Young men consuming an alarming amount of salt

Young Swedish men are consuming at least double the recommended amount of salt according to a study carried out by the Sahlgrenska Academy at the University of Gothenburg and Sahlgrenska University Hospital.

"It's alarming that young Swedish men are consuming so much salt, and something needs to be done about it. We can really only speculate on the consequences of such a high salt intake later on in life, in the form of cardiovascular diseases and stroke," says Lena Hulthén, Professor in Clinical Nutrition at the Sahlgrenska Academy.

The study included almost a hundred men in their twenties. Urine samples from all participants were analysed over a 24-hour period. The participants also answered questions about their eating habits. The urine samples showed that the young men were consuming at least two times the World Health Organisation's recommended daily intake of six grams.

"High salt intake can lead to high blood pressure, but we couldn't detect any connection in our study. High blood pressure doesn't usually develop until a person is in their 30s or 40s, since the kidneys' ability to deal with the excess salt deteriorates with age," says Lena Hulthén.

Salt in food is found largely in ready meals such as pizza and frozen meat hash, but it is also in bread, cheese, meat sandwich fillings, fish products, breakfast cereals and other products produced by the food industry. An earlier Danish study has shown that only a tenth of the salt that we consume comes from our own salt cellars.

"The food industry needs clear regulations on how much salt it is allowed to use if we want to reduce total salt intake. One solution could be to follow Finland's example, where all food packaging has to clearly state the salt content to make it easier for the consumer to select products containing less salt," says Lena Hulthén.

People who consume a lot of salt run a greater risk of developing high blood pressure, which in turn is one of the key causes of heart problems and stroke. The National Food Administration (Livsmedelsverket) recommends that Swedish women consume no more than six grams of salt a day, and Swedish men no more than seven grams, but the authority would ideally like to see us consuming between five and six grams a day. The National Food Administration would also like to see children consuming less salt.

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Tiny implants for cells are functional in vivo

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.

In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
