Effect of 8 weeks of Quinoa supplementation on Irisin serum levels, lipid profile and physical parameters of obese unexercised adult women in Ardabil city

Nutritional supplements prevent diseases by reducing appetite and obesity. The aim of the study was to investigate the effect of eight weeks of Quinoa supplementation on Irisin serum levels, lipid profile and physical parameters of obese unexercised adult women in Ardabil city. The research method was semi-experimental and laboratory with a pre-test and post-test design. The subjects of the research were 20 inactive obese health adult women in Ardabil who were randomly selected and matching in two Quinoa supplement (n=10) and Control (n=10) groups. The supplement group consumed 25 grams of cooked quinoa three times a week for eight weeks. To measure Irisin and fat profile, 5 ml of blood was taken 24 hours before and 48 hours after the last session. Physical indices were also measured. To compare the mean of data between and within groups, before and after eight weeks of quinoa consumption, ANCOVA with Bonferroni post-hoc and paired t-test were used. Significance level of p<0.05 was considered. Serum Irisin level (P=0.0001) of the supplement group increased significantly after eight weeks of quinoa consumption compared to before eight weeks and compared to the control. Meanwhile, serum level of VLDL (P=0.0001), triglyceride (P=0.0001) and total cholesterol (P=0.0001) decreased significantly. Other indices of lipid profile and body composition did not change significantly (P<0.05). 8 weeks of Quinoa supplementation probably stimulates the secretion of Irisin and causes the reduction of VLDL, TG and TC in unexercised obese women.
