Your body doesn’t run well on blood that’s filled with chemicals, preservatives, refined & processed petroleum, and other non-food items.
To a certain degree, your body has the ability to eliminate these toxins naturally. But it can only do so much. If you overload it, those toxins will poison you.
On the other hand, even if you’ve eaten a diet that high in junk for many years, your body can reverse many inflamed &/or toxic conditions by switching to a clean diet after just a matter of a few days!
When I went to nutrition school, they repeated this almost every week: “Given half a chance, the body will heal itself.”
Give your body more than half a chance.
Put food into it. Not other things (which are not food).
