Possible health benefits of consuming onions
Consuming fruits and vegetables of all kinds has long been associated with a reduced risk of many lifestyle-related health conditions. Many studies have suggested that increasing consumption of plant foods like mangoes decreases the risk of obesity and overall mortality, diabetes, heart disease, and promotes a healthy complexion and hair, increased energy, overall lower weight.
Cancer: Allium vegetables have been studied extensively in relation to cancer, especially stomach, and colorectal cancers. Their beneficial and preventative effects are likely due in part to their rich organosulfur compounds. Although the exact mechanism by which these compounds inhibit cancer is unknown, possible hypothesis include the inhibition of tumor growth and mutagenesis and prevention of free radical formation.
Onions are also a source of the strong antioxidant vitamin C that helps to combat the formation of free radicals known to cause cancer.
Colon cancer: High fiber intakes from all fruits and vegetables are associated with a lowered risk of colorectal cancer.
Prostate cancer: In a study published by the Journal of the National Cancer Institute, researchers used a population-based, case-controlled study to investigate the relationship between allium vegetable intake and prostate cancer. They found that men with the highest intake of allium vegetables had the lowest risk for prostate cancer.
Esophageal and stomach cancer: Frequent intake of allium vegetables has been inversely related with the risk of esophageal and stomach cancer. Several survey-based human studies have demonstrated the potential protective effects of consuming alliums, as well as reports of tumor inhibition following administration of allium compounds in experimental animals.
Sleep and mood: Folate, found in onions, may help with depression by preventing an excess of homocysteine from forming in the body, which can prevent blood and other nutrients from reaching the brain. Excess homocysteine interferes with the production of the feel-good hormones serotonin, dopamine, and norepinephrine, which regulate not only mood but also sleep and appetite as well.
Skin and hair: Adequate intake of vitamin C is needed for the building and maintenance of collagen, which provides structure to skin and hair.
How to incorporate more onions into your diet
There’s research evidence for including at least one serving of an allium vegetable—such as onions—in your meal plan every day.
When onion is your allium vegetable of choice, try to consume at least one-half of a medium onion on that day, and use this guideline to adjust your recipes accordingly. For example, if you are following a recipe that yields 4 servings, include at least 2 medium onions in the recipe so that each of your 4 servings will contain at least one half medium onion.
