Why do we need to #SwitchTheSalt?
Why do we need to #SwitchTheSalt?
Almost everyone eats salt and almost everyone eats too much of it. Eating too much salt increases blood pressure, leading to heart attacks, strokes and deaths. Despite the efforts by governments and medical organisations over the last decade to reduce population salt intakes, little progress has been made. This is because people have become accustomed to the taste and dietary habits are hard to change. Salt is also a widely used ingredient in food manufacturing, and progress towards lowering levels in packaged foods has been slow.

What is potassium-enriched salt?
Potassium-enriched salt is a practical and scalable approach to lowering blood pressure and with it, the risk of strokes, heart attacks and death. Salt is made up of 100% sodium and chloride. A potassium-enriched salt, however, has some of the harmful sodium chloride replaced wi
