Wish I had time to write a lot about this!!
Cognitively ok, but doesn't matter what you have to do to be there--even if it means you never touch another Twinkie!
A good example of this is me

. I was as sick as my son when we began this journey--major brain fog (I mean, you wouldn't believe!!) and SOOO tired and digestive issues and on and on. I have followed along and pretty much just done what we did with my son. And today, I feel really good, look really good, am very functional (I wasn't before) and can live a normal, pretty high-energy life. AS LONG AS I DON'T EAT A VERY LONG LIST OF FOODS, AND KEEP UP WITH MY SUPPLEMENTS. I suspect my son will be the same.
I've been studying nutrition, and guess what? If you don't do a B12 supplement, and you don't eat liver or greens, then you are probably aren't getting any at all in your diet. Ditto with a long list of vitamins--Americans simply don't eat the stuff we should in the first place, and then commercial farming techniques have done a tremendous amount of damage to the food that we DO eat. And commercial food processing.
I am of the opinion that just about everyone in America should be on supplements, especially B12, from what I read. Reading about the state of nutrition in our country is very scary stuff--and so is the toxicity of our environment. I've turned into one of those environmentalist wackos, I guess!! But my son's autism, and the health of the rest of my family, has really opened my eyes.
