These aren’t publishing years, just the year these books transformed me.

The paleo diet is awesome. I've lost a considerable amount of weight on it, and feel and look much better.

Also, a diet with staples like grass-fed beef, pastured butter (or any other healthy animal fat), avocado, and fish is my kind of diet. No more forcing down bitter grain or soy products in fruitless attempts to go "healthy". Plus, my meals are so substantial and high in fat that I only need to eat once or twice a day.

For anyone interested, there's a lot of good paleo sites out there, but I'd start with http://paleonu.com and http://freetheanimal.com

And if you can, pick up Nourishing Traditions by Sally Fallon.

In a quest to heal my wife's life-long bouts with Fibromyalgia and other chronic pain disorders, we have had to try a number of things over the years. Food has been our biggest change to date.

We had to switch to buying organic foods because anything artificial sets her body off. Anything with pesticides does it too. This rules out pretty much all conventional produce entirely.

We also had to stop shopping from the center of the food store too. We cut out all the processed stuff and started cooking whole meals. We are extremely picky about what type of meat and dairy products we purchase because of GMO-containing animal feeds (not to mention anti-biotics, other things which are like anti-biotics but not called that; really insidious stuff, growth hormones, bad water, pathogens from neighboring operations, etc).

We started buying only pasture-raised animals and this year I'm learning to hunt since we moved to a place conducive to that activity. We're also getting dairy goats to help offset our $3500+ per year un-pasteurized dairy/cheese/butter costs. I mentioned in another comment that I'm raising 50 chickens for meat and eggs and have already learned to butcher them. They taste AMAZING!

We follow the GAPS Diet and Sally Fallon's Nourishing Traditions cookbook, and also the Weston A Price foundation. We take lots of High-Vitamin Butter Oil and Fermented Cod Liver Oil. We infuse a variety of herbs. We take pharmaceutical grade Pro-biotics when necessary.

There is a shit-ton more to food than just saying "Eat Organic" or not. We have to understand nutrition from an old-world view as well as a new-world understanding and blend the two together. The very soil that the food is grown in and the animals are raised on contains so much life that has a lot to do with how nutritious the food ends up being.

I could go on and on but I'll stop. I will say it's been a huge odyssey for us, on the quest to stop chronic illness. It is definitely working and worth it, however.

Oh, I treat my ADHD this way too.

Yep - I've been following a similar diet (GAPS) to improve some health issues and found that the first few weeks were tough because of sugar/carb withdrawal symptoms but it improved a lot after that.
I'd recommend the book Nourishing Traditions for anyone wanting to keep eating some carbs. It's based on the Specific Carbohydrate Diet which it's my aim to transition to eventually as it's a bit more relaxed about grains/pulses/dairy when prepared correctly.
