Abstract: Background: A healthy diet and weight management are beneficial in reducing risk factors for type 2 diabetes. Increasing dietary fiber intake has been shown to lower post-prandial glucose (PPG) levels and increase satiety, but the majority of people do not meet the recommended fiber intake. Chia seed (Salvia Hispanica, L) contains an excellent source of dietary fiber and has been shown to be positively associated with lower PPG levels and decreased appetite. \nObjective: The proposed study was to determine the effect of supplementing 20% of daily calories from chia seeds on satiety and PPG levels. \nDesign: This was a free-living, randomized cross-over design study with 5-week treatment periods separated by a 5-week washout period. Twenty-three healthy females, between the age of 19-50 years and with a normal BMI from Cal Poly Pomona were recruited. Fasting glucose and PPG levels were measured using finger prick testing at baseline and 60 minutes after consuming 1/3 of the allotted chia seed in 6 ounces of 100% fruit juice. Satiety was measured by satiety rankings and visual analog scale (VAS) appetite questionnaires. Postprandial glucose levels were analyzed using a 2(condition) x 3(time) repeated measure ANOVA. Satiety was analyzed using one-way ANOVA and independent t- test was used for VAS appetite questionnaires. \nResult: The before, during and after meal satiety, VAS appetite questionnaires and PPG levels were not significantly different between the control and chia seed supplemented period. \nConclusion: Twenty percent chia seed supplementation was not associated with lowering PPG levels or increased satiety in this study.
