Sweeteners: the benefits and harms of artificial sweeteners

July 26, 2014

 Pamper yourself with exquisite desserts without compromising figure - is it possible? Yes, if you use sugar substitutes. Benefits and harms of these additives cause a lot of controversy among both doctors and consumers. However, every day there are more products to which sweet taste is given no sugar, and other compounds.


Terminological confusion

From the standpoint of the layman, sugar and sweeteners - are one and the same, but scientists believe otherwise.

Sweetener called chemicals which are involved in metabolism.

They also calories as sugar - one gram of a sweetener gives the body 4 kilocalories, but may have more intense flavor, thereby used in smaller amounts. This group includes fructose, sorbitol and xylitol.

Sweeteners - a group of substances that do not participate in metabolism and calorie have zero. Such substances include sucralose, saccharin, cyclamate, and others.


Case history

Open sweeteners were accidentally: legend has it that one day a chemist by the name of Falberg forgot to wash his hands, returned from the lab, and was surprised to find that the bread that he took these hands, has a sweet taste. Now it's hard to say, it all was, but the fact remains that in a short time has been synthesized the first artificial sweeteners - saccharin. Application found him already during the First World War, when the regular sugar has become inaccessible and expensive product.

It would seem that way to combat obesity has been found, but sugar substitutes have not been able to fully replace sugar. In the 70-ies of the last century, scientists have found that saccharin is carcinogenic and provokes cancer in laboratory animals. Over time, the sweetener justified - it turned out that in small doses, it is safe. However, in Canada, for example, it is banned to this day.

Not all simply and with other sweeteners. For example, it was found that the popular sugar substitute aspartame increases the appetite and increases the thirst. This successful producers of soft drinks are aspartame helps them increase sales.

Many questions is the fact that, despite the huge popularity of sugar substitutes in the last 50 years, the number of obese people is not reduced, but rather increased. This suggests that sweeteners do not help you lose weight, and may even cause weight gain.
