The other thing I avoid is fat on beef or in dairy. I've been told most of the antibiotics settle in it.
I live on what's now sometimes called "pure foods". It's getting easier to do so, as more people are watching what they eat, more mainstream foods are okay.
A majority of antibiotics are fat-soluble, so yes, any type of animal fat is going to be the storage locker for whatever the animal ate or was fed before slaughter.
I don’t do sweeteners at all. I am lucky to not have a sweet tooth, and I generally avoid any sweet foods except for an occasional peach or prune.
I’m an adherent to the Paleo Diet in general. While I disagree with their addition of certain high-sugar fruits, I find that a healthy mixture of Paleo, keto/Atkins, and non-soy has provided the most favorable results for my health.
