Is Coffee Good or Bad For You? The Pros & Cons of Coffee Drinking


Do you like coffee? I do, it's taste and aroma make my mornings so much better! But I heard that regular coffee drinking can have some negative effects on my health, so I decided to do my own little research and here is what I have found:

Coffee Pros

  • 1. Antioxidants. Coffee is rich in antioxidants like chlorogenic acid and melanoidins. Antioxidants help prevent oxidation, a process that causes damage to cells and contributes to aging.
  • 2. Parkinson's disease. Regular coffee drinking reduces the risk of Parkinson's disease. A number of studies [1],[2] have demonstrated that people who drink coffee on a regular basis are significantly less likely to develop Parkinson's disease.
  • 3. Diabetes. Coffee drinking has the potential to protect against the development of type 2 diabetes. A prospective study[3] as part of the US Nurses Health Study found that moderate consumption of both caffeinated and decaffeinated coffee may lower the risk of type 2 diabetes in younger and middle aged women.
  • 4. Liver cirrhosis. Coffee drinking may protect against liver cirrhosis, especially alcoholic cirrhosis.
  • 5. Gallstones. There is some evidence [4] that coffee drinking may be protective against gallstone formation in both men and women.
  • 6. Kidney stones. Coffee consumption lowers the risk of kidney stones formation. Coffee increases the urine volume, preventing the crystallization of calcium oxalate, the most common component of kidney stones.
  • 7. Improved mental performance. Caffeine in coffee is a well-known stimulant. Coffee promotes alertness, attention and wakefulness. The cup of coffee can also increase information processing.
  • 8. Alzheimer's disease. Regular coffee drinking may help to protect against Alzheimer's disease. Recent study [5] in mice showed that caffeine equivalent to 5 cups of coffee per day reduced the build up of destructive plaques in the brain.
  • 9. Asthma. Caffeine in coffee is related to theophylline, an old asthma medication. Caffeine can open airways and improve asthma symptoms.
  • 10. Caffeine safety. In 1958, caffeine was placed on the Food and Drug Administration's list as generally recognized as safe.

Coffee Cons

  • 1. Heart disease. This is somewhat controversial. Most prospective cohort studies haven't found that coffee consumption is associated with significantly increased risk of cardiovascular disease.

    On one hand, diterpenes cafestol and kahweol present in unfiltered coffee and caffeine each appear to increase risk of coronary heart disease. High quality studies [6] have confirmed the cholesterol-raising effect of diterpenes. Also, coffee consumption is associated with an increase of plasma homocysteine, a risk factor for coronary heart disease.

    On the other hand, a lower risk of heart disease among moderate coffee drinkers might be due to antioxidants found in coffee.

  • 2. Cholesterol. Heavy consumption of boiled coffee elevates blood total and LDL ("bad") cholesterol levels [7]. Unfiltered coffee contains two cholesterol-raising compounds cafestol and kahweol.
  • 3. Blood vessels. Coffee negatively affects the blood vessel tone and function.
  • 4. Heart rhythm disturbances. Coffee can cause rapid or irregular heartbeats (cardiac arrhythmias).
  • 5. Blood pressure. Although coffee drinking is not a significant risk factor for hypertension, it produces unfavorable effects on blood pressure [8] and people prone to hypertension may be more susceptible. Recent Italian study found that coffee drinking can slightly increase the risk for development of sustained hypertension in people with elevated blood pressure.
  • 6. Osteoporosis. Coffee intake may induce an extra urinary excretion of calcium. Heavy coffee consumption (600 ml or more) can modestly increase the risk of osteoporosis, especially in women with a low calcium intake [9].
  • 7. Heartburn. A cup of coffee can trigger the heartburn.
  • 8. Sleep. Most are aware of the stimulatory effects of caffeine. High amounts of caffeine taken before going to sleep can cause difficulty falling asleep, tendency to be awakened more readily by sudden noises, and a decreased quality of sleep. However, some people can drink coffee and fall right asleep.
  • 9. Dehydration. The caffeine in coffee is a mild diuretic and can increase urine excretion. This effect may be easily neutralized by drinking an extra glass of water.
  • 10. Dependence. Although "generally recognized as safe" by the FDA, caffeine is still a drug, a mild central nervous system stimulant, and it produces dependence. Caffeine withdrawal is a real syndrome. You may get a few days of headache and irritability if you choose to quit drinking coffee, however, it is relatively easy to break this habit, and most people are not addicted to caffeine.

Seven years ago, I wrote a comment about coffee and I felt good reflecting back at the comment I made about my finding about coffee. I have grown to know that an 100% Arabica coffee are good and do not smell in our body, urine and mouth. "The origins of Arabica coffee that's 100% genuine is from Ethiopia and Yemen. This coffee is the first of its kind that is said to have been grown for thousands of years south west of Arabia. Arabica that is 100% authentic coffee beans are the most popular and are considered the world's best coffee. There is no other coffee bean product that can match the 100% genuine Arabica coffee". A word from the wise, Do everything in moderation!

I love coffee because it makes my day. It is the only thing I miss if I travel away from home. The thought of coffee wakes me up in the morning.

Katie on August 18, 2013:

Thanks. I'm writing a speech about coffee and this is perfect. Also great to see what coffee can help with.

