Introduction
For most patients with the common cold, eating onions in moderation can be beneficial. Onions are rich in vitamins, minerals, and trace elements, which can help meet patients' nutritional and energy needs and aid in relieving symptoms. Meanwhile, the volatile sulfur compounds in onions can help alleviate nasal congestion, while vitamin C and antioxidant substances can enhance immunity and promote recovery from the common cold.
Generally, people with a cold can eat onions, but in moderation. Details are as follows:
Onions contain abundant vitamin C, minerals, sulfides, and other components, which have certain antioxidant and anti-inflammatory effects. For individuals with common colds, especially those with good physical condition and no specific contraindications, moderate consumption of onions may help enhance immunity and alleviate cold symptoms. Nutrients in onions may also help relieve symptoms such as coughing and sore throat.
However, onions contain irritating substances, and excessive consumption may lead to abdominal pain. Some cold patients may experience indigestion, and eating large amounts of onions may cause bloating. If the patient has fever, sore throat, or other symptoms, it is not recommended to consume onions. Additionally, individuals allergic to onions should avoid consuming them.
In daily life, it is recommended that cold patients maintain adequate rest and drink plenty of water, which helps improve the body's resistance and accelerate the recovery process.
