What it is
Red onions are a variety of the onion plant (Allium cepa), known for their vibrant purple-red skin and flesh. They are grown worldwide and are a staple vegetable in many cuisines. Red onions are typically consumed raw or cooked, adding a pungent flavor and color to dishes.
Why it's used
Red onions are primarily used as a flavoring ingredient, adding a sharp, slightly sweet taste to foods. They are commonly found in salads, salsas, sandwiches, and as a garnish. Their color also contributes to the visual appeal of packaged foods like dips and pre-cut vegetable mixes.
Health notes
Red onions are a source of various nutrients and antioxidants. The U.S. Food and Drug Administration (FDA) generally recognizes onions as safe (GRAS) when used for food. International bodies like the European Food Safety Authority (EFSA) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) have evaluated onion components, often in the context of dietary exposure. Research suggests potential benefits from compounds found in onions, but more studies are needed to confirm these effects at typical dietary intake levels.
