Drink 8 glasses of water every day.
That’s such BS. Your body tells you when you need to drink with this thing called thirst. And is a longer life spent mostly urinating really worth the effort?
Total junk science, but because it’s a round number and emotionally appealing, some people have glommed onto it as a health benefit.
Back when I was overweight and eating mostly processed, salty foods, I needed a lot of water. Since switching to mostly whole foods (lots of fruits and vegetables), the only drink I have is a cup of coffee in the morning and maybe a glass or two of wine or beer at night.
