Eating High Levels Of Fructose Impairs Memory In Rats

From Science Daily which really must be a "check it every day" website. It is that good.

Eating High Levels Of Fructose Impairs Memory In Rats:

"Researchers at Georgia State University have found that diets high in fructose — a type of sugar found in most processed foods and beverages — impaired the spatial memory of adult rats...."

and later

"Fructose, unlike another sugar, glucose, is processed almost solely by the liver, and produces an excessive amount of triglycerides — fat which get into the bloodstream. Triglycerides can interfere with insulin signaling in the brain, which plays a major role in brain cell survival and plasticity, or the ability for the brain to change based on new experiences.....Although humans do not eat fructose in levels as high as rats in the experiments, the consumption of foods sweetened with fructose — which includes both common table sugar, fruit juice concentrates, as well as the much-maligned high fructose corn syrup — has been increasing steadily."

This is based on a paper by Bartness, Mielke, Ross under the leadership of Parent.
