How do I discern between processed/unprocessed food? If I go buy a tin of tuna for lunch - that is processed food isn't it? What is the rule of thumb here
How accurate is http://www.clovegarden.com/diet/paleo.html ?
The link to clovegarden is a pretty good big picture synopsis of Paleo eating as practiced by many on these boards. Many will quibble over some aspects but the main thrust is correct.
If what you are eating resembles the pre packaged item, it should probably be considered unprocessed...if there are no additives. Tuna in a can is unprocessed even though the tuna had to be processed to get it into the can to get it to you in a state unspoiled. Just watch out for tuna in a can packed with soybean oil...which is not a real food. Packed in water or olive oil is better.
Just use your intuition and read labels for additives. If you can't pronounce them or don't know what an ingredient is...be careful.
I allow salt, seaweed, tubers and some dairy. Processed food isn't a helpful category. I like to think in terms of food that is nurturing and food that isn't. Coconut milk is a processed food but it is healthy and nurturing so I allow it.
1) Look at the ingredients on the package. 2) Is there more than 1 ingredient? 3) If yes, then processed.
You could make exceptions for fish in water or something. That being said, it's probably better to skip the BPA-lined cans and mercury and just cook up some salmon or some other kind of fresh/frozen fish and transport it in a glass container.
