For the head, yes; For the body… not for that.
Brands, there are many to choose from, and many people can differentiate the flavor from water – although many others find the concept of enjoying waters a “mesquinhice”.
But are there types of waters that do better to health than others?
Between alkaline water, with electrolytes, “improved”, flavored and even experts guarantee: There is no evidence that these waters are more beneficial to most people.
“There is no physiological basis that suggests some metabolic benefit in these special waters compared to ordinary water, ”says the scientist Roger Fielding at the University of Tuffs.
But that It does not mean that we should not consider Well the water we choose to drink. “If you have a preference for water and it makes you drink more and make it more attentive to rehydration, and have the resources to buy it, then do it,” explains Fielding.
Despite everything, there is a nutritional aspect to take into account: the sodium content. Some waters with electrolytes may contain high sodium levels, which in large quantities may increase the risk of hypertension and other cardiovascular problems.
Even for athletes or people who exercise in intense environments, it is difficult to develop deficiencies of electrolytes. Our body rigorously regulates the concentration of electrolytes in the blood and cells, which means that drinking water with electrolytes rarely changes this balance.
The water Alkalinefor example, which is often promoted as beneficial to bone and muscle health, also does not have clear evidence of effectiveness.
However, in the elderly with diets rich in acidifying foods – As meat and cereals – there may be some logic in looking for alkaline sources, since the kidneys lose capacity as we get older, to regulate the pH.
For the elderly population, with a lower sensation of thirst or with liquid intake difficulties, flavored waters or other variations can help maintain proper hydration. But we never made mistakes when choosing the most popular, natural water.
