Feeling Under the Weather? Onions Might Be Your Secret Weapon

Several recent studies have proven that onions have antiviral and antibacterial effects due to their allicin content.

For instance, a 1999 study published in the journal "Planta Medica" discovered that allicin inhibits the growth of various bacteria and viruses. A 2012 study published in the "Journal of Clinical Pathology" determined that vitamin C and selenium, found in onions, are crucial for proper immune function. Research on the propylene acid present in onions suggests that it may help expand airways, easing asthma and cough, as demonstrated in a 2002 study in the "Journal of Allergy and Clinical Immunology".

Moreover, studies have explored quercetin, a flavonoid found in onions, indicating its anti-inflammatory properties.

A study conducted about three years ago found that this compound, also derived from other plants, is known to reduce inflammatory responses in the body and improve responses to allergic conditions. Therefore, these combined properties make onions one of the healthiest ingredients in the kitchen, especially during the winter months when the body is more prone to respiratory and viral infections.
