Antioxidants and anitibotics
Scallions are very low in calories; 100 g of fresh leaves provide just 31 calories. Nonetheless, they contain many noteworthy flavonoid anti oxidants, plant fiber, minerals, and vitamins that have proven health benefits. Onions are a major source of polyphenols in general, and also of flavonoids (a very important subdivision of polyphenols). They can also vary greatly in their polyphenol and flavonoid content. In general, red onions are higher in total flavonoids than white onions, (with yellow onions falling somewhere in between).
