Onions are an inexpensive vegetable that research has shown to have several health benefits.
1. Onions can help protect against heart disease
According to Dr. Victor Gurewich, MD, cardiology professor at Harvard, people who suffer from coronary heart disease or are at risk of heart disease can increase their beneficial HDL cholesterol levels by eating onions. It is important to note that the longer the onions are cooked, the less the effect is.
2. Onions can prevent blood clots
Harvard researcher Robert Flaumenhaft found that rutin, a compound found in many foods, including onions, can act as an anticoagulant and can prevent and treat blood clots, so it is beneficial when high-fat foods such as steaks are cooked with onions.
3. Onions can lower cancer risk
Foods — such as yellow onions, garlic, green onions and leeks — belong to the same family and contain anti-cancer chemicals. Research done in Shandong Province, China – which is an area noted for its high incidence of gastric cancer – found that the more onions consumed, the lower the incidence of gastric cancer.
4. Onions can alleviate asthma
Onions are loaded with anti-inflammatory compounds that help soothe the symptoms of asthma. Onions are also believed to contain an antioxidant that can dilate the bronchi.
5. Onions can lower blood sugar levels
Onions have long been used to treat diabetes because they contain an element similar to tolbutamide, a chemical compound stimulating the synthesis and release of insulin. There have been studies that support this conclusion.
6. Other beneficial effects of onions
Shredded onions can be used to calm nerves and improve sleeplessness. If the symptoms of a cold appear, hot onion soup can make you perspire to break your fever.
