4. Diet Soda
One of the most dangerous items to ever be invented was the diet soda. By trimming certain things from the ingredients list, soda manufacturers guaranteed a giant market share, consisting largely of people who are attempting to be health conscious. Unfortunately, diet soda messes with your body¹s ability to recognize and manage sugar properly. And while diet drinks may be calorie-free, those who drink them are at a much greater risk for weight gain than those who do not.
