You mean taste, one of the sense that makes us what we are today? The thing that humanity and other animals have used to analyze what they feed themselves with?

I'm not talking about eating for pleasure, but you can definitely taste that something is wrong with industrially grown veggies and fruits (and the same apply for animal farming).

Food pleasure from taste is one of the most basic pleasure and so available to everybody and essential for your well being. The fact that immigrants continue to cook like where they are from for most of their life is a rebuttal to your statement. Food quality is of global importance, most problem with food production comes from disorganization and incentives or lack of it not from lack of production.

He's talking about the raw ingredients not some hyper processed supermarket food. If there is something wrong with the raw ingredients I think it is fair that we try to figure it out.
