The mystical ingredient found in coffee protects against the development of Alzheimer's disease, according to scientists who conduct research in mice.
It was found that caffeinated coffee reduces the risk of disease by raising key protein levels, but caffeine alone does not have such an effect, researchers said, so we need to find this unknown as long as an ingredient.
The secret ingredient must react with caffeine to raise levels of a protein known as GCSF (granulocyte colony stimulating factor) that is believed to inhibit development diseases and improves memory in rodents suffering from Alzheimer's disease. In patients with this disease, GCSF levels are significantly reduced.
The relationship between an unknown ingredient and caffeine would explain why coffee protects against Alzheimer's disease, while other drinks containing caffeine do not.
“We are not yet clear why this is happening. There are mutually reinforcing effects of caffeine and some mystical coffee ingredient that increases GCSF levels in the blood,” says study author Chuanhai Cao, a neuroscientist from University of South Florida.
Human studies have shown that drinking caffeinated coffee daily in middle age and old age reduces the risk of developing Alzheimer's disease. Studies in mice have shown that caffeine is probably the ingredient that protects against disease because it prevents the production of the abnormal beta amyloid protein that is believed to cause disease.
However, increasing GCSF levels is very important because this protein helps improve memory.
Researchers have previously said that 4-5 cups of coffee a day are necessary to combat brain pathology and memory impairment in sick mice. Decaffeinated coffee is ineffective in this case.
“We cannot say that moderate consumption of coffee will fully protect a person from Alzheimer's disease. However, this significantly reduces the risk, “Kao said. Regular exercise and intellectual exercise can help reduce the risk of developing dementia.
