About
RxFood began as Inner Analytics Inc., co-founded by Elizabeth Choi and Dr. Jeff Alfonsi. Its first product launched in 2015 through a partnership with The Hospital for Sick Children in Toronto, helping children and adolescents with Type 1 diabetes work out what they had eaten, and the Physicians Services Incorporated Foundation later funded a randomized controlled trial of it. The premise is that dietary assessment is the bottleneck in nutrition therapy: patients photograph their meals, machine vision estimates the nutritional content, and clinicians get usable data instead of a food diary nobody fills in. By 2019 the company was extending beyond diabetes to hypertension and obesity. It now trades as RxFood, describes itself as a clinically validated dietary-therapy platform, integrates with wearables such as continuous glucose monitors, and names SickKids, the Cleveland Clinic and Ontario Health among the organisations it works with. In 2025 it began a commercialization project with CHEO's diabetes clinic in Ottawa through the CAN Health Network. Alfonsi represented the company on TechTO's HealthTO stage in May 2020, on a panel about whether COVID-19 would accelerate virtual health care.
Backers
No named investor is on the public record. The randomized controlled trial of its first product was funded by the Physicians Services Incorporated Foundation, which is a research grant rather than an investment.
