Celebrated for its abundance of fruits, vegetables, legumes, and, of course, olive oil, it’s consistently linked to a wealth of health benefits. But beyond the golden liquid, a humble, ofen overlooked ingredient plays a crucial role in this culinary tradition: the onion.
More than just a flavor base, onions are a nutritional powerhouse, providing protein, Vitamin C, and essential minerals like iron, calcium, and potassium. Tho, it’s a specific compound within the onion that truly sets it apart – quercetin.

However, its presence in onions makes this readily available vegetable a convenient source of this vital compound.
Research suggests quercetin can definitely help combat oxidative damage and slow down aging, reduce the risk of inflammatory diseases, and even benefit cognitive function. Its antihistamine properties may also offer relief for those suffering from allergies or infections.
