abstract
The purpose of this study was to investigate if quinoa (Chenopodium quinoa Willd.), a good source of nutrients, fibre, and phytochemicals, can modulate risk disease biomarkers on obese-diabetic (db/db) mice. The db/db mice fed quinoa-supplemented (quinoa) or AIN-93G diet (obese) were compared to lean control fed AIN-93G diet. Quinoa intake reduced at significant level plasma total-cholesterol (total-c), LDL-c, and oxidized-LDL to levels similar to lean; lessened protein carbonyls and interleukin (IL)-6. The hepatic steatosis and total-c accumulation in liver were also similar between lean and quinoa and lower than obese. Quinoa fibre and phytochemicals may have contributed to these health benefits. However, quinoa intake increased plasma insulin and did not protect from other pathophysiological manifestations of the db/db research model. More studies are needed with other research models and quinoa doses achievable by human diet to validate the clinical relevance of this study.
