A four-week spice experiment challenges expectations about post-meal benefits

Culinary doses of herbs and spices did not significantly alter postprandial endothelial function, glycemia, or lipemia after four weeks of corresponding spice-containing diets in adults at cardiometabolic risk. The findings suggest that acute spice-related effects may be less apparent with longer-term exposure, although the study may have been underpowered to detect modest benefits.
