Improve digestive system

Onions can improve digestive system. If you have digestion problem, then onions can cure it by increasing the release of digestion juices. Onions, like garlic, are members of the Allium family, and both are rich in sulfur containing compounds that are responsible for their pungent odors and for many of their health promoting effects. A wide variety of allyl sulfides are found in onion, including the four major diallyl sulfides: DMS (diallyl monosulfide), DDS (diallyl disulfide), DTS (diallyl trisulfide), and DTTS (diallyl tetrasulfide). Also present are a wide variety of sulfoxides, including (+) S methyl L cysteine sulfoxide (MCSO), (+) S (1 propenyl) L cysteine sulfoxide (PRENCSO), S methyl l cysteine sulfoxide, S propyl l cysteine sulfoxide, and S propenyl l cysteine sulfoxide. Onions are an outstanding source of polyphenols, including the flavonoid polyphenols. Within this flavonoid category, onions are a standout source of quercetin.
