Salt vs Caen

Informations

Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater, where it is the main mineral constituent. The open ocean has about 35 grams (1.2 oz) of solids per liter of sea water, a salinity of 3.5%. Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation. Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, the Greeks, the Romans, the Byzantines, the Hittites, Egyptians, and the Indians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, and across the Sahara on camel caravans. The scarcity and universal need for salt have led nations to go to war over it and use it to raise tax revenues. Salt is used in religious ceremonies and has other cultural and traditional significance.

Salt is processed from salt mines, and by the evaporation of seawater (sea salt) and mineral-rich spring water in shallow pools. Its major industrial products are caustic soda and chlorine; salt is used in many industrial processes including the manufacture of polyvinyl chloride, plastics, paper pulp and many other products. Of the annual global production of around two hundred million tonnes of salt, about 6% is used for human consumption. Other uses include water conditioning processes, de-icing highways, and agricultural use. Edible salt is sold in forms such as sea salt and table salt which usually contains an anti-caking agent and may be iodised to prevent iodine deficiency. As well as its use in cooking and at the table, salt is present in many processed foods. Sodium is an essential nutrient for human health via its role as an electrolyte and osmotic solute. Excessive salt consumption may increase the risk of cardiovascular diseases, such as hypertension, in children and adults. Such health effects of salt have long been studied. Accordingly, numerous world health associations and experts in developed countries recommend reducing consumption of popular salty foods. The World Health Organization recommends that adults should consume less than 2,000 mg of sodium, equivalent to 5 grams of salt per day.

The city proper has 108,365 inhabitants (as of 2012), while its urban area has 420,000, making Caen the largest city in former Lower Normandy. It is also the third largest municipality in all of Normandy after Le Havre and Rouen and the third largest city proper in Normandy, also after Rouen and Le Havre. The metropolitan area of Caen, in turn, is the second largest in Normandy after that of Rouen, the 21st largest in France. It is located 15 kilometres (9.3 miles) inland from the English Channel, 200 kilometres (120 miles) north-west of Paris, and connected to the south of England by the Caen (Ouistreham) to Portsmouth ferry route.

Caen is located in the centre of its northern region, and it is a centre of political, economic and cultural power. Located a few miles from the coast, the landing beaches, the bustling resorts of Deauville and Cabourg, as well as Norman Switzerland and Pays d'Auge, Caen is often considered the archetype of Normandy. Caen is known for its historical buildings built during the reign of William the Conqueror, who was buried there, and for the Battle for Caen, heavy fighting that took place in and around Caen during the Battle of Normandy in 1944, destroying much of the city. The city has now preserved the memory by erecting a memorial and a museum dedicated to peace, the Mémorial de Caen.
