Health Canada recently launched a website called My Food Guide that allows people to create their own healthy eating guide using the foods they eat most often. And that site includes a whole host of ethnic foods, including congee, hummus and lychee fruit. The site is geared towards Canadians, but I hope they don't mind sharing the love with some southerly neighbors.
