Lesser-known fruit lowers blood pressure, chronic inflammation and ageing issues

A new study suggests that pomegranate extract might be an unexpectedly potent ally in the fight against inflammation and hypertension, particularly as we age. Published in the journal, the research indicates that people over 55 could find pomegranate extract particularly beneficial.

The researchers commented: "Pomegranate extract can lower inflammatory markers and blood pressure, which can be high in both normal-weight and overweight older adults. Making it a cost-effective measure to promote healthy ageing."

In the study, 86 participants were divided into two groups; one received a placebo while the other was given two capsules of pomegranate extract each day. This amounted to roughly 740mg of extract daily, with the cost of average pomegranate extract tablets being about 22p each.

At the beginning of the study, all participants had various levels of inflammatory markers but were generally healthy without any diagnosed diseases. Despite this, many showed risk factors for cardiometabolic conditions, such as high cholesterol and blood pressure.

Out of the original group, 76 finished the study after 12 weeks. Those who took the pomegranate extract every day experienced a significant reduction in these risk factors.

One of the most significant findings was a decrease in blood pressure, which on average fell between 3mm Hg and 5.2mm Hg. Although this may not seem overly dramatic, it has been previously established that a 5mm Hg reduction can reduce the risk of "major cardiovascular events" by up to 10%.

The findings could have "significant implications" for how older patients with hypertension are managed and the lifestyle changes they are advised to make.

However, before these recommendations can be put into practice, researchers caution that more studies are needed to understand the link between pomegranate extract and the cardiometabolic system, particularly given the small sample size in this study.

The impact of pomegranate on the cardiovascular system is not a new discovery. The fruit is rich in polyphenols, which have been thought to prevent cardiovascular disease in the past.

This compound possesses anti-ageing, antioxidant and anti-inflammatory properties that can counteract cellular damage. Essentially, it strengthens cells against the normal wear and tear of life, effectively slowing down the ageing process.

The fruit is also relatively sustainable due to its minimal environmental impact and resilience. The plant can withstand drought, grow in various soil types, and has a low water and carbon footprint.
