鈥淪OFT drink intake is related to poor nutrition and raised risk for obesity and diabetes.鈥� So says Kelly Brownell, director of the Rudd Center for Food Policy and Obesity at Yale University, whose team has reviewed 88 studies on the effects of soft-drink consumption in a systematic trawl through the evidence.
Of 21 studies that met the most rigorous methodological standards, 19 showed that people who drank the most soft drinks also took in the most calories overall (American Journal of Public 午夜福利1000集合, vol 97, p 667).
Part of the problem seems to be that sugary soft drinks don鈥檛 make people feel full. 鈥淲ith soft drinks, it seems that the calories are invisible to the body,鈥� says Arne Astrup of the University of Copenhagen in Denmark, a veteran of research on soft drinks and obesity.

A study by Astrup published last week in the British Journal of Nutrition (vol 97, p 579) showed that people ate far less after drinking cocoa-based drinks than after carbonated soft drinks.
The argument over whether sugary soft drinks have been contributing to the rise in obesity in western countries has been raging for years, and the American Beverage Association claims that Brownell鈥檚 review has picked on soft drinks unfairly.
Brownell agrees that obesity has many causes. 鈥淏ut you must start somewhere,鈥� he says. He argues that soft drinks and the vending machines used to dispense them should be banned from schools.
