What you eat really does affect how you think.
A UCLA study on rats in 2012 found that a high-fructose diet over the long term slows the brain and alters it’s ability to learn, solve problems and remember information. Now, a new rodent study shows how fructose impairs the brain’s ability to heal after head trauma. Fructose is a simple sugar found in honey, fruits and vegetables. If you eat a variety of whole fruit and vegetables, you will find it difficult to ‘overdose’ on fructose.
The main source of fructose in our diets is from added sugars (e.g. refined table sugar, fruit juices, soft drinks, confectionary), not from the natural sugars in whole plants. Table sugar (sucrose) is equal parts fructose and glucose. High Fructose Corn Syrup (HCFS), also called glucose fructose syrup, is a mixture of glucose and fructose found in soft drinks and many processed foods.
Rat Study: High Fructose Diet Slows Brain Injury Recovery by Traci Pedersen
A diet high in processed fructose may impair the brain’s ability to heal after head trauma, according to a new rat study by neuroscientists at the University of California, Los Angeles (UCLA).
“Americans consume most of their fructose from processed foods sweetened with high-fructose corn syrup,” said Dr. Fernando Gomez-Pinilla, a professor of neurosurgery and integrative biology and physiology at UCLA’s David Geffen School of Medicine. “We found that processed fructose inflicts surprisingly harmful effects on the brain’s ability to repair itself after a head trauma.”
Although fructose occurs naturally in fruit, the inherent antioxidants, fiber, and other nutrients in the whole fruit prevent the same damage.
The findings add to the mounting evidence of the direct connection between nutrition and brain health.
