Red onions, sometimes called purple onions, are
cultivars of the onion with purplish red skin and white flesh tinged with red.
These onions tend to be medium to large in size and have a mild to sweet flavor.
They are often consumed raw, grilled or lightly cooked with other foods, or
added as color to salads. They tend to lose their redness when cooked.
Red onions are available throughout the year. The red color comes from
anthocyanidins such as cyanidin. Red onions are high in flavonoids.
They can be stored 3 to 4 months at room temperature.
Health Benefits of Red Onions
By Mark Orwell, eHow Contributor
No kitchen is complete without a red onion. They
may make you cry, but they're on your side when it comes to taste and health.
Red onions can be used in so many recipes that you'll probably find yourself
buying them regularly. Onions are full of nutrients that will give a boost to
your health.
Blood-Sugar Level
The more red onion you eat, the lower your blood-sugar glucose levels will
be. This is because of allyl propyl disulfide and chromium, both of which are
are found in red onions.
Gastrointestinal Health
If you are looking to lower your chances of colon cancer and related
diseases, add red onions to your diet at least twice a week. Quercitin, one of
the flavinoids found in onions, is known to be very beneficial to
gastrointestinal health.
Bones
A study in the Journal of Agricultural and Food Chemistry found that red
onions are also beneficial to overall bone health. A compound known as GPCS is
responsible for this, and it does so by inhibiting cells that break down bones.
Antiinflammatory
Red onions reduce inflammation in the bones and throat, as well as in blood
vessels. This reduces many of the symptoms of osteoporosis, asthma and even the
common cold.
Cardiovascular Health
The chromium and vitamin B6 found in onions helps to increase cardiovascular
health. Specifically, these compounds lower blood pressure and cholesterol.
