Figure 5

The time course of changes in mean (± SEM) systolic and diastolic blood pressure during monosodium glutamate (MSG) and placebo intervention. As there was no effect of day, a grand average of the results of all 5 days is shown. Note that there was a small, but significant (*: P < 0.05) increase in both systolic and diastolic blood pressure 15 and 30 minutes after ingestion of MSG, but no change in blood pressure after placebo.
