In Ecuador the incidence of obesity, diabetes and other chronic health conditions -- which are partly due to changes in dietary behavior -- has been increasing, often most dramatically in smaller urban centers. The ubiquitous consumption of white rice is likely one important factor in this nutritional transition, while the consumption of traditional healthy foods such as quinoa remains generally low. In a 2013 survey we conducted, 67% of the 240 residents surveyed in the small Andean city of Riobamba reported they would prefer eating quinoa “rice” at least twice weekly instead of white rice. With the objective of encouraging more normative household consumption of quinoa in this population, in late 2015 an intervention was begun to promote consumption of quinoa rice 3 times a week among 131 adults in Riobamba. Between the baseline and the termination of the intervention four months later, no significant change in BMI was observed. However, at 2, 4 and 7 months’ post-baseline, 52%, 40% and 47% of respondents, respectively, reported enjoying consumption of quinoa rice instead of white rice either “very much” or “in general,” and 64%, 55% and 68% of respondents “definitely” or “very likely” planned to continue doing so. Our findings suggest a modest acceptance of this (re)introduction of a traditional and healthy food, though further and more extensive research could assess with greater precision the potential health impacts of such reported changes in dietary habits.
