Is Coffee Healthy or Is It Killing You? The Results of My 31 Day Coffee Fast

Being raised with Irish grandparents and cousins, a cup of tea was the answer to every question. The kettle was ever on the boil as there was always someone having a cup of tea. By the time I was a young adult, I was drinking at least 20 cups of tea a day. I was hooked on the buzz that it gave me. To break my tea addiction, I switched to coffee, which at the time tasted disgusting to me. But, like those first few cigarettes, you soon find yourself liking your drug of choice.

Once I acquired a taste for it, I had replaced my tea habit with coffee. I began working fulltime in Manhattan where everyone drank coffee all day. And, those workdays were at least 12 hours long. I easily drank 2-3 pots of coffee during the course of a day. Yeah, you read that right. I was this close to a caffeine IV drip.

It didn’t seem unusual to be a coffee addict. Everyone in NYC moved at light speed, and you always needed to be sharp. Coffee helps with all of that. I found though that I couldn’t drink it past 5pm because it would make sleep almost impossible. I cut down my coffee habit quite a bit since those days. But, I was still drinking about 2-3 mega-sized mugs throughout the morning.

On July 1st of this year, I went to a meditation retreat that only served herbal tea. We were advised to wean ourselves off the bean before attending. I didn’t get a chance to do that so I quit cold turkey. Because I was meditating and doing yoga every day, it was all good. I didn’t get headaches or even miss the coffee and I was getting a LOT of rest. When I returned home, I decided to keep up with the abstinence to see how long I could go. As it turns out, I made it all through the month. But, on July 31st, I looked back on the month and after much deliberation, I decided my life was better with coffee.

I had thought eliminating caffeine would reduce my anxiety. Turns out I felt even more anxious because I was sluggish and lethargic. I thought that I would sleep better without coffee. Turns out, I was waking before my alarm and getting even less sleep than usual. And, I was so tired in the morning. I also noticed that I was feeling down in the middle of July for no apparent reason. Being in the healthcare field, I wanted to find out whether or not coffee consumption was better or worse for me. There are data to support both sides. So, let’s see what the experts say.

Turns out that coffee has some nutritional value. It has vitamins & minerals that become somewhat substantial if you drink several cups a day. Coffee is also a powerful antioxidant. And, as a stimulant it boosts your metabolism. Not a bad thing. There are also mental health benefits – your mind is sharper. Who wouldn’t want that?

“Caffeine is the single most widely consumed psychoactive substance in the world,” says Warrior Coffee. Warrior Coffee sells their own proprietary coffee which I have not tried so I am not endorsing here. But, they’ve done their research on the benefits and risks of coffee consumption. So, I’m including their list and I’ve added some of the other sources’ findings in one easy to read chart. My references are embedded. While I‘m at it, let’s hear from the coffee critics. What do they have to say? Are their conclusions bad enough to outweigh the benefits of coffee? Let’s do this.

Well, that was enlightening. I had no idea there were so many healthy benefits to drinking coffee. I guess that’s why it’s been such a popular beverage for centuries.

Bottom line. Use common sense when using caffeinated products. If you are finding you can’t fall asleep at night, don’t drink coffee after noon and see if that helps. If you find that after a few cups of coffee, you feel anxious, try cutting back and observe the difference. Find your sweet spot. And, finally, consult with your doctor about whether your health is at risk by drinking coffee.

Everyone is different. You may find your morning beverage of choice is black or green tea. Both of these teas have health benefits and have been used for thousands of years. Learn to listen to your body.

Have you tried and failed to give up coffee? Or have you succeeded in giving up your morning jolt? I’d love to hear your experiences with caffeine, good or bad. Please comment below.

Thanks for that pros and cons comparison! It’s an easy quick reference to look up when talking to my friends about the benefits and risks of coffee drinking. I’m active coffee drinker, at about 3 cups per day on average. I don’t know how I’d get by without it. Course, many say the addiction to coffee is what makes it bad…. Yeah. I guess in a sense. But, supporting the health benefits like lower risk of alzheimers, type 2 diabetes, regulating blood sugar and other things like that… yeah. As long as you’re smart, you can live a pretty good life with the good ol’ bean machine 🙂


I find that a strong black coffee helps me with intermittent fasting. Typically I skip breakfast, doing 16:8. Coffee helps with any hunger pangs.


In my research, most of the pros posted here are accurate if you drink freshly roasted coffee. Since roasted coffee bean’s shelf life is somewhere around 2 weeks (at most) some of the commercialized coffee chain don’t give us coffee pro effect. Correct me if my research is wrong, I’m a coffee lover and I would like to get the correct info.


How long does vacuum packing (off the shelf at stores, obviously) preserve the freshness? I drink the excellent Café Du Monde (both with and without chicory) and go through the 13 and 15 ounce cans in less than one week.
Thanks for your research.


I’ve been a lifelong coffee drinker. But recently I’ve been cutting back on the habit.

Part of the reason is I’m a hyperactive hard-gainer, meaning I could stand to gain a few pounds (not lose them). The other part is I think the key is moderation. Well, what is moderation? One, two, three, five, ten cups? A day, a week?

My version of moderation is one cup two to three times a week. If I start drinking more, I feel jittery, wired, and frankly unwell. I drink my coffee slowly.

Something I’ve never seen in research, but have always wondered, is this: I’ve heard it said our heart is made to beat a certain number of times – and that’s it. Increased fitness reduces heart rate, and thus heart beats, over the long term, which is why it is recommended. Coffee causes heart rate to increase. Is that not then shortening your lifespan? I question the validity of claims that it lengthens lifespan.

In short – very few things, if any, are truly bad when used in the proper way, correct? Determining the proper way is often easier said than done, but I personally approach it like this – if you feel like you can’t stop consuming it, then it is probably an issue.

But!!!!! Coffee has sodium in it and can be bad. I drink more than 300 ounces of coffee a day and have had to cut back because if the swelling of ankles due to too much intake of sodium.

I am a coffee & tea lover. Hot tea in winter teabags from middle eastern grocery. Quality. Coffee according to my taste that day. Prefer Neighborhood (from LA) ground in a pour over storing leftovers in frig. If I am in a hurry have a barista with good grinder & water tank for fresh grind. Again, quality beans make large difference & expensive does not mean quality.

The coffee benefits include protecting against type 2 diabetes, Parkinson’s disease, liver disease, liver cancer, and promoting a healthy heart.
Coffee is one of the world’s most mainstream beverages. On account of its large amounts of cancer prevention agents and valuable supplements, it is by all accounts very sound.
