Comparing the two labels I have, I would say yes. You wouldn't get the omega 3's with chicken but you can get these else where (flax seed)
For me canned/pouch chicken will always win, I have tried for years to force canned/pouched tune down but I can't do it. Just do not like the taste.
Edit: the labels I have are on the pouched chicken and tune. sodium level wasn't to bad no great but not to bad. The chicken has less sodium than the tuna (the brands I have).
