A study shows that drinks are even more hydrating than water, thanks to the combination of proteins, lactose and sodium, which help the body retain liquids for longer
When we talk about hydration, water is always the first thing that comes to mind. Essential for life and involved in virtually all functions of the human body, it is often considered irreplaceable. But, according to research conducted by St. Andrew’s UniversityIn Scotlandthe title of “most hydrating drink” goes to another liquid: skimmed milk.
Right! The study found that although water is essential, it is not what holds the majority of fluids in the body. In the ranking of drinks with the greatest hydrating power, it only appears in fourth place.
Why does milk hydrate more than water?
According to researchers, skimmed milk is the drink that keeps the body hydrated for the longest. The reason lies in its nutritional composition, which combines lactose, proteins and sodium, three elements that help the body retain water longer.
These substances function as a sort of “natural sponge”, which retains liquids within the body and delays their elimination through urine, ensuring longer-lasting hydration. Furthermore, milk contains important nutrients such as calcium, phosphorus and B vitamins, which contribute to metabolic balance and the functioning of muscles and nerves.
The ranking of the most hydrating drinks
The Scottish study evaluated several popular drinks and ranked those that keep the body hydrated the longest. The result was surprising:
- Skimmed milk;
- Oral rehydration solution (homemade serum);
- Natural orange juice (unsweetened);
- Natural water;
- Soft drinks (in moderation);
- Iced black tea;
- Hot black tea;
- Sports drinks;
- Sparkling water;
- Beer
The runner-up, Oral Rehydration Solution, is the same simple recipe used to treat dehydration: a mixture of water, salt, and sugar. The sodium present in this combination helps retain fluids and reduce urine production, which explains its high efficiency. Natural orange juice, in third place, stands out for its balance between water, vitamins and minerals, especially potassium, which is essential for water balance.
Water is still essential
Although skim milk came first, scientists point out that no beverage replaces water. It remains the healthiest and most essential liquid for the functioning of the human body, participating in processes such as digestion, nutrient absorption, regulation of body temperature and blood circulation.
Although milk can be a good option to vary hydration, especially after physical activity or periods of intense heat, the recommendation is not to give up water on a daily basis. The ideal is to consciously vary your consumption, favoring natural options and maintaining the habit of drinking water regularly, the simple gesture that continues to be the basis of well-being.
