Similar Assertions

For people with high blood pressure, eating more potassium-rich foods leads to higher potassium levels in their bodies after a year, as measured by food records and urine tests.

87%

People with controlled high blood pressure who ate more potassium-rich foods experienced fewer side effects or discomfort after a year compared to those who kept their usual diet.

Even if you eat a lot more or a lot less salt for a week, your body still pees out about the same amount of potassium — your kidneys handle potassium on their own, not by following how much salt you eat.

83%

Even if you eat a lot more or a lot less salt for a week, your body still pees out about the same amount of potassium — your kidneys keep potassium steady no matter how much salt you consume.
