Coffee: 10 Shocking Reasons Why It’s Soooo Bad For You

I know some of you coffee worshipers aren’t going to like this article so much, but I’d just like to share my own experiences with the beautifully delicious but devilish creature that is coffee. It’s been a few months now since I finally kicked the habit and so I can totally resonate with those in the process of giving up because coffee is definitely a big bad drug!

I was the biggest coffee addict who ever lived! In my opinion, many people are truly addicted to coffee, causing them to feel extreme ups and downs in their nervous systems. This is the very reason I decided to quit as I was constantly getting those ups and downs, highs and lows which were honestly just exhausting!

Originating from Ireland there wasn’t so much of a coffee culture growing up and I have to say it was upon arriving in Sydney 6 ½ years ago when my dirty habit began and quickly flourished. Working in the corporate world at that time, there was (and still is!) coffee freely available everywhere you look and at every corner throughout the city.

People are coffee crazy! Coffee for breakfast, coffee for mid-morning break, coffee at lunch and finally afternoon pick me up coffee! I soon fell into this seductive habit and it wasn’t long until I couldn’t go without my morning coffee ritual and sometimes even a coffee in the afternoon to pick me up.

I literally tried so many times to quit coffee during this time; I tried to tell myself that I didn’t have an addiction and that I deserved these 1-2 coffees a day. I worked hard goddamat and I deserved a little reward (so I kept telling myself anyway!).

At times I’d quit coffee for up to a month but then eventually I’d come crawling back to it (normally triggered and lured back in by the sight and smell of it whilst catching up with friends). I tried so many times throughout those years to quit but could never make it fully stick!

It wasn’t until I was introduced to Sally Fallon Morell of the Weston.A.Price.Foundation and many others during my studies as a health coach at IIN that it really began to sink in how unbelievably wicked coffee really was.

So finally I decided I had to end my relationship with coffee completely and entirely, once and for all as it was clear it no longer served me. It was making me feel burnt out and exhausting my poor adrenals. Did you know that caffeine jolts the adrenal glands and can eventually lead to adrenal exhaustion? Yes, just one of the many “gifts” from coffee….

The Dark Side of Coffee Dependence

The well-known but poorly understood hormone adrenaline is produced by the adrenal glands from the amino acids phenylalanine and tyrosine. When you eat protein-rich foods that contain amino acids, your body naturally produces these hormones and other brain chemicals that make you feel active and motivated and ready to get to work. If you take the coffee shortcut to get your quick fix of hormones you’re exhausting your adrenals — the very organs you need to help you produce more hormones.

Like sugar, caffeine is a stimulant of the neurotransmitter serotonin; this is a hormone in our brain that controls our sleep, mood and appetite. When our body depends too heavily on materials such as caffeine to control serotonin production and energy, this impacts on the body’s natural ability to regulate healthy serotonin production. This is the reason for the highs and lows you may experience after a coffee; I know I certainly got these dips throughout the day.

On top of this, it tricks you in to thinking that you’re not hungry and hunger is our body’s way of telling us that we need nutrients. My point is if we take a drug (caffeine) that interferes with our hunger mechanism, we are depriving our body of the stimulus it needs to function naturally. We continue to top up on coffee, further delaying and depriving our body of nutrients and the cycle continues in one big vicious circle.

Thinking of Quitting?

Something I hear a lot from clients is how tired they constantly feel and the lack of energy they have. They never stop to think that caffeine could be their problem. It often is.

So those of you who think you’re not a breakfast person and survive on a coffee each morning, try experimenting and abstaining from your beloved morning coffee for even a short period of time (say 1 week) and see if you notice any positive will!

You can either start by cutting out your afternoon hit or just go crazy and cut it completely out like I have done. It’s actually not as hard as you think and there are so many replacement options like; green tea, roasted dandelion tea, chai tea, rooibos tea, lemongrass tea etc. to name a few. So many more delicious herbal teas out there to experiment with, T2 is one of my favourite stores and a great place to start!

Or why not try my Online 7 Day Online Cleanse which will help kick-start you in the right direction. You can take a look at it HERE.


A study at Duke University showed that caffeine in your morning coffee is confirmed to put you in a state of sustained stress, affecting both blood pressure and heart rate all through the day.


10 reasons why you might want to kick that coffee habit!

1. Cardiovascular Problems

Yes caffeine does indeed increase heart rate, elevates blood pressure and can contribute to the development of heart disease.

