Researchers warn the amygdala — the part of the brain which regulates fear — is also affected.
So a bad diet could mean some dangerous decisions.
But diets with extra omega-3 fatty acid DHA, found in fish such as salmon, could ward off problems. Rather than supplements, researchers advised improved diets.
Scientists at America’s Ohio State University Institute for Behavioural Medicine Research did tests on lab rats.
Dr. Ruth Barrientos called the results “alarming”, adding: “Consumption of a processed diet can produce significant and abrupt memory deficits.”
