text: red onions and canned salmon? hello, i am a big fan of red onions and canned wild salmon (no mercury)..is it safe to have canned salmon over fresh salmon as long as its mercury free? is it just as healthy to have canned salmon as to fresh salmon?  what do red onions do for your health? i know they are are part of the garlic family..but are red onions healthier than the other color onions?  thanks and if canned salmon, fresh salmon & red onions are not dead... they will live happily in you stomach ever after..
