STEVIA A NATURAL SWEETENER
Stevia, a natural sweetener without calories
The discovery of the properties of stevia as a sweetener has been a real revolution in the world of food.
In some countries like Japan, 49% of sweeteners that are ingested correspond to products made from this plant.
The main advantage of stevia from sugar and other simple carbohydrates is having a superior sweetening capacity, and also is substantially free of calories.
One gram of sugar contributes with four calories while stevia has only about 0.2 kcal per gram. However, it is considered that the leaves of this plant can sweeten 20 to 30 times more than sugar.
Stevia extract, used as a natural sweetener, has a higher sweetening power than stevia leaves.
Stevia does not cause tooth decay.
Why is stevia taste sweet?
Stevia does not contain sugar. The reason for its sweetening power is because in its composition become part a series of components that provide sweetening properties.
Although stevia contains sucrose, that is to say, sugar, the proportion thereof is extremely low.
It also contains traces of anethole, but its sweetening power is mainly due to a combination of dulcoside A, differentstevioside and rebaudioside, the main natural sweeteners.
Among them, component rebaudioside A is the one that has greater sweetening power, being 242 times sweeter than sucrose (table sugar), followed by Rebaudioside component D which is 221 times sweeter and stevioside (sweetener component most used), which sweetens 210 more than sugar.

Advantages of stevia to sugar
There are several advantages offered by stevia sweeteners to sugar or other simple carbohydrates:
Stevia for diabetes
Stevia is a sweetener suitable for diabetics: Although there is no conclusive evidence on this, studies suggest that this type of sweetener is well suited for diabetes mellitus, since it manages diabetics to be more tolerant to glucose, and levels remain more stable.
Especially it has been shown that components of stevia could be very beneficial for the treatment of type 2 diabetes (adult diabetes), for their hypoglycemic properties.
Stevia for obesity
Stevia is a calorie-free sweetener. It can reduce the calorie content of sweet food without sacrificing flavor. With stevia can be prepared sweets, desserts, smoothies or sweeten any preparation, without adding calories to the dish.
Since the caloric power of the stevia sugar is virtually zero, we can use to sweeten foods without eating extra calories. In addition, stevia does not cause tooth decay.
A remedy to remove the craving to eat: The problem of sugar and other foods high in simple carbohydrates is the "rebound effect" they produce. High-sugar foods are responsible for the urge to eat that occurs after a while eating them.
The reason, in addition to stress, is mainly due to the impossibility for foods high in simple sugars to maintain levels of blood glucose stable, reason why the body asks us to eat some more sweet.
Using sweeteners like stevia, instead of sugar, helps reduce food obsession. (See more information about "sweet cravings")
Natural and artificial sweeteners for the intestinal flora
Recently it has been published a study in which it was analyzed the intestinal flora of consumers of the three most commonly used artificial sweeteners: saccharin, aspartame and sucralose (Splenda)
Initial results showed that the use of these sweeteners produced changes in the intestinal flora, so the body had more difficulty regulating sugar levels in the blood, increasing the risk of obesity and diabetes.
In that sense, stevia is presented as an alternative to using artificial sweeteners (those not found in nature).
