Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Food Intake Study: This will be a 4-week randomized controlled intervention study with a vegetable intake questionnaire, daily food intake, and seasoning usage measurement to test the acceptability of different seasoning ingredients and vegetable intake in healthy adults. Participants will be randomly assigned to one of three groups (a) vegetables prepared with 50% NaCl and 50% MSG (50/50MSG Mix); (b) vegetables prepared with 70% NaCl and 30% MSG (70/30 MSG Mix); (c) vegetables prepared with NaCl (table salt). Sensory Evaluation Study: A sensory evaluation utilizing all seasoning methods from the intervention will be conducted at a Texas Tech University culinary education lab. In a Texas Tech University culinary education lab, 2-4 vegetables will be cooked and seasoned with either 50/50MSG Mix, 70/30 MSG Mix, or NaCl for taste testing. Then, using a standardized form, participants will rate their acceptability and preference of each vegetable, including sensory characteristics such as appearance, color, odor, texture, and flavor.
