As explained by Medline Plus, the website of the United States National Library of Medicine, a liter of coffee, which is equivalent to four 8-ounce cups, prepared per day, is considered a moderate amount of caffeine for most people. If more than 1200 mg is consumed in a short time, symptoms such as seizures may occur.
It should be noted that it is important to verify with a doctor the amount of daily coffee that can be consumed, since each person is different, especially those who have health problems such as hypertension, etc.
Drinking coffee every day can bring health benefits. According to Donald Hensrud, MD, an expert at Mayo Clinic, a nonprofit organization dedicated to clinical practice, education and research, coffee may offer some protection once morest type 2 diabetes, liver disease, Parkinson’s disease, heart attack, and stroke.
The New York Times highlights that in various studies that have been carried out worldwide, the daily consumption of four cups of coffee has been related to a decrease in mortality rates.
“In a study of more than 200,000 participants followed for 30 years, people who drank three to five cups of coffee a day, with or without caffeine, were 15 percent less likely to die prematurely, for any cause, above the people who avoided coffee. Perhaps most dramatic was a 50 percent reduction in suicide risk among men and women who were moderate coffee drinkers, perhaps because they stimulated the production of brain chemicals that have antidepressant effects. communication.
Another benefit of coffee is that “because it is rich in caffeine, a compound that stimulates the central nervous system, coffee helps improve memory and alertness, In addition to increasing the ability to concentrate, it decreases sleep”, explains the specialized health portal Your Health.
Caffeine
Caffeine is not only present in coffee, it can be found naturally in tea leaves, cola nuts and cocoa beans.
Medline Plus mentions the different benefits of caffeine in the human body:
- It stimulates the central nervous system, which can make you feel more awake and give you a boost of energy.
- It is a diuretic, which means that it helps the body get rid of extra water and salt by urinating more.
- It increases the release of acid in the stomach, which sometimes leads to an upset stomach or heartburn.
- It can interfere with the absorption of calcium in the body.
- Increases blood pressure.
The consumption of this substance to perform physical activity also has effects on the body. The National Institutes of Health of the United States (NIH, for its acronym in English) point out some of the possible effects of coffee on sports activity:
- “It improves alertness and concentration, and decreases reaction time.
- Reduces fatigue and improves tolerance to effort.
- It enhances the effects of catecholamines at the cardiovascular level.
- Strength: power muscle contraction by increasing of calcium transport.
- It is diuretic (short-term: 2–3 h)”.
Along the same lines, NIH experts point out that coffee consumption related to physical activity is associated with disease prevention. “We can find a possible benefit in helping to control body weight, since at the peripheral level it has an inhibitory effect on phosphodiesterase and as a consequence increases cyclic adenosine monophosphate (cAMP), which translates into greater lipolysis or mobilization of fat from adipose tissue.
