These results suggest that high fructose intake, in the form of added sugar, independently associates with higher BP levels among US adults without a history of hypertension. -Increased fructose associates with elevated blood pressure
Note the researchers did not find a cause and effect relationship using a double blind study- they only are reporting that a relationship seems to exist.
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. -sciencedaily.com
The proposed mechanism? 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
MY COMMENT: Our diet is high in high fructose corn syrup- although not near the levels fed these rats. I found it interesting that researchers intend to follow up by seeing if exercise or fish oil offer any protection from memory impairment caused by fructose. I hope so.
The process is not so simple with fructose, he noted. “In order for fructose to be metabolized, the body has to create both fasted and fed conditions. The liver is really busy when you eat a lot of fructose.” sciencedaily.com
MY COMMENT: Confusion surrounds the effect of fructose on weight gain.
