The number of calories in a gram of refined cane sugar is the same as in an equal amount of fructose, the natural sugar found in fruits and vegetables. Ttherefore, a piece of candy made with a given amount of refined cane sugar is no higher in calories than a piece of fruit that contains an equal amount of fructose. The reasoning in the argument is flawed because the argument ['presupposes what it sets out to establish, that fruit does not differ from sugar-based candy in the number of calories each contains', 'fails to consider the possibility that fruit might contain noncaloric nutrients that candy does not contain', 'overlooks the possibility that sugar might not be the only calorie-containing ingredient in candy or fruit', 'presupposes that all candy is made with similar amounts of sugar']
