Stevia is not an artificial sweetener! It is an all natural product.
Stevia is a relatively new word in modern culture. Stevia is a sweetener extracted from the leaves of the plant Stevia Rebaudiana. It is zero calories when used in food.
Stevia is more expensive to produce than other sugar substitutes so naturally big food manufacturers are not jumping to embrace this product and subsequently raise food prices to account for the difference in cost. People want cheap food.
If you put quality ahead of quantity then look for foods that have no sugar, no high fructose corn syrup (HFCS) and no other artificial chemical sweeteners.
Stevia is typically packaged in small green envelopes for single serving sizes.
