Yes. SNAP-Ed recognizes three levels of evidence-based approaches: research-tested, practice-tested, and emerging. A Taste of African Heritage is a research-tested approach. A peer-reviewed study published in the Journal of Nutrition Education and Behavior in 2022 shows that participants of ATOAH significantly increased weekly intakes of MyPlate food groups like fruits, vegetables and greens, increased weekly exercise frequency, and also had significant improvements in weight, waist circumference, and blood pressure. The study also identified an improvement in awareness and knowledge of healthy eating from program participants.
Oldways’ African Heritage Diet Pyramid was also referenced in a 2019 article in Nutrients, which found that providing culturally-appropriate interventions, providing flavorful, low-cost plant-based options, and focusing on healthy foods that are already regularly enjoyed in Black cuisine (such as leafy greens, tubers, and okra) are all strategies to promote good nutrition in Black communities. Oldways’ African Heritage Diet Pyramid was also featured in a 2024 article in Advances in Nutrition, which found that traditional African Heritage diets have well-documented benefits for health.
Research shows that making culturally-sensitive modifications to diet programs can lead to improvements in blood pressure, weight, and other health parameters. Though not specific to A Taste of African Heritage, one of the most interesting studies documenting the health benefits of African Heritage diets was a controlled trial published in Nature Communications in 2015.
