Green tea has been valued for centuries as a beneficial drink for human health. The results of scientific research reveal another peculiarity of this drink. According to scientists' observations, the substances in green tea can slow down the brain aging process and be an effective protection against Alzheimer's disease.
Experts say that the antioxidant substance called epigallocatechol gallate (EGCG) in green tea restores the energy balance of nerve cells. At the same time, it helps cleanse harmful protein residues that accumulate in cells. This process is very important for brain function, because with age and especially in Alzheimer's disease, the amount of guanosine triphosphate (GTP), which is an energy source in cells, decreases.
GTP deficiency disrupts waste removal systems in cells. As a result, various harmful proteins begin to accumulate. Among them, the most dangerous is the Alzheimer's-associated beta-amiloid protein.
Laboratory tests showed that EGCG in combination with nicotinamide (a type of vitamin B3) could restore GTP levels in aging nerve cells within just one day. This activated the process of cell self-purification, increased resistance, and reduced the effect of oxidative stress.
Other benefits of green tea
Green tea is invaluable not only for brain health, but also for the whole body. The strong antioxidants in its composition help prevent cardiovascular diseases. At the same time, it is noted that it normalizes metabolism and reduces the risk of certain types of cancer.
Interestingly, EGCG can penetrate the natural protective barrier between the blood and the brain. This barrier prevents many substances from entering the brain. But EGCG reaches the nervous system directly. Scientists believe that in the future, this aspect may open up new opportunities for the development of new medicines.
Thus, regular consumption of green tea is important not only for daily health, but also for maintaining a person's youth and brain function for a long time.
