Research suggests it may help clear arteries and reduce ‘bad’ cholesterol
Research has shown that consuming a specific red drink can help clean your arteries and reduce ‘bad’ cholesterol.
Pomegranate juice, a sharp and colourful drink, isn’t just delicious but also provides numerous health benefits. And it’s an addition that may benefit your diet.
Rich in antioxidants, pomegranate juice is crucial in protecting LDL cholesterol from damage, which may help prevent plaque build-up. An accumulation of plaque in the arteries presents a significant danger as it narrows and stiffens them, restricting blood flow and increasing the risk of serious health problems such as heart attacks and strokes.
Plaque can also rupture, leading to blood clots obstructing blood flow. Researchers suggest that pomegranate may help combat cardiovascular disease through multiple pathways, including:
- reducing oxidative stress
- supporting the synthesis and activity of nitric oxide
- inhibiting the oxidation of potentially harmful LDL (low-density lipoprotein)
What do studies show?
As reported by Surrey Live, research suggests the antioxidants in pomegranates may help the formation of plaque and slow its buildup. According to a study by Michael Aviram, DSc, at the Technion-Israel Institute of Technology, notes these antioxidants may also help fight oxidised cholesterol, which contributes to clogged arteries.
Other research shows the drink can enhance blood circulation. It’s also been shown to prevent arteries from becoming rigid, which is vital in preventing cardiovascular disease.
Some small studies have shown that regularly drinking it can reduce LDL cholesterol levels. While pomegranates are thought to boost heart health, the National Institutes of Health notes research on this fruit is still in its early stages.
The antioxidants found in pomegranates may help reduce inflammation, thereby supporting healthy arteries. A study published in Clinical Nutrition found significant reductions in plaque thickness among patients who consumed pomegranate over the course of a year.
The results indicated people who drank pomegranate juice (pj) experienced up to a 30 per cent reduction in carotid artery thickness. A nine per cent increase was observed in people with a placebo.
The researchers said the maximum benefit was after 12 months of consuming pomegranite juice (PJ). They 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 PJ consumption”. The polyphenols found in pomegranate may be responsible for these benefits.
Polyphenols are the main source of its antioxidant effects. They help improve how the heart’s lining and blood vessels function.
The researchers added that the results of the present study “suggest that pomegranate juice consumption by patients with carotid artery stenosis decreases carotid intimal-media thickness and systolic blood pressure”. They added: “These effects could be related to the potent antioxidant characteristics of pomegranate juice polyphenols.”
A 2017 review published in Pharmacological Research, which analysed eight clinical trials, indicated that pomegranate juice can lower systolic and diastolic blood pressure. This effect persisted regardless of the amount of juice consumed. The authors suggested that incorporating this fruit juice into a heart-healthy diet could be a wise choice.
Although the research appears promising, further studies are required. Some experts say the drink doesn’t have as much of an impact on cholesterol levels. A 2019 review in Complementary Therapies in Medicine analysed 17 different trials but revealed no notable effects on cholesterol.
The researchers said that comparing these trials was challenging, mainly due to their varied designs and inconsistent dosages of pomegranate used.
Why are pomegranates healthy?
Pomegranates contain antioxidants such as tannins, flavonoids, and anthocyanins that help protect cells by fighting free radicals. These compounds may also help reduce and repair DNA damage, which could lower the risk of some cancers.
The fruit may help prevent arterial thickening and plaque accumulation, supporting healthy blood flow and circulation. They may also help lower blood pressure, an important aspect of heart health.
Pomegranates contain compounds that may reduce inflammation, which can benefit people with inflammatory conditions or those looking to lower overall inflammation.
Other benefits include:
- Pomegranates could enhance stamina during workouts and aid in recovery post-exercise.
- They might play a role in preventing bone deterioration.
- Some studies suggest that pomegranates may boost memory and cognitive abilities.
- They are rich in fibre, which supports healthy digestion and gut health.
Important considerations
Pomegranates may help lower blood pressure. However, if you already have low blood pressure or are taking medication for high blood pressure, it’s best to speak with your doctor before adding pomegranate juice to your diet.
This caution also applies to other heart medications and cholesterol-lowering drugs. It’s also worth noting that pomegranates may slow how the liver processes certain medicines, including statins prescribed to lower cholesterol levels.
Additionally, they may affect the blood thinner warfarin, reducing its effectiveness and raising the risk of clot formation. It’s wise to consult a healthcare provider before making pomegranate fruit or juice a regular part of your diet.
In addition, pomegranate juice contains natural sugars, which can increase calorie intake and may offset some of its heart-health benefits, so it should be consumed in moderation. For safety, it’s important to make sure it’s compatible with your current medications and health routine before making it a regular part of your diet.
If you are worried about your health, always seek help from your GP or another trusted medical professional.
