Fasting has a positive effect on the brain

A group of scientists from the University of Swansea found out that ghrelin is known as the hunger hormone, which is released to the food consumption and increases appetite, stimulates neurogenesis process – the formation and integration of new brain cells. In addition, this hormone protects the brain cells from the negative effects of aging.

GrelinAccording to the results of previous studies, it has been established that ghrelin can improve the cognitive functions of animals. The experimental rodents, who were administered the hunger hormone, showed good results in the testing aimed at learning and memory.

It should also be noted that the number of neural connections – synapses – has increased in the brains of rodents.

As part of the new study, experts injected homons into the brain cells of rodents that were grown in a petri dish. The results of the studies showed that the hormone of hunger activates a gene that encodes the growth factor of fibroblasts – proteins that play an important role in the process of neurogenesis.
