They are a good source of folic acid
Onions are an excellent source of folic acid, one of the 8 B vitamins needed to convert food (carbohydrates) into fuel (glucose). Folic acid also supports a healthy liver and helps form new cells. Folic acid can help fight depression and can be used as a treatment for people with low blood folate levels (folate deficiency or folate deficiency due to hyperhomocysteinemia). Additionally, it has been known to reduce the risk of heart disease, stroke, and some types of cancer.
They are a good source of quercetin
Onions are an excellent source of quercetin, a flavonoid antioxidant. This helps fight free radicals that damage cells and reduces the chance of developing cancer and other chronic diseases. Another great benefit of onions is their ability to lower cholesterol levels. This is thanks to quercetin, a flavonoid found in onions. Quercetin may also help lower high blood pressure and protect against heart disease risk factors by reducing inflammation.
They are a good source of vitamin C
Onions are an excellent source of vitamin C, an important antioxidant that can reduce oxidative stress in the liver. Additionally, onions boost immunity and reduce inflammation.
They are a good source of potassium
Onions are an excellent source of potassium, which is necessary for normal cell activity, fluid balance and nerve transmission. Additionally, potassium helps control blood pressure and coordinate muscle contractions.
