not TWA but similar...

I am kind of newly obsessed with this woman and her story about her autistic child:

She is a biochemist and realized that tons of foods that are gluten free still have glutamate in them. Glutamate is processed by your body into MSG...so if you have an MSG sensitivity you need to watch out for these other ingredients. Of course this stuff is not labeled...the video of her going through the store reading labels really got me:

Oh and she mentions that there is a pesticide that they use on conventional crops made of MSG!! And they don't have to label it...so really go organic.

This book also made an impression regarding food and children:

Here is Robyn's TED talk where I first heard about her:
