meal planning apps vs. templates -- less features with templates i.e. meal tracking, logging dining

with apps like cronometer, eat this much, and meal lime, it's hard to say whether meal planning templates will become obsolete unless there's a way to scrape food databases for accurate nutrition facts, like how their apps do. the nutrition facts on the premade foods in their database aren't always on point. for example, chocolate has A TON of zinc, but it doesn't show up in my favorite chocolate products. if i logged the ingredients manually for those products, though, i would see this data on zinc and other minerals. the ai isn't very "i." maybe it needs to pull from different sources to calculate the nutrition so people have the most accurate data to know they're meeting or not meeting their targets. how could one accomplish this?
