Compared to reference vegetables like spinach, how much greater was the ORAC capacity in some fern extracts?
Answer
Nearly ten times greater
Fiddleheads demonstrate exceptional antioxidant properties, which are quantified using assays like the Oxygen Radical Absorbance Capacity (ORAC). Scientific investigations comparing European fern species extracts against established reference vegetables, such as spinach and rocket, showed a significant superiority in antioxidant capacity. Specifically, the measured ORAC assay results indicated that some fern extracts possessed an antioxidant capacity nearly ten times greater than that found in the reference vegetables. This extreme potency underscores the significant boost these seasonal greens offer against oxidative stress compared to more conventional greens.
