Patients on low salt diets are usually allowed to eat:

Patients on low salt diets are typically encouraged to consume foods that are naturally low in sodium or do not contain added salt. Raisins fit this categorization as they are dried fruit with minimal sodium content. They provide a healthy source of carbohydrates and essential nutrients without adding significant salt to the diet, making them a suitable snack for individuals needing to restrict their sodium intake.

In contrast, other options are often high in sodium. Potato chips usually contain salt for flavor and can contribute to excessive sodium intake. Cured meats, such as bacon or deli meats, are cured using salt, making them generally unsuitable for low salt diets. Canned soups frequently contain high levels of sodium as preservatives and flavor enhancers, which counteracts the purpose of a low-salt diet. Therefore, among the given choices, raisins are the most appropriate option for individuals following a low salt diet.
