I think the question of how low you go really depends on what's in the shopping basket. That's a large part of it.
This morning people got up and had a glass of milk, and maybe on the way to work they stopped off at a very large national chain doughnut store. Well, gee whiz, there was no trans fat, or very little.
When we say “no trans”, that's a misnomer. There is trans in no trans. Certainly in the case of California and New York, there is trans fat, absolutely. You do not have a no-trans product. Milk has trans fat. Steak has trans fat. A well-processed, extraordinarily healthy IP canola oil has trans in it. Trans fat is caused by heat.
