The China Study by Collin Powell
In Defense of Food by Michael Pollan
Nourishing Traditions by Sally Fallon (This has some great information and a lot of recipes)
I think these are some fabulous starters to understand our food better. As with any information found in the world, you will have to do some sifting here. I don't agree with everything these authors say, but what they do say that agrees with and supports the Word of Wisdom and the modern prophets is fabulous and motivating.
For instance, Sally Fallon thinks that animal products are really important for our health. Collin Powell's research shows that eating meat sparingly or not at all happens to be really good for our health, even to the reversing of cancer! Which one do I agree with? That's easy. But Sally has a lot to offer as far as the proper use of grains, and how to use time-tested techniques to preserve and sprout foods for our greatest benefit. I really like a lot of the other information she has too. There is a lot of good to be found, and we are blessed with brains, experimentation and discernment to figure them out for ourselves and for our loved ones.
Knowledge is power, as they say. And it's exciting. I never thought I'd enjoy researching something so much.
Dig in and enjoy!
