Eetmeter
Eetmeter (eat meter) is a Dutch food consumption tracking web app. The user enters the food and quantity eaten during each day. The site makes use of an extensive nutrition database allowing the user to see in detail which nutrients he or she is consuming too much or too few. The whole site is in Dutch, but it is free and run by a governmental organisation (so there are no advertisements or (hidden) business models which involve your data).
