Palpitations and restlessness
Anxiety and nervousness
Sleep disturbances
Long-term cardiovascular and bone effects
Certain groups are more sensitive to caffeine, including pregnant women, children, and people taking heart or anxiety medication.
The ideal daily dose of coffee
Dr. Wen reminds us that “up to 400 mg of caffeine per day – roughly equivalent to four cups of filtered coffee – is a safe intake for most adults.”
This corresponds approximately to:
4 cups of filter coffee, or
3 espressos, or
2 large American-style coffees
Beyond that, side effects such as tremors, irritability, or insomnia may appear.
Tips for enjoying coffee safely
Every morning, millions of people start their day with a steaming cup of coffee. Its comforting aroma and energizing effect have made it a universal ritual. But how many cups does it take for this pleasure to become harmful to your health?
Doctors are raising the alarm while reminding us that, when consumed in moderation, coffee can also be beneficial to our health.
Why coffee is good for your health
According to Dr. Leana Wen, emergency physician and professor at George Washington University, “the evidence is strong: moderate coffee consumption is associated with a reduced risk of developing certain chronic diseases.”
Numerous studies confirm that moderate coffee consumption can:
Reduce the risk of cardiovascular disease
Decrease the risk of type 2 diabetes
Protect against certain cancers and dementia
Coffee contains antioxidants and anti-inflammatory compounds that support the immune system and protect cells. Some components also help improve insulin utilization and stabilize blood sugar levels.
But beware of excess
Too much caffeine can have the opposite effect.
According to ANSES (the French Agency for Food, Environmental and Occupational Health & Safety), about 30% of adults and 11% of children in France consume more caffeine than recommended. This can cause:
Palpitations and restlessness
Anxiety and nervousness
Sleep disturbances
Long-term cardiovascular and bone effects
