This is the first time an upper limit has been placed on safe coffee consumption and cardiovascular health. “Coffee is the most commonly consumed stimulant in the world — it wakes us up, boosts our energy and helps us focus — but people are always asking ‘How much caffeine is too much?’,” Prof Hypponen says. “Most people would agree that if you drink a lot of coffee, you might feel jittery, irritable or perhaps even nauseous — that’s because caffeine helps your body work faster and harder, but it is also likely to suggest that you may have reached your limit for the time being.
While the pros and cons of drinking coffee have been debated for decades, new research from the University of South Australia reveals that drinking six or more coffees a day can be detrimental to your health, increasing your risk of heart disease by up to 22 percent. From a report: In Australia, one in six people are affected by cardiovascular disease. It is a major cause of death with one person dying from the disease every 12 minutes. According to the World Health Organization, cardiovascular disease is the leading cause of death, yet one of the most preventable. Investigating the association of long-term coffee consumption and cardiovascular disease, UniSA researchers Dr Ang Zhou and Professor Elina Hypponen of the Australian Centre for Precision Health say their research confirms the point at which excess caffeine can cause high blood pressure, a precursor to heart disease.
