What Dose of Coffee Protects the Heart from Heart Attack
The article discusses safe caffeine doses: 400 mg per day is considered a safe limit. Caffeine concentration varies: espresso contains 75 mg, filter coffee up to 140 mg. Moderate consumption (2–4 cups) reduces the risk of heart disease. Energy drinks are dangerous due to the combination of caffeine and sugar. Individual sensitivity requires dose adjustment.
The article discusses safe caffeine doses and their impact on the cardiovascular system. According to current medical data, for most healthy people, 400 mg of caffeine per day is considered a safe limit. However, caffeine concentration varies greatly among different drinks: a standard espresso contains about 75 mg, while a cup of filter coffee or French press contains up to 140 mg. Therefore, relying only on the number of cups is a mistake. Caffeine is also found in tea, chocolate, soda, and energy drinks, which are especially dangerous due to the combination of large doses of stimulant with sugar, increasing the risk of tachycardia and arrhythmias. Moderate coffee consumption (2–4 cups per day, 140–300 mg) is associated with a reduced risk of coronary heart disease, heart failure, and stroke, thanks to antioxidants and polyphenols. Black coffee without sugar and milk provides the maximum benefit. The reaction to caffeine is individual: in case of anxiety, rapid heartbeat, or insomnia, the dose should be reduced, and if symptoms are systematic, consult a cardiologist.
