'Unclog arteries' with red juice that lowers blood pressure and cholesterol

Research indicates that a red drink might assist in clearing your arteries and addressing other heart-related problems. Pomegranate juice, with its zesty flavour and bright colour, is not just delicious but also packed with health perks thanks to its rich antioxidant levels.

These antioxidants work to shield 'bad' LDL cholesterol from further harm and may help prevent plaque accumulation. Excessive plaque in the arteries poses a serious threat as it narrows and hardens them, restricting blood flow and heightening the risk of major health concerns like heart attacks and strokes.

Plaque can also break apart, resulting in blood clots that block blood flow. Experts propose that pomegranate could be a useful tool in combating cardiovascular disease, especially when combined with a balanced diet, healthy weight, and lifestyle choices.

The fruit and its juice may help lower oxidative stress, boost nitric oxide production, and prevent the oxidation of potentially harmful LDL (low-density lipoprotein) cholesterol. Nitric oxide is beneficial for your body since it plays vital roles in maintaining a healthy cardiovascular system, regulating blood pressure, and improving blood circulation to different organs and tissues. Preventing the oxidation of LDL cholesterol is also beneficial because oxidised LDL can trigger inflammation and plaque formation in the arteries.

What do studies prove?

Research indicates that the antioxidants present in pomegranates may stop plaque buildup in the arteries and may also diminish current deposits. Studies by Michael Aviram, DSc, a biochemistry professor at the Technion-Israel Institute of Technology, show that the antioxidants in pomegranates can successfully counteract oxidised cholesterol, which contributes to arterial blockages.

Further studies indicate that pomegranate juice may improve blood circulation. It has also been found to prevent arteries from hardening, which is crucial for avoiding heart disease. Small studies suggest that regular consumption of pomegranate juice may lower LDL cholesterol levels.

Pomegranates are said to promote heart health, although the National Institutes of Health notes that research on the fruit is still in its early stages. The antioxidants present in pomegranates may help reduce inflammation, which is beneficial for arterial health.

One study showed significant decreases in arterial plaque among participants who consumed pomegranate juice for several months. The findings indicated that those who drank pomegranate juice had up to a 30 per cent reduction in carotid artery thickness, while the control group experienced a nine per cent increase.

The researchers said: "Systolic blood pressure was reduced after one year of pomegranate juice consumption by 12 per cent and was not further reduced along three years of [...] consumption". They added: "These effects could be related to the potent antioxidant characteristics of pomegranate juice polyphenols."

The polyphenols present in pomegranate juice are thought to drive these encouraging outcomes. These polyphenols, praised for their powerful antioxidant qualities, may also enhance the performance of the heart's endothelium and its surrounding blood vessels. The researchers observed that their study's results "suggest that pomegranate juice consumption by patients with carotid artery stenosis decreases carotid intimal-media thickness and systolic blood pressure".

A 2017 analysis in Pharmacological Research, examining eight clinical trials, discovered that pomegranate juice might lower both systolic and diastolic blood pressure, irrespective of the amount consumed. The authors suggested incorporating this juice into a heart-healthy diet as a positive step.

Whilst present research shows promise, further studies are required. Some experts contend that the drink has a minimal influence on cholesterol levels. A 2019 analysis in Complementary Therapies in Medicine, which examined 17 trials, revealed no substantial effect on cholesterol. The researchers highlighted the challenge in comparing these studies owing to their varied approaches and inconsistent pomegranate quantities.

What makes pomegranates good for your health?

Pomegranates are rich in antioxidants such as tannins, flavonoids, and anthocyanins, which combat free radicals and protect cells from harm. These antioxidants may assist in preventing and repairing DNA damage, potentially reducing the risk of cancer. Pomegranates might also help avert artery thickening and plaque accumulation, thereby supporting healthy blood circulation.

They could aid in lowering blood pressure, an essential factor for maintaining heart health. These fruits are packed with compounds that can help reduce inflammation throughout the body. This makes them a great option for individuals with inflammatory conditions or those looking to decrease overall inflammation.

Other advantages include their capacity to enhance stamina during workouts and facilitate recovery after exercise, as well as their potential role in preventing bone loss. Some research also indicates that pomegranates may improve memory and cognitive functions. Furthermore, they are high in fibre, which promotes digestion and gut health.

What do you need to keep in mind?

Although pomegranates may provide various health advantages, if you have low blood pressure or are taking medication for high blood pressure, it is advisable to consult your physician before including pomegranate in your diet. This beverage serves as a supportive option and should not replace prescribed medical treatments for elevated cholesterol or atherosclerosis.

This warning also extends to people on heart-related medications or drugs for cholesterol management. It is important to recognise that pomegranates may hinder the liver's ability to metabolise certain medications, such as statins that are used to lower cholesterol. They might also interfere with the blood-thinning medication warfarin, reducing its effectiveness and raising the risk of clot formation.

It is best to seek guidance from a healthcare professional before making pomegranate fruit or juice a regular part of your diet. Pomegranate juice contains a high amount of sugar, which can lead to increased calorie intake and may negate some of its heart-healthy properties—moderation is essential.

Pomegranate juice has natural sugars. A single cup of 100% pomegranate juice has approximately 31-33 grams of sugar, derived from the fruit rather than added sugars. Pomegranate juice does not contain the fibre present in whole pomegranates, which can lead to a rapid increase in blood sugar levels. It should be consumed with care, particularly by those with diabetes or kidney issues.
