  食物中的纤维无论对谁都是有益的,不过食用纤维的类型有所讲究。一项新的研究得出结论,蔬菜纤维是对抗2型糖尿病的有效防治措施。这项研究由来自澳大利亚悉尼大学的研究学者主持进行,该学者发现,每天食用5克蔬菜纤维的成年人患糖尿病的风险要比其他的人低24%;而70岁以上的食用蔬菜纤维者,其患病风险会较同龄非蔬菜纤维食用者低1/3。

  此项研究以10年为周期,跟踪调查了超过2000人的饮食习惯。研究者还报告说,选用谷类和水果作为食物主要来源的人其身体健康运营情况并不十分理想,他们患2型糖尿病的几率要比那些选用蔬菜纤维作为主要食物来源的人更大。原因可能是含蔬菜纤维多的食物比谷类和水果类食物对血糖水平和胰岛素分泌水平的波动幅度影响更小。研究小组的领导者阿兰.巴克莱称,豆类是最好的纤维来源。

Vegetable fiber a first-rate diabetes defense

We could all benefit from added fiber in our diets. However, it seems the type of fiber consumed is important too. A new study concludes that vegetable fiber is a good defence against type 2 diabetes. The study comes courtesy of researchers at the University of Sydney, Australia, who found that adults eating five grams of vegetable fiber daily were 24 percent less likely than other adults to develop the disease. People over the age of seventy enjoyed a thirty-one percent risk reduction.

The study tracked the eating habits of more than two thousand people over a ten year period. Wow. The researchers also reported that those whose diets contained fiber from mainly cereal or fruit sources did not fare so well - they had a higher risk for type 2 diabetes than those getting lots of fiber from veggie sources. The reason could be that foods high in vegetable fiber produce smaller fluctuations in blood glucose and insulin levels than would cereal or fruits. Lead researcher, Alan Barclay, says legumes are the best fiber source of all.
