Spilling the beans on caffeine consumption

Key takeaways:

  • Caffeine is a stimulant that occurs naturally in more than 60 plants.

  • Caffeine affects chemicals in your brain and stimulates your nervous system to reduce tiredness and keep you awake.

  • FDA guidelines say up to four 8 oz. cups of coffee are safe for most healthy adults to consume every day.


The pandemic ushered in many lifestyle changes as a large number of us began working remotely, sheltered in place or made other modifications to our daily routines. We kept a firm grip on our coffee cups throughout it all, according to research released recently from the National Coffee Association.

Restrictions may have slowed down business at the local coffee shop, but that didn’t stop us from getting our daily caffeine fix. Nearly 85% of coffee drinkers report they have at least one cup of coffee a day at home with most enjoying a second cup. Consumption is also rising as people turn to caffeine to help battle pandemic fatigue and burnout.

For many people, caffeine is an integral part of the day. It’s a quick pick-me-up in the morning or a way to boost energy during an afternoon slump. But what is it? And how is it affecting your health?

Our “What You Drink” series helps answer those questions. The first article in the series took a good look at the amount of liquid sugar hiding in your favorite beverages. This month we spill the beans about caffeine and its effect on your health.
