use NL nutrition database
In NL there's a database that anyone can access or connect to. If only you would use it to put in products in your app then we wouldn't have to submit them ourselves, and they can be updated from that source as well since every few months they are lowered in calories by the manufacturers. In this database the suppliers put their all data, such as calories, fat, saturated fat, salt, carbs, sugars etc etc. This way you can have more products that are verified, and less (to none) need to be added, and adding products will be more of an exception instead of it being the norm.
Oh and please please just merge the brands AH and Albert Heijn and eliminate different ways of writing this (with the exception of AH Basic and AH Excellent which are actually different (private label-) brands)
