Looking into nutrition you can often stumble across the odd new fact..well here's a quick fact about buckwheat. Buckwheat is 18% protein, which isn't so shocking, but the biological value is over 90% (high fibre & tannin levels may lower that to the 80's or slightly lower), this is due to the all essential amino acids, especially lysine, threonine, tryptophan, and the sulphur-containing amino acids.
Buckwheat isn't a grain it's a flowering plant & so doesn't have some of the allergy issues of other grains & isn't related to wheat (silly name then, I know):
I hadn't really thought about buckwheat as a food in my diet really, nor in anyone elses (except those that couldn't have wheat), now I might have to think about it. I believe that Infinity foods (a big health food store in my town) sells stuff like fresh baked buckwheat loaves & stuff, so I might have to experiment a bit & give buckwheat stuff a go as I seem to have missed this crop out of my diet for no good reason.
Here's some links to some stuff about buckwheat if you fancy a read:

In case you're wondering I'm reading the book : Whole Grains and Health Edited by Len Marquart, David R. Jacobs, Jr., Graeme H. McIntosh, Kaisa Poutanen, Marla Reicks hence you might be getting the odd 'grain fact' over the next few days
