The effects of coffee on health | Good or Bad?

The effects of coffee on health are controversial. Despite what you’ve heard, there are many good things to say about coffee. It is rich in antioxidants and is associated with a reduced risk of many diseases.

However, it also contains caffeine, a stimulant that can cause problems for some people and stop sleep. This article examines coffee and its effects on health in detail, examining both the positive and the negative aspects.

Coffee contains some essential nutrients and is extremely rich in antioxidants

Coffee is rich in many nutrients found naturally in coffee beans.

A typical 8-ounce cup of coffee (240 ml) contains:

Vitamin B2 (riboflavin): 11% of the DV

Foliate: 1% of the DV

Vitamin B5 (pantothenic acid): 6% of the DV

Potassium: 3% of DV

Vitamin B1 (thiamin): 2% of the DV

Magnesium: 2% of DV

Vitamin B3 (niacin): 2% of the DV

Manganese: 3% of DV

Phosphorus: 1% of DV

It may not seem like much, but try to multiply it by the number of cups you drink every day – this can be an important part of the daily nutrient intake.

But coffee really shines because of its high antioxidant content. In fact, the typical Western diet provides more antioxidants from coffee than fruit and vegetables combined.


Coffee contains a small number of vitamins and minerals, which are added if you drink several cups a day. It is also rich in antioxidants.

Espresso Contains Caffeine, a Stimulant That Can Enhance Brain Function and Boost Metabolism

Caffeine is the most generally devoured psychoactive substance on the planet. Soda pops, tea and chocolate all contain caffeine; however, espresso is the greatest source. The caffeine substance of a solitary container can extend from 30– 300 mg, however, the normal glass is someplace around 90– 100 mg.

Caffeine is a known stimulant. In your cerebrum, it hinders the capacity of an inhibitory synapse (mind hormone) called adenosine. By blocking adenosine, caffeine expands movement in your mind and discharges different synapses like norepinephrine and dopamine. This lessens tiredness and makes you feel more alarm.

Various investigations exhibit that caffeine can prompt a transient lift in cerebrum work, enhancing mind-set, response time, watchfulness and general intellectual capacity. Caffeine can likewise support digestion by 3– 11% and practice execution by 11– 12%, by and large.

Be that as it may, a portion of these impacts are likely here and now. On the off chance that you drink espresso consistently, you will develop resilience — and with it, the impacts will be less ground-breaking.


The fundamental dynamic compound in espresso is the stimulant caffeine. It can cause a fleeting lift in vitality levels, mind work, metabolic rate, and exercise execution.

Coffee can protect the brain against Alzheimer’s and Parkinson’s

Alzheimer’s disease is the most common neurodegenerative disease in the world and one of the main causes of dementia. Past researches have shown that coffee drinkers are still 65% fewer likely to develop Alzheimer’s disease.

Parkinson’s disease is the second most common neurodegenerative disease. It is caused by the death of dopamine-producing neurons in the brain. Coffee drinkers are likely to reduce Parkinson’s by 32-60%. The more people drink coffee, the lower the risk.


Several studies show that coffee drinkers have a much lower risk of dementia, Alzheimer’s and Parkinson’s in the elderly.

Coffee drinkers have a very low risk of type 2 diabetes

Type 2 diabetes is characterized by high levels of blood sugar that are resistant to the effects of insulin. This common disease has increased the senile decade in recent decades and now has over 300 million people.

Note that studies show that coffee has a 23-67% risk limit for developing this condition. An evaluation of 18 studies involving a coffee with 457.922 people at the same time each day with a risk of type 2 diabetes reduced by 7%.


Many studies have shown that coffee drinks have a significantly reduced risk of type 2 diabetes.

Coffee drinks have a lower risk of liver disease

Your body is an unfortunate body that has hundreds of different functions in your body. It is sensitive to alcohol and fructose monitoring. The interruption of transport damage is called cirrhosis and means that most of your liver is in the nervous tissue.

Coffee drinks have a lower risk of cirrhosis up to 84%, with the strongest effect for those who drink 4 or more cups a day. The liver is also common. It is the most important cause of cancer in the world. Coffee drinks have up to 40% less risk of cervical cancer.


Coffee drinks have a significantly lower risk of sclerosis and liver cancer. The more coffee you drink, the army is the risk.

Coffee drinks have a much lower risk of depression and suicide

Depression is the most common mental disorder in the world and leads to an expressively reduced superiority of life. In a 2011 Harvard study, individuals who drank most of the coffee had a 20% minor risk of depression. In a study of three studies, persons who drank four or more cups a day had 53% less expected to commit suicide.


