Bari vs Salt

Informations

Bari ( BAR-ee, Italian: [ˈbaːri] (listen); Barese: Bare [ˈbæːrə]; Latin: Barium; Ancient Greek: Βάριον, romanized: Bárion) is the capital city of the Metropolitan City of Bari and of the Apulia region, on the Adriatic Sea, in southern Italy. It is the second most important economic centre of mainland Southern Italy after Naples (and the third after Palermo, if Insular Italy is included), a port and university city, as well as the city of Saint Nicholas. The city itself has a population of 320,257 inhabitants, over 116 square kilometres (45 sq mi), while the urban area has 750,000 inhabitants. The metropolitan area has 1.3 million inhabitants. Bari is made up of four different urban sections. To the north is the closely built old town on the peninsula between two modern harbours, with the Basilica of Saint Nicholas, the Cathedral of San Sabino (1035–1171) and the Hohenstaufen Castle built for Frederick II, which is now also a major nightlife district.

To the south is the Murat quarter (erected by Joachim Murat), the modern heart of the city, which is laid out on a rectangular grid-plan with a promenade on the sea and the major shopping district (the via Sparano and via Argiro). Modern residential zones surrounding the centre of Bari were built during the 1960s and 1970s replacing the old suburbs that had developed along roads splaying outwards from gates in the city walls. In addition, the outer suburbs developed rapidly during the 1990s. The city has a redeveloped airport, Karol Wojtyła Airport, with connections to several European cities.

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.
