Health Freak

3 more days and I start the Clean program.

I highly suggest reading the book Clean by Alejandro Junger. Definitely life changing. Or lifestyle changing at least. In just the first few chapters I learned so much about how the body works and how different foods affect the body.  There's a list of foods you can and can't eat on the Clean diet.  Some of the ones you can't are tomatoes, oranges, strawberries, soy products, gluten, dairy, eggs, and a bunch of other things.  The whole idea of the program is to detox the body while restoring it to natural health. Basically returns you to the state you were made to be in. It's 3 weeks long (with some prep time) and includes some recipes in the back of the book while is extremely helpful because it requires replacing breakfast and dinner with liquid meals.  When food is in liquid form it takes less energy to digest so the body can you more energy for detox and restoration. It also eliminates common allergens (i.e. strawberries, chocolate, gluten, and soy) because when eaten (especially if you are allergic) they cause the body to go into attack mode, preventing it from getting any nutrients or digesting because it's spending its energy on destroying whatever you just consumed.
The main focus is detox though.  Toxins are in so many things we consume/breathe and damage the villi and microvilli in our intestines, preventing us from getting the nutrients we need.  By removing the toxins, the villi are restored, etc. We get healthy.
