How to find healthy food

One of the things that I've been trying to do the last few years is figure out this whole "food" thing and what it means to eat healthy (without sacrificing taste). Yet I still find it confusing. There's a whole lot of meaningless health claims attached to food, and I know that Michael Pollan's advice is to avoid any food that makes health claims if you're looking for healthy grub.

Walmart tends to get portrayed as ruining the planet and the economy - and I think that there's some truth to that - but on the other hand, Walmart apparently sources more produce locally than most grocery stores and in blind taste tests foodies found that they preferred the taste of the Walmart stuff to their normal organic fare.

Then there's the whole issue of animal welfare and sustainability. Buying "free run" eggs was declared by Food, Inc. to be relatively meaningless as there are no defined standards for such. Some people seem to eat kosher or halal meat even if they're neither Jewish nor Muslim as they think that the animals are better treated but, generally speaking, that doesn't seem to be the case. And, of course, on the sustainability side, sustainable seafood labels appear to mean little.

What to do about it? For now I guess the answer is to just eat something and to try to avoid the uber-processed stuff.
