Depends on what you mean by “basic groceries.” Produce and generally anything that is not processed or prepackaged is ok, but most anything ready to eat, including any baked goods is likely to be pretty high in sugar.
And just FYI, since glucose, fructose, and sucrose are all naturally occurring, they (and HFCS) are considered organic legally
Correct. However, there are many ways to get glucose into the brain that are not dependent on eating glucose directly. For example, starch and cellulose are both big long chains of glucose molecules linked together, although no multicellular organisms have the necessary enzymes to break down cellulose into glucose (at least none of which I’m aware, anyway).
For the most part, getting your glucose by breaking down starch is healthier than eating it directly, because it slows down the introduction of starch into the bloodstream which keeps your blood sugar levels more stable, since the enzymes that break down starch (α and β amylase, IIRC) don’t do it instantly. Plus, other simple sugars can easily be converted by the buddy into glucose by a variety of enzymes find naturally in the body.
But even without eating any carbohydrates, the human body had the ability to create its own glucose via a process called gluconeogenesis, which occurs mainly in the liver. So, it’s not generally advisable to eat too much sugar directly, as there are plenty of other avenues through which the body can get its glucose, and eating the glucose directly leads to a much higher chance of developing diabetes later in life, even if you remain at a healthy weight.

This is exactly my point: glucose, fructose and sucrose are not unhealthy. They are just fine. Unless one exceeds. Glycemic index is relevant. Eating a bit of sugar sometimes or an apple is just fine (fruit is a great source of sugars, but it is also very healthy).
Problem is that in America and UK they manage to put additional sugar even in the pasta sauce… Everything is so sweet that it tastes bad for many foreigners (it tastes bad for me for instance)
Source: we have a similar background but mine is more theoretical (modelling, hpc, biophysics, theoretical biophysical chemistry and theoretical chemistry), I have a PhD as well and I used to work in academia (on both biological mechanisms and materials for renewable energy) before moving to AI in industry (different sectors). We are saying the same :D
Do basic groceries abuse sugar? And I’m not talking about the “organic” ones

Glucose (a sugar) is also literally the main fuel of human cells and the only one for brain cells…

Sorry I don’t understand what you mean. Could you please rephrase? Thanks
