Rating Food and Drink products

There are many systems and ways to rate food. Yale's Dr. David L. Katz, for example, uses a rating system called the Overall Nutritional Quality Index (ONQI). The Katz system evaluates all foods in a grocery store on a 1-to-100 scale, with 100 being the healthiest.

Nutritiondata developed their own rating system, including the Caloric Ratio Pyramid™, estimated Glycemic Load™, and inflammation Factor Rating™.

Other systems are based on collective intelligence - like hopchart for rating beer.

The founder got into craft beer a few years ago and decided to make a system to track wh

at he drank and give it a rating.

There are plenty of beer rating sites on the internet (Beer Advocate, RateBeer, etc) but they allow only one rating of a given beer. According to Andrew, if a Beer Advocate rating is like a blog, then a HopChart rating is like a tweet. Map-like features are planned to be implemented soon. And if you are feeling adventurous and want to enjoy a different night out, try localvortex - a geo-locator of nearby bars.

Another example of an application allowing food ratings is Food Prints

developed by Sargis Dallakyan on Jan 10, 2009 - with good ratings from the users:

This app allows you to search and browse nutrition facts from food labels. Users can change serving size and view images generated by Google search. The back-end is powered by Google App Engine and Django. The front-end is using Yahoo! User Interface Library, Google AJAX Search and Adobe Flex.

More general applications like Eat.ly or GoodGuide, allow to rate foods too, among other consumer products.
