Since 2013, Google added a way to provide the search user with accurate information about the food and nutrition from reliable sources like USDA.
The information is not just about the calories, but also includes detailed nutrition chart. It uses Google's knowledge graph to display the information in a tabular format on the right site of the search results.
You can compare nutrition information for two fruits using search operator like 'Compare'. For example, if you use search string, 'Compare oranges and peaches' it will display comparisons between two fruits for calories, carbs and other vitamins.
You could compare any two fruits and could have the comparison chart as a first thing in search results. Of course, that is as long as Google has the information.
What you can't do though is compare three fruits at once. You should't need that as long as comparing two fruits work perfectly fine.
Knowing Calories in anything you eat is Good but having that information just a click away is the best thing technology can offer.
Google offers Calorie information to almost all the food we eat. For example when you search 'calories in watermelon', you are displayed with the calorie information for a specific quantity of watermelon.
It's not just that but you are offered the choices to select the type of watermelon and quantity.
It will display a picture of watermelon and the definition of watermelon from authoritative sources like Wikipedia.
Nutrition Facts will display the most valuable information including Calories, Fat, carbohydrate and other constituents.
All this information displayed in a readable format on the first page of the results couldn't get any better.
The use of operator or a string is really very flexible considering the user behavior. For instance, 'formula water' will yield the chemical formula for water as well as the composition and other chemical details of the water.
Similarly, if you tried searching 'beer calories' Google will display the same results it would have displayed for 'calories in beer'. As usual this results will be accompanied with type and quantity drop-down menu for you to select what type of beer and the quantity for which
calories are to be displayed.
The additional value comes from the provision to select the specific type of food. For instance, if you search for 'calories chicken' it will display the calorie details just below the search result bar and on nutrition facts on the right side.
Now, you could not only select the part of the chicken you want to eat, but also the method of cooking, like - Chicken, breast, roasted. It will display the exact calories expected out of the selected food type.
Next time you hear apples and oranges cannot be compared, prove them wrong with Google search!
