Today we are talking about the favorite drink of the Lviv Regional Center for Disease Control and Prevention of the Ministry of Health of Ukraine. According to statistics, 2.5 billion cups of coffee are drunk in the world every day. The history of coffee as a drink goes back thousands of years. Coffee contains many useful substances: potassium, magnesium, calcium, phosphorus, vitamins, organic acids and caffeine. Everyone knows its invigorating properties. It is explained by the fact that caffeine is a psychostimulant. When we drink coffee, caffeine enters the brain, where it blocks the neurotransmitter adenosine.
Adenosine is involved in energy transmission, suppresses vigor and stimulates sleep. The concentration of adenosine in the body increases with every hour without sleep, causing drowsiness. When adenosine is blocked, the concentration of other neurotransmitters such as norepinephrine and dopamine increases. This gives a tonic effect.
Many studies confirm that coffee improves memory, mood, reaction speed, attention and cognitive functions. So coffee really invigorates and makes us smarter. When caffeine stimulates the nervous system, it sends signals to other parts of the body. Fat cells receive a signal to break down fat deposits.
In addition, caffeine increases the level of adrenaline in the blood, which prepares the body for intense physical activity. Caffeine increases the production of dopamine, a neurotransmitter responsible for movement, memory and thinking. Dopamine is also associated with a sense of pleasure. Therefore, coffee helps fight depression. Also, there are studies that confirm that regular coffee consumption reduces the risk of Alzheimer's disease and type 2 diabetes.
But! Do not overdo it! It is recommended that an adult consume no more than 400 mg of caffeine per day. A medium-strength coffee without milk contains approximately 100 mg of caffeine. Therefore, the daily norm is considered to be 3-5 cups of the drink, depending on the strength. Instant and unroasted coffee are considered less strong.
