Coffee is one of the most popular drinks around the globe. Most of us start the day by drinking a cup of it, but not many of us know what does coffee do to the body. This substance has both positive and negative effects. Let’s take a look at what it is, how much is good for you and what it does to you.
Types of coffee:
The largest coffee producer in the world is Brazil followed by Vietnam. There are two primary sorts of coffee plants. Those are Robusta and Arabica.
Presently, over 75 percent of all the coffee beans produced on our planet come from Arabica plant. However, Robusta is rapidly catching up, as it is more resistant to diseases.
At this the quality of coffee beans from Robusta or lower than that of Arabica. There is the roasted coffee and “green”, which simply means the beans have been dried up, but not roasted.
The green ones preserve more antioxidants in them and thus deemed healthier. Of course, there is the instant coffee to consider and there is the decaf one.
How is instant coffee made?
The instant one is made either by boiling coffee beans and then spraying the solution up into dry air. When it drops down, all the moist gets soaked out of it and we get the instant coffee powder. The second method involves freezing, when moist is pressed out using special chemicals.
How is decaf coffee made?
One of the methods of extracting the caffeine from coffee beans applied done by steeping green ones in hot water and then adding chemicals to dissolve and remove caffeine. The second method involves using steam instead of hot water, but the beans also get treated with certain chemical solutions.
There are other methods used to attain the desired result. It has to be mentioned that those chemical agents used for decaf are not very healthy and along with caffeine they destroy vitamins and antioxidants contained in this drink.

- Helps to stay alert
Caffeine makes your blood vessels to narrow down, which increases the blood pressure. Plus, it affects the adrenaline glands and sort of turns on the “fight or flight” reaction. That is how it keeps you awake. Such effects of coffee become obvious in about 15 minutes after you have your cup of coffee. Caffeine stays in your body for over 6 hours, and then it washes away.
Some of the most recent studies show, that regular consumption of coffee can reduce cancer risks by up to 60%! Coffee is rich in anti-oxidants, which fight free radicals and help your body to restore faster. At this, the amount of daily coffee should start at 2+ cups (up to 6 cups a day) to have such a great anti-cancer effect.ъ
Prevents heart diseases
Over time our blood vessels tend to accumulate calcium deposits and get blocked. That leads to various heart diseases, such as coronary heart disease. Taking up to 5 cups of coffee per day may help you wash out those deposits and keep your vessels clean and healthy.
Helps you burn fat
Caffeine boosts your metabolisms and consequently helps burning more calories throughout the day. Its effects are more obvious in lean people, but they can boost up your calorie burning by 10% even if you have considerable amount of excessive pounds.
There are two prominent positive effects of coffee on your digestion system. One of them involves lower absorption of sugar.
This means you digest fewer calories and stay leaner. The second one is related to speed food down the tract and relieving constipation. This helps you to detox and stay healthy.
Over stimulates adrenalin glands
Adrenalin launches a very important reaction in the body: flight or fight one. It helps you to react properly in dangerous situations and sends more blood to your muscles. Plus, it stimulates your nervous system. Abuse of caffeine may lead to overstimulation of nerves and constant fatigue. This same reaction may evoke addiction to caffeine, when you need more and more of it to keep you energized and feeling well.
Creates caffeine addiction
As it was already mentioned caffeine is the most abused and commonly used drug on our planet. It has become part of our daily culture. The fact that caffeine forms addiction was discovered and finalized in 1994. The problem with this substance is that its formula is very similar to adenosine – a substance produced by the brain.
Caffeine successfully blocks the glands receptive to adenosine (responsible for the sense of tiredness). Thus, we keep on feeling energized even when we do get tired. If we rapidly stop the intake of caffeine, we experience excessive levels of fatigue. The withdrawal symptoms may involve nausea and even muscle pains (flu like condition).
Most people have the tolerance rate to caffeine at about 200-300 mg per day. Some people are too sensitive and perceptive to this substance and 200 mg is too much for them. In the case you exceed the normal dose of it caffeine may evoke hand tremor (shaking), as one of its side effects.
Increases heart rate and blood pressure
First of all caffeine impacts your adrenaline glands and makes your heart beat faster. Then it narrows down your blood vessels. Now you have more blood running down the veins, but they stay narrowed down. This may lead to brain stroke or blood vessel eruptions. It may happen in one’s brain or elsewhere. That is why you may have nose bleeding after excessive intake of coffee.
Washes out key elements and minerals
It may reduce the absorption of vitamin C and other essential nutrients, such as calcium, etc. Thus scientists do not recommend drinking coffee along with your main meals. Let your body digest the food and get all the nutrients out of it and then take coffee breaks in between the meals.
How much coffee is good for you?
In average one cup of brewed coffee contains about 100mg of caffeine. According to scientific data up to 4 full cups a day is good for most adults. Exceeding the norm of 400mg on daily basis may lead to caffeine addiction and other side effects described above. This is the case, if you are not too sensitive to caffeine or your age is under 70 years.
