Is there any single food that has every micro, macro, vitamin & mineral our bodies need? Or even remotely close to covering them all:
There is literally none I’m afraid… even human breast milk’s nutrient proportions are not suited for a human past infancy and in practice varies on mother’s diet.
Of course you could name something like eggs or soybeans with very good spectrum of vital nutrients and you could live of those but I don’t think there is anything actually close to “20% of all RDAs per 400 kcal” type of thing
