What is thiamine for a person?
The human body is a very complex mechanism, the functioning of which is largely dependent on the intake of nutrients. All of them are important and necessary, but among them are especially significant. For example, it is thiamine, the lack of which will certainly affect health. Find out how to get such a substance, and how its deficiency manifests itself.
What is thiamine?
Thiamine is the most common name for vitamin B1. It is a crystalline water-soluble substance that collapses upon thermal exposure. Its discovery is closely related to beriberi, which is especially common in eastern countries and manifests itself in the form of muscle weakness or atrophy, nervous disorders, and disorders of the digestive system.
At the beginning of the last century, Casimir Funk succeeded in isolating from rice bran a substance that facilitated the flow of beriberi. Nitrogen was detected in its molecules, so the scientist decided to rank it as a vitamin category.But the chemical formula and name appeared much later. Thiamine is currently part of the medication and comes in the form of injection solutions and tablets. It is also found in some products.
What is thiamine for? Consider its basic functions and useful properties:
- This substance is actively and constantly involved in many metabolic processes occurring in the body. So, it is responsible for maintaining the water-salt balance, ensures the distribution of fats, guarantees the correct consumption of proteins and is a participant in carbohydrate metabolism. It can be argued that sufficient intake of thiamine is a guarantee of normal metabolism and harmonious work of all important body systems.
- Very important vitamin B1, contained in food, for the nervous system. In particular, it provides timely and high-grade conducting of nerve impulses and protection of nerve cells.
- Thiamine helps protect cell membranes from the negative effects of oxidative processes, stopping them.
- Vitamin B1 contributes to a significant increase in brain activity: improves memory and concentration of attention, accelerates thought processes and reactions.
- Thiamine is also necessary for the smooth functioning of the gastrointestinal tract: it stimulates the motility of the digestive organs and normalizes appetite.
- This substance strengthens and protects the heart muscle, preventing the development of diseases such as heart failure, ischemia, and heart attack.
- Thiamine is useful for women, especially in adulthood, as it strengthens bones, nails and hair.
- Vitamin B1 slows down the processes of oxidation and aging of tissues, and also prevents damage to healthy cells.
- The substance takes part in blood formation and provides normal blood supply to all organs and tissues.
- Thiamine minimizes the toxic effects of poisons, tobacco and alcohol.
How much thiamine is needed? The consumption rate for an adult male is about 1.3-2 milligrams. Older people need to receive daily from 1.2 mg to 1.4. Women need about 1.1-1.6 mg, but the need increases by about 0.5 milligram during periods of breastfeeding and pregnancy. The norm for children under one year is 0.3 mg, up to three years - 0.5 milligram, at the age of four to eight years - 0.6.Adolescents should receive about 0.9-1 mg per day.
The need for thiamine can increase with severe mental, emotional or physical stress, with alcohol abuse or strong coffee, and when taking certain drugs (eg diuretics, laxatives).
How to get?
The main sources of vitamin B1 are mostly vegetable products, such as some cereals (oatmeal, brown unpolished rice, millet, buckwheat), legumes (beans, lentils, peas), peanuts, sunflower seeds, pine nuts, spinach, bran and whole grain bread, as well as soy. But thiamine is also present in food of animal origin: in pork and beef, by-products (lungs, liver, heart, stomach), and also in milk.
a lack of
Thiamine deficiency is possible with insufficient intake into the body, for example, with an unbalanced diet, adherence to strict diets. Also, the level of vitamin B1 reduces bad habits (smoking, alcoholism) and intense stress.
Thiamine deficiency is manifested in the following symptoms:
- irritability, increased nervous irritability;
- insomnia, superficial sleep;
- decreased performance, fatigue;
- depression, apathy, depression;
- memory impairment, slower reaction, decreased concentration;
- impaired coordination of movements;
- changes in heart rate or blood pressure levels;
- numbness or tingling of the limbs;
- chills with a stable body temperature or, on the contrary, a feeling of heat;
- muscle weakness, muscle pain;
- reduction of pain threshold (pain sensation even with minor effects);
- digestive disorders: diarrhea or, conversely, constipation.
If you find yourself having several of these symptoms, you should pay a visit to your doctor, who will certainly advise you on the use of preparations based on thiamine. You will also need to revise your diet. The medication is recommended for such diseases and pathologies as circulatory disorders, myocarditis, heart failure, hypertension and some others.
It is important to know: in case of acute and prolonged deficiency of vitamin B1, severe consequences are likely. For example, symptoms of beriberi may begin to develop, such as muscular atrophy,increased heart rate, headache, heart or muscle pain, memory loss, swelling, insomnia, weakness, nervous disorders, changes in gait, lack of appetite, significant weight loss, digestive disorders.
Excess of thiamine
Excess thiamine is extremely rare, since the substance practically does not accumulate in the body, dissolves in fluids and is naturally excreted in the urine. But with a significant overdose (for example, if you exceed the doses of drugs based on vitamin B1), renal failure, anxiety and fear, liver dystrophy, weight loss, insomnia, fever or blood pressure may occur. These symptoms occur with the injection of synthetic drugs, which can also trigger local allergic reactions and even anaphylactic shock.
Thiamine is a useful and necessary substance for the human body, the deficiency of which can cause serious consequences. But it can be obtained from certain products or drugs.
