I know fish is very healthy, providing essential nutrients and most important, omega 3 fatty acids. If you like it, you will enjoy all the health benefits that fish provide. But, some people just don't like the taste of fish and I happen to be one of them.
I was a picky eater as a kid. Not only did I not care for fish, I also didn't like sausage, bacon, etc... That's probably why I loved junk food so much. My mom did cook a lot of chicken, beef and turkey so I did get enough protein! There were a lot of foods I loved, Italian being my favorite and still is! I grew to love healthier foods, mostly on the vegetable side but still do not have much liking to seafood.
