What is typically advised for a patient on a low sodium diet?

Advising a patient on a low sodium diet to avoid processed foods is sound guidance because processed foods are often high in sodium content due to added preservatives, flavor enhancers, and other ingredients that can significantly increase the overall salt intake. This is important for managing conditions such as hypertension, heart disease, and other cardiovascular issues, where reducing sodium intake can lead to better health outcomes.

In contrast, while increased intake of dairy products could vary in sodium content depending on the product and type, it does not specifically pertain to sodium reduction. Similarly, cooking with higher amounts of salt directly contradicts the purpose of a low sodium diet, and substituting sugary snacks may not address sodium levels at all. Therefore, emphasizing the avoidance of processed foods is the most effective strategy for someone needing to limit sodium intake.
