Sweet Onions and Health

Healers through the ages have had great respect for the curative powers of the onion and recent studies have validated these old beliefs.

Onions contain more than one hundred sulfur-containing compounds. These sulfur compounds are what cause the eyes to tear up when cutting onions. One particular sulfur compound has been found to prevent the biochemical chain of events that lead to asthma and respiratory ailments.

Onions are rich in flavonoids which have been shown to deactivate several potent carcinogens and tumor promoters as well as interfere with the growth of estrogen-sensitive cells involved in breast cancer.

Last but not least, an onion a day can raise HDL's (good cholesterol), resulting in lower blood pressure and prevention of blood clots. One-half cup of raw onion has 30 calories; one-half cup of boiled has 45. Onions also contain generous amounts of Vitamin B6, Vitamin B1, and folic acid.
