Stephan Guyenet har skrivit ett långt inlägg om socker och hur det påverkar kroppen. Som vanligt är det mycket genomtänkt och intressant.

Vad han kommer fram till? Det naturligtvis inte så enkelt att man kan dra allt socker över en kam.

Here are the take-home points from this post:
1. Sugar, including fructose, is not inherently fattening relative to other calorie sources, and unrefined sugar is compatible with fat loss in the context of simple whole food diets.
2. Sugar can be fattening in certain contexts, specifically if it is added to foods and beverages to increase their palatability, reward value and energy density.
3. Sugar-sweetened beverages are probably one of the most fattening elements of the modern diet.
4. Fruit is not fattening, and it may actually be slimming.
5. In excess, refined sugar can cause body fat to redistribute from the subcutaneous depot (under the skin, where you want it) to the visceral depots and the liver (where you don't want it). It can also cause insulin resistance in the liver and increase blood pressure, all components of the 'metabolic syndrome'.  This is caused specifically by the fructose portion of the sugar.
