Nutrium has a wide number of food composition databases. Despite that, if you are searching for a specific food and can't find it, you can always add it to your own database in a very simple way.
To add a new food you need to go click in the section "Foods" on the left sidebar menu. After that, you need to click in the "+" sign ou in "Add new food". Register the name of that new food and the nutritional information per 100 grams.
Once that is done, click on "Common measures" to give your new food its usual portion, such as tablespoon, glass, slice.
Once your new food is created it will be available in the section "Meals" included in the database "My foods".
This allows you to create your meal plan and to have all your own foods organized in one place giving you quick access to them.
