How Green Onions Prevent Chronic Disease
Green onions contain beneficial nutrients and antioxidants that make them a great resource for chronic disease prevention.
How Green Onions Prevent Cancer
Green onions help prevent several cancers. They have antioxidants that can prevent free radicals from damaging tissues and causing inflammation. Free radicals exert oxidative stress on tissues. As a result, they can lead to cancer cells proliferating and metastasizing over time. It is important to have foods that are rich in antioxidants to prevent these adverse effects and minimize free radical damage. (2)
Green onions are part of the Allium family, along with garlic and onions. Compounds in the Allium family provide enhanced antioxidant effects, and studies have shown that these vegetables reduce your risk of several cancers. (3) They specifically lower risk of gastric, colorectal, lung, and prostate cancers. (4)
Studies show that green onions can lower inflammation and suppress the growth of tumors in mice. More studies are needed to confirm these results. (5)
Green onions can release a compound called allicin, which has also been shown to stop the growth of cancer. (6)
How Green Onions Prevent Cardiovascular Disease
Green onions have been shown to prevent cardiovascular events by supplying vitamin K. Vitamin K plays a critical role in managing blood clots and can prevent stiffening of the arteries. (7)
Also, green onions, specifically scallions, have been shown to lower total cholesterol and LDL (bad) cholesterol levels. It is important to minimize LDL cholesterol in your blood system because, as it builds up, it clumps together and blocks blood flow. This can often lead to a cardiovascular event, such as a heart attack, if left unaddressed. (8)
It is important to consume foods rich in HDL (good) cholesterol to help prevent LDL plaque buildup. HDL cholesterol can help eliminate excess LDL cholesterol from the blood stream. Maintaining an optimal HDL: LDL cholesterol ratio is essential for proper cardiovascular health. (9)
How Green Onions Prevent Diabetes
Green onions are nutrient-dense foods and low in calories. With that being said, green onions have a proportionately good ratio of fiber to mass, which helps lower risk of diabetes. Fiber plays an important role in reducing your risk of diabetes by keeping you fuller for a longer period of time and preventing overconsumption during meals as a result. Foods that are low on the glycemic index and provide fiber are generally prescribed for diabetes prevention. (10)
Green Onions Promote a Number of Health Benefits
How Green Onions Promote Bone Health
Vitamin K plays an important role in bone health. Vitamin K provides additional strength and density to your bones by helping them retain bone calcium and recruiting proteins needed to keep bones strong. (11)
You can reduce your risk of fractures and conditions such as osteoporosis or rheumatoid arthritis by consuming high levels of vitamin K.
How Green Onions Promote Digestive Health
As mentioned above, green onions, specifically scallions, are relatively rich in fiber. Fiber is crucial for maintaining proper bowel movements and overall digestive health. Specifically, soluble fiber can help feed your healthy gut bacteria, allowing your digestive tract to function optimally and absorb nutrients efficiently. (12)
