Yes. Red blood cells literally can only eat glucose. Without it you would be super dead.
I find it amusingly absurd how so many people here seem convinced that our primary food source is somehow a poison. People with 0 carbs in their blood are colloquially known as 'dead'.
I wonder if people even know what ketone bodies are... They are a downstream product of glucose processing(also downstream of fats - the inputs are different but the outputs are identical in a few ways), acetyl-coA, stuck together for bloodstream transport with the coenzyme temporarily removed.
Glucose is definitely food for humans, I think what the discussions here and more generally in nutrition are about lately is where it should come from. Carbs are the only nutrient with a minimum daily intake of zero. Carbs are optional, as to your point, your liver will synthesize all you need to exist or you would be dead. What that process doesn’t come with as much of is a direct spike in insulin and insulin has a lot of downstream effects.
