Often avoided for the pungent and nasty breath it leaves you with, onion, especially red onion has much more to it than just its taste. Red onions are worth the tears as they contain nutrients such as chromium and quercetin that can reduce inflammation, fight free radicals, and also improve your gut health. Try retaining the outer layers of onions as they are rich in fiber, antioxidants, and flavonoids. Although red onions and white onions are quite similar, red onions are better as they contain higher amounts of beneficial nutrients.
Here are 5 reasons why you must eat red onions.
1. Lowers Risk Of Cancer
2. Improves Heart Health
While low-density lipoprotein (LDL) or “bad cholesterol” increases the risk of heart diseases, high-density lipoprotein (HDL) or “good cholesterol” reduces its risk. Bad cholesterol is one of the major cause of atherosclerosis as the build-up of plaque in the arteries narrows them and prevents proper blood flow.5
3. Aids Digestion
Red onions contain inulin, a soluble plant fiber that is not broken down during digestion as it has the ability to act as an insoluble fiber. This property of inulin makes it beneficial for your gut health.7
4. Regulates Blood Sugar
Red onions are a rich source of chromium, which can control blood sugar levels. This is good news for diabetics and people trying to lose weight as eating onions won’t lead to blood sugar fluctuations.
5. Fights Inflammation
Quercetin, due to its anti-inflammatory properties can lower bad cholesterol, reduce the risk of heart disease and cancer. In addition to these benefits, it can reduce the symptoms of osteoarthritis and rheumatoid arthritis by inhibiting leukotrienes, prostaglandins, and histamines which cause inflammation.
Eating red onions can also boost your immune system by reducing inflammation. Infections can activate your immune system and lead to inflammation. Quercetin in red onions can reduce both the inflammation and the infection.11
