Spring Onion Nutrition Benefits and Facts

Nutritional summary

Spring onions contain bioactive sulfur compounds and flavonoids that are consistently linked to a reduced risk of gastrointestinal cancers, including gastric and colorectal types .
The green leaves of the plant are more nutrient-dense than the white bulbs, providing higher concentrations of vitamins B1, B2, B3, and C, as well as carotenoids (pigments that support eye and skin health) .
Spring onions contribute to cardiovascular health through a combination of dietary fiber, potassium, and phenols (antioxidant plant compounds) that help manage blood pressure and oxidative stress .
Early research suggests that the specific sulfides found in Allium vegetables like spring onions may play a role in preventing neurological disorders and inflammatory conditions, though more human trials are needed .

Interesting fact

Spring onions and scallions are often the same species, Allium fistulosum, which is unique among onions for never forming a true bulb regardless of how long it grows.
