Low and no calorie sweeteners (LNCS); myths and realities.

Since their introduction in the market, there has been much debate regarding the health effects of low and no calorie sweetners (LNCS). Therefore, through this review, we aim to establish scientific information about the most commonly used LNCS by the food industry. Key questions about uses, safety, and weight control are reviewed. Scientific evidence revised concludes that LNCS available on the market are safe and no epidemiological relationship has been established with the development of non-communicable diseases, including different kind of cancer in humans. Also, LCNS combined with physical activity and a healthy lifestyle can play a significant role in weight loss and the maintenance of a healthy weight. But non nutritive sweeteners will be helpful only as long as people don't eat additional calories later as compensation. Even more, LNCS represent an additional instrument in the dietary treatment of people with diabetes for metabolic control, without avoiding sweet taste.
