I've added two things to my diet today: Canned smoked mussels and
smoked oysters.
Reading the labels:
Mussels: 1 can (65g) with cottonseed oil has 110 calories and gives
you 50% of your daily of iron.
I read that this is not a healty oil. I don't know if the 110 calories
include the calories of the oil.
Oysters: 1 can (65g) with vegetable oil (does not specify which
one...) has 120 calories and gives you 90% of your daily need of iron.
