Soil research matters. It does not justify converting a darker soil picture into a guaranteed vitamin increase or a personal health score.
What’s worth understanding
A 2022 preliminary study reported differences in selected crop nutrients and phytochemicals across small farm comparisons.
Small, non-randomized comparisons are not controlled human feeding trials. Results cannot be generalized to every crop, farm or person.
General dietary guidance emphasizes vegetable variety within an overall healthy eating pattern.
