A team of scientists from the University of Southern California in Los Angeles (USA) found that a large number of fatty and sweet foods in a person’s diet permanently impairs the ability to remember information. Thus, mice fed junk food at a young age began to experience memory problems. Moreover, these problems did not disappear with age. The study results were published in the journal Brain, Behavior and Immunity.
People with Alzheimer’s disease have low levels of the neurotransmitter acetylcholine in their brains. Experts have revealed how the amount of this substance in mice is affected by the consumption of sweet and fatty foods.
It turns out that rodents that grew up on junk food cannot remember objects they saw a few days ago. However, such problems did not occur in the rats in the control group. This is because acetylcholine signals help animals encode and remember information. These signals are not present in people who eat fast food at a young age.
Scientists also found that memory problems persisted even after switching to healthy foods. In this case, medical intervention may help.
