What makes an oyster a quality oyster?

Answered on August 19, 2014
Created March 22, 2012 at 11:24 AM

We know grass-fed beef is better than grain-fed, wild fish is better than farmed fish, ... But I personally know nothing at all about shellfish? How do you know if oysters are high-quality or not? The only ones I can get online are the ones on iHerb.

I'm asking this because I took zinc for a long while, and the supplement was a bit harsh on the stomach. It improved my sleep, but that's all. Oysters seem to be superfood just like liver, and I'd like to replace some of my pills with food one by one. This would replace zinc and cod liver oil already.

You're right btw the white spots = zinc deficiency.

Well I found some at the supermarket (I was out of Crown Prince cans), but they are extremely expensive. It was very cool to eat them though : I had to punch the shells like crazy because they wouldn't open, took me half an hour to open 4 oysters. That joke cost me like 30 dollars for 12 oysters, but I felt like a rich guy eating them, and my temperature was higher than normal which is great.

Oh but you have perfect skin, right? I got used to the texture of liver :), and eat a bit every day now.

None so far, but its only been a couple of weeks. If I could bring myself to eat liver, I would be all set in the superfoods department.

Jjtitus - Blue Ice say their fermented CLO contains quinones. But I think that, again, vitamins in quinone form are slightly different/may be absorbed differently (especially vitamin K2 specifically). So I think vit K2 supplements are still in order.

I don't think CLO contains a pure form of vitamin E, but it contains quinones, which include members of the vitamins K and E and coenzyme Q families (here's more on quinones, but it involves a lot of mindboggling chemistry :http://www.chem.qmul.ac.uk/iupac/misc/quinone.html) vitamin e quinone, for example, has, similarly to pure vitamin e, powerful anticoagulant properties and is said to help with heart diseases :-)

Korion I have been eating that brand for a few weeks now cause of Danny Roddy. 2 cans a week. My advice is to eat them one by one. I had a whole mouth full and there was a bit of sand... (There seems to always be one that has a tiny bit of sand). In anycase, the whole mouth full had to go, and I almost threw up. YUCK!

@Milla, I'd be interested to know more about the FCLO as well... I thought the quinones were only in the fermented skate liver oil (FSLO)? That's why I generally take Vit K2 with my FCLO.

Wow! Your answer are just amazing, Milla. I might go to the coast during the easter holidays, and get some in oostende. Btw, you say cod liver oil has vitamin E, coQ enzymes and vitamin K. Are you sure about that? I always though cod liver oil = retinol + omega-3 + D2 (or D3, I'm not sure)...

They look great if they're BPA free! Because they're packed in water, you can strain it and use it as a delicious nectar in fish or oyster stews. I couldn't help but click on the olive-oil packed smoked oysters linked below...that would be worth an order in my opinion! I eat those like candy!

You say you're from Belgium- there is a fish market in Oostende; perhaps you could give them a call or search around if you can get deliveries. I get all my fish from thefishsociety.co.uk, including excellent frozen oysters. They ship to Europe; its quite pricey, but actually economical if you buy in bulk (they have offers on larger quantities) - especially as the fish is frozen.

Isn't white spots on nails a sign of copper deficiency? Oysters have lots of that too :). Anyways, I might take FCLO but I'm not that sure yet. I'm pretty sure the CLO keeps down my libido.

Yes! My skin improved a LOT when I started taking fermented CLO (I also take the butter oil) rather than just regular fish oil.A lot less dry,and hardly any breakouts; my nails became stronger. I also double the dose when I feel like I might get sick, and I think it's helped prevent me developing full-blown colds. Oysters are definitely a 'superfood' in the way things like marrow and liver are. When I went to France for Christmas I ate raw shellfish platters every day, and I felt so good. Glowing skin, great digestion, healthy energy, and no white spots on the nails (sign of zinc deficiency)

Oysters are probably the safest farmed seafood you can eat. Whilst fish are often fed unnatural diets in the form of fish pellets, oysters don't require supplemental feed or chemical use. Since they are filter feeders, they are used to basically keep the water clean and protect it from eutrophication (accumulation of algae, nutrients and hence bacteria in the water), so that also makes them a favourite of those promoting sustainable seafood farming. I think the crown prince oysters are very good quality, they state that their seafood comes from "managed fisheries" and they do not use BPA in their cans. I'd trust a company that seems conscious of health risks of canned foods.

Crown Prince say their oysters are from Korea, so I think that would mean they're the Pacific Oyster variety, which has 222% of your daily value of zinc in 100 grams, and would also provide about 1 gr. omega-3, as well as 0.75 g of EPA and 0.43 g of DHA. So I think that if you regularly eat oysters (about 100 gr every 2 days or so) I think you can safely stop taking your zinc supplement. For variety, perhaps try getting your hands on some raw oysters, or fresh frozen ones (I buy frozen oysters online).

I wouldn't stop taking cod liver oil, though, especially fermented cod liver oil, simply because it contains many more benefits than just omega 3; fermented cod liver oil contains quinone complexes (combinations of vitamins K, E, CoQ enzymes, etc); the fermentation process makes the nutrients more bioavailable - especially vitamin A; it also contains a lot of vitamin D. So I wouldn't stop taking fermented CLO altogether.

Love

Milla

Fresh oysters have a very distinct smell,like clean sea water..they are glossy when raw(they only way to eat them,IMHO).Bad oysters have almost a urine type smell.If you are buying them fresh fresh,like from a seafood market,make sure the shells are tightly closed, and ask where they came from.Frozen raw,again,make sure the shells are closed.Check for signs of algae,moss or fungus.Be wary of raw shucked oysters,as you have to go by smell alone on those, and always check manufacture date/place of origin. If this seems like a lot,I live on the coast where you can go pull them out of the marsh.Little picky about my shellfish :)

If you are getting fresh oysters, you want to make sure the shells are unbroken and tightly closed (cannot pry them apart with your fingers). If there are open shells, they should close promptly after tapping. They should be stored on ice, and no older than 4 days from harvesting for optimum quality. You can store them in the fridge once you get home, in a bowl covered in a damp tea towel. I would keep them in there for a maximum of 2 days before eating. If you store them in a tight container, they will die. If you are shucking them, they are easier to open if you chill them in the freezer for 1 hr +.

If you are collecting them yourself, discuss with the local fisherman about red tide, just to make sure there isn't any (some places have signs up year round warning of red tide, so it's not all that useful in the end).

Alternative to fresh oysters: smoked, frozen, and canned. Smoked are so delicious, most local fish shops will have some smoked oysters around, either fresh or frozen, or you can request some and they're usually happy to bring them in. Frozen oysters are pretty great, you can usually get them from fish shops for a really good deal (it's easier for them to store in the freezer than to keep them fresh and sell them in the time window). Canned oysters are a great alternative, look for a BPA free can. I love canned smoked oysters, occasionally get a strong craving for them and just eat them whole! Also great flavour to be added to spreads and put on veggies.

My boyfriend used to part-own an oyster farm, and we had an unlimited supply. Look around for recipes, and you'll find it does not really ever get boring- oyster stew, barbequed oysters, raw oysters, smoked oysters...so good!

Korion, where are you located? I know there are several "prime" spots, where you can get amazing oysters for fairly cheap. I used to live in Tallahassee, FL, and we would get oysters from the Apalachicola that were FRESH and CHEAP! We'd buy them by the bushel! My local seafood market here in DE offers them as well, and I've seen many customers getting them. I haven't yet gotten them, since I haven't really had the time for a proper oyster-shuckin' party.
