This is all demonstrably false and goes against the available evidence.

Here’s a good Lancet study that investigates ultra processed foods by sub-type and looks at the health impact. Those who are meat and sugary drinks with artificial sweeteners had the highest incidences of cancer. Those who ate high amounts of ultra process plant based alternatives had a lower cancer rate than the base population. Believe what you want, but when it comes to cancer, eating ultra processed plant based products is better than meat.
