Eating only 'good' calories

Do you seek out delicious foods that are tasty and have "good" calories instead of consuming "empty" calories (like most soft drinks)? If so, you'd probably like the idea of a doctor in Singapore who maps out the best street food based on how much "full" calories there are in the meals being served.

This would make a great idea for someone in an area with many street food vendors, like in Southern California or New York City.

Talk about an opportunity for a healthy-conscious street food vendor to drum up business from virtual scratch and retain a decent and loyal customer following. What a great idea!
