Coffee is one of the most widely consumed beverages in the world. But what about its effects on health? And should we limit our consumption?
Is there a daily limit?
To answer this question, let’s look at caffeine. A daily intake of up to 400 mg of caffeine is safe for healthy adults (excluding pregnant women, for whom the maximum is 300 mg).
A cup of filter coffee contains between 80 and 180 mg of caffeine. A consumption of 3-5 cups of 250 ml per day is therefore considered adequate and without risk. Nevertheless, it’s important not to forget your other sources of caffeine, such as energy drinks, tea, cola, chocolate, guarana, yerba mate and sports supplements (like pre-workout or certain electrolytes) in your calculation.

What are the effects of coffee?
Caffeine is known to have several positive effects:
- Alleviating the effects of sleep deprivation
- Increased alertness
- Improved reaction time
- Improved sports performance
Caffeine intake can also cause negative effects such as insomnia, irritability, headaches and nervousness. These effects appear mainly with excessive caffeine consumption but can also occur with a single coffee for those with a low tolerance to caffeine.
As for long-term effects, excessive caffeine consumption (over 400 mg a day) has been associated with cardiovascular health problems. However, this association remains uncertain for coffee consumption per se. One hypothesis put forward to explain this is that the effect of certain other components of coffee, such as antioxidants, would counterbalance the negative effects of caffeine.
It is therefore possible to conclude that consumption of 3 to 5 cups of coffee a day is safe, but that the effects of higher consumption are uncertain and potentially harmful.
5 tips that can help you reduce your coffee consumption
If you feel that your coffee consumption is too high after reading this, discover these 5 tips that can help you reduce your consumption:
1. Gradually reduce your caffeine intake
A sudden reduction in caffeine intake can cause withdrawal symptoms, such as headaches or fatigue. It is best to reduce your intake gradually, for example by cutting out ½ to 1 cup of coffee a week.
2. Replace with decaffeinated coffee
If you want to reduce your caffeine intake without saying goodbye to its delectable taste, you can replace your regular coffee with a decaffeinated one. That way, you get all the pleasure, without the caffeine!
3. Replace with other beverages such as tea or herbal tea
If it’s the comforting effect you’re looking for in coffee, why not replace it with tea (which contains less caffeine) or herbal tea (which doesn’t)?
4. Gradually reduce add-ins
So far, we’ve talked about black coffee, but what if it’s not what you prefer?
If you add sugar (white sugar, brown sugar, maple syrup, honey, agave syrup, sweet creamer, etc.) or fat (cream, whipped cream, creamer, etc.) to your beverage, you are reducing its nutritional properties. If this is your case, you can gradually reduce the amount of sugar you add and use milk or an unsweetened vegetable drink to lighten your coffee. You can also discover tasty recipes to try out at home:
5. Get enough sleep
If you’re among those who drink coffee to compensate for a lack of sleep, tackling the problem at source will be the most effective way of reducing your consumption. Here are a few tips to help you achieve this.
