What are the Benefits of Lemons for High BP?

Several studies have shown that the regular consumption of citrus fruits like lemons, oranges, and grapefruits can help lower blood pressure, along with reducing your risk of developing heart disease. 

Though the exact benefits of lemons and lemon water for high BP are still being studied, the following mechanisms of action have been proposed:

• Has diuretic properties

Lemon water helps improve the balance of electrolytes in your body by eliminating excess fluid through urine. Lemon juice has a decent amount of potassium and very little sodium, and it also promotes the absorption of calcium and magnesium from your diet. All of these minerals are essential in regulating your blood pressure levels.

• Has antioxidant properties

Vitamin C is a potent antioxidant that plays a crucial role in maintaining your heart health. Vitamin C, along with other antioxidants present in lemons like flavonoids, prevents the oxidation of fatty substances in your diet called cholesterol. Cholesterol, when oxidised, can stick to the walls of blood vessels that have been damaged by hypertension. This is known as plaque formation, which can cause your blood vessels to become clogged, stiff, and narrow. 

When blood flows through stiff and narrow arteries, it can further increase your blood pressure. Thus, the antioxidants can prevent further elevations in blood pressure along with the heart diseases associated with it by preventing the oxidation of cholesterol.

What is the Best Way to Consume Lemon for High Blood Pressure Control?

Lemons are a versatile fruit that can be used to boost the flavour profile of beverages, salads, curries, meat, desserts, etc. You can use lemons and lemon juice in the following ways to help lower your blood pressure:

Adding lemon juice or lemon slices to your water can help you stay hydrated by balancing your electrolyte levels. It also helps improve your antioxidant and potassium intake.
