Did the drop in sales across the industry make them think? The fact is that the gentlemen of the Pepsi company are now changing the sweetener in the light version of the famous drink , a direct competitor of Coca-cola. No to aspartame , judged (but this is not scientifically proven, there are studies that have simply established a correlation) a dangerous sweetener for health and yes to safer sweeteners for health.
So will Pepsi light now be safer? Here, the problem is this.No. Although Pepsi forgoes aspartame, Pepsi light as well as Coke light and other light drinks have one terrible thing in common: they are light. The use of a zero calorie sweetener, of any nature, has been linked to the risk of metabolic syndrome (i.e. overweight, diabetes and so on). In fact, the body releases insulin on response of the sweet taste registered by the brain. It releases it empty, since we do not take sugar with the drink, but it releases it. And the problem is that if the reaction of the sweet taste (i.e. the release of insulin) does not correspond to an effect of the sweet (i.e. a response of the blood sugar to the sugars), the deception ( a drink that is sweet but does not give sugar to the body )seems to have an effect on the regulation of the hypothalamus as the center of appetite . People who use light drinks tend to be more hungry for sweets, for example, and this could be the consequence of a body “deceived” by the fake sweet taste of the sweetener.
Furthermore, it is precisely the drink with the sparkling X and Y flavor, soda in English,  that can cause problems of overweight in the habitual consumer.
In short, if we look closely at the change, whether it is aspartame or any other type of sweetener, the problem is upstream: in the product.
Which should be avoided if we want to lose weight.
