Coffee and tea has become a favorite drink for many people around the world. But the beneficial effects of caffeine in coffee as a psychoactive drug that can preserve brain function began to be appreciated recently.
Recent research by international experts from the University of Lisbon and the University of Coimbra, Portugal, found that the caffeine in coffee and tea may protect us from cognitive decline seen in dementia (senility) and Alzheimer’s disease.
“The first epidemiological studies showed an inverse relationship between caffeine consumption with the incidence of Parkinson’s disease. Then some further epidemiological studies indicate that moderate amounts of caffeine consumption are also inversely related to cognitive decline associated with aging and the incidence of Alzheimer’s disease,” said Alexandre de Mendonca, of the Institute of Molecular Medicine and Faculty of Medicine, University of Lisbon, Portugal.
Besides bitter coffee, bitter tea can also fight dementia. Laboratory tests found that drinking a cup of black and green tea regularly can inhibit the activity of certain enzymes in the brain which are in Alzheimer’s, a form of generative dementia that affects 10 million people around the world.
Based on the Phytotherapy Research journal, Alzheimer’s is characterized by a decrease of acetylcholine. Bitter coffee and tea can inhibit the activity of the acetylcholinesterase enzyme (AChE), which breaks down chemicals, or neurotransmitters, and acetylcholine.
Besides that, coffee, black tea and green tea also inhibits the activity of the butyrylcholinesterase enzyme (Buche), which is found in protein deposits in the brains of Alzheimer’s.
“Although there is no cure for Alzheimer’s, coffee and tea has the potential to become another weapon that is used to treat this disease and slow its growth,” said Dr Ed Okello, researcher from the Medicinal Plant Research Centre at Newcastle University, England.
But remember you should only have just enough bitter coffee or tea every morning. Because excessive coffee drinking can increase stroke due to damage to blood vessel walls. In pregnant women, it can increase heart rate, attack the placenta, enter the blood circulation and can even cause death.
