I have the same two beliefs and another one: 3) Everything in moderation.

All the things that we belief to "know" today could once again be proven wrong tomorrow. Just because someone claims that butter, coconut oil, bacon or almond meal is healthy, that doesn't mean you have to go crazy with it and eat large amounts of it daily. Or the other way around: just because some people think that dairy or grains are harmful, for a lot of people it may not be an issue at all to eat them every once in a while (at least if someone is able to e.g. eat only one slice of sourdough bread and then not go carb crazy; I'm not).

I just think given the fact how often we've been wrong in the past, it is smarter to decrease risks by not overusing any kind of food group.
