The research was carried out jointly by the World Health Organization's Collaborating Centre for Nutrition, based at the University of Warwick and University Hospital in Coventry, UK, and the European Society of Hypertension Excellence Centre in Hypertension based at the Department of Clinical and Experimental Medicine, Federico II University Medical School in Naples, Italy.
The study looked at the relationship between the level of habitual dietary salt intake and the occurrence of stroke and cardiovascular disease by reviewing 13 prospective studies from the UK, Japan, USA, The Netherlands, Finland and China, including more than 170,000 participants, followed up for 3.5 to 19 years, who experienced nearly 11,000 vascular events.
The study provides unequivocal evidence of the direct link between high dietary salt intake and increased risk of stroke and cardiovascular disease. A 5 g lower daily salt intake would reduce stroke by 23% and total cardiovascular disease by 17%, thus averting 1.25 million fatal and non-fatal strokes, and almost 3 million vascular events worldwide each year. The effect is greater, the larger the difference in salt intake and increases with time.
Professor Francesco Cappuccio, Head of the World Health Organisation Collaboration Centre at Warwick Medical School said: "We have seen reductions in the salt content of several food items, due to the collaboration between governments, public health bodies and sectors of the industry on a voluntary basis. However, the progress towards the recommended targets has been slow. For population salt intake to approach the WHO targets within a reasonable time, a regulatory approach is necessary, in addition to health promotion campaigns, to reduce the burden of avoidable death, disability and associated costs to individuals and society caused by unacceptable high levels of salt in our diet".
"Habitual salt intake in most adult populations around the world exceeds 10 g per day", says Professor Pasquale Strazzullo, one of the senior authors, "and the World Health Organization recommends that daily intake should not exceed 5 grams. Our study supports current recommendations to reduce substantially salt intake worldwide to avoid unnecessary strokes and other cardiovascular events".
Cardiovascular disease is the first cause of death and disability in the world among people aged over 60 years and the second one among those 15 to 59 years old.
According to the World Health Organization, 62% of all strokes and 49% of coronary heart disease events are attributable to high blood pressure.
There is a direct causal relationship between levels of dietary salt intake and levels of blood pressure.
Most of the salt we eat comes from that added to food in the manufacturing process by industry, caterers and food producers.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
