Carrot juice may support a healthier heart

Carrot juice is rich in potassium, vitamin C and vitamin A, and may help reduce some risk factors linked to heart disease.

According to a Healthline report, potassium plays an important role in regulating blood pressure. Studies suggest that diets rich in potassium may help prevent high blood pressure and stroke.

The antioxidants in carrot juice may also support heart health. A three-month study of 17 adults with high cholesterol and triglyceride levels found that drinking two cups, or 480ml, of carrot juice daily significantly increased blood antioxidants and reduced the oxidation of blood fats, a process linked to heart disease.

A 2024 study found that juices rich in vitamins A and E improved blood fat and antioxidant levels and helped blood flow through the blood vessels. Higher levels of vitamins A, E and C have also been linked with a lower risk of death from heart disease.

Carrot juice may help regulate blood pressure because its potassium content can help balance sodium levels and relax blood vessel walls, reducing strain on the heart. Some studies suggest that daily intake may lower systolic blood pressure.

The juice is also rich in carotenoids, including beta-carotene, and vitamin C. These antioxidants help neutralise free radicals that can cause oxidative damage to blood vessels, a factor linked with heart disease and plaque build-up.

Research has also linked higher levels of alpha- and beta-carotene in the blood with a lower risk of atherosclerosis. Some studies suggest that antioxidants and soluble fibre in carrots may help reduce LDL, or bad cholesterol, and triglycerides, although evidence in humans is still developing.

Moderation remains important. About one cup, or 240ml, a day is generally advised. Drinking too much may cause the skin to turn yellow or orange, a condition known as carotenemia.

Carrot juice also contains natural sugars and has less fibre than whole carrots, which may cause blood sugar to rise more quickly. People with diabetes should therefore monitor their intake.

Anyone considering major dietary changes should consult a doctor, particularly people taking blood-thinning or blood-pressure medicines. The vitamin K or potassium content may interact with some treatments.
