Red Onion
Red Onion (Allium cepa), also known as Purple Onion or Spanish Onion, is a type of onion that is characterized by its deep red or purple skin and round shape. The pronunciation of Red Onion is /rɛd ˈʌn.jən/.
Etymology
The term "Red Onion" is derived from the Latin word "unio", which means "single" or "one", reflecting the onion plant's production of a single bulb, unlike its relatives in the Allium genus that form clusters of bulbs. The "red" in Red Onion refers to the color of its skin.
Description
Red Onions have a mild to sweet flavor, often more so than their white or yellow counterparts. They are commonly used in salads, salsas, and other raw preparations for their color and relatively mild flavor. The red color comes from the high levels of anthocyanins, a type of flavonoid that provides many health benefits.
Health Benefits
Red Onions are rich in vitamin C, sulfuric compounds, fiber and flavonoids. They are known for their antioxidant properties, which can help to fight against free radicals in the body. They also have anti-inflammatory properties and can help to lower cholesterol levels.