2. Stress

Caffeine stimulates the flow of stress hormones, which can produce increased levels of anxiety, irritability, muscular tension and pain, indigestion, insomnia and decreased immunity.  Increased levels of stress can keep you from creating healthy reactions to normal daily stress.

3. Emotional Troubles

Anxiety and irritability are guaranteed mood disturbances associated with caffeine consumption, but equally important are depression and attention disorders.

4. Blood Sugar Swings

Diabetics and hypoglycemics should avoid caffeine. Caffeine stimulates a temporary rush in blood sugar followed by an overproduction of insulin, which causes a blood sugar crash within hours. This roller coaster causes weight gain since insulin’s message to the body is to store excess sugar as fat.

5. Gastrointestinal Problems

Many people experience a burning sensation in their stomach after drinking coffee because coffee increases the secretion of hydrochloric acid, which leads to an increased risk for ulcers. Coffee, including decaf, reduces pressure on the valve between the esophagus and the stomach so that the highly acidic contents of the stomach pass up to the esophagus, which can lead to heartburn and gastro-esophageal reflux disease.

6. Nutritional Deficiencies

Caffeine inhibits the absorption of some nutrients and causes the urinary excretion of calcium, magnesium, potassium, iron, and trace minerals. So you could be eating very healthy but then washing I down with a coffee only to be losing some of those nutrients from food.

7. Male Health Problems

Milton Krisiloff, MD, has found that in the majority of cases, men can significantly reduce their risk for urinary and prostate problems by making dietary changes, which include eliminating coffee and caffeine.

8. Female Health Problems

Fibrocystic breast disease, PMS, osteoporosis, infertility problems, miscarriage, low birth weight and menopausal problems such as hot flashes are all aggravated by caffeine consumption. Women on birth control pills are particularly at risk since they tend to have a decreased ability to detoxify caffeine.

9. Aging

Many people find that in their 40s, they can no longer tolerate the same level of caffeine consumption they could in their 20s and 30s. Production of DHEA, melatonin and other vital hormones decline with age, but caffeine speeds up that process. Caffeine dehydrates the body and contributes to aging of the skin and kidneys. It has been shown to inhibit DNA repair and slow the ability of the liver to detoxify foreign toxins.

10. Adrenal Exhaustion

Caffeine consumption can lead to eventual adrenal exhaustion, which can leave you vulnerable to a variety of health disorders related to inflammation and fatigue. This was enough to make me quit along with those female hormone health problems – no thank you!

  1. Coffee is, essentially, weak, liquid cocaine. During periods when I have given it up I felt wonderful. So relaxed and able to sleep deeply. I am resolved to give it up for good. I believe this is possible now since I have had no alcohol for a year and a half. There is nothing to send you scurrying back to the Joe like a hangover.

  2. Yes you are completely right, I can relate to dealing with all of the above in the past. If I can do it, you can too. Best of luck! It’s very possible!

  3. I’m gonna switch to tea :)

    • Good choice -)

      • So tea and it´s caffeine is ok? I drink a ton of green tea throughout the day and lemon grass tea before I go to bed…in between liters of water. I love my red wine, but I am cutting it out for 3 months.
        I have heard that drinking a warm cup of lemon water in the morning is a good start to the day.

  4. Coffee comes from a plant that many of its users have never seen, touched or dealt with. It’s a packaged & taxed addiction. It attracts users with its unique mouth watering aroma. Much like marajuanas-thb, cigs-nicotine, the caffeine and hundreds of other chemicals in coffee keeps its users hooked. Without ones first cup of the day, it’s worse than a bad break up, as though tears have fallen for hours-the incapacitating headache, depression and nausea set in. Luckily in the end it’s just a plant, and once relieved from its addicting compounds, one’s natural state can be restored. It’s all or nothing for most of us, but how romantic an occasional love affair with a glorious cup of rich aromatic coffee would be. Actually, it makes my stomach hurt thinking of it. I’ve tithered down to from full time to 1/2 cup to 1/4 cup each day this week. I plan on being off next week. I’ve bought a bag of lemons to detox. This way I’ll still have a hot drink in the A.M. I’m a tea drinker too, and this isn’t my first breakup. Good luck to the old timers and those who’ve put it down-kudos to you!

    • Thanks for your informations. I do my best to quit coffee.

