A study from St Andrews University in Scotland has just deconstructed all our accepted ideas: water would not be the most moisturizing drink. No, no!
You thought you knew everything about hydration? This information will surprise you. According to researchers at St Andrews University in Scotland, water, whether it is flat or bubbly, is not the most moisturizing drink. If it acts directly on the body, it is not as effective as beverages that contain a little sugar, fat or protein that hydrates better and longer.
According to Ronald Maughan, a professor at St Andrews Medical School and lead author of the study, this phenomenon is linked to the way our body reacts to liquids. Because drinking water is good, but it is still necessary that the liquid is absorbed properly by the body. And in this company, milk is much more effective thanks to the lactose, proteins and fat it contains. Sodium also allows it to act like a sponge, reducing urine production and keeping the water longer.
At the risk of disappointing you, sodas and fruit juices remain less moisturizing than milk and water because they contain far too much sugar. And for those who wonder, for alcohol, everything depends on the amount absorbed. “The beer would be less water loss than the whiskey, because you ingest more liquid with the beer.The drinks with strong alcohol dehydrate, not diluted alcoholic beverages,” says Ronald Maughan. And for coffee, it’s the same thing. According to the authors of the study, an espresso would be as effective as a glass of water to rehydrate. You know now what to drink in the aftermath of the evening.
