A diet high in processed fructose may sabotage the brains’ ability to heal after head trauma, UCLA neuroscientists report. There may be a link between nutrition and brain health, the finding offers implications for the 5.3 million Americans living with a traumatic brain injury, or TBI. According to the Centers for Disease Control and Prevention, an estimated 1.7 million people suffer a TBI each year, resulting in 52,000 annual deaths
“Americans consume most of their fructose from processed foods sweetened with high-fructose corn syrup,” said 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.”
Fructose also occurs naturally in fruit, which contains antioxidants, fiber and other nutrients that prevent the same damage.
The UCLA team found that fructose altered a wealth of biological processes in brains after trauma. The sweetener interfered with the ability of neurons to communicate with each other, rewire connections after injury, record memories, and produce enough energy to fuel basic functions.
“Our findings suggest that fructose disrupts plasticity — the creation of fresh pathways between brain cells that occurs when we learn or experience something new,” said Gomez-Pinilla, who is a member of the UCLA Brain Injury Research Center. “That’s a huge obstacle for anyone to overcome — but especially for a TBI patient, who is often struggling to relearn daily routines and how to care for himself or herself.”
Earlier research has revealed how fructose harms the body through its role in contributing to cancer, diabetes, obesity and fatty liver. Gomez-Pinilla’s study is the latest in a UCLA body of work uncovering the effects of fructose on brain function. His team previously was the first to identify the negative impact fructose has on learning and memory.
“Our take-home message can be boiled down to this: reduce fructose in your diet if you want to protect your brain,” Gomez-Pinilla stressed.
Sources of fructose in the western diet include honey, cane sugar (sucrose) and high-fructose corn syrup, an inexpensive liquid sweetener. Made from cornstarch, the liquid syrup is widely added as a sweetener and preservative to processed foods, including soft drinks, condiments, applesauce and baby food.
Although the article specifically addresses high-fructose corn syrup as it relates to recovery from brain injury, it seems to me the same issues would be a concern regardless of whether or not a person an adversity or an adversity different than brain injury. If high-fructose corn syrup adversely affects the communication of neurons, it must be true that it adversely affects anyone with a brain.
