Artificial sweeteners give you the sweet taste of sugar without its calories and without raising your blood glucose levels. Depending on the brand used, one packet will usually give the same sweetness as two teaspoons of table sugar. There are two classes of artificial sweeteners: noncaloric (non-nutritive) and caloric (nutritive).
