Fruit Smoothies

The article rejects fruit smoothies as a gentle way to break a fast. A concentrated fructose load after fasting can be converted into fat through de novo lipogenesis. Fructose travels directly to the liver because it is not processed through the same pathway as glucose. A smoothie's glucose fraction can sharply raise blood glucose and trigger an insulin surge. A typical fruit smoothie contains 40 to 60 grams of sugar, mostly fructose.
