Eight glasses of water a day 'excessive' according to new study

Yosuke Yamada of Japan’s National Institute of Biomedical Innovation, who co-authored the study, has said that the guidelines are “excessive” and “not supported scientifically at all.”

Many scientists are unsure of where the guidance came from, and noted that it does not take into account the water content of food that humans consume.
