The bright flavor of onions makes them a staple in classic recipes such as chicken noodle soup to bolognese and salad negus. But onion is not the only thing that gives them superhero status. The nutritional value of onions is their secret superpower. Onions grow in the form of bulbs underground, belonging to the family of allium vegetables, which also include amaranth and garlic (and many health benefits). Yellow onions are the most common varieties grown in the United States, but in most grocery stores, red onions and white onions are also common. People can eat raw, boiled, or dried onions.

Dr. Liu Ruihai, a professor of food science at Cornell University, said that diets rich in fruits and vegetables had been shown to reduce the risk of chronic diseases such as heart disease, cancer, stroke, and diabetes. “As part of a healthy diet, you should eat a variety of fruits and vegetables, including onions,” he said. Dr. Liu said that the phenolic compounds contained in onions act as antioxidants to inhibit the activity of destructive free radicals. According to a study published in the Journal of Food Science and Technology, the outermost layer of onions has the most antioxidants. Also, onions are cheap, convenient vegetables that can help you reach the recommended 9 to 13 servings of vegetables and fruit per day, even if you work very hard, this goal is challenging to achieve.
A study in the Asia-Pacific Journal of Clinical Oncology in 2019 compared 833 patients with colorectal cancer and 833 patients without the disease.

Experts do not fully understand the exact mechanism by which certain compounds in onions inhibit cancer. Some people assume that onions inhibit tumor growth and cell mutations.
