My point is exactly this: glucose, fructose and sucrose are not unhealthy. Eating too much of them is the problem. Sugars 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 big source of sugars but it is also really good for health).

Problem is that in America and UK they manage to put additional sugar even in the pasta sauce... Everything is so sweet that is taste 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), I have a PhD as well and I used to work in academia as well before moving to AI in industry. We are saying the same :D
