Caffeine is a molecule of the alkaloid family, like cocaine. Powerful, it has interesting effects if consumed in moderation. Caffeine stimulates and increases alertness, delays the onset of fatigue and promotes endurance.
Coffee also plays on our brain by developing our memory and regulating our mood. It protects our liver because it limits the risk of cirrhosis. It helps our heart to function because it promotes blood circulation. And, coffee also helps reduce risks of type 2 diabetes and gout.
If the tolerance of coffee varies from person to person, too much caffeine can cause palpitations. It is recommended not to exceed the daily dose of 200 to 300 mg, that is to say up to 3 or 4 cups of 100 ml. Pregnant women should not drink more than one cup per day, as caffeine crossing the barrier of the placenta can have effects on the nervous system of the fetus.
Remember that an espresso has less caffeine than a filter coffee. Indeed, the more water is spent on the coffee, the more caffeine is extracted.
