Well, it's the drawback of the American neolithic peoples that the only cereal they had is corn/maize. Leading to pellagra and to generall cell energy supply problems. Near east/Europe/Asian cultures are more lucky as the species cultivated there show a better niacin availability plus a higher tryptophan content. In addition they found sesame, which is extremely high in tryptophan content. Niacin iss an issue only for traditional american people. Amadeus S.
