Since onions are used in so many different cuisines, they are likely the best source of antioxidants which lend onions their distinct flavor. The antioxidant, polyphenol, protects the body against free radicals which also support a healthy immune system.

Onions are rich in amino acids such as sulfur. Sulfur aids in protein synthesis and the building of cells. Sulfur also acts as a natural blood thinner in turn reducing the risk of heart attack or stroke. As if all these health benefits of onions aren’t enough, there’s more.

Onions increase oxylipins that aid in regulating blood fat levels and cholesterol. Again, reducing the risk of heart attack or stroke.

Another health benefit of onions is anti-inflammatory. Onions have the potential to relieve asthma symptoms. At the same time, the quercetin reduces allergic reactions by thwarting the production of histamines, the things that make us sneeze and itch.

If you are growing and eating onions for health, keep in mind that the benefits are most accessible when the bulb is eaten raw, although cooked onions are still good for you. Raw onions simply have higher amounts of flavonoids, as does the outer layers of onion flesh, so remove as little as possible of the onion when peeling it.
