People with eczema should not eat onions.

Eczema is caused by various internal and external factors, leading to inflammation in the superficial dermis and epidermis. Clinically, the acute lesions primarily consist of vesicular rashes accompanied by itching and a pronounced tendency for exudation. Chronic eczema is primarily characterized by lichenification and is prone to recurrence.

Individuals with eczema should avoid onions because onions are spicy and irritating foods. Consuming onions can exacerbate the symptoms of eczema. During the treatment of eczema, patients should not eat foods that are hot in nature, nor spicy, irritating, or allergenic foods. A mild diet should be maintained, drinking plenty of water, and consuming more vegetables and fruits. Additionally, treatment of eczema involves protecting the skin; using moisturizing creams to nourish the skin and enhance its resistance. While bathing, it’s also important to ensure the water is not too hot and to avoid using alkaline soaps or detergents that could damage the skin’s epidermis.
