A Coffee “Cap”? 



A recent study says drinking six or more cups a day may negatively affect your heart health, BUT drinking too little may also do the same.


The Study

  • Researchers at the University of South Australia examined health data of nearly 350,000 adults ages 37 – 73 and focused on a caffeine-metabolizing gene.
  • RESULTS:  People who drank 6 or more daily cups of (caffeinated) coffee had a 22% increased risk of heart disease vs. those who drank 1 – 2 cups daily.

More or Less Java?

Compared to those who drank 1 – 2 cups of caffeinated coffee daily, researchers found:

  • Non-coffee drinkers had a 11% increased risk of heart disease
  • Decaf coffee drinkers had a 7% increased risk of heart disease

[1 cup = 8 fluid ounces]


“Most people would agree that if you drink a lot of coffee, you might feel jittery, irritable or perhaps even nauseous … but it is also likely to suggest that you may have reached your limit for the time being. We also know that risk of cardiovascular disease increases with high blood pressure, a known consequence of excess caffeine consumption.”

Also Worth Noting …

  • A study released in 2018 of nearly 500,000 British adults found that coffee drinkers were 10 to 15% less likely to die (compared to non-coffee drinkers) during a 10-year follow-up period.
  • A 2017 University of Colorado study found that coffee drinkers are 7% less likely to develop cardiovascular failure compared to non-coffee drinkers.

The average American drinks more than 1 cup each day, according to the most USDA recent information. A venti ice coffee from Starbucks is 24 ounces -- that's three cups.
