Onion

Onions have been used as food since ancient times. They are documented to have been eaten in Egypt around 3,000 BC. They have antimicrobial properties that are effective against salmonella and E. coli. They are anti-allergenic due to the quercetin content, which is especially potent because of being absorbed quickly into the lining of the intestine. It also remains longer in the body than the quercetin from other foods.
