I have a question about decaf coffee. How much caffeine can this coffee contain? Is there a limit? Can it be that you get tachycardia even though you only drank decaffeinated coffee?
According to the regulation on coffee, coffee and chicory extracts, decaffeinated coffee may contain a maximum of 0.1 percent caffeine within the EU. Just like “non-alcoholic” beer, decaffeinated coffee can still contain a small amount of caffeine.
Here is a brief overview of the caffeine content of various foods and drinks:
| Drink / Food | Average caffeine content (mg) |
| 1 cup of decaffeinated coffee (150 ml) | 3 |
| 1 cup of coffee (150 ml) | 50-100 |
| 1 cup espresso (50ml) | 50-150 |
| 1 cup instant coffee (150 ml) | 15-90 |
| 1 cup of black tea (150 ml) | 20-60 |
| 1 cup cocoa (150 ml) | 2-8 |
| Milk chocolate (100 g) | about 20 |
| Dark chocolate (100 g) | about 75 |
| Cola (330 ml) | 32-60 |
| Energy Drinks (250ml) | about 80 |
Of course, there are many reasons for heart palpitations. We cannot judge whether the amount of caffeine in your decaffeinated coffee is the cause.
What is certain is that the tolerability of caffeine varies from person to person. If you are very sensitive to caffeine, you should also notice reactions after consuming other foods containing caffeine (see table).
