foods like avacado actually have something in them that fight cancerous cells so kind of like damage control. it's like drinking too much alcohol so preventing a hangover by drinking water between drinks & taking an anvil b4 sleep with glass of water.
I believe on occasion, nothing can do that much damage. There are things you can eat that also conquer any bacteria etc in your body. so If you want to treat yourself, then do damage control by eating avacado or something super healthy.
