As the world consciously abandons the love of sugar, there has been an increase in production, along with the sale of low-sugar or sugar-free foods, which may seem like a healthy option, but are they really that good? Sugar-free foods are made with sugary alcohols such as sorbitol, mannitol and xylitol. Sugar alcohols are made by the lab to sweeten the taste, which is not absorbed into the bloodstream. This means you can enjoy the sweet taste without adding calories. These do not raise sugar levels, but can often cause upset stomach or diarrhea. However, experts recommend moderate amounts of sugar-free foods. Also, a compound called aspartame, commonly used as a substitute for sugar in foods, candies and beverages, has been shown to increase the risk of cancer, according to research. In fact, this artificial non-saccharide sweet is 200 times sweeter than sucrose.
