Purple onions, a common vegetable, not only have a unique flavor but are also rich in various nutrients and offer multiple health benefits. Purple onions are abundant in vitamins, minerals, and antioxidants, effectively supplying essential nutrients to the body and enhancing immune function. Compounds in purple onions, such as sulfur-containing substances, can help lower blood pressure and provide certain benefits for individuals with hypertension. Additionally, purple onions are high in dietary fiber, which promotes intestinal motility and helps relieve constipation. The pungent components in purple onions stimulate gastric juice secretion, improve appetite, and aid digestion.
However, despite these numerous benefits, excessive consumption of purple onions may negatively affect health, so it is important to consume them in moderation.
