Which relatives of the round onion are noted for packing a powerful nutritional punch?

Answer

Spring onions (scallions) and shallots

Beyond the standard round varieties, close relatives within the allium family contribute valuable nutrition. Specifically mentioned are spring onions, often called scallions, which are harvested before the bulb matures and offer a delicate flavor dimension. Shallots are also cited as important additions, as they share characteristics with both garlic and onions and should not be ignored in the pursuit of diverse health advantages. When considering the entire family—which also encompasses chives and leeks—a broader range of protective compounds becomes available to the consumer.
