I find it a bit confusing. What I want is to start fairly simple: track all the macronutrients and micronutrients for my food.Unfortunately, a few things (by example):1. One Google search with USA data claims it has 1.6g (source 1) 1.8g (source 2) of fiber per 100g. Dutch sources [2] claim 0.9g. What am I supposed to make of that? How much can they vary? How accurate is this data?2. Looking at a famous Dutch supermarket [3] I sometimes see different macronutrient or even micronutrient data than the Dutch authorities (see [2]).3. Grocery chains do not give micronutrient data most of the time, just macronutrient data (fiber, protein etc.).And this is simply the basics, how can I best understand this? The reason I want to: the advice in NL is to have 200g of vegetables and 200g of fruit (among other things). However, when I look at the Dutch data, if you eat 200g of vegetables and 200g of food at random, and then toss in some random other stuff in there that is recommended, it seems you'll get a micronutrient defficiency in some of the B-vitamins such as B6, B1 and B2. You're not going to get your daily intake.I haven't formally researched this, but that's what a quick glance gave to me. Instead, you need to quite heavily optimize for it in order to get all your daily intakes met every day.Obviously, not always getting your daily intake won't kill you, but I'd like to have a bit of a higher standard than simply "it won't kill you".So any thoughts on this?[1]  -- both sources came from the same Google search.[2] Voedingscentrum, an Excel export on 100g via the Mijn Eetmeter coaching app.[3] ah.nl
