I poked around on the internet for any mention of fructose + brain fog and didn't find anything, but did find sugar + brain fog linked. I can't recall if any of the many links provided in this thread talked about brain fog....

...Pimentel also contributes to the 'big picture' with his insight on serotonin. Serotonin, Pimentel points out, is present in ever-greater amounts in the digestive tracts of those with bacterial overgrowth of the small intestine. This is a very important detail, as the mysterious connection between the mind's function and the digestive tract is well-established.
Also, tracing back to studies on fructose malabsorption, it was found that subjects not absorbing fructose properly had low blood levels of tryptophan – the precursor to the formation of serotonin. This makes plain sense. Produce more serotonin, and blood levels of serotonin become depleted. Alter serotonin production and neurotransmitter levels can become skewed, as serotonin is thought of as the most dominant neurotransmitter, responsible for more than just moods but sleep. There is an association with virtually all psychological illness and abnormal serotonin levels – either too much or too little.
Those who don't absorb certain carbohydrates fully cause a hypersecretion of serotonin. This could initially lead to overbearing levels and later lead to depletion, causing the opposite imbalance. Thus, disorders of both high and low serotonin levels could be born in the digestive tract where serotonin is produced and absorbed.
"But my digestion is fine, I do not have Irritable Bowel Syndrome or anything like that" many of you might be saying. Not so fast. As the fructose malabsorption studies were able to show, as much as half of the people not absorbing fructose were completely asymptomatic from a digestive standpoint. Pimentel found that many hypoglycemics who weren't showing signs of digestive problems were failing breath tests miserably, revealing malabsorption issues. You may have bacterial overgrowth of the small intestine, you may not be absorbing certain types of slow and difficult-to-digest sugars, and you may have no idea. Yet, all the while, changes to your endocrine system and psychological well-being may be underway – fed by the continuing supply of sugars to these out-of-place bacteria...
