"One common belief is drinking lots of water is the best cure for dehydration. While water intake is indeed very important for the kidneys, drinking too much may be as bad as drinking too little if the body cannot hold onto what is consumed. Chinese dietary therapy suggests that the best way to consume liquids is by eating soup because the bones and root vegetables all contain minerals that help the body hold onto water. Soup was considered one of the best medicines and is still a popular and proven remedy when someone is ill.

Recent new research shows that consuming grains that absorb large quantities of water like oatmeal are also very hydrating."
