Hi Charlotte, a lot of forum members have found that when they eliminate nuts completely that they do in fact get an adverse reaction from them. I think almonds in particular do have high concentration of anti-nutrients in them. These products usually have a high amount of sugar in them as well, unless you are making your own.
Since this is an older thread I also wanted to note that rice milk and rice in general has also been found to have proto-glutens (I think that is the correct terminology) in them. It's a lessor amount than some other grains, but the amount usually doesn't matter so much when your body recognizes how sensitive it is to gluten.
