Introduction
Salt has been a vital part of human history for thousands of years, playing a crucial role in everything from food preservation to warfare. Its significance is apparent in multiple cultures and civilizations, and its impact on global trade, economy, and society is immeasurable. In this section, we will explore the fascinating history of salt and its influence on human civilization throughout the ages, setting the stage for a deeper understanding of its impact on our world.
The Origins of Salt
The history of salt dates back to ancient civilizations such as the Egyptians, Greeks, and Romans. It was discovered in various ways through different legends and myths, but it is known that these ancient societies used it for various practical purposes such as food preservation, medicinal purposes, and for its religious significance.
The earliest known saltworks were in China around 8000 BCE, where the workers boiled brine in iron pots to extract salt. Salt was also used in trade as a commodity and a currency that was highly valued by merchants and rulers alike. It was so valuable that it was even used to pay Roman soldiers (who were sometimes called “salarium argentum,” or “salt money”).
Ancient societies also believed salt to have mythical and spiritual properties, and it was used in religious ceremonies and offerings. In fact, two of the world’s major religions, Judaism and Islam, both use salt in their practices. Jews dip their bread in salt, while Muslims use it in their holy pilgrimage to Mecca.

—Mark Kurlansky, Salt: A World History
Overall, salt has been an essential ingredient in the history of human civilization, and its value and importance can still be seen today.
Ancient Civilizations’ Usage of Salt
| Civilization | Usage of Salt |
|---|---|
| Ancient Egypt | For embalming dead bodies, preserving food, and as a currency. |
| Ancient Greece | As a trading commodity, to season food, and in religious offerings. |
| Roman Empire | As a currency, to pay soldiers, in trade, and for general food preservation. |
| Chinese Dynasties | For medicinal purposes and as a commodity in trade. The Chinese were the first to use natural gas in salt production. |
Salt and the Roman Empire
Salt played a crucial role in the success and downfall of the Roman Empire. The availability of salt had a direct impact on the economy, military strategies and cultural practices of the Roman Empire. The conquest of Italy by the Roman Empire allowed them control of the largest salt works in the Mediterranean, making Rome the central hub of salt distribution in the empire.
Romans used salt to preserve food, and it became a staple for their soldiers during long campaigns, making salt one of the most critical supplies in the Roman military. The production of salt also became a source of wealth for Roman citizens who owned salt mines and factories.
Salt production was so significant to the Roman Empire that they even built roads to transport salt from the salt mines to the cities. The Via Salaria, for example, was constructed specifically to transport salt from the Sabine Hills to Rome. Salt was also used to pay soldiers, which was referred to as “salarium,” ultimately giving rise to the modern English word “salary.”
The Roman Empire’s fall had a severe impact on salt production and distribution. With the collapse of the Roman Empire, the elaborate infrastructure that supported salt production was abandoned, causing a significant reduction in salt availability. As production and distribution declined, the use of salt in everyday life diminished, which caused long-term effects on the economy and culture of the Western world.
Salt and the Age of Exploration
During the Age of Exploration, salt played a crucial role in maritime trade routes and contributed to the development of the larger global economy. The ability to preserve food with salt for long journeys was essential for sailors and merchants alike. As demand for salt increased, so did the production and trade of this valuable commodity.
Salt was also an important factor in determining which countries would control trade routes and territories. Countries with access to salt reserves and the ability to produce it quickly and efficiently gained a significant advantage in the global market.
One example of salt’s impact on exploration is the Spanish search for a sea route to Asia, which was motivated by the lucrative spice trade and the need for salt. When European explorers arrived in the Americas, they encountered indigenous people who traded salt and used it for medicinal purposes. This changed the way salt was perceived and utilized in Europe and beyond.
“In the early days of European exploration, it was impossible to sustain crews on long journeys without salt. Salt provided a way to preserve food and make it last for months, enabling sailors to travel farther and trade more goods.”
Salt as a Preservative
Since ancient times, salt has been used not only as a flavor enhancer but also as a natural preservative for food. Salt helps to prevent bacterial growth that can cause food spoilage, enabling it to be stored for longer periods without refrigeration.
Food preservation using salt has been a significant contributor to the development of human civilization, allowing for the creation of new culinary traditions and dishes that were previously impossible.
Effects on Culinary Traditions
The use of salt as a preservative has influenced culinary traditions around the world, from salted fish in Scandinavia to salt-cured meats in Italy and Spain. In Asia, soy sauce, made from salted fermented soybeans, has become a staple condiment and seasoning for a variety of dishes.
Contribution to Development of Human Civilization
The ability to store food for long periods of time without spoiling has enabled civilizations to flourish in areas where fresh food is scarce or difficult to obtain. For example, salt cod was a staple in the diets of sailors during the Age of Exploration, providing a reliable source of protein during long sea voyages.
In modern times, the use of salt as a preservative continues to be prevalent in the food industry, although concerns about the health impacts of excessive salt consumption have led to efforts to reduce its use.
Salt and Colonialism
During the colonial era, salt played a crucial role in colonization efforts and the exploitation of natural resources in different parts of the world. Colonial powers relied heavily on salt for preserving food during long voyages, and it became a valuable commodity in trade, used to acquire other goods and resources.
Colonial trade routes were often established to transport salt and other goods back to the home country, leading to the development of new technologies and infrastructure such as ports and ships. The production and distribution of salt were also used to exert control over local populations and to solidify colonial power.
One example of this is the British salt monopoly in India, which allowed them to control the production and sale of salt, leading to widespread protests and civil disobedience, including the famous Salt March led by Mahatma Gandhi in 1930.
The exploitation of natural resources, including salt, during the colonial era had a lasting impact on the countries and regions that were colonized, contributing to economic and social disparities that continue to affect them to this day.
Salt and War
The history of salt has seen it being used in a variety of ways, including as a weapon of war. Throughout history, salt has been used to disrupt the enemy’s food supplies, rendering them unable to fight. In addition to that, salt was also used as a method of punishment, with some ancient societies using the method of salting the earth to leave their enemy’s land barren and useless.
One notable example of salt being used as a weapon dates back to ancient Rome. The Roman army was often paid with rations of salt, known as a salarium, and if supplies were cut off or stolen by enemy forces, it significantly weakened their morale and ability to fight.
Salt was also used in medieval times to poison wells or contaminate food supplies, causing widespread illness and weakened enemies. During World War II, the Nazi regime used salt mines in Poland to hide stolen artwork and gold, illustrating the value of salt as a strategic resource in times of conflict.
“Salt was a weapon as valuable as gold or jewels. Its absence could doom a culture to endless war and starvation.” – Mark Kurlansky, Salt: A World History
Salt and Health
The consumption of salt is an essential part of our daily diet. However, there have been ongoing debates about the recommended intake levels since excessive consumption has been associated with various health implications. According to the American Heart Association (AHA), the average person consumes more than double the recommended amount of sodium, mostly in the form of salt.
Excessive sodium intake has been linked to high blood pressure, which can lead to various health problems like heart disease, stroke, and kidney disease. Studies have shown that reducing salt intake can lead to a decrease in blood pressure, thus reducing the risk of developing hypertension.
“The best way to reduce sodium intake is to limit the consumption of processed and prepackaged foods that are often high in salt.”
The AHA recommends a maximum of 2,300 milligrams of sodium per day, which is equivalent to one teaspoon of salt. However, individuals with pre-existing health conditions, such as hypertension or kidney disease, may require lower intake levels.
In contrast, some studies suggest that low sodium intake levels (
| Food | Salt Content (per 100 grams) |
|---|---|
