<<Disclaimer: Verify this information before applying it to your situation.>> Hi. My son was tested with high levels of lead and alumnium. I have worried about buying the rice flour and bean flour from asia and india. Now I am very worried. Has anyone else deal with this problem? I am thinking about getting a mill and grinding our own brown rice. We are three celiacs strong so this will be alot of work. Any thoughts? Elyse, a silly yak in columbus, ohio
