The ingredients of stevia
The steviol glycosides are the most important and also the most popular ingredients of the Stevia rebaudiana Bertoni plant. They belong to the secondary carbon compounds, since they belong to the so-called diterpenes. The rebaudioside A, C, D, E and dulcoside A and stevioside have been classified. The rebaudioside A and C take a 2-4 or 1-2% of the plant mass and Stevioside 2-10% of the plant mass and thus have the largest share in the sweetness. The proportions can vary from plant to plant.
Rebaudioside A has the most neutral of all steviol glycosides sweetness, while in the other a bitter taste may occur with the consumption of high doses.
Without calorie sweetener
The special structure of steviol glycosides leads to the Stevia products have virtually no calories. Carbon compounds are compounds in which a sugar molecule is linked with alcohol. The glycosides are compounds. The Steviolglykosid connections have a sugar content (glucose molecules), which the body can not fully exploit. 100mg of pure Steviolglykosid have a significantly higher sweetening power than the normal table sugar, but only half a calorie. If you want to achieve this sweetness with the conventional sugar, so you need 30g for it and in addition has a caloric intake of 125 calories.
The carbohydrates from the stevia leaves and teas also not lead to a negative energy balance, because the glucose molecules do not enter the blood, because they are not digested in the gut, because they occur as herbal substances structure. However, carbohydrate-containing fillers or excipients may be present in stevia powder, stevia tablets and stevia granules, which are used to guarantee a certain consistency of the products. On the daily consumption of stevia, the carriers but have no effect on the energy balance, nor in diabetics. Of course, the additives for improving the consistency in quality stevia products are found in much smaller proportions.
Journal of valuable ingredients: oils and proteins
The Stevia rebaudiana Bertoni but still carries other valuable ingredients. The sheet contains example, unsaturated fatty acids, and components for protein, and proteins and "empty" fats. This ratio of oils and proteins is the secret for skin firming effects of stevia.

Especially good are the minerals for the cardiovascular system, for bone formation and porosity against the bone and also important for blood formation. Not insignificant these minerals are for the immune system.
Trace elements: some vital trace elements like zinc and selenium are found in the products of the stevia plant. However, other trace elements such as manganese, silicon, cobalt, or chromium, which are involved in the enzymatic processes. That is, they provide the function of the excretory system, the utilization of oxygen and the physiological assembly and disassembly of energy safely.
Vitamins: Vitamin C is very important for the defense against infection and is the most important vitamin that is present in Stevia. Also important in the plant and contain the vitamin beta-carotene (supports the process of seeing) and B1 (the "nerve vitamin)
But that's not all, has to offer stevia, there are other ingredients that are of interest to folk medicine for centuries. For example, there are the flavonoids, which are plant compounds that support the immune system. Among the proven 7 flavonoid compounds is also rutin. Rutin is mainly used in large quantities for circulation problems or venous disease.
