Up to 5 cups of coffee per day may potentially lower heart disease risk, doctors say

Key Points:

• The American Heart Association (AHA) states that drinking up to five cups of coffee daily is safe for most adults and may be linked to a lower risk of stroke, type 2 diabetes, and heart failure.
• Recent clinical trials show that regular coffee consumption can reduce the risk of irregular heart rhythm recurrence by 39%, marking a shift from older guidelines that advised against stimulants for heart patients.
• Health benefits are associated with paper-filtered or instant coffee, while unfiltered coffee types like French press and espresso contain cafestol, which raises LDL cholesterol and may harm heart health.
• Highly concentrated synthetic caffeine products, such as energy drinks and caffeine pills, are linked to cardiovascular harm, including sudden blood pressure spikes and irregular heart rhythms, even in healthy adults.
• Individual caffeine tolerance varies due to genetics, and those with heart conditions or risk factors should consult a healthcare provider to determine a safe caffeine intake level.
