New research shows that Artichoke Leaf Extract lowers cholesterol

03.07.2008
Researchers at the University of Reading have found that an over-the-counter Artichoke Leaf Extract (ALE) from the globe artichoke plant can lower cholesterol in otherwise healthy individuals with moderately raised levels.

Cardiovascular diseases are the chief causes of death in the UK, and are associated with raised circulating levels of total cholesterol in the plasma. Once plasma cholesterol reaches a certain level, drugs such as statins are often prescribed to help reduce it.

Intervention before concentrations reaches these levels may help reduce the risk of developing cardiovascular diseases without the need for drugs. This new piece of research has shown that otherwise healthy people with moderately raised plasma cholesterol may be able to lower their levels by taking this herbal supplement.

During the trial, 75 volunteers were given 1280mg (4 capsules) of an ALE, or matched placebo, each day for 12 weeks. ALE consumption resulted in a modest but favourable statistically significant reduction in total plasma cholesterol after the intervention period.

For over 10 years, the relationship between dietary intakes of antioxidant nutrients and a reduced risk of cardiovascular diseases has been recognised and investigated. Antioxidant nutrients include ‘non-essential’ phytochemicals (e.g. flavonoids) as well as ‘essential’ nutrients (e.g. vitamins C, E). Several plant-rich sources of flavonoids, such as fruits and vegetables, tea, red wine, cocoa and olive oil, have been associated with lower risk of cardiovascular diseases, although the exact mechanisms for their protective effects is still not clear. Research has shown that ALEs are rich in various flavonoids.

Globe artichokes have been used traditionally in Europe to improve digestive and urinary tract health. Artichoke leaf extracts (ALEs) are currently used in Germany and Switzerland as a remedy for indigestion, and are available in the UK as over-the-counter food supplements. Various studies have provided an evidence base for their use in conditions such as dyspepsia and irritable bowel syndrome.

Dr Rafe Bundy said “Reducing cholesterol levels can reduce the risk of developing cardiovascular disease. Our research investigated whether ALE could be beneficial to otherwise healthy people who had raised levels of cholesterol but were not yet at a stage where they needed standard medical intervention. ALE may provide another option which people could try over and above a healthy diet in order to help lower plasma cholesterol.”

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
