Beetroot juice can help people with coronary artery disease
A daily glass of beetroot juice could have a positive impact on the health of people with coronary artery disease and reduce the risk of heart attack.
As the blood vessels supplying the heart calcify, they become more and more clogged over time. It is a disease of the coronary arteries. According to the German Heart Foundation, around six million people are affected by the disease in Germany alone. A recent study by Queen Mary University of London has now shown that a daily glass of beetroot juice could reduce inflammation in the bodies of people with coronary artery disease.
“Inflammation is vital to protect the body from injury and infection. However, in people with coronary artery disease, prolonged inflammation can worsen hardening of the arteries and increase the risk of heart attack,” explains Dr. Asad Shabbir, who contributed to the study. Nitric oxide is produced by the body and plays an important role in regulating blood pressure and has an anti-inflammatory effect. People with cardiovascular disease have lower levels of nitric oxide in their blood because the enzyme that produces it is less active in them.
Beetroot juice helps with coronary artery disease
Inorganic nitrate in beet juice has an anti-inflammatory effect, scientists said recently at a British Cardiovascular Society conference. Inorganic nitrate affects the level of nitric oxide – it increases and suppresses inflammation, as scientists show.
“Our research suggests that everyday glasses of beetroot juice are a way to incorporate inorganic nitrates into the diet to counteract harmful inflammation,” concludes Asad Shabbir. In the study, the researchers examined 114 healthy subjects. The typhoid vaccine caused temporary inflammation in the body of 78 participants. 36 subjects received a cream that triggered skin inflammation. Half of the study participants received 140 milliliters of beet juice with a high nitrate content and the other half of beet juice with filtered nitrate.
Further clinical studies are needed
Subjects who received the typhoid vaccine and received high nitrate juice had significantly higher levels of nitric oxide in the blood, urine, and saliva than the group that received nitrate-free juice. Similarly, nitrate-rich juice has caused faster recovery of the endothelial cells that line the inside of blood vessels. They are important for the function of blood vessels, but their normal function is lost when they become inflamed. The rash also healed much faster.
The study had only a few participants and its informative value is therefore limited. In addition, the researchers conducted the study with healthy subjects and not with people with coronary heart disease. Clinical trials with test subjects who have ischemic heart disease are now intended to clarify whether a nitrate-rich diet can be shown to reduce the risk of heart attack.
