Why onions could be your gut's best friend and more

Onions belong to the Allium family, alongside garlic, leeks and chives. They are packed with nutrients and compounds that offer a range of health benefits. Research suggests they may support digestion, heart health and even cancer prevention. A medium onion contains around 45 calories and 11 grams of carbohydrates. It also provides 12 milligrams of vitamin C, covering 20% of the daily requirement. This vitamin boosts the immune system and acts as a powerful antioxidant.

Onions are rich in prebiotics and fibre, which help maintain a healthy gut. They contain over 25 different flavonoids, including quercetin, known for its heart-protective and antibacterial effects. Another key compound, organosulfur, has shown promise in lab studies for slowing the growth of cancer cells.

A 2016 study found that drinking 3 ounces of onion juice daily for eight weeks could reduce bone loss and improve bone strength. Additionally, a 2019 study revealed that eating around 35 pounds of onions and other allium vegetables yearly might lower the risk of colorectal cancer by nearly 80%. The health benefits of onions are backed by scientific research. Their high levels of vitamins, flavonoids and organosulfur compounds make them a valuable addition to a balanced diet. Regular consumption may contribute to better digestion, stronger bones and a reduced risk of certain diseases.
