The effect of mushroom intake on modulating post‐prandial glycemic response (647.48)

Abstract

The consumption of mushrooms has been shown to lead to a number of health benefits. To determine the effect of Portabella mushroom intake on the glycemic responses of a young, healthy population following an Oral Glucose Tolerance Test (OGTT), 8 men and 8 women (19 to 29 yo, avg = 24;Body Fat % 18.4±7.2; Fasting Glucose 89.2±4.0) completed 3 modified OGTTs over a 2 week period. The OGTTs were evaluated in response to a 75g Glucose Drink (G), a 75g Glucose Drink with 9.5g Portabella powder (MG), or 9.5 g Portabella powder with Stevia/flavored water (M). Fasting and 30 min blood samples were collected for 2 h. Glucose levels were only elevated with G and MG with MG being higher in men at 30 min (P<0.02) and women at 60 (P<0.005) and 120 min (P<0.01). Insulin was higher in G and MG and showed a more gradual decline with MG in women. In women, hunger (Likert Scale) increased by 120 min (P<0.05) during G which was eliminated my addition of mushroom powder. Mushroom powder reduced postprandial hypoglycemia, rapid insulin decrease and elevated hunger in women compared to glucose alone. Mushrooms may moderate postprandial glucose related responses.Grant Funding Source: Supported by Mushroom Council
