The Globe and Mail reports in its Monday edition that an AI-powered app called RxFood allows users to snap pictures of their food and the app will quickly generate an estimate of its carb, calorie, protein and fat levels. The Globe's Sean Silcoff writes the app can also produce a detailed report on a user's diet and offer daily tips to improve it. There are many apps for tracking what people eat. Major health care players are referring the app to diabetics. It is backed by a dozen clinical studies that show people using RxFood have significantly improved the accuracy of their carb-counting efforts, reduced their glucose levels and saved time managing their diabetes by reducing the amount of time needed to monitor and record their food intake. "We've been able to prove it's as good as medication" that controls glucose levels, such as metformin, or other nutritional therapies, said Elizabeth Choi, chief executive officer of the company behind the app, RxFood Co. That has helped turned the 55-person company into one of Canada's most promising digital health start-ups. Sun Life is testing it on 100 people in the Philippines to help develop term insurance products for diabetics and others who would otherwise be uninsurable.
