Crossbro, I didn't interpret your ideas as a hijack. You provided your opinion of inexpensive foods.
I have a family member who developed serious health issues about 14 years ago. It was either change the diet or suffer, with an inevitable operation within a year or two. So the family all changed to basic foods i.e., homemade everything, nothing processed. Grass fed meat. Pasteured eggs. Raw milk when possible. Fruits / veg from local farmers markets, you get the point. It was a pragmatic decision at the time.
Since then, our health flourished. No exaggeration at all. I still love a good pizza on occasion, and I used to love ramen noodles, and other convenience foods. But my body adjusted to "pure" food and now I can't tolerate processed. Overall we have so much energy and we've not been sick a day in years. I thank God for His help those many years ago.
There is a direct connection between the food we eat and the diseases we contract.
