Coffee: Is It Good Or Bad For You?

Every morning I wake up and mumble one single word: “Coffee?” It’s my sole addiction, in that my day simply doesn’t start without it.

Is that cup of coffee good for you?

Whether or not it’s “good” for me, coffee has some positive results. That is, it gets me up and out of bed in the morning. More than one cup, however, and that’s when the trouble starts.

A study recently released by the Mayo Clinic states that young people should avoid excessive coffee consumption because they found a 21% increase in mortality rates. Yikes!


A Google search for “Is coffee bad for you?” brings up 135,000 results and “Is coffee good for you?” brings up 309,000 results. It won’t surprise you to know that the articles have conflicting results.

This article in Popular Science lists 7 reasons why coffee is good for you, but this one lists 10 reasons why coffee is bad for you.
One finding in particular stood out to me, though. That is, a connection between coffee and blood sugar. I have hypoglycemia, and when I have that second cup of coffee in the morning (especially without eating something substantial to go along with it), I tend to get rather dizzy and confused.

At first, I thought I was imagining this, but it turns out that feeling is substantiated. A few individual studies show an effect on blood sugar levels and another study done by the American Chemical Society showed that green coffee extract produced “a significant reduction in blood sugar”. This could be good for people with diabetes, but not so good for someone like me who already suffers from low blood sugar.

So, is coffee good or bad for you? With so many conflicting conclusions, maybe a starting point is to ask yourself: “How does it make me feel?”

For example:
– Does more than one cup of coffee make you feel more alert or just jittery? What about just a single cup?

– If you have diabetes or hypoglycemia, have you noticed any effect on your blood sugar?

– Are you feeling dehydrated? Are you making sure to drink more water than coffee?

– Do you have trouble sleeping at night? If so, it could certainly be related to too much coffee.

Whether coffee is ultimately good or bad for you, only you know how coffee makes you feel.
