After reading this post and its references, I take away the following,
These are my express paraphrases, and you should read the entire posting for yourself,
- Avoid "Ultraprocessed products" (yes this is a real term) These products resemble food but are most likely contain only modified fats and sugars but contain representations of actual food as a market point. Dr. Ludwig uses a brand of fruit snacks. You have been forewarned, read the labels, "contains real fruit flavor" does not mean actual fruit is an ingredient.
- Ultraprocessed products come from extreme chemical and mechanical manipulation of just 3 species—corn, wheat, and soy. In other words you could have a hamburger on your plate, (the cow was fed corn, not grass), the bun (modified wheat, soy, and/ or corn), the ketchup (corn/soy derived sugars), the cheese (either includes soy as an emulsifier or the dairy cow was again fed corn, not grass).
