Frequently Asked Questions
Why is watercress the most nutrient-dense vegetable?
The CDC ranked vegetables by nutrients per calorie. Watercress scored 100/100 because it packs extremely high amounts of vitamins K, A, C, and minerals into only 11 calories per 100g - unmatched nutrient density.
Is watercress safe to eat raw?
Store-bought watercress is safe raw. Wild watercress growing near livestock should be cooked to eliminate liver fluke risk. The peppery flavor is most pronounced when raw.
