For example, common zero-degree cola and sugar-free chewing gums are using sugar substitutes to replace ordinary sugars and sweetness by adding sugar substitutes.

As a result, many businesses continue to market and promote the concept of selling their “healthy foods”, which has led many people to overtake the sugar substitutes. But is the sugar substitute product as healthy as people think?
