How much coffee is too much for the heart?

17 May 2019

For many people, coffee is the magical brew that kickstarts the day, a much-needed pick-me-up in the afternoon, and sometimes even a well-appreciated digestive after dinner. However, how much coffee is too much? A large new study claims to hold the answer.

Many recent studies have suggested that drinking coffee can bring a number of benefits in addition to enhancing focus and productivity. In fact, researchers have argued that coffee can help maintain brain health, help increase a person's lifespan, and even slow down prostate cancer.

However, as with any food or beverage — even the most nutritious and healthful ones — there is a limit to how much coffee we can consume.

Not only can drinking too much coffee create ill effects in the short-term — some of the symptoms of overcaffeination are headaches, dizziness, and nausea — but consistently having too much of this drink could increase a person's risk of developing cardiovascular disease.

How much is "too much" for the heart? This is the question that scientists at the University of South Australia in Adelaide aimed to answer in their new study, the findings of which now appear in The American Journal of Clinical Nutrition.
