What it is

Red onions are a variety of onion (Allium cepa) known for their purplish-red skin and flesh. They grow underground as bulbs and are cultivated worldwide. Red onions are typically eaten raw or cooked, offering a milder, sweeter flavor than yellow onions.

Why it's used

Red onions are used as a flavoring ingredient, adding a pungent, slightly sweet taste to dishes. They are commonly found in salads, sandwiches, salsas, and as a garnish. Manufacturers use them in a variety of prepared foods, including pickles, relishes, and deli salads.

Health notes

Red onions are a natural food ingredient and are generally recognized as safe (GRAS) by the FDA for use in food. They contain various beneficial compounds, including antioxidants like quercetin. While generally considered healthy, no specific health claims are approved by regulatory bodies for red onions at typical dietary intake levels. International bodies like EFSA have evaluated onions as food, but no specific evaluations for red onions alone are typically highlighted.

Allergen info

Red onions are not one of the nine major allergens recognized by the FDA. They do not contain gluten.
