Hello I'm 18 years old and I have Myasthenia Gravis since I was 14/15 and I'm here to say that I been trying the raw vegan diet and I feel WONDERFUL just PERFECT. I highly recommend this diet for your husband. But what I eat is mostly fruit, some greens and a few raw nuts here and there. I make a green smoothie for breakfast, lunch is a bowl of fruit(as much as I like) and then a few nuts and dinner is another green smoothie. I'm feeling great and full of energy :)
