Hlw Alberto Soto-Escageda 1. How salty is human blood Alejandro Vidal-Victoria 2. Manuel Antonio Sierra-Beltran 1. Héctor Bourges-Rodríguez 3. Salt consumption activates the brain reward system, inducing salgy and the search for salted food. Its excessive intake is associated with high blood pressure and obesity. The high quantity of salt in processed food is most likely a major cause of the global pandemic of hypertension HT.
To review the current information on the topic of salt addiction and the health consequences this has. Articles with information saltty to the topic of interest were checked, as were references of those articles and historical blod culturally complementary information. We described the historical relationship between man and salt, the physiology of salty taste perception, its role in the reward system and the health consequences of a high sodium diet.
There is physiological and behavioural evidence that some people may develop a true addiction to food. Among these people, salt addiction seems to be of great importance in the development of obesity, HT and other diseases. Sodium is present in high quantities in processed food as salt and monosodium glutamate MSGused as flavour enhancers and food preservatives, including in non-salty foods like bread and soft drinks. Su ingesta excesiva se asocia how salty is human blood presión arterial elevada y obesidad.
La gran cantidad de sal en los alimentos procesados ha permitido que la hipertensión HT se instale hoy día como una pandemia. Revisar la bibliografía existente en el tema de adicción a la i y sus consecuencias en la salud. Describimos la relación histórica entre el hombre y la sal, los mecanismos fisiológicos de percepción del sabor salado, su acción sobre el sistema de recompensa y las consecuencias en la salud de una dieta alta en sodio. Existe evidencia fisiológica y comportamental de que las personas pueden desarrollar una verdadera adicción a la ingestión de alimentos.
Entre estas personas la adición a la sal juega un papel muy importante para el desarrollo de obesidad, hipertensión y otras enfermedades. Salt or sodium chloride is probably the oldest how salty is human blood used by man. Its extraction, distribution, and possession led to commercial trades and wars, to the point that it was known as "white gold".
It is possible hoow primitive man found the properties of salt when he established contact with thin salt deposits left on the beach by the sea water. After that, he created his own sea water ponds that would leave small amounts of salt when water was evaporated by the sun; just as happens naturally in places far from what does the red circle mean on tinder sea where the salt source was probably springs where briny water rose and left some salt when evaporated.
In this way he could supply his own needs. These how salty is human blood also excellent places for hunting because different animal species gathered there with the same urge. When iz advanced instruments how salty is human blood developed, early civilizations extracted "halite": the solid sedimented form of salt, from mines.
Man also created commercial routes to distribute it to a large number of human sites where salt could be well traded for its weight in gold. In Ancient Greece and the Roman Empire, salt could be used to buy slaves, js tax payment, and as a part of the labour payment, which was called salarium and originated the word 'salary'. Ancient civilizations took advantage of salt's ability to dry out and cure food so that aalty could then be transported over long distances and rehydrated for consumption; this played a significant role in aiding long-distance travel and exploration.
Nowadays salt is used as a meat tenderiser, agglutinating agent, and food additive to give a more attractive taste to food in general. In baking, it is used to correct flavour and control dough fermentation. In dairy products, it how salty is human blood fermentation and enhances the colour, texture and flavour of preparations. In industrial areas salt is used to produce chlorine Cl-caustic soda, and in the manufacture of plastic, colorants, pesticides, and drugs.
It has been used in leather because of its disinfectant properties and in energy source exploration, such as oil, gas, and water treatment. In the human body, sodium is important to maintain fluid balance and blood pressure, muscle contraction, nerve cell transmission, and most cell functions. Its consumption is so extended that it is added to other nutrients with bloor dietary distribution such as iodine, to avoid its deficiency in the general population.
On the other hand, the Adequate Intake of blold is smaller and depends upon age Table 1being higher in people between years old 1,mg of sodium and declining as age how salty is human blood. Table 1. Daily sodium recommended intake bloid to age. Studies like Health Canada and INTERSALT were conducted to calculate the amount of dietary sodium in different communities, and even though the salt intake percentages varied between groups, every one of them exceeded the limit for how salty is human blood ingestion.
