We always hear that it’s bad to drink too much coffee. But how much is too much? What is the actual daily norm?
We shouldn’t measure coffee in cups. Some like it stronger while others want it to be significantly watered down. It’s better to measure the norm in caffeine quantity.
An adult is not recommended to drink more than 100-200 mg at once. And during the day the number of such portions should be no more than 2-3.
The optimal quantity of caffeine for the daily norm is no more than 300 mg.
Now to understand how much caffeine there is in one 100-ml cup let’s consider the main type of the drink:
- Brewed in cezve - the strongest one - 110-170 mg.
- Espresso – 80-130 mg.
- Cappuccino – 70-80 mg.
- Instant coffee – 60-100 mg.
With this list you can estimate how many cups a day you should drink. However, these indicators are approximate and depend on the type of coffee and how it was made.
For example, if you pour not cold but hot water on ground beans in a cezve, there will be less caffeine in the resulting drink.
You can also use milk to make the coffee milder.
Caffeine is a strong stimulator. In big doses it can be harmful for blood vessels and the heart. The result can be headaches and faster heartbeat. Combined with nicotine it can lead to a heart attack. Too much coffee can also cause depression and insomnia.
