>You're making an assumption that because glucose is part of the process, it is essential to ingest it through sucrose, fructose, starches, etc.
No, that's not what I'm assuming or implying.
I'm saying because starch is a highly efficient source of glucose, it has nutritional value.
Nobody who are saying citrus fruits have nutritional value because they are high in vitamin C are implying it's essential to ingest vitamin C through citrus fruits. You can't blame a lemon for not being the exclusive source of vitamin C, neither can you blame white bread for not being the only way to increase your blood sugar.
>Starch(in general) is considered a nutrient, but not because it can be used to produce glucose.
What else is it good for but to be converted into glucose?
