Health Benefits of Onions

Here are some of the common health benefits of onions.

  • Better Oral Health — This may seem odd since onions can cause bad breath, but chewing raw onion is known to improve the strength of the teeth and fight off bacteria which can cause tooth decay. Chewing some raw onion for 2 or 3 minutes could kill most germs in the mouth.
  • Prevents Colon Cancer — A particular plant-derived flavonoid in onions, called quercetin, boosts the immune system while preventing the development of tumors. One study found that combining chemicals found in onions and turmeric reduced both the size and number of precancerous lesions in the human intestinal tract.
  • Anti-Bacterial and Anti-Microbial Ingredients — Sulphides and thiosulfinates help to prevent illnesses such as E. coli, bacillus subtilis and salmonella.
  • Detoxing – Two sulfur-containing amino acids – methionine and cystine – are great for removing heavy metals like mercury, lead, and cadmium from the body. Additionally, vitamin C, which is also in onions, aids in the detoxing process.
  • Cardiovascular Improvement — Onions help to prevent the formation of blood clots, allowing blood to circulate smoothly. Without the clogs and clots in arteries, heart attack and heart disease risks drop. Further, sulfur compounds in onion can improve red blood cells’ cell membrane function and lower cholesterol and triglyceride levels. Quercetin, found in onions, is also known to lower blood pressure, which boosts cardiovascular health. The health benefits of onions are starting to look quite appealing.
  • Osteoporosis – In a 2005 study, researchers found that a compound in onions, GPCS, was able to decrease bone loss in rats, helping to prevent osteoporosis.
