This is not the first time I’ve seen this, and it’s misleading. Your brain needs glucose, as does the rest of your body. You do not need to eat glucose, your body can synthesize it from non-glucose sources. You can absolutely survive on a diet with 0 glucose.

I don’t have an issue with people eating sugar, but it is not a necessary nutrient.

Does your brain necessarily *need* HFCS/sucrose, or will it work with wholegrain diet, fruits, vegetables, legumes?

It just seems that you're arguing that without added, pure sugar in drinks/foods your body and brain would break down, but that would be factually incorrect*

*unless you're also suffering from some exceedingly rare genetic conditions affecting certain metabolic paths but it's unlikely you'd live to tell the story.

when people talk about sugar in the unhealthy context, they are referring to things like how a single can of dr. pepper has 40-50 grams of sugar in it.

Are you diabetic? If you aren't diabetic, your body can manage its own sugar.

You mean, like hyperglycemia?
