Here's something I'm definitely going to be using more. From the NPR blog The Salt -- Apples Vs. Oranges: Google Tool Offers Ultimate Nutrition Smackdown.
The gist of the article is, Google has launched a tool to compare nutritional information in food. Just type "Compare (food item) and (food item)" into the search bar and a chart will pop up detailing each item side by side. The Salt says you can tweak the food items being compared -- for example, making mashed potatoes to "potato, mashed, with milk and butter" -- to make those items more specific about how they're prepared. I was having trouble getting that to work properly, but I probably haven't played around with the feature enough.
I think this tool could prove itself very useful for healthier recipes and meals. I look forward to exploring it more.
