Impressive Health Benefits of Onions
1. Packed With Nutrients
Onions are nutrient-dense, meaning they’re low in calories but high in vitamins and minerals.
One medium onion has just 44 calories but delivers a considerable dose of vitamins, minerals and fiber.
This vegetable is particularly high in vitamin C, a nutrient involved in regulating immune health, collagen production, tissue repair and iron absorption.
Vitamin C also acts as a powerful antioxidant in your body, protecting your cells against damage caused by unstable molecules called free radicals .
Onions are also rich in B vitamins, including folate (B9) and pyridoxine (B6) — which play key roles in metabolism, red blood cell production and nerve function
2. May Benefit Heart Health
Onions contain antioxidants and compounds that fight inflammation, decrease triglycerides and reduce cholesterol levels — all of which may lower heart disease risk.
Their potent anti-inflammatory properties may also help reduce high blood pressure and protect against blood clots.
Quercetin is a flavonoid antioxidant that’s highly concentrated in onions. Since it’s a potent anti-inflammatory, it may help decrease heart disease risk factors, such as high blood pressure.
Loaded With Antioxidants
Antioxidants are compounds that inhibit oxidation, a process that leads to cellular damage and contributes to diseases like cancer, diabetes and heart disease.
Onions are an excellent source of antioxidants. In fact, they contain over 25 different varieties of flavonoid antioxidants .
Red onions, in particular, contain anthocyanins — special plant pigments in the flavonoid family that give red onions their deep color.
Contain Cancer-Fighting Compounds
Eating vegetables of the Allium genus like garlic and onions has been linked to a lower risk of certain cancers, including stomach and colorectal.
Boost Bone Density
Though dairy gets much of the credit for boosting bone health, many other foods, including onions, may help support strong bones.
A study in 24 middle-aged and postmenopausal women showed that those who consumed 3.4 ounces (100 ml) of onion juice daily for eight weeks had improved bone mineral density and antioxidant activity compared to a control group
Have Antibacterial Properties
Onions can fight potentially dangerous bacteria, such as Escherichia coli (E. coli), Pseudomonas aeruginosa, Staphylococcus aureus (S. aureus) and Bacillus cereus
May Boost Digestive Health
Onions are a rich source of fiber and prebiotics, which are necessary for optimal gut health.
Prebiotics are nondigestible types of fiber that are broken down by beneficial gut bacteria #medicalawarenessintamil #onion_benefits
