The facts and myths about coffee

The black gold, a cup drop a cup of joe: coffee is a drink that is like being drunk, but also ambiguities and even fables. What is true and what is not? NU.nl put it on a list.
Is coffee healthy?

“Yes,” says Ellen Kampman, professor of Diet and Disease at Wageningen University & Research (WUR). They examine the effects of coffee on the long-term. “Coffee can have a beneficial effect on many chronic diseases, such as diabetes, heart disease and certain forms of cancer.” A overzichtsstudie of Harvard University from 2017 confirms this.

It’s not something many people expect to coffee, says Kampman. “I hear sometimes people complain that the coffee is actually not good. It is sometimes associated with smoking and other bad habits. But I want to rid of that image: coffee fits into a healthy diet and provides beneficial effects on several forms of diseases.”

The way in which your coffee is important. Coffee from a cafetière, placing the coffee down, is not so healthy. “By this way of putting, there are fats such as cafestol in the coffee, which in turn means bad cholesterol. So that is not too much to drink.”

Coffee is included in the Disc of Five. “It fits within the guidelines of good nutrition,” says Astrid Postma, voedingsexpert at the Nutrition centre. “Two to four cups of coffee a day lowers the risk of heart disease, stroke and diabetes.”

What causes that coffee is healthy?

It is not known which substances the coffee healthy, says both Kampman as Postma. Is it the polyphenols or antioxidants? In any case, it’s not the caffeine, because decaffeinated coffee is just as healthy. The WUR is in the preliminary phase of the investigation of what coffee exactly make it healthy. That is not so easy, because there must be taken into account many factors. It does matter how people drink their coffee with or without milk or sugar – and how the coffee is roasted.

However, there is a hypothesis about what coffee does in your body. “We think that the drink has a beneficial effect on fatty liver,” says Kampman. “With obesity and an unhealthy lifestyle can fat arise around bodies. We think that tea makes for a reduction of fatty degeneration around the liver, because all the diseases to which the coffee has a favourable effect on the fatty.”

You become restless of coffee?

The caffeine in coffee, makes for a stimulating effect and makes you more alert, says Postma. The Nutrition centre recommends a maximum of about four cups per day. “Above may the caffeine make for restlessness and heart palpitations. But not everyone is equally sensitive to, and it is not dangerous.”

“Caffeine can indeed for people a variety of things, because it is genetically determined is how we caffeine in our body converting,” says Kampman. “Some people can sleep like a log after a few cups of coffee, others do not. This has partly to do with how quickly you caffeine can break down in your body and how quickly you make it out of bed.”

Extracts coffee moisture away from the body?

That coffee moisture to your body extract, is a myth, says Kampman. “I hear much talk about. But coffee drinking is a good way to get some moisture to get inside.”

Does coffee affect your bowel movements?

“A part of the people think that coffee has an effect on your bowel movement, but in studies, this is not really hard proven,” says Postma. That agrees Kampman. There is, in any case, no consensus is also evident from this article in the Volkskrant. However, in this article concluded that coffee something to do with your intestines. But what? That is not clear.

Do you get headaches when you stop drinking coffee?

“Normally if you had a few cups of drinks per day, and suddenly stop, you can suffer headaches,” says Postma. This is located at the stop of the supply of caffeine, according to research from the Radboud University in Nijmegen.

If you’re all drinking lots of coffee stops, the headache in addition, may also be associated with less moisture in their diet, says Kampman. “You’re also a headache.”

Should pregnant women not drink coffee?

The Nutrition centre (voedingscentrum) advises pregnant women to one cup of coffee per day. “If pregnant women, too much caffeine, this can lead to a lower birth weight for the baby,” says Postma. Decaffeinated coffee is a good replacement.

Is decaffeinated coffee healthier?

Coffee without caffeine is just as healthy as regular coffee and ensures the same health effects, says Kampman. “Caffeine is not per se undesirable.” The amount of caffeine that you take in, of course it’s important, adds Postma. Three to four cups per day is the guideline.
