Granada: Beer is better at hydrating the body after exercise than just water, according to new research from Granada University in Spain.

The scientists believe that the sugars, salts and carbon dioxide may be responsible.

The study looked at 25 students over a period of several months. They were asked to run on a treadmill in temperatures of 40C (104F).

Once they were on the point of giving up, researchers measured their hydration levels, concentrationability and motor skills. Half were then given two half pints of Spanish lager to drink, while the rest were given water. Both groups were then allowed to drink as much water as they wanted. The rehydration effect in the students who were given beer was ‘slightly better’ than among those given only water.

Based on the studies, the researchers have recommended moderate consumption of beer – 500ml a day for men or 250ml for women – as part of an athlete’s diet.

The ingredients of beer – which include malted barley, hops and yeast – are rich sources of vitamins and minerals.
