but it does not say how or where this information is taken from.
The TLDR is not every food needs to be lab tested as long as they can take their ingredients and compare them against national databases (e.g. NCCDB) to estimate nutritional info. And yes, some of the data in those databases is old and perhaps overly general - it's totally reasonable to suspect that vegetables grown in one area, as part of a specific breeding line, in a certain manner, have totally different nutritional info compared to the same generic vegetable grown elsewhere in a different manner.
However keep in mind a lot of food does not list all micronutrients as part of their labelling. This actually kinda drives me nuts and I have no idea why e.g. frozen vegetables don't list things like Vitamin K, magnesium, and zinc when they're often actually good sources of many nutrients.
>One comment suggested vitamin D fortification should be viewed as hormone replacement therapy
Found that particularly humorous
From that angle, I can understand how they arrive to that conclusion, while perhaps still disagreeing. The interplay within the human body is almost mind-blowingly complex to me
