Citrus fruits
Citrus fruits, such as grapefruit, oranges, and lemons, may significantly reduce blood pressure. They include a number of vitamins, minerals, and plant compounds that may help maintain the health of your heart by lowering risk factors for heart disease including high blood pressure.
A 5-month study including 101 Japanese women found a significant correlation between daily lemon juice consumption combine with walking and decreases in SBP (systolic blood pressure). The result was linked to the citric acid and flavonoid content of lemons. Consuming orange and grapefruit juice has also been linked in studies to lower blood pressure. However, before including this fruit in your diet, consult with your doctor because grapefruit and grapefruit juice might conflict with some common blood pressure-lowering medications.
