Varieties in the mineral study
Only Brassicaceae crops were included.
What do the studies actually say?
Numbers stay within the limits of their source study.
Vitamin C, carotenoids, vitamin K and vitamin E
Vitamin C ranged from 20.4 to 147.0 mg/100g fresh weight; results varied widely by variety.
The study did not provide a universal calorie, protein or fiber table for all microgreens.
Xiao et al. (2012), Journal of Agricultural and Food ChemistryCalcium, copper, iron, magnesium, manganese, phosphorus, potassium, sodium and zinc
Mineral concentrations differed by type; potassium was the most abundant mineral overall.
These Brassicaceae results should not be applied unchanged to sunflower, pea shoots or every growing system.
Xiao et al. (2016), Journal of Food Composition and Analysis / USDA ARSProtein and fiber on a fresh-weight basis
Crop means ranged from 2.34 to 3.12 g protein and 0.355 to 0.681 g fiber per 100g fresh weight.
This three-crop experiment is not a complete ranking for every microgreen.
Palmitessa et al. (2020), FoodsVitamins, phytochemicals, protein and nine minerals on a fresh-weight basis
Vitamin C ranged from 32.37–36.00 mg/100g in Delhi and 61.11–88.63 mg/100g in Leh-grown samples.
The location and genotype differences show why one value cannot label every mungbean microgreen.
Priti et al. (2021), Frontiers in Plant ScienceHarvest window
7–21 days
Penn State describes microgreens as harvestable roughly 7–21 days after germination, depending on species and conditions.
Four checks for any nutrition chart
01 · Crop
Species and cultivar should be identified.
02 · Unit
Fresh and dry weight must stay separate.
03 · Method
Measured compounds and laboratory method should be visible.
04 · Limit
One study should not be generalized to every microgreen.
