The Nutritional Powerhouse Behind the Garnish
Green onions, or scallions, are a mild-flavored member of the Allium family, which also includes garlic, onions, and chives. Often used as a fresh topping, they contain a surprising density of beneficial compounds. The green, leafy tops, as well as the white bulbous part, are rich in vitamins, minerals, and phytonutrients that contribute to a healthy body. For example, a single cup of chopped green onions can provide over 200% of your daily recommended intake of Vitamin K. This potent nutrient profile makes them an excellent addition to almost any meal.
Boosts Your Immune System
Green onions are rich in both Vitamin C and Vitamin A, two powerful antioxidants that are essential for a robust immune system. Vitamin C helps protect the body from infections, while Vitamin A is crucial for immune cell development. Flavonoids and sulfur compounds in green onions also contribute to their ability to help your body fight off illness.
Supports Cardiovascular Health
Consuming allium vegetables is linked to a lower risk of heart disease. Antioxidants in green onions, like quercetin, may help lower LDL cholesterol and reduce blood pressure. Their anti-inflammatory effects can also protect heart tissue, and potassium content aids blood pressure regulation.
Enhances Bone Strength
Green onions are a good source of Vitamin K, which is critical for strong bones. Vitamin K helps bind calcium to bones, increasing density and reducing fracture risk, important for preventing osteoporosis.
Aids Digestion and Gut Health
The dietary fiber in green onions supports healthy digestion by preventing constipation and promoting regularity. They also contain prebiotic fibers that nourish beneficial gut bacteria, supporting a healthy microbiome which is important for overall health.
Fights Inflammation and Oxidative Stress
Green onions have anti-inflammatory properties due to bioactive phytonutrients that inhibit inflammatory compounds. Their antioxidants also neutralize free radicals, protecting cells from damage and reducing oxidative stress linked to various health issues, including arthritis.
