Excessive sugar has a strong mal-effect on the functioning of active【46】o______such as the

heart, kidneys and the brain. Shipwrecked sailors who ate and drank nothing but sugar for nine days surely went【47】some of this trauma.

This incident occurred when a vessel carrying a【48】ca______of sugar was shipwrecked in 1793. The five【49】______(survive) sailors were finally rescued nine days after the accident. They were in a wasted condition due to starvation, having consumed nothing but【50】______.

French physiologist F. Magendie was inspired by that incident to【51】co______a series ofexperiments with【52】an______. In the experiments, he fed dogs a diet of sugar and water. All the dogs wasted and died.

The shipwrecked sailors and the French physiologist' s experimental dogs proved the same point. As a steady diet, sugar is worse than nothing. Plain water can keep you【53】a______for quite some time. Sugar and water can kill you. Humans and animals are "unable to subsist【54】______a diet of sugar". The dead dogs in Professor Magendie' s【55】la______alerted the sugar industry to the hazards of free scientific inquiry. From that day to this, the sugar industry has invested millions of dollars in behind-the-scenes, subsidized science. The best scientific names that money could buy have been hired, in the hope that they could one day come up with something at least pseudoscientific in the way of glad tidings about sugar.
