National Salt Awareness Week – March 4-11, 2025

National Salt Awareness Week takes place in the U.K. from March 4 to March 11. Salt is arguably the most common and essential seasoning in the world. It is even referred to as the taste or flavor of life. But, like most things, too much (or too little) of this fine seasoning can make you sick. This is why it is important to monitor your salt intake and adjust it accordingly. You’ll be amazed at how many health problems you could avoid by sticking to the recommended daily salt intake.

History of National Salt Awareness Week

Since long before recorded history, salt has existed and been an element of human and animal diets. Around 6050 B.C., the first mention of salt was made. Salt was recognized as a valuable product during this time, and it was traded between the Phoenicians and their Mediterranean kingdom. This rich commodity was also employed by the Egyptians in religious offerings and to preserve their mummies.

In the 6th century, the exchange rate of salt became equal to gold. This was because salt at the time was a lot rarer and mainly gotten from salt mines. Thankfully, in around 2700 B.C., the “Peng-Tzao-Kan-Mu” (perhaps the earliest study on pharmacology) was published in China and a huge part of the writing described over 40 types of salt, as well as detailed methods of salt extraction. From then on, salt production in China increased and became a major source of revenue.

Salt was greatly used in Egyptian and Greek medicine. The Egyptians’ “Ebers Papyrus,” a scroll of medical notes and herbal knowledge dating to around 1600 B.C., describes several salt-based remedies for treating infections and epidemic diseases. The ancient Greeks also discovered that salt aided digestion, treated skin diseases, and, when inhaled, helped manage respiratory diseases. Although more and more people started using salt as medicine, it wasn’t until the 19th century that the healing properties and health effects of salt were properly studied scientifically.

National Salt Awareness Week FAQs

How much salt can we take in a day?

Adults and children 11 years and older should not take more than one teaspoon of salt per day.

Is salt bad for the kidneys?

The kidneys work best when there is a balance of potassium and sodium in the body. A high salt intake will increase the sodium levels in the body, therefore disrupting the balance and putting a strain on the kidneys.

Why does salt raise blood pressure?

When sodium levels in the body are high, the body starts storing more water to ‘flush’ the salt away. The extra water puts more pressure on the heart and narrows blood vessels.
