Hemp seeds produce more oil and protein than any other plant per land area cultivated. Hemp protein and oil are rich in the essential fatty acids (EFAs) that our brain and cardiovascular system need, Omega 3 & 6, in the perfect ratio for optimal human health. Hemp protein has all 8 amino acids, again, in just the right balance to meet humans' nutritional needs.
Per acre, according to a study published in the Notre Dame University journal, The American Midland Naturalist, wild hemp here in the USA produces 8,500 pounds of seed per acre. The study is called: An Ecological Study of Naturalized Hemp (Cannabis sativa L.) in East-Central Illinois, by Alan Haney and Benjamin B. Kutscheid at the University of Indiana at Urbana, Department of Biology.
