What is seafood from dietary view?

Hi Happy 2011. I started my topic from today again after several random post and tips which I shared last few weeks. What is actually seafood? We usually only can think out it is source of protein but what else? Fish and shellfish are good sources of essential vitamins, such as niacin, and minerals,
such as selenium (antioxidant) and iodine (treat goitre problem).

 I am going to share some info about fish and shellfish for the next few post after I edit and format some of my information. Stay tune.
