Sea vegetable high in oxalates NEW
by: Nelson

I have been diagnosed with hyperoxaluria. I get incredibly sick if I eat oxalates. Nori, which is the sea vegetable used in sushi does not make me ill, even if I eat 10 sheets. My kidney's don't hurt at all when I eat it.

Kelp also has never given me any problems, but you can't eat more than about 1 1/2 TBS because it is so rich in iodine. For all I know, it is moderately dense in oxalic acid, but small amounts are insignificant.

I have gotten very sick from attempts at eating other sea vegetables. I believe Irish moss was one of them.

I don't know their specific names, but I was told to avoid eating the feathery red seaweeds as these contain high amounts of oxyalic acid. Sea sorrel was a name given but I wouldn't know the latin name and it could be a common name for several different species. This was in Cornwall, UK
