If you like detailed nutrition information about food and beverages, consult the USDA nutrient database. It covers thousands of fresh and packaged foods (including brand-name products) and is the only such database that’s free and kept up to date.
To get average nutrient values as opposed to numbers for specific brands, click on “standard reference” under “filter on database.”
The website is really designed for nutrition professionals, thus it doesn’t put the nutrient values in context, as does the Nutrition Facts box on food labels, which also includes the “% Daily Value” for some nutrients. To make sense of the numbers, you can compare them to the Recommended Dietary Allowances (RDAs) for vitamins and minerals.
