Swanson Health Products, Fargo, ND, has introduced PureLo Lo Han Sweetener, a natural, zero-calorie alternative to artificial sweeteners made from the concentrated extract of lo han, a traditional Chinese fruit also known as monk fruit. Because lo han can be up to 200 times sweeter than sugar, Swanson Health Products has tempered the natural sweetness by blending PureLo with natural inulin.
