Onions are a good source of potassium and manganese, which increase bone density and reduce the risk of blood clots. In addition, they contain antioxidants that prevent inflammation and limit damage caused by free radicals. They are a good source of vitamin B6, folate and iron, which help boost energy levels and strengthen the immune system.
Good source of Vitamin C
Onions are a good source of vitamin C, an important nutrient that supports immunity, collagen production, and tissue repair, as well as B vitamins like folate and vitamin B6, which are essential for metabolism, red blood cell production, and nerve function.
Good Source of Folate
Onions are a good source of folate, a B vitamin essential for good health. Not only can it help prevent birth defects like spina bifida, it can also reduce the risk of heart disease, some cancers, and cognitive impairment, says Debje, who recommends getting enough folic acid every day. "Eating foods high in folate, like eggs and beef liver," she suggests, can help you meet the recommended daily intake.
Good Source of Chromium
Onions are a good source of chromium, a trace mineral that helps regulate blood sugar levels. Additionally, it's known to lower high cholesterol and lower high blood pressure.
