not been shown. "Americans are eating more and more processed foods such as carbonated drinks, baked goods, canned fruits, jams and dairy products that contain fructose." Werman said in a statement. Other studies have shown that high fructose intake can affect how the body handles glucose and increases insulin resistance---- which can both be important measures of the tendency toward diabetes.

The rats Werman worked with were fed much more than the average adult person might eat in a day, which is standard in such experiments. The rats were fed 12.5 grams of fructose per kg of weight every day for a year. To compare, a person weighing 70kg who drinks liter of cola consumes about 60 grams of fructose, or 0.8 grams per kg of body weight.

Rats that eat high levels of a natural sugar known as fructose seem to age faster than other rats.
