Fig. 1. Glucose response of 26 subjects to tolerance tests for glucose or three breads. Least-square means±SEM. Within a collection time, glucose values with different superscripts were significantly different. Glucose was significantly affected by treatment (p<0.02), time (p<0.0001) and treatment-by-time interaction (p<0.0001).
Fig. 2. Insulin response of 26 subjects to tolerance tests for glucose or three breads. Least-square means±SEM. Within a collection time, insulin values with different superscripts were significantly different. Insulin was significantly affected by time (p<0.0001) and by treatment-by-time interaction (p<0.001).
Fig. 3. Glucagon response of 26 subjects to tolerance tests for glucose or three breads. Least-square means±SEM. Within a collection time, glucagon values with different superscripts were significantly different. Glucagon was significantly affected by treatment (p<0.005), time (p<0.0001) treatment-by-time interaction (p<0.0001).
Fig. 4. Thyroid stimulating hormone (TSH) response of 26 subjects to tolerance tests for glucose or three breads. Least-square means±SEM. Within a collection time, TSH values with different superscripts were significantly different. TSH was significantly affected by time (p<0.0001) and by gender-by-time interaction (p<0.0002).
