The way I started this journey was to think about food in the traditional sense. Food was raised and grown and then cooked at home using old world recipes. You can start that way. Above you talked about some wonderful traditional foods that you are making in your own kitchen, then you talked about a factory produced junk food. Keep the traditional foods and dump the factory food. Take a few simple steps that don't require any deprivation, just a change in ingredients.
1. no seed oil
2. shop for ingredients not products
3. dump sugary drinks
4. drop as much sugar as you can.
5. stop eating sandwiches, a Dagwood in a bowl is just as good
6. eat grass-fed meat
7. don't be afraid of eggs
8. don't be afraid of fat, butter is good. Add it to whatever starchy foods you eat, that's what our ancestors did.
after you do this for a while and you learn more here, you will stop the poisons and won't miss them a bit. The we hope you experiment and share your recipes with us because we love to cook and eat too.
It's grandma, but you can call me sir.
