Is shellfish really that bad for you?

I've heard that I should only eat regular (salmon, tuna) rather than lobster, shrimp. Anyone have any more info on this?

Salmon is great for you! You have to watch your tuna intake due to higher mercury levels and keep it to two servings per week. I think some shellfish (shrimp) may have higher cholesterol levels but haven't heard that it's just plain bad for you. Shrimp is not high in calories though. Good fish to stick with are salmon, mahi mahi, halibut, cod & tilapia.

shellfish is fine....

Just because a food is high in cholesterol does not mean it will raise your cholesterol. In fact cholesterol is necessary for brain function-it has gotten a bad rap because high levels are linked to (but not necessarily the cause of) heart disease. Shellfish is any sea animal with a shell, including mussels, shrimp. scallops, crab, clams and lobster. They are all good for you, but like any other food, eat in moderation and avoid farmed varieties.

It is the bottom feeder of the ocean though. Everything they eat, you eat. It's not like salmon, or cod or the like. I know many people that have allergies to shellfish and not to the other swimmers.

Here is an easy-to-read table with mercury levels in different fish and shellfish. Shrimp, lobster and scallops are in the "low mercury" category.

Shrimp do contain cholesterol, but much less than eggs, meat and dairy.

Bon appetit!

I learned from my doctor that the reason they'll ask you if you're allergic to shellfish if you go in for many kinds of tests is b/c most shellfish allergies are actually iodine allergies! So I guess they contain a decent amount of iodine??

(I am allergic to iodine, but not to shellfish - found that one out when I had some tests done and was injected with iodine, after telling them that I'm not allergic to shellfish... My reaction wasn't ridiculously severe, but still not fun. So, I guess the levels of iodine in shellfish can't be excessively high...)

Shellfish is different though. There might not be high levels of mercury, but there is a reason that cultures through the generations recommend that you do not eat shellfish. However, they are a wonderful source of protein and I love it.

I have Graves Disease and one of the things I can't eat to much of is shellfish because of the iodine, it does have high levels of iodine and is very low for mercury. A lot of cultures don't eat shellfish, including practicing Jews because shellfish are considered unclean, they are bottom feeders, sort of the same thing as pork. As far as cholesterol goes a lot of it is genetic. I eat all sort of high cholesterol and don't have a problem, in fact no one in my family does. My husband on the other hand eats hardly any high cholesterol and has high cholesterol as well as most of his family.

I'm not sure I understand the concept of bottom feeders in terms of shell fish - they do eat all the stuff at the bottom of the ocean (since that's where they live), but they are also the bottom of the food chain. Why a lot of the bigger fish have so much mercury is that mercury isn't flushed by the body, so the big fish eats the slightly smaller fish, who ate the smaller fish, who at the tiny fish, and the big fish ends up with all those other fishes' mercury in his body, which we get when we eat him.

Shellfish, on the other hand, only eat little tiny plankton or plant matter, which has almost no mercury (and probably very little other bad stuff, too, although this is where my knowledge gets fuzzy), making them, at least in that way, healthier for us to then eat.

Your right, but for some reason they are considered bottom feeders and bottom feeders are considered unclean in many cultures. They sure do taste good though.
