A mechanical soft diet or edentulous diet is a diet that involves foods that are soft, with the goal of reducing or eliminating the need for food. It is recommended for people who have difficulty chewing food, including people with certain types of dysphagia (difficulty swallowing), the loss of many or all teeth, the surgery involving the jaw, the mouth or gastrointestinal tract, and the bread of newly adjusted dental braces. They are mashed, puréed, chopped very small, combined with gravy or gravy, or softened in liquid. In some situations, there are additional restrictions. For example, patients who need to avoid acid reflux, such as those recovering from esophageal surgery for achalasia, are also instructed to stay away from foods that can aggravate reflux, which include ketchup and other tomato products, citrus fruit, chocolate, mint, spicy foods, alcohol, and caffeine. Foods such as tomatoes and blackberries can be restricted because they contain small seeds.
A puréed diet is commonly used for people who have difficulty swallowing, and provides a uniformly smooth consistency. Most of the foods on this diet can be used with a full-liquid diet.
