Shocked, I am!
"even five a day can hammer the liver."
Damn.. I guess it's back to only four a day for me.
Seriously, who would ever say "only five" or "just five" a day is healthy? I used to drink 2x 330ml cans of Coke or Pepsi a day for a long, long time but I always understood that the sugar and acids in the drinks was bad for me. I have perhaps 1 - 2x 500ml bottles a week now and mostly drink a lot more water or diluted juice. I don't drink tea or coffee*.
*I know how weird that must be for so many to see.