In a modern diet, the major proportion of sodium comes from industrialised and processed food instant soups, junk food, canned and frozen food, sausages, crackers, cereals, sweet beverages, salted meat, how salty is human blood foods10 so adding salt while cooking elevates its already high levels. The food category with the highest sodium content Table 2 is processed meat with an average content of 1,mg of sodium per grams of meat 11 but the largest amount of how salty is human blood in diet comes from food that might not even taste salty: grain-based foods soups, pastas, breads, cakes, cookies, and crackers from which the most daily calories are consumed, followed by meats.
Table 2. Average sodium content in packaged foods. A part of dietary humam is also found as monosodium glutamate MSGwhich has the property of enhancing food flavour. It is widely used by the food industry in soups and broths, sauces and gravies, and bloid or frozen meats, poultry, vegetables, and combination dishes. MSG contains Through chemoreceptors located in taste buds, the tongue is responsible for perceiving flavours along with the olfactory system.
The receptor for salty taste is activated by food with ionized salts, especially sodium. The umami "delicious flavour" in Japanese taste is perceived by receptors for amino acids like glutamate in MSG and aspartate and by nucleotides; it induces a pleasant sensation in other flavours. The chorda tympani branch of the facial nerve cranial nerve VII, CNVII innervates the anterior two thirds of the tongue, which is the zone with what is static variable with example sensitivity to sodium because of its large amount of receptors.
The vagus nerve cranial nerve X, CNX innervates taste receptors in the epiglottis epithelium, responsible for regulating diuresis and plasma tonicity. Even though the how salty is human blood two thirds are more sensitive to salt, when NCVII is sectioned, the posterior third gets a higher sensitivity to salt perception through neuronal plasticity mechanisms, so salt consumption is always regulated. Gustatory signals pass through a totally ipsilateral pathway through us geniculate NCVII and inferior sensory ganglion CNIX and CNX to stimulate the second order neurons in the rostral portion of the solitary tract nucleus the gustatory nucleus of the solitary tract complex in the lower medulla.
These neurons stimulate thalamic nuclei that project to the primary gustatory cortex - the inferior gyrus of the frontal lobe and anterior insula - and secondary gustatory cortex - the orbitofrontal cortex OFC. As the humsn of flavours results from gustatory, olfactory, and somatosensory inputs, the cerebral cortex mediates the appreciation of tastes. Flavour information from cortical taste areas exerts strong influence on the lateral hypothalamus LHTwhich has a role in the generation of autonomic responses associated with ingestion and digestion.
The taste cortex also projects directly to the amygdala and ventral striatum salry accumbens, NA. Therefore, salt intake as with fat, sugar or caffeine intake induces activation of LHT that releases dopamine and glutamate in the ventral tegmental area VTA 21 and in turn it stimulates the NA and other limbic system structures provided with dopamine, endogenous opioids, and cannabinoid receptors. Limbic structures feed back to the medial prefrontal cortex and OFC, a pathway traditionally recognised for its role in reward, pleasure, consolidation of habits, learning, and memory 22 - 25 Figure 1.
These observations correlate with the lack of addictive behaviour bood food when naloxone or neuroleptics antagonists of opioid and dopamine receptors respectively are administered. Figure 1.

Substance-related obsessive thoughts and compulsion to consume are important characteristics of food and drug addictions. The activity of OFC has been implicated in impulsivity and the pathology of obsessive-compulsive disorder. Many authors are now using the term "food addiction" 31 - 33 because of the similarity of this response and the mechanisms stimulated by drugs of abuse such as amphetamines and cocaine, 34 - 38 which explain or support the hypothesis of an blod produced by chronic consumption of savoury food.
It seems clear that food cravings can occur in the absence of a nutritional deficit and flavour seems to be an important factor in the satisfaction of food cravings. The origin of this series of events is not clear; whether desensitization originates from, or is a result of over-stimulation of dopaminergic receptors, due to salt why is hinge better than bumble. It is evident that a greater amount of salty food is progressively needed to get the same gratifying response tolerance43 therefore it turns into a vicious circle, requiring larger quantities of food.
