I don't think the "holier than thou" attitude is really necessary, there's no point in telling people they are eating/enjoying the "wrong" foods or that your tastes are so much more sophisticated than the peons, which is what this post boils down to.
I enjoy "proper" tomatoes and tomato based dishes (especially caprese with good quality ingredients) but I would never eat a tomato like I'd eat an apple. I very much enjoy a really good quality olive oil with bread, but I would never call it a "feast," nor do I consider it a particularly healthy choice. If the nutritional value/fullness were the same, I'd still pick the kitkat over vegetables many days. I think the fake truffle oil is nasty, but I don't go around putting down people who enjoy it, which many do. I also don't drink low quality beer, but I'm not running around putting down people who do.
