Five health benefits of onions and their role in longevity

Dr. Natalia Kovalyova, an endocrinologist, stated that onions are a versatile ingredient used in many dishes across global cuisines. Beyond enhancing flavor, onions also boost nutritional value and offer significant health benefits.

According to Kovalyova, as reported by health.mail.ru, onions provide five health benefits that may help promote well-being and longevity. First, onions are rich in antioxidants such as quercetin, a powerful anti-inflammatory compound. Antioxidants help combat oxidative stress caused by free radicals, support skin health, and slow the appearance of aging.

Second, scientific studies have shown that consuming onions may aid those monitoring their weight, with observed reductions in body fat, including subcutaneous and visceral fat.

Third, red, green, and yellow onions contain essential oils with antibacterial properties, effective against bacteria such as Salmonella and Staphylococcus aureus. Phytoncides in fresh, raw onions also inhibit the growth of bacteria and fungi.

Fourth, onions contain inulin, a type of natural soluble dietary fiber that acts as a prebiotic, supporting the growth of beneficial gut bacteria and contributing to digestive health.

Fifth, onions may help regulate blood cholesterol levels by lowering bad cholesterol and increasing good cholesterol, thereby supporting healthy fat metabolism.

Kovalyova noted that people with onion allergies or digestive issues should avoid onions, as they may cause heartburn and worsen symptoms of irritable bowel syndrome.
