When people with controlled high blood pressure eat a meal high in potassium, their blood potassium levels go up significantly compared to a low-potassium meal, especially within an hour and two hours after eating.

One hour after eating a low-potassium meal, people with controlled high blood pressure have higher blood sugar levels than after a high-potassium meal, which is a statistically significant difference.

Two hours after eating a high-potassium meal, people with controlled high blood pressure have slightly higher diastolic blood pressure compared to a low-potassium meal, though the difference is small.

One hour after eating a high-potassium meal, people with controlled high blood pressure have higher blood fat levels compared to a low-potassium meal, which is a statistically significant difference.

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.

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.
