no you don't. https://en.wikipedia.org/wiki/Gluconeogenesis
> Glucose is the primary source of energy for almost every food consuming organism
yeah, those carnivores consume so much carbohydrates!
> Too much sugar is harmful, yes, but don't say things that aren't true.
the problem is with public perception of what is "too much" - it has to be lowered significantly and people have to start counting starches as sugar.
but in any case, you could always argue that fruits are good or starchy vegetables are good in moderation, but none of it will ever apply to table sugar.
