I live in the Bolivian Andes and have met several people who produce and export quinoa. Even if local farmer meals have never had many diverse ingredients, they usually fare well without consuming quinoa. Given the commercial limitations derived from political actions in recent years the benefits of this whole quinoa craze for local farmers far outweight the costs. It is regarded as one of the best economic opportunities in a country still dependent on natural resources where most of its population work informally in trade-related activities. So stop worrying and go buy more quinoa.