Susette Horspool from Pasadena CA on June 27, 2013:

Coffee dilates blood vessels, which can be good in some situations and not so good in others. If too many vessels are dilated too long, it reduces pressure in the vessels and makes the heart work harder to get the blood around the body - hence the danger of heart attacks (or failure). That said, for most of us that's not a problem, because we don't drink enough.

I like coffee. I drank it more when I lived near Starbucks than I do now out in the boonies. However, there was a time when I was repetitively getting canker sores in my mouth. I wondered if they were caused by too much acid, so I stopped drinking coffee and green tea for awhile (which are acidic). It worked right away and has continued to do so. Now I'm careful to keep coffee drinking in balance.

For me personally the pro's far outweigh the cons.

I'm 20, I do not have cholesterol issues, I eat very healthy foods. So that factor would not affect me.

I suffer low blood pressure at times, recently went to the doctor and it was 74/70 or something close to that. Then did a retest half an hour later and it was more normal. So in that regard coffee would help me.

I have good calcuim intake so osteoporosis would not occur, most likely.

I also have a good water intake and only have 1 cup of coffee every 2 or 3 days

I am a coffee lover...and glad to read this article and knowing the benefits and cons. of coffee in ourselves..thanks to all the pros..and to all the coffee mates that share their comments.

I heard coffee gives you F.B.D. (frequent boner disease) And I have suffered a long time. but I have found a cure ;)

Manav Agarwal on May 22, 2012:

I strongly thing the person who has written this article is a coffee lover, but sorry to say you wrong because what ever god things you mentioned about coffee is that it can help slightly reduced some of the symptoms of a diseases but to tell you all this information about the benefits of reducing the diseases is just the experiment and observation on patients. The scientist them self do not have the commendable reason for this. While talking about the caffeine it is an intoxication it will seriously effects our brain, and what ever immediate effect you see will not going to last for long but simultaneously it will decrease your mind capacity make you addicted and you will never be able to realize that. In Indian Vedic literature it is clearly written which ever thing is intoxication in very dangerously for mental ,physical and spiritual health.

Jacob on May 15, 2012:

What hasn't been mentioned here is that coffee can really stain your teeth. Also it really gives people bad breath. I still love coffee but be sure to have some mint gum on you for afterwards. Nothing worse than going to a meeting and having to deal with coffee breath.

As the cultivation of coffee gained momentum, many coffee shops also came into being. After Yemen, coffee made its way to Egypt, Saudi Arabia and then to every other place in the world. Coffee has a wonderful aroma and taste that can make any one drool over his knees. No matter how tasty this beverage is, over consumption of coffee will ultimately cause adverse effects on the human body. If coffee is consumed moderately, than one cannot only enjoy its rich taste but also numerous benefits as well. Today, gano coffee is becoming a popular choice in the hearts of the health conscious people. Ganoderma Coffee is a much tastier and healthier variety of coffee.

The Ganoderma Coffee is rich in anti-oxidants which help in regulating the cancer causing cells in the body. This is readily available at most of the leading coffee shops. There is great news regarding this variety of coffee, that it is cheaper than the ordinary coffee.

It keeps the cells fresh and removes all the free radicals that are the toxic for the human body. The Ganoderma Coffee also works wonders in removing the symptoms of depression and indigestion. It is also greatly beneficial in boosting the metabolic rate of the body. The Gano Coffee also helps in preventing Parkinson’s disease and combats cancer. It drastically reduces the excess moisture from the body, thereby facilitating the waste removal from the body.

The ganoderma coffee offers plenty of health benefits to all its drinkers. Every sip of Gano Coffee can help us in keeping various health problems at bay. Ganoderma Lucida is also known as the ‘wonder herb’ and it has been in regular use by the people of China and Japan for past so many centuries. The emperors of these countries used the extracts of this herb in tea. They believed that this herb will get vitality and long life to them. Today, all the health benefits of this wonder herb can be easily enjoyed through coffee Ganoderma. The anti-oxidants and anti-biotic properties of this herb can increase the health benefits of coffee manifolds. It helps in regulating the blood sugar and blood pressure levels as along with slowing down the aging process.

I like this article, thanks to the one who posted it, but I still love to drink coffee, for me too much of everything is not good, so to all coffee lovers like me, lets drink moderately. :D

twocans on March 31, 2012:

What people also need to remember it is very easy for coffee to increase your alcohol intake. I found it common to have between 6 and 10 ish cups of instant coffee every day, the latter ammount in the winter as it was cold and sometimes heathing would not be enough. Any way I found by drinking so much coffee I became desperate for alcohol in the evenings to wind down. It was the noraml maybe 3 cans of 5% larger and perhaps 3/4 bottle red wine. Glady I am off the coffee for near 2 weeks and the urge for drinking so much has gone. I can easily now do 3 small cans a larger a week and not find that there is is something missing from my life. Thus if you drink too much alcohol (you know who you are)..... then cut out the coffee ahhhhhhh it is so so addictive but enjoyable to say I shall never drink it again.

Is three cups to much

Scott Tiedman on January 06, 2012:

This was a very informative article, but if you had actually looked at people who drank coffee you'd see that they look much older than their actual age, and this is do to the amount of wrinkles and tone of the skin. Not only this but one other con is the fact that coffee sends your stomach through the same process as hide goes through when it is being tanned to make leather.
