Onions and Health: A Comprehensive Guide to Their Therapeutic Benefits

Onions are considered to possess high antioxidative properties, effectively eliminating reactive oxygen species, aiding in blood purification, inhibiting cancer cell proliferation, and inducing their natural death (apoptosis), while also mitigating allergic reactions and inflammation. A study conducted in France on women showed that those who consumed more onions and garlic had a lower risk of developing breast cancer. Onions play a significant protective role in preventing atherosclerosis and can be beneficial in preventing and treating conditions like anemia and heavy metal poisoning. Additionally, they help regulate physiological balance and metabolism, promote gastrointestinal peristalsis, and stimulate appetite. Glutathione, a compound found in onions, helps alleviate eye fatigue and blurred vision.

Onions contain two essential phytochemicals: sulfur-containing compounds such as alliin and quercetin (a type of polyphenol). Cooking onions results in a sweeter taste due to the reduction of the pungency caused by alliin when heated, allowing the sweetness to become prominent. Alliin exhibits highly antioxidative properties, effectively eliminating reactive oxygen species.

Moreover, quercetin, present in both onion flesh and brown skin, possesses not only robust antioxidative capabilities but also purifies the blood, inhibits cancer cell proliferation, induces cancer cell apoptosis, and mitigates allergic reactions and inflammation.

Onions have some benefits and effects on maintaining skin health and beauty. The plant compounds present in onions, such as quercetin and alliin, possess powerful antioxidant properties that aid in purifying the blood, inhibiting cancer cell proliferation, inducing natural cell death, and reducing allergic reactions and inflammation. These attributes contribute to improving skin health.
