Research published in the International Journal of Sport Nutrition and Exercise Metabolism has shown that drinking low or non-alcohol beer is a good way of rehydrating after exercise.
Many athletes are likely to engage in the consumption of beer following exercise regardless of the negative health implications.
However, the research shows that low alcohol beer with added sodium may provide a compromise to the hypohydrated athlete following exercise in that it is a beverage with high social acceptance but avoids the exacerbated fluid losses observed when consuming full strength beer.
The emphasis of beverages with lower alcohol contents may also act as a useful harm minimisation strategy aimed at the recovering athlete.
In summary, a reduced alcohol beer with added sodium will reduce post-exercise fluid losses compared with full strength commercial beer.
