The vitamin-rich layers of onions The vitamin-rich layers of onions

Commonly used as a condiment for different foods, onions are also vegetables that help build bone health.

As nutritionist and dietitian Ana Molina Jiménez explains to the EFE Health agency, the quercetin content of this vegetable strengthens the immune system. Onions also have a high water content and are low in calories (about 100 grams contain approximately 40 calories), and they are high in vitamin C and vitamin K.

While calcium is often associated with being found in dairy products, as Jiménez comments, onions contain 15% of the recommended daily amount of calcium, so eating them helps keep the bones strong and help prevent diseases such as osteoporosis.

Keep in mind

For people who find onions difficult to digest due to colon problems or heartburn, the recommendation is to eat them cooked. People without these sensitivities can eat them raw, as cooking decreases the presence of phytochemicals.
