No more then either 1 cup of caffeinated coffee or soda a day. I avoid unhealthy foods
, sticking to a pretty good diet
. Even snacks now are things like Edamame or dried fruit, nuts, popcorn, things like that.
I have not gone so far as to let grey come in, but my hairdresser does use foils only now, so it doesn't get on my scalp. I don't worry at all about facial cleansers, makeup, nailpolish or anything like that.
A big one for me has been a lot of the household cleansers.
