Onions have been shown to have strong antioxidant properties, reduce inflammation and suppress the growth of harmful microorganism.
1. Anti-Microbial Effects
There are many microorganisms in the environment, as well as inside our bodies. Some of them can cause harm.Onion extracts and essential oils may suppress the growth of harmful microorganisms, such as bacteria and yeasts.
2. Blood Sugar Regulation
Diabetes is a common disease, characterized primarily by high blood sugar levels. Animal studies have shown that onions can lower blood sugar levels.This has also been shown in humans. One study in diabetics found that 100 grams of raw onions per day led to a significant reduction in blood sugar levels.
Raw onions may be beneficial in the management of both type 1 and 2 diabetes, but more research is needed.
3. Bone Health
Osteoporosis ("porous" bones) is a common health problem, especially in postmenopausal women. A healthy diet is one of the main preventive measures.Animal studies have shown that onions have protective effects against bone deterioration, and may even increase bone mass.
A very large observational study in women over 50 years of age found that regular onion consumption is linked with increased bone density.
A new controlled trial also showed that intake of selected fruit, herbs and vegetables, including onions, may reduce bone loss in postmenopausal women.
4. Cancer Prevention
Cancer is a common disease, characterized by uncontrolled growth of cells in the body. It is one of the world's leading causes of death.
Observational studies have linked increased consumption of onions to reduced risk of several types of cancers, such as stomach-, breast-, colon- and prostate cancers.
In brief, Onions have antioxidant and anti-inflammatory effects. They may help fight infections, lower blood sugar, improve bone health and reduce the risk of several types of cancers.
