A cup of strong freshly brewed coffee - what could be better? Just one more cup in the morning at work! And one more - a colleague from a neighboring department dropped by to chat. And then another one - well, I just can't wake up. And another cup for lunch - there is a lot of work, you need to mobilize all the resources ...
Coffee is a great natural stimulant. The natural alkaloid caffeine contained in it has an exciting effect on the human body, activates the production of serotonin and dopamine. These hormones are responsible for feelings of pleasure and stress relief, so coffee really helps to lift your mood and invigorate you. According to some reports, coffee is able to inhibit pathogenic microflora, reduce allergic reactions and even resist the appearance of neoplasms. But too much coffee can overstimulate the nervous system, overload the heart, and negatively affect the gastrointestinal tract.
So how many cups of coffee can you afford a day without harming your own body?
Cup to cup discord
First you need to decide on the volume of this very cup. Traditionally, it ranges from 70 to 100 ml. But, you see, there are practically no aesthetes using these miniature vessels now. Most of us drink coffee from ordinary tea cups, or even prefer glasses with a volume of 300-350 ml.
In the majority of studies on coffee, the term “cup” is understood as just the traditional coffee tableware, with a volume of about 100 ml.
Absolutely safe dose, contributing to the health of the arteries and slightly lowering the pressure (contrary to popular belief) - one cup a day.
Two cups, according to scientists, help prevent the onset of Alzheimer's disease.
Three cups may lower your risk of ovarian cancer and gallstone disease. But just with three cups a day, the risk zone begins - such an amount of caffeine is already quite capable of negatively affecting cardiac activity.

Four cups - prevention of tumors of the oral cavity, larynx and such an unpleasant disease as diabetes. But in this case, the risk of rheumatoid arthritis and inflammatory processes in the joints will increase.
Five cups may lower your risk of liver disease but increase your chances of developing osteoporosis.
Six cups is the limit. Overdose can result in irritable bowel syndrome, heart attacks, hypertensive crisis and even mental disorders.
Don't forget caffeine!
But in truth, just counting the cups isn't enough. For an accurate result, you also need to know the amount of caffeine in the drink. The average allowable dose for a healthy person is no more than 300 mg daily, so knowing how much of it is in a particular type of coffee, you can easily calculate the daily intake. For example, in espresso, the caffeine content is 80-135 mg, in cappuccino - 70-80 mg, in natural home-brewed coffee - 115-175 mg, in instant coffee - 65-100 mg. The amount of caffeine in the drink can be reduced by adding milk or lemon - coffee does not lose its taste, and its effect becomes less aggressive.
How to drink coffee correctly
To enjoy the taste of your favorite drink without consequences, it is worth remembering a few simple rules.
The optimal mode of use is three times a day in small cups of 100-120 ml. If you prefer a latte or cappuccino, you can increase the size of the cup.
Do not drink coffee on an empty stomach - it is harmful! It is best to do this immediately after eating or after a while. But do not forget that if you drink coffee after a meal, you should not accompany this event with sweets - this can overload the stomach.
The body's sensitivity to caffeine decreases with regular consumption of coffee, therefore, for true coffee lovers, the number of cups that is at the upper limit of the norm - 5-6 daily, is permissible.
It is advisable to drink the last cup of coffee 4-5 hours before bedtime, otherwise the stimulating effect of caffeine can ruin the entire night's rest.
Use only natural coffee beans or ground coffee. In soluble, there are no useful substances, and in cheap varieties, the composition, as a rule, is generally unknown. But instant coffee has a very harsh effect on the stomach, especially if you drink it on an empty stomach. It is believed that its regular intake can cause the development of gastritis. If you really want coffee, and only instant coffee is available, reduce the consumption rate to one cup a day.
