Impact of the Dinner Tonight Healthy Cooking School on Participants’ Nutrition Knowledge and Cooking Confidence

<b>Background/Objectives</b>: Nearly three-quarters of American adults are overweight or obese, leading to serious health challenges. Poor nutrition is a major contributor, highlighting the need for effective nutrition education and cooking interventions. This study evaluated the impact of the Dinner Tonight Healthy Cooking School (DTHCS) on improving nutrition knowledge and cooking confidence among participants. <b>Methods</b>: A secondary data analysis was conducted on self-reported retrospective surveys collected from 7932 individuals across 64 Texas counties between September 2017 and March 2024. The surveys assessed changes in participants' understanding of key nutrition concepts (rated using a four-point scale from poor to excellent) and their confidence in cooking healthy meals (rated using a four-point scale from none to high) before and after attending the program. <b>Results</b>: The findings showed significant improvements in both nutrition knowledge (from fair to good <i>p</i> < 0.001) and cooking confidence (from low to moderate <i>p</i> < 0.001) following program participation. <b>Conclusions</b>: These results highlight the vital role of nutrition and culinary education in addressing the growing obesity epidemic and reducing the risk of diet-related chronic conditions. Given the positive program outcomes, DTHCS has the potential to inform future studies and guide successful planning and implementation of community-based cooking programs for adults to promote healthier eating behaviors.
