Diet sodas are healthier alternatives to regular sodas because they contain fewer calories than regular sodas. But there is conflicting evidence to other health effects of artificial sweeteners in diet sodas. Some of them claim that artificial sweeteners can increase the insulin resistance of the body while according to others, they do not harm healthy individuals. To appeal for health-conscious customers, manufacturers fortify diet sodas with extra minerals and vitamins. Regardless of that, there is no doubt that drinking diet soda regularly is not a healthy habit even though they contain fewer calories.
