Soft drinks and that is almost the truth for everyone. Sugary foods are always make people drooling, and why is that?

Aspartame is one of them. Aspartame is a nonnutritive sweetener which is accidentally discovered by American scientist J. M. Schlatter in early 1960s, and it has approved for use in many countries, including Canada. Table sugar, yogurt, chewing gums, bread spread, bakeries, salad dressing, and, of course, the soft drinks are all allowed use aspartame as its sweetener. Even though it is nice and low-calorie, but does it mean it is safe? Aspartame, at the most of circumstances, will release three molecules in our blood stream: phenylalanine, aspartate, and methanol, which all are ubiquitous in our food sources. So aspartame should be safe for the majority of population in moderate doses. However people with PKU should avoid that kind of molecules. Aspartame is safe low calories substitute for sugar but, still, you need to drink in moderation. If you want to keep healthy and skinny the only action you can take is a balanced meal with regular exercises. By Tommy Z. Yuan (2015).
