This is the full text in case anyone wants to analyze it.

Can it be early PUFA damage messing with sugar metabolism?
„In the present study, given that the main contrasting cognitive effects were present between the glucose-containing and glucose-free sweeteners, it is tempting to speculate that glucose is the mediator of the obtained effects. Of course, this deduction rests on the assumption that blood glucose is proportional to extracellular glucose [35]. The observation of poorer cognitive performances after ingestion of glucose- containing drinks contradicts some previous studies [13,14,36]. Pre- vious research has recognised that aging and individual differences in gluco-regulatory efficiency could contribute to inconsistent effects on the relation between glucose and cognitive effects [8,37]. The present study recruited participants from a relatively narrow and young age band with assumed similar gluco-regulatory control, which may par- tially explain the contrasting findings.“


Maybe the slower reaction times were a result of immediately lowered stress?
„In addition, the present study found that the contrasting effect due to glucose ingestion appeared to be more pronounced in the fasting group compared to the non-fasting group.“

First of all, that headline "Sugar is...." is completely misleading as it suggests sucrose to be the bad guy, but the worst result (or, lets say their interpretation of a bad performance) was seen in the glucose group. The whole study design is just wonderful -12 grams of sucrose...:eek::rolleyes:
They also don't provide any explanation for why they used twice the amount of glucose compared to sucrose. All they showed is that postprandial glycemia has some effect on reaction time. A breathtaking discovery.

"Across the four experimental sessions, each participant consumed sweetened drinks (250 mL) containing one type of the following sweeteners–glucose (26.0 g), sucrose (14.5 g), fructose (13.0 g), or sucralose (0.025 g). The energy content of these four drinks was 25, 14,12 and 0 cal. All solutions were flavoured by a non-caloric lemon"

I asked Dr. Peat about it. This was his answer:

"People under stress, such as fasting, have increased sympathetic nerve activity and increased alertness; certain measures of cognition are measuring relative alertness."

Nothing new.
There are paradigms established in a scientific field, and the whole field is arranged in a way that stabilizes said paradigm. Imagine you are a young upcoming phd student with different findings from mainstream. Do you publish them?
No, because the system will spit you out for doing that. You will be at conferences arguing with people with more credentials who have built careers on beliefs that you deem wrong. It‘s a defensive mechanism hardwired in the architecture of modern science.
Paradigm shifts are extremely rare for this reason, especially if they leave no room for integration of old paradigms by completely overriding them and therefore implicating that complete horseshit has been taught.
One example that comes to mind was einsteins relativity theory, that completely proved some well established corner points in physics wrong. The evidence was hard though, and provable through experiments.
In medicine, you can just fake everything basically.
The people publishing wrong stuff believe they are true, at least most of them. They completely lack the critical capacity to even comprehend the thought that established paradigms could be wrong.
They are professional idiots who function in a bubble based on hierarchy, not truth.
Try to discuss it with them and they will most likely not understand, or shut you off as you start making that point.

Thanks everyone for the insightful analysis. Most people would only read a headline.
