Thanks 1984 and Psych!
A quick internet search turns up this page http://www.4waynutritionals.com/docs/Egg%20White%20Protein%20Functional%20Food%20Blend.pdf
[Hemp protein] is different from other protein powders in its completeness not only with vital fats but also in the fact that it contains antioxidants, vitamins, minerals, fiber, chlorophyll and it is free of lectins, like gluten, that cause inflammation.
But then I found this site which says:
The is a lectin in marijuana (3) which, although not blood type specific, does bond to glucose, perhaps the most abundant sugar in the body. Another species of hemp have been shown to contain lectins capable of binding to galactose and fucose, raising questions about suitability in blood group O and B. (4)
Somewhat contradictory information here. Unfortunately, the second quote is from a page quoting a source and the footnotes aren't included on the page. I haven't been able to locate the original source.
Then I find out that a lot of the pages that are referring to lectins in hemp may actually be referring to Sunn Hemp (
C. juncea) which is actually a type of legume, as opposed to hemp (
C. sativa). These two plants are unrelated, as far as I can tell. There's quite a bit of information out there on the lectin content of Sunn hemp, but next to nothing on actual hemp (other than the sources above). The information I've been able to find is a bit of a mess. This may need to be tested by everyone individually to see if they're having any sort of reaction.
I think that hemp sounds like a good way to go for me since I know that peas (split pea soup at any rate) give me bad heartburn so I was a little iffy about trying the pea protein. I've taken hemp protein in the past without any bad reactions. I'm also blood type A, so even if the second quote is correct, I may be OK with it.
As for pea versus rice lectins, from this site (http://www.owenfoundation.com/Health_Science/Lectins_in_Foods.html) originally posted by Laura in the Brown Rice For Better Health thread (http://www.cassiopaea.org/forum/index.php?topic=15396.msg129000#msg129000) - peas are shown with three "+" for all blood types, which I believe means it is very agglutinating whereas rice shows only one "+" for all blood types, which seems to mean somewhat agglutinating. From this page, between the two, it would seem rice protein is the safest bet, but you're still going to get some agglutination in sensitive people.
