Top 50 Food Questions – Video Series

Scientific Answers to Your Food Questions

Many consumers walk the grocery aisles and food markets in a fog—overwhelmed by the amount of data, confusing labels, and vast array of choices. As they reach for items from the shelves, shoppers don’t have time to review scientific papers—and that’s where CAST comes in. CAST is creating a series of 50 informative, entertaining 90-second videos that will be professionally written, produced, and distributed. Each addresses one question that people want answered about “Food”—food safety, food ingredients, farming and production methods, or environmental impacts. Each video provides facts with answers scripted by food science experts and edited in understandable language by CAST. By answering key questions about food, CAST clears the air for those consumers in the aisles.

Enjoy these sample videos. For more information on how to support production of videos to answer a food question like the ones listed below, please contact Kent Schescke at 515-292-2125 ext. 231.
