What type of food contains high levels of potassium that may require monitoring for individuals with fluid restrictions?

  1. Fruits

  2. Dairy

  3. Grains

  4. Meat

The correct answer is: Fruits

Fruits are known to be rich sources of potassium, which is an essential mineral that plays a crucial role in maintaining proper muscle function, nerve function, and fluid balance in the body. For individuals who are on fluid restrictions, such as those with certain kidney conditions, heart failure, or other chronic illnesses, monitoring potassium intake becomes essential. Many fruits, especially those like bananas, oranges, melons, and avocados, can contain significant amounts of potassium. High potassium levels can lead to hyperkalemia, a condition that can have serious health implications, particularly for those whose kidneys may be less effective at filtering potassium from the bloodstream. In contrast, while dairy, grains, and meat also contain potassium, the levels often found in fruits tend to be higher and can contribute significantly to daily dietary potassium. Therefore, it's important to monitor fruit intake carefully to prevent elevating potassium levels beyond what is manageable for individuals with specific health considerations.
