It's too bad the peas are a bother to your system. I love peas. We have been having them so frequently recently, however, that I'm quickly starting to get tired of them. I buy them frozen in those steamer bags. Sometimes they 'strings' aren't removed, and I think that's what I'm tired of - picking strings out of my mouth. *le sigh*
But, a pea is a legume, so maybe that's the trouble you're having... The pod is good for you, but maybe the legumey part of it is taking away from the goodness?
