Os processos mais comuns sao: deixar de molho em meio acido, germina-los e cozinha-los. As vagens nao apresentam esses inconvenientes e sao uma otima opcao.Estudos citados:1 Katz, Solomon H., Food and Biocultural Evolution: A Model for the Investigation of Modern Nutritional Problems, Nutritional Anthropology, Alan R.
