My son-in-law, who is very fit, and eats about as good a SAD diet as possible, has some fibrosis matter which blocks his vena cava, causing his legs to swell, etc. It's uncomfortable, casuse him to have to put his legs up several times a day, etc. I read in a Zavastas book that RAW can help with "fibrous matter." It's only logical, of course, and I suspect that it is meat which is the culprit here. Who amon gyou knows soemthign aobut this issue??
