I was surprised to learn recently that meat alternatives are classified as "ultra-processed" foods (dairy milk substitutes are also classified as ultra-processed as well).

From: What is ultra-processed food? https://www.bbc.co.uk/food/articles/what_is_ultra-processed_...

> Ultra-processed foods usually contain ingredients that you wouldn’t add when cooking homemade food. You may not recognise the names of these ingredients as many will be chemicals, colourings, sweeteners and preservatives.

> More surprising to some will be...“other ultra-processed foods”. This includes baked beans, tinned soups, meat alternatives, soy and drinks used as dairy milk substitutes.

> It can be tricky to identify food that has been ultra-processed because in some cases the same type of food could be minimally processed, processed or ultra-processed, depending on how it’s been made. For example: Bread made from wheat flour, water, salt and yeast is processed, but add emulsifiers or colourings and it becomes ultra-processed.
