In recent decades, scientists have found that more and more people are facing disturbances of smell and consequently taste because the two senses are closely linked. Although it may seem trivial, these issues are not neglected. The sense of smell plays an important role in our lives, the quality and joy of living, especially that influence the rate of up to 90% capacity to perceive the taste of food. In addition, the smell is essential to protect us from dangers such as fire, a gas leak, the consumption of adulterated food. Did you know? To perceive odors, volatile particles released by substances are inspired through the nostrils and nasal mucosa cells send a signal to the nervous olfactory bulb, an area at the base of the brain responsible for smell. During a cold, because inflammation of the nasal mucosa, the sense of smell is reduced or disappear temporarily. But if you suddenly left without odor or if it returns after six weeks of passing cold is better to go to the doctor because it may be involved a serious question of neural origin.
The disappearance of the smell is called anosmia and partial reduction – hyposmia. The smell, diet and body weight Dr. Kara Hoover, an expert in olfactory development, pollution and other factors warn that harmful environment is ruining people’s ability to perceive odors. At a meeting of the American Association for the Advancement of Science, Dr. Hoover said that ” people with sensory disturbances of smell are prone to obesity because of the preference for foods with intense flavor, often high in unhealthy fats, salt, sugar,” according to The Telegraph. Those with poor olfactory abilities can not detect subtle tastes and aromas of food. For them, odors are less distinct, which causes them to choose food with pronounced taste, which is mostly processed foods full of salt and fat. Instead, people with a very fine sense of smell, which can distinguish various tastes and flavors, has a tendency to have a normal body weight, some research shows. Decreased odor associated with depression and anxiety What other problems can experience the olfactory reduced capacity? Dr. Hoover says that may be at risk of mental health problems such as depression and anxiety. They have a poor quality of life and may even get pleasure from depression due to lack of distinguishing flavor food, and because of the tendency toward isolation, explained Hoover. People who begin to lose their sense of smell develops high levels of anxiety. On the one hand, they are afraid because they do not perceive their own body odor and feel embarrassed because of this, more are insecure because they are not able to distinguish the smell of smoke or gas leaks. Why we lose the smell? Besides pollution and unhealthy diet, there are other factors that can lead to temporary or permanent loss of smell in modern society.
1. Excess detergents and cleaning products In modern families, hygiene obsession calls and frequent use of excessive aggressive cleaning products, such as chlorine. Consequences? Especially in unventilated spaces (bathroom without window), chlorine emits toxic particles that affect the sensory cells of the nasal mucosa. They are very exposed to loss of smell and those working in the chemical industry, which uses acids, solvents, metal dust. 2. Diabetes Diabetic neuropathy, a complication of “diabetes epidemic” involving nerve damage, manifested especially in the hands and feet (pain, numbness, tingling), but sometimes it can affect the nerves responsible for transmitting the impulse to the olfactory bulb. 3. Pregnancy Hormonal changes in the second and third trimester of pregnancy increase the blood flow, including in small blood vessels in the nasal mucosa. Thus, the lining becomes inflamed and blocks the activity of cells responsible for smell. About 30% of pregnant women with a decline in terms of smell or loss. 4. Antihypertensive drugs Some of the most prescribed treatments at present, antihypertensive drugs have numerous adverse effects, including reduction of odor. If you take such pills, ask your doctor about the deterioration of the sense of smell. 5. Nasal decongestants If respiratory virus diseases, reduction of smell is often associated with nasal obstruction, which is one of the most striking manifestations of colds. For this reason, many people are tempted to use nasal decongestion annate. Only that these products are used in an excess lot worse.
Nasal decongestants work so well that patients use them continuously and thus entering a vicious circle, warns Dr. David Vernick, quoted by the New York Times. The doctor says that decongestants addictive and used long term may lead to atrophy of the nasal mucosa. 6. Dental Abscess Untreated dental infections can spread to the sinuses, can cause inflammation, pain, fever and weakening smell. 7. Aging As sight and hearing deteriorates with age, and the weakening of smell is a sign of aging. A quarter of people over 60 years is facing deterioration smell, and after 80 years, the percentage reaches 60%. That’s because as we age, the number of fibers in the olfactory bulb starts to decrease. 8. Nasal Polyps Adenoids or polyps are obstacles to airflow and hence the odor. This is a cause reversible after removal of polyps, the smell can be improved. 9. Brain damage Lesions in the brain, moderate to severe, especially if they occur in the frontal region can affect nerve fibers that connect the nose to the brain. These fibers are quite delicate, and injuries may impact on them. On the other hand, severe neurological diseases such as stroke, Alzheimer’s disease, Parkinson’s disease, which causes damage to the nerve responsible for the odor, are also causes of deterioration of the sense of smell. Unfortunately, in such cases, losses are irreversible.
10. Lack of vitamin B12 The most important function of vitamin B12 is red blood cell production, but this vitamin plays a key role in the perception of smell. Found in foods like eggs and meat, vitamin B12 is not easily assimilated by the small intestine. B12 deficiency often occurs in the intestinal flora imbalances. 11. The lack of zinc Zinc, an essential mineral, is needed to produce an enzyme called carbonic anihidrază. This enzyme plays an important role in the normal sense of smell and taste. Therefore, a fall of these senses is one of the classic signs of zinc deficiency. If you are in this situation, it is good to include in the diet more sources of zinc: peas, asparagus, Brussels sprouts, pumpkin, seafood, pumpkin seeds raw, avocados, blackberries, figs, berries, pomegranates. A natural source of zinc is Oyster Forte from Zenith, a 100% natural dietary supplement with powdered oyster meat.
