No Nutrition

There's no nutritional value to any soda, really. A lot of people think that drinking diet soda is the same as water, since you're not taking in any calories. This is wrong, though. The aspartame causes issues all over your body, and it's not worth it at all. If you're thirsty and want something low-calorie, just drink water. "Water is essential for many of our bodily processes, so replacing it with diet soda is a negative thing," Bjork says. If it's the fizz you crave, there are a lot of sparkling waters you can try.
