RE: Buckwheat
Found this on the web...
"Buckwheat is similar to oats in nutrient composition with a protein content of approximately 12.0 percent, a crude fiber level of 12.8 percent, and a digestible energy level of 1,360 kilocalories per pound. The protein quality of buckwheat is reportedly among the highest in the plant kingdom. Buckwheat has a higher concentration of essential amino acids than other cereal grains (Table 1). Particularly important are the levels of lysine and threonine, the first and second limiting amino acids in most cereal grains. "
I've never tried it but, I'm interested in how it works in the south.
