Nonetheless, there’s one other stealth aspect that might be placing them at excessive danger of future reminiscence points — and it’s possible in your kitchen pantry proper now.
A examine1 performed by researchers from the College of Southern California discovered that consuming a junk meals eating regimen throughout adolescence can result in long-term reminiscence impairment in maturity. Much more alarming is that the consequences might be irreversible.
Animal Research Exhibits Junk Meals Can Result in Poor Reminiscence
The featured animal examine,2 revealed within the journal Mind, Habits, and Immunity, sought to find out the consequences of feeding a junk meals eating regimen on adolescents’ brains. Whereas conducting the examine, the researchers thought of earlier findings {that a} poor eating regimen can result in Alzheimer’s illness.3
They discovered that the neurotransmitter acetylcholine performs a job, as it’s essential to reminiscence, in addition to different mind features like consideration and studying. Individuals who have been identified with Alzheimer’s illness are likely to have decrease ranges of this neurotransmitter of their mind.4
The researchers then questioned if adolescents who consumed the identical sort of processed meals eating regimen — loaded with unhealthy fat and refined sugar — may additionally expertise comparable results, particularly as their brains are nonetheless going by important growth.
To check their speculation, they fed one group of rats a “junk meals cafeteria-style eating regimen” consisting of potato chips, chocolate-covered peanut butter cups, and soda, and gave a management group a typical eating regimen.5 They then noticed the animals’ acetylcholine ranges and analyzed their mind responses by having them bear duties to check their reminiscence.
One check concerned permitting the themes to discover new objects in several eventualities. After a couple of minutes, they repeated the check however added a brand new object to the scene. The researchers noticed that the rats who ate the junk meals eating regimen have been unable to recall which objects that they had seen earlier than, in addition to their location. The management group, nonetheless, was extra acquainted with their environment.
In a StudyFinds article, Anna Hayes, a postdoctoral analysis fellow who’s a member of the analysis crew, defined:6
“Acetylcholine signaling is a mechanism to assist them encode and bear in mind these occasions, analogous to ‘episodic reminiscence’ in people that enables us to recollect occasions from our previous.
