Neither water, nor tea, nor orange juice. The most effective drink to keep the body hydrated in the long run is milk, according to a British study.
Despite being the number 1 choice to quench the headquarters, water does not retain as many liquids in the body as thin or fat milk, according to the American Journal of Clinical Nutrition.
The study was conducted with 72 healthy men who arrived at the Laboratory in a state of normal hydration and fasting. Each participant ingested a liter of one of 13 popular drinks – Including gas without gas and gasified, milk, coffee, juices and sodas. Over four hours, researchers measured urine production to evaluate the amount of liquid retained in the body.
Based on these measurements, scientists have created the Beverag Hydration Index, BHI), similar to the glycemic index, but for drinks. The results showed that, after two hours, the lean It had the highest BHI – it retained about 339 grams of liquid more than water.
According to the study, milk moisturizes better than water due to the presence of lactose, proteins, fat and sodium. These components slow gastric emptying and reduce urine production, keeping liquids in the body longer, recalls the.
Oral Rehydration Solutions They work similarly: they contain small amounts of sugar, sodium and potassium, helping to retain more water in the body.
Other drinks presented mixed results. Orange juice has shown some moisturizing benefit, but the high sugar content can cause an osmotic effect on the intestine, removing water from the body. Soft drinks, with or without sugar, were no more moisturizing than water. Already the Coffee and tea, in moderate doses, were as effective as water.
Finally, the alcohol turned out to be a special case. Beer, because it contains more volume of water, caused less fluid loss than distilled drinks like whiskey.
Authors suggest that BHI may be useful for athletes or professionals in liquid -limited environments.
However, for most people, head the headquarters remains the best orientation.
