Whether you’re suffering from oral blisters or painful lesions of pemphigus vulgaris or discomfort from ulcers, eating can be an excruciating event.  A soft food diet for sore mouth will include foods that can easily dissolve with little to no chewing.

What is a soft food diet

A soft food diet is a diet modification consisting of food that is pureed, mashed, ground, and moistened. The best soft food diet for sore mouth will include foods that are easy to chew and swallow. 

This type of diet is optimal for people experiencing discomfort from oral lesions, sores, and ulcers. Soft food eliminates the risk of scraping, jabbing, or biting sore and inflamed tissue. This gives the mouth the opportunity to heal. 

Soft food diet for sore mouth due to pemphigus vulgaris

Pemphigus vulgaris is a rare autoimmune disease that causes painful blisters and lesions on the skin and mucous membranes. Blisters burst easily, leaving open sores. Skin that is affected peels easily when rubbed.  Areas affected include the gums, hard and soft palette, inner cheeks, and throat.

When blisters form in the mouth or throat, it can be difficult to eat or even speak. Oral blisters may make it hard to chew or swallow. Lesions also have an increased risk of getting infected.

Soft foods reduce the risk of injuring lesions from teeth or crunchy foods.   

Foods to eat for pemphigus vulgaris should include anti-inflammatory fruits, vegetables, grains, and proteins. Foods rich in vitamins A, C, E and omega-3 fatty acids can help reduce inflammation.

Soft foods to eat with mouth ulcers

Mouth ulcers are sores or erosions of the soft tissue inside the mouth. There are different types of mouth ulcers including canker sores and oral lichen planus. Recurring ulcers can also be a sign of anemia or vitamin deficiency.  The most common cause is trauma to the mouth.  

Mouth ulcers are characterized by persistent pain and difficulty eating.

Like pemphigus vulgaris, ulcers are prone to injury from hard foods as well as infection. Soft foods rich in vitamins, minerals, and antioxidants will help promote tissue repair and reduce inflammation.
