We find that a value of the pion-nucleon sigma term of $\\sim$60 MeV is not necessarily at odds with a small strangeness content of the nucleon, in line with the fulfillment of the OZI rule. Moreover, this value is indeed favored by our next-to-leading order calculation. We compare our results with earlier ones and discuss the con","authors_text":"J. A. Oller, J. M. Alarcon, J.
