- 01Among the noteworthy findings was that offering vegetables with a reduced-fat dip containing herb and spice flavors increased tasting, liking, acceptance, and/or consumption of vegetables among preschool children 3-5 years old. [Johnson GH (2026)]
- 02Consumers reported increased liking of an herb and spice-modified low-salt (LS) soup after repeated exposure, while no such increase was seen for its LS counterpart without spices and herbs. [Johnson GH (2026)]
- 03Studies in the category of metabolic health have reported that speed of working memory was increased by an acute low dose of rosemary (750 mg) provided in tomato juice among free-living elderly study participants (65-90 years of age), whereas the opposite effect resulted from the highest dose (6000 mg). [Johnson GH (2026)]
- 04This review is an analysis of reported studies that address the broad categories of diet quality and metabolic health. [Johnson GH (2026)]
