I never said that people "need" sugar. A physiological amount is at least 1-2 pounds at once (1 kilogram) from a fasted state, probably more though depending on context, I actually forgot since it's been a while since I looked at those studies. Most anything has an intake level at which it becomes harmful or toxic. Nobody in the world consumes a toxic amount of sugar because it makes you physically ill.

Oh OK. Yeah the petrol explains it. It's true that sugar and potatoes are both carbohydrate sources.
Refined sugar is empty calories because it contains no fiber, minerals, vitamins or other nutrients. Potatoes do contain those. So if you eat a lot of refined sugar every day you actually run the risk of nutritional deficiency. Many Westerners have an inadequate intake of several minerals and vitamins in part because they consume too many empty calories (oil, butter, animal fat, refined sugar etc.)
