Re "Don't stop scientific dialogue" (Letters, Aug. 7): The soda industry continues to claim that sodas are equivalent to other calorie-rich foods when it comes to causing obesity and diabetes. This actually is not true.
Although it is true that obesity is the result of consuming more calories than is burned, not all calories are created equally. That is, sodas provide empty calories, which provide no vitamins and minerals, and do not send signals of being full. Whereas, a piece of cake tells your mind to stop eating, sodas do not, so you end up eating more calories than you would have otherwise.
