Hey Sheila

I was once on a seafood diet...the kind where you eat everything you see.  Bah-dum-bum.  I know...I won't quit my day job. 

But seriously I was very intrigued by your question and the first thing that ran through my head was...I wonder why she is asking this.  Has she heard something?  What is up with seafood and MS?

When I looked at the literature it seems that more than one reference has made a connection between seafood and MS, and some are making some rather extravagent claims.

I found one site where a lady is claiming that seafood is "curing" her MS.  I am a natural skeptic so I am quite hesitant to believe that anything, natural or medical can cure Multiple Sclerosis at this point in time.  I think it is too easy to attribute remissions to whatever we are doing at the time. 

Yet let's not throw the baby out with the bathwater.  Perhaps there is some merit in eating certain types of seafood to promote overall good health.  My bias actually is towards using natural ways to up the ante for good health and food is the easiest source to look at.

You always have to look at the source of any claim however.  Here is a statement made by a fishery.  "There are also a few studies that link fish- and other seafood consumption to a positive effect on other health problems. NIFES carry out research into the importance of the total effect of eating seafood with respect to the development of diseases such as, diabetes, obesity, multiple sclerosis and osteoporosis."

Of course they want more positive research in this area as they want you to buy more fish!

Likewise the  National Oceanic and Atmospheric Administration   makes this claim:

"Other health problems that may be controlled or alleviated by the consumption of omega-3 fatty acids from fish are asthma, arthritis, diabetes, multiple sclerosis, hypertension, migraine headaches, cancer, and some kidney diseases."

I always like to look at independent and objective research and suggestions such as what is given as advice for people who have MS from the University of Maryland Medical Center who tell us: "Omega-3 fatty acids, such as fish oil, 1 - 2 capsules or 1 tbsp. of oil one to two times a day, to help decrease inflammation and improve immunity. Cold-water fish, such as salmon or halibut, are good sources." 

So you just may have something here. 

It certainly wouldn't hurt to eat more cold water fish unless of course you are allergic to it.  It is an easy way to help your overall health. 

One of the reasons I do love to answer these questions is that I always learn something new myself and today is no exception. 

Thank you for your question!
