The search feature, which will display protein, carb, fat and salt content for almost all foods, is being launched in the US this week.
Dieters will even be able to ask a question using a microphone on their cellphone or laptop.
A blog post by Google claimed the new tool will enable women and men to make better food choices.
It stated: “We’re hoping we can make those choices a little bit easier: starting today 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.'
“You'll hear the answer to your specific question, see relevant nutrition information under an expansion, and be able to switch to other related foods or serving sizes.”
The blog post goes on to explain that the new nutritional information builds on work on the Knowledge Graph.
The graph uses Google's search results along with information from a wide range of websites to give searchers detailed and specific information about a particular topic, all in one place.
As part of the nutritional information roll out, the graph helps connect related subjects, even in cases when those foods have a completely different sounding name from what you asked.
For example, if you ask about nutritional information concerning 'summer squash carbs', Google will include 'zucchini' as a relevant food in the dropdown, because it is a type of summer squash.
The blog post adds: “Over time we’ll be adding more features, foods, and languages.
“So tap the microphone, give the feature a spin, and soon explore and discover the ins and outs of over 1,000 of your favorite foods.”
