Nutrition Education "Shorts": The Effect of Short-Form Media on Conveying Information About Improving Diet Quality.

BACKGROUND

The 2020-2025 Dietary Guidelines for Americans recommends using herbs and spices in cooking to decrease salt, added sugars, and saturated fats (SFA). To promote a healthier eating pattern, there is a need to teach consumers how to do this.

OBJECTIVE

To compare the effectiveness of five short (1 min) nutrition education videos to five longer (5 min) videos by evaluating participants' interest, knowledge, confidence, and likeliness to use herbs and spices in their cooking before and after the videos. To evaluate participant perceptions of the videos and barriers to using herbs and spices in cooking.

METHODS

We conducted a cross-sectional study using a sample of American adults through Dynata. Pre-and post-survey questions inquired about participants' interest, knowledge, confidence, and likeliness to use herbs and spices in cooking. Participants were randomized to view either short or longer videos that included recipe instructions on how to use herbs and spices in cooking. The content of both videos was the same but the format (short and longer video included ingredients and directions while the longer video also included food safety and handling) and duration differed. The videos featured recipes that were lower in salt, added sugars, and SFAs, and herbs/spices were used as a replacement. We also evaluated participants' perceptions of the videos.

RESULTS

Participants ( = 201) were 59% female, 80% White, and had a mean age of 51 (SD = 15) years. All participants reported higher interest, knowledge, confidence, and likeliness to use herbs and spices in cooking after watching the short and longer videos ( < 0.05). Furthermore, participants reported that both short and longer videos were interesting, engaging, conveyed educational information, were easy to follow and understand, and an effective method to increase the use of herbs and spices in cooking. Our analysis revealed no statistically significant differences between short vs. longer videos.

CONCLUSIONS

Overall, both short and longer videos appeared to have a similar impact on consumer interest, knowledge, confidence, and likeliness to use herbs and spices in cooking. Future research should assess changes in dietary intake in response to the videos.