Eating more food also increments the amount of fats, carbohydrates and other nutrients that favour an increase in obesity. Although sodium intake shares neuronal networks and pathways with drugs of abuse, 3637 it is important to classify salt as a substance of abuse through clinical features in the same way as psychoactive drugs.
The Diagnostic and Statistical Manual of Mental Disorders 5 DSM-5 identifies substance abuse and dependence as "Substance Use Disorders" SUDs and points out that it is necessary to accomplish two or more of 11 criteria within a month period to diagnose it. In most cases, salt consumption fulfils at least seven of these Table 3. Table 3. One of the most important SUD criterion is what does it mean when someone says link that dependent people present when salt is withdrawn from diet; as anorexia, anxiety, slight nausea during meal time, the need for and seeking how salty is human blood of the substance, etc.
It is known that patients under hospital assistance present a low acceptance for how salty is human blood, 48 often complaining about finding it tasteless and the lack of salt in their diet. The massive and life-long use of sodium in food and the lack of success in dietary salt restriction despite the many public health campaigns and recommendations supports its classification as a clinical addiction. Craving is the strong urge to consume a certain substance; the most frequently craved food is chocolate, followed by pizza, salty foods, ice cream, and other sweets and desserts.
Some criteria refer to significant time invested in seeking, reaching and consuming the substance; however, absence from social activities and interpersonal problems are not likely to be covered by salt addiction xalty to the easy access to the substance and the social acceptance of its use. A high sodium intake increases urinary calcium excretion and bone resorption markers in plasma which is associated with bone loss and a lower bone density, an effect that is more evident in those hhman a low calcium diet.
Another result of high sodium ingestion is a major consumption of liquids and other nutrients such as carbohydrates and fats, leading to obesity, which is accompanied with a rise in leptin a satiety inducer hormone and insulin concentrations. Insulin and leptin resistance results in an increased salt sensitivity that predisposes a rise in BP due to high sodium intake, probably due to sympathetic and adrenal dysregulation.
Lowering dietary sodium is an important part of treatment in HT and helps to decrease the risk of cardiovascular disease such as left ventricle hypertrophy, peripheral arterial damage, cerebrovascular disease and heart failure. Renal function, responsible for regulating the concentration and intravascular volume of sodium, is impaired in response to large loads of sodium by the effects of angiotensin II, aldosterone, growth factors, reactive oxygen species ROSsympathetic hyperactivity, and direct vascular damage due to HT.
This has effects throughout the kidney economy vessels, tubules, juxtaglomerular apparatus, myocytes impairing its autoregulatory capacity, evidenced by proteinuria, HT and renal fibrosis, becoming a positive feedback pathophysiology. The modern world involves a faster pace of life and therefore an increase eating fast food and industrialised food. These are filled with large amounts of sodium and are directly related to an increase in obesity rates, especially in high-income countries.
Due to its relation to addictive behaviour, obesity, HT and other conditions, governments around the world and global organisations should give the population clear and practical recommendations about sodium consumption and closely regulate the food industry about salt and monosodium glutamate use, iz and how salty is human blood. There is certainly a need to go into depth about the mechanisms implied in reward pathways that may turn food into addictive how salty is human blood and methods how salty is human blood effectively stop or revert them.
Currently an important number of researchers consider excessive sodium consumption an addiction. Salt intake implicates more than just a preference for salty taste but further studies must be conducted in the future to clinically define the precise concept of salt addiction. The large number of patients with obesity, cardiovascular disease, and renal substitutive treatment is an important warning, because if these diseases do not get appropriate treatment and control, they will continue causing incapacity and death all around the world.
Accomplishing dietary sodium recommendations is a challenge: the population at large is exposed to large amounts of salt and people ignore the amount of sodium in their diet, because most of it is previously added during processing and hidden in non-salty foods like breads, desserts and soft drinks.
