How many times have you heard that coffee dehydrates or causes stomach discomfort?
From the Coffee Ness blog, Arne Preuß, professional barista and founder of Coffee Ness, answers 5 questions that arise around coffee consumption. They will not leave you indifferent!
Our world is very polarized: it seems that everything can be very good or very bad depending on who we listen to or read. And given that we live in the era of misinformation, with the push of a button we obtain data and more data, which can sometimes be contradictory if we do not know how to discern well which information is of quality and which is not.
Well, the same goes for coffee and other foods or drinks. There are those who idolize him and curse him. And that is, in our opinion, what is truly risky: oversimplifying the benefits or risks of any food product. Is there no middle ground? Let’s go in search of him!
The first thing to do, in my opinion, in addition to researching reliable sources, is to use our common sense. We are going to list a series of questions about coffee that we have come across more than once and that we would like to think about carefully.
Does coffee cause dehydration?
When drinking coffee, what we ingest is made up of 98% water. Approximately 84% of the liquid that we consume when drinking coffee is evacuated without processing it. Only a few macronutrients from coffee remain in the body, and the caffeine passes into the bloodstream.
The diuretic effect of coffee stimulates the kidneys to produce more urine. Caffeine alone cannot draw fluid out of cells and out of the body. Therefore, it is impossible for you to dehydrate.
Likewise, there are studies that show that the diuretic effect of coffee is only perceived when drinking more than six cups and ends up disappearing when consumed regularly (this is known as tolerance).
Does coffee count towards daily fluid intake?
Food and drinks help us stay hydrated, but water and sugar-free infusions are the main sources of fluid intake and the most recommended when it comes to keeping our body in shape from a water point of view.
And it is that everything else can contribute to the daily intake of liquids, but you have to be careful with the side effects of said intake. That is, drinking several liters of cola every day will give us a lot of water, but it will end up creating problems with obesity, among other things.
Well, the same goes for coffee. Although coffee provides fluids to our body, we should focus on the delight instead of stressing ourselves thinking if it will help us to have the minimum covered or not.
Does coffee raise blood pressure?
The debate surrounding the question of whether or not coffee increases blood pressure is well known. The latest studies on the subject show that caffeine only minimally raises blood pressure, and only until tolerance occurs.
According to the Spanish Heart Foundation, people with controlled hypertension could drink up to 3 or 4 cups of coffee a day, “since its harmful nature in relation to cardiovascular pathology has never been demonstrated,” says Dr. Enrique Galve, President of the Vascular Risk and Cardiac Rehabilitation Section of the Spanish Society of Cardiology (SEC)
Does coffee cause stomach upset?
There are people who notice gastrointestinal discomfort just by taking a sip of coffee and there are those who can drink it by the gallon and feel nothing.
It has been associated that chlorogenic acid (caffeic acid ester, present to a greater or lesser extent depending on the variety of coffee) could be the cause of these problems.
However, the highest concentration of this acid occurs, above all, in the raw bean, and it is considerably reduced during the roasting process. And, the slower and more careful this process is, the more it will be reduced.
Anyway, as in everything, the dose makes the poison! In the cup, the dose of chlorogenic acid is tiny, so it may or may not cause stomach problems.
Conclusions: is coffee healthy or not?
We must bear in mind that coffee is not a medicine, if so, it should be accompanied by a leaflet, nor is it a harmful substance. There are no warnings (graphics) on coffee packages.
In this post from the Mayo Clinic, answering the question of whether or not coffee is beneficial to health, the expert appeals to common sense and invites us to observe our own bodies to see if coffee is good for us or not.
In the words of Donald Hensrud, MD, having a coffee habit is not harmful and could even have benefits, but if we notice certain side effects such as heartburn, nervousness, or insomnia, we should consider reducing it.
Of course, certain risk groups, such as pregnant and lactating women or people with very high blood pressure, should certainly minimize and control their coffee consumption. Like everything, coffee should be enjoyed in moderation and common sense!
