I was under the impression that Japanese did consume animals? I remember reading that the Buddhist were not allowed to eat other animals, but fish was viewed as ‘ok’. I remember reading in a few books that some Japanese started consuming more animals around the 15th century. I believe around the time when they were introduced to the Western style of eating.
I think the article is referring to isolates since it states ‘meat & milk’ some of your ‘soy meats’ do use isolates. I think ‘Gimme Lean’ and ‘Boca Burger’ contain soy isolates. Some of the soymilks might as well. The occasions I do consume ‘soy milk’ or make the occasional ‘soy meat’ for family/friends. I will make it myself.
