Question: if you have high blood pressure can you drink grapefruit juice?
Answer: Grapefruit juice and the actual grapefruit can be part of a healthy diet. Grapefruit has vitamin C and potassium—nutrients your body needs to work properly. But it isn't good for you when it affects the way your medicines work, especially if you have high blood pressure or arrhythmia (irregular or abnormal heart beat).
