Generative AI for food formulation: Designing healthy, sustainable, and delicious burgers
Abstract:
Our food choices impact both human health and the environment, yet creating foods that are simultaneously tasty, nutritious, and sustainable is difficult. This research shows that generative AI can learn patterns of human taste from large recipe datasets and design new foods. Using burgers as a case study, our model independently rediscovers the Big Mac and generates burgers optimized for taste, sustainability, or nutrition. The burgers optimized for taste matched or outperformed the Big Mac in a blinded survey with 101 participants, while its sustainable and nutritious versions achieved substantially better environmental and health scores. We also demonstrate that the generation process can be personalized by tailoring recipes to an individual’s sex, age, weight, and physical activity level. This capability could be particularly valuable for athletes, for whom individualized nutrition planning is essential.

Leg Dexterity Training Reduces Drop-Test Dynamic Valgus in Amateur Women Athletes: A Pilot Study
Abstract:
Non-contact Anterior Cruciate Ligament (ACL) injuries disproportionately affect amateur athletes who are girls and women. Dynamic valgus during a drop test is used to evaluate the risk of ACL injury. We will present evidence suggesting that training leg dexterity while seated (the dynamic control of unstable foot-ground interactions) by itself reduced dynamic valgus in 17 females ages 18-25. This supports the hypothesis that training short-latency sensorimotor responses may be an effective tool to complement available approaches (e.g., training landing mechanics and strengthening hip muscles) to mitigate risk of ACL injury in these populations.
About the Seminar Series
The seminar series features speakers from across the institutions that make up the Alliance, covering topics related to our mission of uncovering the principles of performance and translating them to improved performance and care of athletes and all people.
The goal of the seminar series is to foster scientific exchange and the formation of new research collaborations through a set of research talks that are clear and compelling to researchers from a broad range of fields.
