Your friendly federal government makes available a nutritional
database of more than 7,000 foods that you can download free of
charge, and use as you wish.
You'll find it here:
USDA National Nutrient Database for Standard Reference
Note that there are two different download options:
...Download software to search the SR database, without access to the Internet.
...Download the database for use on your computer with various software packages
There's also a separate download for the database documentation:
...SR18 documentation describing all the files, their fields and
relationships accompanies the database and can be viewed online.
That should do the trick.
But please don't rate this answer until you have everything you need.

The USDA database is a large and pretty comprehensive and free
dataset...that's the good news.
But it's large enough, that it takes a modest amount of effort to get
it up and running in a localized system. Hopefully, the documentation
on the USDA site will help you in this process. But once it's loaded,
it certainly provides calorie info, along with a ton of other details.
As for the data itself, yes, it is in the public domain, and can be
used as you see fit:
Is there a copyright on USDA food composition data?
USDA food composition data is in the public domain and there is no
copyright. We would appreciate it if you would list us as the source
of the data and when possible we would like to see the product which
uses the data or be notified of its use.
Let me know if there's anything else I can help you with.
