Fatty food ruins memory in 4 days: what scientists have discovered.

The impact of a harmful diet on memory

According to inkorr.com: A study conducted by the Medical School of the University of North Carolina showed that a Western diet rich in saturated fats can significantly impair memory even before the onset of excess weight. Scientists reported that excessive activity of CCK interneurons in the hippocampus deteriorates the formation and storage of memories, as stated in the journal Neuron.

Researchers noted that just four days of consuming fatty foods lead brain cells to dysfunction due to a lack of glucose. This quickly affects memory functions, even over a short period.

“We knew that nutrition and metabolism affect brain health, but we did not expect CCK interneurons of the hippocampus to suffer so quickly. We were most surprised that even a short-term deterioration in glucose supply immediately worsened memory,” said Professor Juan Song.

At the same time, restoring glucose levels in the brain allows normal cell function and memory recovery, indicating the possibility of correction through dietary changes or the use of intermittent fasting.

Healthy eating is the key to memory

Scientists intend to continue research to thoroughly investigate how CCK interneurons influence brain rhythms responsible for memory, as well as to check if diets that stabilize glucose levels can become a way to prevent dementia and Alzheimer's disease.

It is worth noting that dinner plays an important role in maintaining health. Experts recommend having the last meal a few hours before sleep, which helps improve sleep quality and metabolic processes.

Thus, the research showed that a harmful diet high in saturated fats can negatively affect memory even before the development of excess weight. The activity of certain cells in the brain begins to deteriorate just a few days after consuming unhealthy food. However, stabilizing glucose levels in the brain may contribute to memory recovery, opening new prospects for dietary correction and eating habits.
