Phula ndi chikonga mu fodya ndi mankhwala omwe angayambitse mawanga achikasu pamwamba pa mano, mwa anthu omwe amasuta kapena kutafuna.

Monga lamulo, chakudya kapena zakumwa zilizonse zomwe zingaipitse zovala zimathanso kudetsa mano anu. Chifukwa chake, ndichifukwa chake zakudya ndi zakumwa zakuda, kuphatikiza vinyo wofiira, kola, chokoleti, ndi sosi zakuda - monga msuzi wa soya, viniga wosasa, msuzi wa spaghetti ndi curry - zimatha kutulutsa mano.
