Google can now answer questions about nutrition, but it's strange to see that this feature only works if you use voice search in Android, iOS or Chrome. "You will be able to quickly and easily find extensive nutrition information for over 1,000 fruits, vegetables, meats and meals in search. From the basics of potatoes and carrots to more complex dishes like burritos and chow mein, you can simply ask, 'How much protein is in a banana?' or 'How many calories are in an avocado?' and get your answer right away," informs Google.

It works for general questions like 'how many calories are in carrots' or for queries like 'carrots calories'.


By default, Google shows the number of calories in a medium carrot, but you can pick a different serving size: 1 slice, 100 grams, 1 cup grated and more. For now, you can't enter a custom serving size.


You can also disambiguate your query. If you search "tuna calories", you can select from bluefin, skipjack and yellowfin. Unfortunately, the list is incomplete and you can't select canned tuna.


Google shows a knowledge graph card with information from Wikipedia and nutrition facts, so you can quickly find the amount of saturated fat, cholesterol, protein or vitamins and minerals without clicking a search result.


And it's not all about calories. You can also ask: 'how much protein is in an egg?', 'how much cholesterol is in chicken?', 'how much saturated fat is in butter?', 'how much sugar is in Coca Cola?', 'magnesium in an apple', 'vitamin C in parsley'.


The feature only works in English and it's gradually rolling out, so it may not work for you. Try it in Android's Google Search app, Google's app for iOS or in Chrome (click the microphone icon from the search box).

Amit Singhal announced at Google I/O that this is "the end of search as we know it". The future of search goes beyond search results and it has more to do with answering questions, conversations and anticipating user's intentions.

Google has 3 products with similar goals: Knowledge Graph, Voice Search and Google Now. They go hand in hand to deliver the future of search today.

Voice Search has been available on the desktop if you're using Chrome, but now it's much better: it has been upgraded to the conversational voice search released last year for Android and iOS. Just click the microphone icon from the Google search box, ask questions and you'll get a spoken answer. Soon you'll be to just say "OK Google" to trigger voice search.


Google Search for Android added some new Google Now cards: reminders, last train home (Japan only), real time public transit updates and recommendations for books, games and music albums. Google Now can understand things like "remind me to call Susan tomorrow at 10", "when I go to Rome, remind me to buy a new suit" or "remind me to meet Dan when I get to work". You can create both time-based reminders and location-based reminders.


Voice Search is getting more sophisticated, the Knowledge Graph has more facts and connections between concepts, while Google Now gets smarter and tries to anticipate your searches.

Google tests a new feature of the knowledge sidebar: a link that invites you to "explore more". The Knowledge Graph section doesn't allow Google to show more than 5 related people, books, albums, movies, so the experiment displays more of them below the search box.

For example, when you search for a movie and click "explore more", Google shows more cast members. You can use the arrow icons to switch to a different category.

As previously anticipated, Google introduced Knowledge Graph, a new way to handle queries that replaces keywords with objects. It's like replacing a dictionary with an encyclopedia.

"The Knowledge Graph enables you to search for things, people or places that Google knows about—landmarks, celebrities, cities, sports teams, buildings, geographical features, movies, celestial objects, works of art and more—and instantly get information that's relevant to your query. This is a critical first step towards building the next generation of search, which taps into the collective intelligence of the web and understands the world a bit more like people do," explains Google.

For now, you'll only notice a new info pane in the right sidebar that shows more information about your query. Google's graph has 500 million objects and 3.5 billion facts, so you'll see the new section quite often. Google shows a small thumbnail, a snippet from a Wikipedia article, a few relevant facts and some related queries. It's just like a Wikipedia infobox automatically generated using data from the Web and that's smart enough to only show important facts and hide the things people won't need.


The new info panes will also help users disambiguate queries just like Wikipedia's disambiguation pages help users find the right articles.


Wikipedia's internal links help you find other interesting articles. Google also adds links to all the other objects from the graph.

Some may say that Google borrowed too many ideas from Wikipedia, but that's one step that could help search engines evolve. Understanding the relation between entities and learning their attributes allows Google to answer more complicated questions and get better search results. As Mashable says, "the transition from a word-based index to this knowledge graph is a fundamental shift that will radically increase power and complexity."

Google "begun to gradually roll out this view of the Knowledge Graph to U.S. English users. It's also going to be available on smartphones and tablets". If you don't see the new features yet, check back later.
