VioScreen™ Research
Tap into a leading dietary assessment for research.
As a nutrition researcher in an academic or business environment, you need dietary analysis software that provides high quality, highly accurate information in a cost-effective and efficient manner. That’s why today’s top health and nutrition researchers turn to VioScreen.
Get 90 days of data in just 20 minutes.

Developed in collaboration with industry-leading researchers and with grant funding from the National Institutes of Health (NIH), VioScreen is scientifically validated dietary analysis software that provides the equivalent of 90 days of nutrition tracking in about 20 minutes.
VioScreen’s dietary analysis utilizes the food and nutrient information from the Nutrition Coordinating Center (NCC) Food and Nutrient Database. It's developed and maintained by the NCC and located at the University of Minnesota Division of Epidemiology and Community Health in Minneapolis.
VioScreen is used by leading medical research universities and such government health agencies as NIH. It has also been used as a dietary intake reporting method to the FDA for a worldwide type 1 diabetes Phase III trial.

Reduce the time, cost and complexity of managing your nutrition research study.
With its unique, graphical Food Frequency Questionnaire (FFQ), branching logic, analytics engine and simple user interface, VioScreen dramatically reduces the time, cost and complexity of managing and running nutrition research studies. This cloud-based, self-administered questionnaire collects data on a subject’s dietary behavior and food use patterns, estimates nutrient intake and delivers detailed dietary analysis data and reports.
Simple to use. Simple to administer. Simply better.From any internet enabled computer or tablet, your subjects answer eating behavior questions about foods, frequencies and portion sizes through a web-based dietary questionnaire in English or Spanish. As the first online FFQ to incorporate branching logic and portion size images, VioScreen intuitively updates questions based on a subject’s previous answers. Memory probes are included to prompt subjects for more detail. In addition, subjects select the best portion size from images with different amounts of food, which greatly improves the quality of dietary assessments.

Real-time results. More accurate and easier to administer than paper FFQs.

VioScreen's simple design increases accuracy while eliminating the tedious management and manipulation of paper FFQs. The simple design also means that subjects don’t need to have a high reading comprehension level. Once a subject completes our web-based FFQ, you’ll have results in real-time, available as reports and exportable data sets. With VioScreen, you'll get:
VioScreen is not just for subject data collection; it makes the entire process easy to manage. You can define organizations and protocols, assign user roles, view results and export results to a standard file format for import to analytical software.
- Improved accuracy.
- No missing or mismarked questions.
- An improved questionnaire design that enables the collection of more data in less time.

VioScreen in action.

VioScreen is used in a wide range of research applications.
- Investigators use VioScreen for dietary assessment in their research protocols.
- Universities incorporate VioScreen into large-scale epidemiological studies that have dietary end points.
- Institutions incorporate VioScreen in clinical drug trials for diseases impacted by nutrition, particularly when required by the FDA to demonstrate that the dietary input has been controlled throughout the study.
Validated for high accuracy. Excellent ratings from subjects.
In an NIH-funded validation study conducted and analyzed independently at the Ohio State University and published in the Journal of the Academy of Nutrition and Dietetics (JAND), VioScreen received high scores for reliability, accuracy and ease of use.
