Scientists have named an effective diet for improving memory

A new study by the Institute of Psychiatry, Psychology and Neurobiology (Ioppn) of King's College London showed that intermittent fasting (IF) is an effective means of improving long-term memory and generating new hippocampal neurons in adult mice. Scientists hope that this approach can slow the progression of cognitive decline in the elderly.

The study showed that a calorie-restricted diet through intermittent fasting is an effective means of stimulating Klotho gene expression in mice.

Klotho, often called the “longevity gene,” was shown in this study to play a central role in the production of new neurons in the hippocampus, or neurogenesis.

The researchers divided female mice into three groups: a control group that received a standard diet, a calorie-restricted (CR) group, and an IF group. The latter two received 10% fewer calories than the control group.

Over three months, mice in the IF group showed improved long-term memory retention compared to the others. When the brains of these mice were studied, it was evident that the Klotho gene was activated and neurogenesis increased compared to mice in the CR group.