  5. What if you drink decaf? I’m seriously curious. I worked at Starbucks for close to a decade & saw the addicts first-hand, plsu was one myself for MANY YEARS. I now drink 90% decaf. And try for Swiss Water Processed (instead of the ones using dichloromethane or ethyl acetate) as much as my budget will allow.

  6. First off, you can’t trust any formal studies about this because they are usually biased. But if you think about this logically, it makes sense that caffeine is bad. Why do you think plants have caffeine in them at all? Here’s why: ALL plants have small amounts of toxins in them as a defense mechanism so that animals don’t eat too much of them (i.e. so the plant doesn’t die). These toxins vary from plant to plant. This also forces animals to get a variety of greens in their diet (i.e. the toxin makes them want to move off that plant and try a different one). It’s a win-win situation, mother nature is brilliant. However, when you make coffee, you are concentrating that caffeine toxin into an amount that is a lot for the body to take. Everyone will be different in how much of that toxin they can tolerate, but make no mistake, it IS a toxin!!!

  7. while coffee is the mildest of all drugs and the safest one and the least evil….i agree that it its no good and everyone should give it up…its all true it messes up your digestive system your hunger levels so you end up overeating in the evening it gives you depression when it wears off…and makes you very tired if you stop taking it…you cant sleep properly when drinking it…its a drug the same as any other just the safest one cos you cant get too high on it and the easiest one to quit….i mean to heroin addicts this article might seem rediclous ..but once you’ve given up opiates you realise that coffee is kinda similar cos its also a drug…i slept for 4 days when is topped drinking coffee) really i woke up had breakfast showered and went right back to sleep and slept all day long and all nite long…while its certainly better than insomnia on opiates withdrawl and restless legs syndrome and suicidal depression you get on opiate withdrawl….it still is pretty weird to feel so tired you cant stay awake for 4 days….all drugs are evil even coffee

  8. I’ve decided to quit drinking coffee, but i still drink a cup sometimes when i think didn’t get enough sleep..
    i had to stay awake because of my job.but every time i do, i get a stomachache after a few hours.

  9. Since I am the alkaline diet advocate, I had to quit coffee. And this was the best health decision I have ever made in my entire life. I now feel energetic, focused and vibrant. I would recommend quitting or at least reducing coffee for better health and wellbeing. Some people say: go for coffee with milk! Another mistake…milk makes it even a more harmful combination. I am not a scientist nor a doctor but this very statement is something I heard from a few medical and naturopathic doctors who care and I also agree with it. When quitting coffee, I would gradually make it weaker and weaker and I drank it with almond milk( it is alkaline). This is how I prevented headaches and moodiness. Some people go ‘cold turkey’. Coffe is such a stupid drug…like all drugs, lol!

  10. Are you stupid? Get your information from a reputable source not a wiki page.

    • I think that you should put down that cup of coffee and stop calling people names.

  11. Some of the points in this article are either untrue by further studies or exaggerated. It’s true that blood pressure can increase, but the effects of blood pressure are virtually gone after a few weeks. With that said, if someone has out of control blood pressure, they should probably avoid coffee. Psychological problems are also possible, but these reasons are a bit exaggerated. If you go to Starbucks and order a large size of coffee or you brew more than 4 cups for yourself, then there is no surprise you’ll feel a bit jittery and distressed. People who drink 1-2 cups a day in the early morning often don’t experience any of those problems and in fact there are even studies that show a decreased likelihood of depression in coffee drinkers. And drinking early in the morning as opposed to lunch makes an enormous difference on sleep.

    There are some potential issues with nutritional deficiencies, but curbing hunger might have a good impact as well in helping people become less likely to become obese and or develop type 2 in the first place.

    The one impact that further causes this article to lose credibility is that it left off the probably the most dangerous part of coffee, which is cafestol (a chemical found in coffee). This is why drinking unfiltered or french press coffee isn’t good for you. Cafestol raises cholesterol levels. The nice thing is that cafestol can be filtered out by using an unbleached paper coffee filter, eliminating that risk.

