This week NPR had also an interesting story - Soda In America: Taxes And A Debate Over Health. Check out also this funny cartoon that I saw in Google Reader.

Web Services

There has been multiple requests to add web services to Food Prints, that's why I created RESTful Web Services to allow developers access to nutrition data stored in Google App Engine. The URL for this is http://food-prints.appspot.com/ws. You'll need to add query string (q) to this to get the results. For instance http://food-prints.appspot.com/ws?q=cheese returns this JSON result:

{
   "Cheese, brie":334.0,
   "Cheese, camembert":300.0,
   "Cheese, brick":371.0,
   "Cheese, cheddar":403.0,
   "Cheese, blue":353.0,
   "Cheese, colby":394.0,
   "Cheese, cottage, creamed, large or small curd":98.0,
   "Cheese, caraway":376.0,
   "Cheese, cheshire":387.0,
   "Cheese, cottage, creamed, with fruit":97.0
}

The strings here are first 10 food names found in the database, and values are calories per 100g of serving. You can get the next 10 results, if any, by passing offset parameter. For instance, http://food-prints.appspot.com/ws?q=cheese&offset=10 returns next 10 results. You can also get serving size for a given food in grams by sending w (for weight) parameter with the exact name of a food. For instance, http://food-prints.appspot.com/ws?w=Cheese, brie returns:

{
   "cubic inch":17.0,
   "cup: sliced":144.0,
   "cup: melted":240.0,
   "oz":28.35,
   "package (4.5 oz)":128.0
}

If you are calling this from javascript, you can also pass callback parameter that will be called when you get the data. I had to use JSONP for cross-site Callbacks to avoid same origin problem with XMLHttpRequest.
This is how I did this in server-side Python code:

def generate(self, object=None):
    callback = self.request.get('callback')
    if callback:
        self.response.out.write(callback + "("+ simplejson.dumps(object)+");")
    else:
        self.response.out.write(simplejson.dumps(object))

The following example shows a complete code that you can copy/paste inside html body tag.

<script type="text/javascript">
function handler(jsonData) { 
 var tableStr = "<table><thead><tr><th>Name</th><th>Quantity</th></tr></thead>";
 for (var food in jsonData) {
  tableStr +="<tr><td><a href='http://food-prints.appspot.com/facts/"+food+"'>"+food+"</a></td><td>"+jsonData[food]+"</td></tr>"; 
 }
 tableStr += "</table>";
 document.getElementById("result").innerHTML = tableStr;
}
var wsURL="http://food-prints.appspot.com/ws?callback=handler&q=";
var script = document.createElement("script");        
script.setAttribute("src",wsURL+"cheese");
document.body.appendChild(script);
function find(){
 document.getElementById("result").innerHTML = "Searching...";
 var script = document.createElement("script");        
 script.setAttribute("src",wsURL+escape(document.getElementById('query').value));
 document.body.appendChild(script);
}
</script>
<input type="text" id="query" value="cheese"/>
<input type="button" onclick="find()" value="Search" />
<div id="result"></div>

Here is how it renders

Updated Nutrient Database to Release 22

I've updated Nutrient Database to Release 22. Restaurant Foods is added as a new group under Browse menu. Around 225 new foods were added to the database and 104 removed (no longer in the market). Here is a list of some of the new foods:

• Grapes, muscadine
• Gold kiwi
• Energy drinks

As part of the American Indian/Alaska Native database, data for 7 food items (ringed seal liver, stinging nettles, caribou, wocas (yellow pond lily) dried seeds and tubers, beaked hazelnuts, and piki bread) were added.

As part of an ongoing effort to expand the number of Latino food items in the database, profiles for tostada shells, sweet breads, cakes, cookies, muffins, horchata, fried green and fried yellow plantains, and dulce de leche have been added.

See SR22 documentation for a detailed list of changes. I've also changed the default weight unit in Nutrition Facts from gram (g) to whatever unit comes first in the database. For instance, the default unit for the goat milk is now 1 cup instead of 100g. All comments and suggestions are welcome.