Studies show that people who drink coffee have a lower risk of being depressed and less likely to commit suicide.

Some studies show that coffee drinkers live longer

Because coffee drinkers are less likely to develop many common killer diseases – as well as suicide – coffee could help you live longer. The long-term research of 402,260 people aged 50 to 71 revealed that coffee drinkers had a much lower risk of death in the 12-13 year study period. The ideal area seems to be 4 to 5 cups a day, with men and women having a 12% and 16% reduced risk of death respectively.


Some studies show that, on average, coffee drinkers live longer than non-drinkers. The strongest effect is observed from 4 to 5 cups a day.

Caffeine can cause anxiety and stop sleep

It would not be fair to speak only of good without mentioning evil. The truth is that there are also negative aspects of coffee, even if it depends on the individual. Eating too much caffeine can be a source of nervousness, anxiety, heart palpitations and even exacerbated panic attacks.

If you are sensitive to caffeine and tend to be overstimulated, perhaps you avoid coffee altogether. Another side effect is that it can interrupt sleep. If coffee is bad for sleep, try doing it at the end of the day, for example after 2:00 pm.

Caffeine can also have diuretic and hypertensive effects, although these usually dissipate with regular use. However, a slight increase in blood pressure of 1-2 mm / Hg may persist.


Caffeine can have various negative effects, such as anxiety and sleep disorders, but it depends a lot on the individual.

Caffeine is addictive and the lack of some cups can cause withdrawal

Another problem with caffeine is that it can lead to addiction. When people consume caffeine regularly, they become tolerant. Either it stops working normally, or a larger dose is needed to produce the same effects.

When people abstain from caffeine, they experience withdrawal symptoms such as a headache, exhaustion, brain fog and irritability. This can take a few days. Tolerance and withdrawal are the characteristics of physical dependence.


Caffeine is a substance that is addictive. This can lead to well-documented tolerances and withdrawal symptoms such as headache, fatigue, and irritability.

The difference between regular and decaffeinated

Some people opt for decaffeinated coffee instead of regular ones. Decaffeinated coffee is usually prepared by rinsing coffee beans with chemical solvents.

Whenever the beans are rinsed, a percentage of the caffeine dissolves in the solvent. This process is repeated until most of the caffeine has been eliminated. Remember that decaffeinated coffee also contains caffeine, much less than normal coffee.


Decaffeinated coffee is obtained by extracting the caffeine from the coffee beans using solvents. Decaf does not have all the same health benefits as regular coffee.

How to maximize health benefits

You can do some things to maximize the health benefits of coffee. The most important thing is not to add a lot of sugar.

Another technique is to make coffee with a paper filter. Unfiltered coffee, especially from the Turkish or French press, contains cafestol, a substance that can increase cholesterol levels.

Remember that some coffee drinks in cafes and franchises contain hundreds of calories and lots of sugar. These drinks are unhealthy if they are consumed regularly. Finally, be careful not to drink too much coffee.


It is important not to put a lot of sugar in the coffee. Brewing with a paper filter can get rid of a compound called cholesterol called cafestol.

Do you have to drink a coffee?

Some people, especially pregnant women, should absolutely avoid or greatly limit the consumption of coffee. People who suffer from anxiety, high blood pressure or insomnia may also want to reduce their consumption for a while to see if it helps. It also appears that people who metabolize caffeine are slowly at increased risk of heart attack after drinking coffee.

In addition, some people worry that coffee consumption increases the risk of cancer over time. It is true that roasted coffee beans contain acrylamides, a category of carcinogenic compounds, but there is no indication that the small amounts of acrylamides in coffee are harmful.

In fact, most studies suggest that coffee consumption has no effect on cancer risk and could even reduce it. That said, coffee can have significant beneficial effects on the health of an average person.


If you do not drink coffee, these benefits are not a convincing reason to start doing so. There are also disadvantages. But if you already drink coffee and have fun, the benefits seem to far outweigh the disadvantages.

The final result

It is important to keep in mind that many of the studies mentioned in this article are observational. They examined the link between coffee consumption and the consequences of the disease, but they proved neither cause nor effect.

However, because the association is strong and consistent between studies, coffee can actually play a positive role in your health.

According to scientific evidence, coffee is probably very healthy for most people, even if it has been demonized in the past.

In contrast, coffee belongs to the same category of healthy drinks like green tea.