  12. I decided to search bad side effects of coffee after realizing that after drinking it, I am feeling closer to the dark side. Dont laugh, evil and demons are real and they stalk us like prey. I have drank lots of coffee since 6 grade. My mom is a starbucks addicts even sometimes going three times a day. Anyway I am 23 now and usually have a cup every day. However I became pregnant and the morning sickness and weird food cravings led me to not drink any coffee for a few months. I felt very repulsed by the thought of it and I drink all organic and w honey. So the other day I thought id have a cup for fun. Def noticed I had difficulty sleeping and also that now I am experiencing cravings for coffee all day. After just having one cup I went from repulsed to hooked!! That is a powerful drug!!! Also I am noticing feelings of evil. Its hard to explain, but I know the more u sin, the deeper into sin u will go. And it is clear to me that coffee is leading to sin. I know mayo clinic harvard etc say its ok but se riously ppl they cannot be trusted the authorities ARE ON RECORD TRYING TO DEPOPULATE THE EARTH AKA KILL US gosh theres so much to say about this but I will sum it up with YAHUSHA OF NAZARETH WAS ANNOINTED BY YAHUAH THE MOST HIGH TO FORGIVE OUR SINS A D BE OHR SALVATION. WHOEVER WALKS WITH THIS MAN YAHUSHA WILL NEVER WALK IN DARKNESS BUT WILL BE LOVED BY THE FATHER IN HEAVEN. I testify that this man yahusha has changed my life when I was not looking for him he found me a d saved me by tbe mercy of the most high. Seek the truth and turn from ur many sins and crookedness. Do not believe the trinity deception. All this christian churches are serving satan. Jesus christ is not the almighty this is a false doctrine of demo s. The truth is that yahusha is a man from israel who always please the creator and he has been given authority over all nations. Im at brent.stock at hot mail if u want to know more

  13. Research Gano derma and health affects it is now in coffee and the jitters, headache withdrawals are gone. Do yourself a favor change your coffee and change your life.

  14. Greetings! Very useful advice within this article! It’s the little changes
    which will make the most significant changes.
    Thanks for sharing!

  15. Read Caffeine Blues. It details the politics around coffee. Caffeine is handled like all other drugs, promoted by the pharmaceutical industry, etc. That’s why the medical field won’t make up it’s mind about the true dangers of it and why you keep seeing contradictory articles. This will keep happening, too, for many years to come. Imagine the businesses that would be affected if the truth were told: Hershey, Coca Cola, most soda companies, pill manufacturers, candy companies, coffee companies, etc. Coffee its the one legal drug that we can get away with using. Keep in mind that caffeine is categorized as a drug. What’s the average number of cups you can drink safely….well, what’s the average depth of a lake to someone who can’t swim? It’s sort of irrelevant, because coffee is so addictive that few people can stop at just one cup.

  16. Never have I had a problem with coffee! My heart is as sound now as it was when I was 20 – I am now 72! No kidney problems, none of the side effects listed! This is pure hogwash.

  17. Coffee is an everyday occurrence for most,very hard to let go of, but there is now a healthy coffee made from danoderma Lucidum; an all natural herb infused in your daily cup that has miraculous effects to the body’s health and longevity. You can find millions of studies on this herb called the “king of herb” or ” king of immortality” to understand more write this site down first to purchase your healthy cup today learn more by getting started. Teas and chocolate as well. Happy living!

  18. A very informative and insightful article. Never knew coffee had so many dangers to health!

  20. Coffee is the last thing anyone needs in this day and age. People who drink it everyday are storing up big problems. Caffeine effects people in more suttle ways than they realise. Since quitting I can think clearer, stay calmer and focussed for longer periods, avoid energy slumps and crashes and have a more balanced mood, and am sleeping like a baby. The problem is that it is a very seductive drink and so most people are in total denial, plus the Coffee companies are making billions so do you really think they are going to give you all the facts about this drug ?

  21. ALL the NEGATIVE EFFECTS that you have listed for Coffee consumption are ABSOLUTELY Factual and correct !

    And they have majorly confirm the latest findings and studies conducted which do not have marketing propaganda intertwined in it :)

    Anyone who Still believes otherwise, and that After EVERYTHING that coffee beans go through, including Severe roasting which produces mega amounts of cancirogens AND AGEs(Advanced glycation end-products) and forms many New and undesired molecular connections, is completely ignorant and oblivious to True Nature of Reality !

    I ALWAYS Have much more Focus, Mental Clarity, and constant energy throughout the day when I stay away from All caffeine, and especially Coffee !

    The Only TEA that is healthy and beneficial that i’m still experimenting with, is – 50/50 dried organic Stinging Nettle + dried org. Oat Straw

    Enjoy ;)
