How much albacore canned tuna can a 18 year old male safely eat? i'm 5'9 160-170 pounds. and also, are mini bella mushrooms healthy?

Mercury toxic; NO!!!: Unfortunately tuna is fairly high in mercury. Experts advise eating canned albacore no more than 3 times a month, though it is ok to have "light" or skipjack tuna twice a week (but not both!). See http://www.Nrdc.Org/health/effects/mercury/tuna.Asp portabella mushrooms large and small are healthy but they should be cooked and organic ones are much better to avoid pesticide exposure.
