Strawberries lower cholesterol

25.02.2014
A team of volunteers ate half a kilo of strawberries a day for a month to see whether it altered their blood parameters in any way.

At the end of this unusual treatment, their levels of bad cholesterol and triglycerides reduced significantly, according to the analyses conducted by Italian and Spanish scientists.

Several studies had already demonstrated the antioxidant capacity of strawberries, but now researchers from the Università Politecnica delle Marche (UNIVPM, Italy), together with colleagues from the Universities of Salamanca, Granada and Seville (Spain), conducted an analysis that revealed that these fruits also help to reduce cholesterol. The team set up an experiment in which they added 500 g of strawberries to the daily diets of 23 healthy volunteers over a month. They took blood samples before and after this period to compare data.

The results, which are published in the Journal of Nutritional Biochemistry, show that the total amount of cholesterol, the levels of low-density lipoproteins (LDL or bad cholesterol) and the quantity of triglycerides fell to 8.78%, 13.72% and 20.8% respectively. The high-density lipoprotein (HDL or good cholesterol) remained unchanged.

Eating strawberries also improved other parameters such as the general plasma lipid profile, antioxidant biomarkers (such as vitamin C or oxygen radical absorbance capacity), antihemolytic defences and platelet function. All parameters returned to their initial values 15 days after abandoning 'treatment' with strawberries.

As Maurizio Battino, researcher at UNIVPM and Director of the study, tells SINC: "This is the first time a study has been published that supports the protective role of the bioactive compounds in strawberries in tackling recognised markers and risk factors for cardiovascular diseases."

The researcher admits that there is still no direct evidence about which compounds of this fruit are behind their beneficial effects, "but all the signs and epidemiological studies point towards anthocyanins, the vegetable pigments that afford them their red colour."

The research team confirmed in other studies that eating strawberries also protects against ultraviolet radiation, reduces the damage that alcohol can have on the gastric mucosa, strengthens erythrocytes, or red blood cells, and improves the antioxidant capacity of the blood.

In fact, this year they will publish another study in the journal Food Chemistry in which they will demonstrate that consuming strawberries increases the antioxidant function of blood flow, erythrocytes and mononuclear cells.

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.

As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...
