Splenda has been available in Canada for several years and is now available in the United States. Splenda (sucralose) is chemically inert and does not break down as it passes through the body. It can be used more or less measure for measure like sugar. In other words, 1 teaspoon of Splenda tastes like 1 teaspoon of sugar.
