Everyone needs potassium in their diet, as it maintains the fluid balance in cells, supports muscle contraction, and helps regulate blood pressure. However, people with kidney disease may need to limit their potassium intake, as they can't flush excess from their bodies like healthy people.
A low-potassium diet can be tricky to design, as it occurs naturally in many foods, including fruits.
Lemons and limes are commonly used for flavoring sweet and savory dishes and adding to juices and smoothies. They're highly nutritious, but are they safe for those on a low-potassium diet?
