Figure 4: Fasting and postprandial insulin responses to the ingestion of a consistent amount of the test breads. Test bread was ingested after collection of fasting blood sample at time point −15 min. Data are means. Standard errors are not included for clarity, 𝑛 = 1 1 . Significant overall treatment effects were found in insulin response to the breads (sprouted-grain bread was lower than 12-grain ( 𝑃 < 0 . 0 3 ) bread, and 12-grain bread was lower than sourdough ( 𝑃 < 0 . 0 0 1 ) and white ( 𝑃 < 0 . 0 0 1 ) breads).
