Belief in draining coffee is believing many

The misconception of dehydrating coffee is still widespread today
For decades, coffee consumption has been viewed critically from a health point of view, but in recent years, more and more positive health effects have come to the fore and common misconceptions have been refuted. So too the assumption that coffee withdraws water from the body.

In many cases, coffee has been described in the past as having a negative effect on the fluid balance. He should therefore find no credit for the daily fluid intake. But this assessment is now obsolete. Because the coffee is very well fluid and the supposed dehydrating effect is not as strong as previously thought. Coffee does not draw water from the body, but is to be evaluated as a liquid dispenser.

Coffee can be counted in the fluid balance
The assumption that coffee has a negative effect on the fluid balance, according to Helga Strube of the German Society of Nutrition (DGE) - Lower Saxony results on the wrong interpretation of earlier study data, according to the news agency "dpa". By the amount of water supplied regular and uniform coffee consumption of course influence the liquid balance and he could be confidently counted in the "fluid balance"; Strube is quoted by the "dpa". Although the caffeine promotes the urinary excretion and the sodium release via the kidneys, but moderate consumption of four cups per day, this is compensated by the body again. A prerequisite is, however, that enough is drunk enough, as a rule of thumb at least 1.5 liters are to be set. A glass of water for coffee is not necessary, but it is a good tradition. Coffee should - despite the credit to the fluid balance and other positive health effects - in the opinion of the DGE expert consumed as a stimulant and not as a thirst quencher.

Protection of the genome and improved potency
The positive health effects of coffee, which have recently come to the fore, include, for example, the protective effect on the genetic material. For example, scientists from the University of Kaiserslautern have found that regular coffee consumption protects the DNA from harmful strand breaks and thus from negative environmental influences. The researchers also saw this as a possible explanation that coffee has been shown to protect against certain cancers. For men, coffee consumption has a positive effect on potency, according to a study by researchers at the University of Texas (UTHealth), published in the late May issue of the journal PLOS ONE. In addition, there are numerous other positive health effects of the once so demonized drink. Here, therefore, a differentiated view is required. While coffee consumption can be detrimental under certain conditions, moderate consumption usually outweighs the positive effects. (Fp)
