What happens to your body when you drink coffee every day

Coffee is one of the drinks that some amateurs can not do without. Impossible for them to open their eyes and start their day without their morning elixir. So, this morning energizer knows how much coffee drinking is a complex and nuanced experience: its rich and powerful aroma, its comforting warmth and the pleasure of the ritual of taking time to savor it. Also, contrary to popular belief, drinking coffee every day can be beneficial for health as relayed by our fellow Doctissimo. We explain all of this in detail in this article.

The  coffee  is undoubtedly one of the most popular drinks in the world. But why do we like coffee as much? Because it makes us feel good. However, bitterness is not always a pleasant taste, and we usually try to avoid it. So, how to explain this contradictory love? 

Bitterness and coffee: A link established? 

In fact, according to a new study  by researchers at Northwestern University and published in the journal  Scientific Reports , coffee lovers are no less sensitive to bitter taste, on the contrary! Which indicates an interesting psychological phenomenon behind our love of coffee.

The team compared participants’ sensitivity to three different bitter flavors: caffeine, quinine, which gives sparkling water its bitter taste and propylthiouracil, a bitter synthetic compound. The scientists then discovered that people whose genes were very sensitive to quinine and propylthiouracil tended to drink less coffee. On the other hand, those sensitive to the bitterness of caffeine tend to drink more coffee. 

What happens to your body when you drink coffee every day

  1. Coffee makes you smarter 

Caffeine affects the central nervous system in several ways. In fact,  studies  have shown that caffeine can stimulate brain function in the short term. It also activates the central nervous system by promoting the release of several  neurotransmitters such as norepinephrine, dopamine and serotonin. Thus, it helps you improve various aspects of brain function including reaction time, alertness, learning and attention. 


  1. Coffee helps you reduce the risk of heart disease 

According to one  study , coffee consumption was directly associated with a lower risk of heart failure, stroke and coronary artery disease. Another  study  by researchers at the University of Colorado’s Faculty of Medicine found that for coffee drinkers, each cup of 20 cl per day reduced these risks by 7%, 8% and 5% respectively, compared to people who did not drink coffee. 

  1. Coffee helps you to be happier 

Several studies have shown that coffee can reduce the effects of depression. In fact, a  scientific report  examined the relationship between caffeine and depression in 346,913 people, 8146 of whom had  depression . Thus, the study was able to conclude that caffeine, particularly when it is present in coffee, acted considerably in the prevention of depression. 


  1. Coffee reduces your risk of developing type 2 diabetes

A study conducted by researchers at the Department of Endocrinology and Internal Medicine at Aarhus University Hospital in Denmark and published in the  Journal of Natural Products , found that  cafestol , a bioactive compound found in coffee, helped to increase the secretion of insulin. As a result, it helped to reduce fasting blood glucose and helped to improve insulin sensitivity and thus prevent you from developing type 2 diabetes. 

  1. Coffee protects you against Alzheimer’s disease 

Several   epidemiological studies in humans have suggested that regular coffee consumption reduces the risk of developing or at least delaying Alzheimer’s disease especially in the elderly. Nevertheless, coffee should be consumed in moderation, at the risk of doubling the risk of mild cognitive impairment, as reported in a study published in the  Journal of Alzheimer’s Disease . 

  1. Coffee could protect you against certain cancers

One  study  suggests that regular coffee consumption may reduce the risk of developing certain forms of  cancer  such as skin cancer. Nevertheless, the   United States Food and Drug Administration (FDA) recommends that adults not consume more than 4 cups of coffee per day. 

Thus, we can say that consumed regularly, but moderately, coffee can confer many health benefits. Nevertheless, coffee is not recommended for children, teenagers, pregnant or breastfeeding women.
