Barley grass juice is extremely high in vitamin A and chlorophyll. I've noticed that eating a lot of steamed, leafy, dark green vegies -- also high in vitamin A and chlorophyll -- makes my symptoms abate very significantly. In fact, leafy greens and salmon seem to be the two types of food that have a direct effect on my symptoms. I'm guessing the salmon is beneficial because 1. it's also high in vitamin A, 2. it's very high in B vitamins, which are nutrients for the central nervous system, and 3. the omega-3 fatty acids in salmon are anti-inflammatory, which might help keep inflammatory compounds generated by the tumor from irritating cranial nerves that control balance, hearing, etc. The exact mechanisms for why these foods help my symptoms is conjecture on my part; all I know is, the positive effects I feel are very real, very consistent and more than subtle over the long term (adhering to the diet). Hopefully, this will help you, too, S. arah.
Best wishes,
