Irrevocable Waiver Law and Legal Definition. An irrevocable waiver is a waiver that can't later be changed or revoked. A waiver or release gives up a right, such as releasing one from his/her liability for harm or damage that may occur from performing under a contract, or participating in an activity.
Although you should limit added sugars in your diet, you don't need to limit natural sugars in food, as these sugars are found along with fiber, vitamins and minerals. Potatoes contain three main types of sugars: fructose, sucrose and glucose.
Russet, red and white potatoes share similar sugar and starch profiles. One medium potato has 2 grams of sugar and 23 to 30 grams of starch. Sweet potatoes have more sugar -- 7 grams -- but about the same amount of starch. When they're digested, both carbohydrates are broken down into the simple sugar glucose.
