Things to know about the negative effects of coffee

Millions of people around the world enjoys and loves coffee. Whether it is the conventional type or those sophisticated premium quality cup, coffee is the usual morning companion for a lot of people.

Aside from its great taste and enticing aroma, coffee has numerous benefits - including health related advantages. Unfortunately, for any positive factors, there is a seemingly corresponding negative counterpart. This is the common argument of most people who does not share the same liking to coffee.

Yes, coffee may have some negative effects, however, what these people failed to realize is that for the unwanted effects to kick in, certain conditions must be met. This post aims to showcase some (but common) negative effects of coffee as well as the conditions on how the undesired effect will be produced.

First off, it has been long established that there is a relationship between coffee and sleeping because of caffeine - a major component of coffee. Depending on a person's digestive system, it typically takes around 6 hours for the said substance to be cleared out of the body. Recent studies also showed that this sleep depriving effect will worsen with age.

The one mentioned above may be perceived as negative for some but positive for others. There are certain people who drink coffee to stay awake for different reasons. Nowadays, there is a special type of coffee called decaf coffee – obviously, this is a kind of coffee with lesser caffeine. For the readers who want to enjoy coffee but not the side effect mentioned above, then simply enjoy a great tasting coffee during the morning or opt to go for a decaf.

Coffeea arabica beans are found out to contain a certain quantity of cafestol – with higher amounts discovered on boiled or unfiltered coffee. Cafestol is a compound that apparently increases blood levels of LDL cholesterol. This is the reason why a few people would suggest going for filtered coffee. Besides, coffee is not the sole contributor for high blood and high levels of cholesterol. It actually depends on a person's eating habits and lifestyle.

Caffeine interferes with adenosine. Adenosine is a brain chemical that provides a calming effect. It is for this reason that people who consumed high dosage of coffee appear to be jittery or irritated. However, please take special note of the statement "high dosage consumption". Needless to say, the saying “too much of everything is not good” also applies to coffee. Enjoy and appreciate the drink, but be sure not to abuse and be addicted to it.

That's about it for this post. There may still be other negative effects of coffee but for sure, there are ways on how to go around it and still enjoy a premium quality cup of coffee.
