without increasing number of people, encouraged by the BSE - crisis on meat. Steaks, roast beef and liver are no longer with them on the table. For the vegans, even the whole foods of animal origin - of meat and fish to eggs to dairy products - removed from the diet. Instead, they attack only to fruits, vegetables, grains, nuts or legumes - with good results, as most reporting on more vitality and performance. But does the strict vegetarian diet vitamin
and mineral needs of the body? A legitimate question about the vitamin 8 12, the want of serious health effects entails.
All concerns about deficiencies - mainly by concern for the vitamin - B12,
ago whose deficiency is warned - are in Vegan - appeases books
Overall, experts estimate, nutritional Ren about ten percent of the approximately three million living in Germany, vegan vegetarians, meaning they do without entirely on animal products like meat, fish , eggs, milk and dairy products. At the plate, only to come fruits, vegetables, nuts or leguminous te. The vegan diet is not a uniform diet, but is different to teaching practical tiziert: For example, various Ausprä conditions of the macrobiotic diet or raw food diet. Allen is common that only comes on the vegetable plate. From Vegan - advocates hailed it as the "welfare" diet for humans. And who are ideal feeding, which also have the chance of a good, long pause de health. All concerns about deficiencies, especially the Sor GE to the vitamin - B12 (cobalamin), is before the shortage here and there GE warns, in the various Ve gan - appeased books.
vitamin - B12 is only forms of bacteria GE , there is a water-soluble vitamin can be, absorbed in the stomach hard and men must come together in the intestinal absorption of calcium to be utilized by the body properly. It is important in the human body for blood formation. Find out from it plays a role in the metabolism of carbohydrates, proteins and fats. Moreover, it is necessary for the health sunderhaltung the nervous system and psyche.
As a vegan meet its needs for this important vitamin should Vegan advocates explained as follows: First of all fermented vegetable food, such as cabbage, shoyu, miso bread or drink, are good sources of cobalamin. Also, algae, yeast, parsley, sprouts, and even dried figs provide this vitamin. In addition, bacteria in the intestine produce the B-vitamin. A lack of it is practically impossible, the vegans. The proof that vegan diet really work are, people in India, vegan living since time immemorial.
evil awakening
The Vegan - arguments are quite comprehensible to - but the dream of eternal Independent Health often ends in a bad awakening, as history shows us the little Jana: Jana developed remarkably slow. And since practically doctors in their duty training nutrition issues do not treat table, waving a pediatrician from confident, as the mother of the unsettled question is whether all this may get through the vegan diet. At the age of just over a year, closing Jana Lich very ill, denied the mother's milk and other food. Two days later comes the now almost completely emaciated baby in a coma. In the intensive station is Jana as apathetic. Her whole body trembled incessantly. Her tongue hangs out. The doctors are clueless. The El Tern fear for their lives.
By chance, discovers Jana's mother in an can cause defect that the -like symptoms may - NEM scientific book an indication of vitamin - B12 . Only after repeated pleas by the mother gives to the superintendent: "Sha the vitamin can - B12 ultimately not."
This vitamin - syringe is like a miracle of: The tremor subsides. A few days later is at Jana, begins to crawl, then goes a few steps and speaks so even rudimentary words. The cause of her mysterious disease has been found: A Man gel on the B - vitamin by the vegan diet of the parents. The mother also suffered from some time in a cobalamin deficiency, it was a deficiency in the infant inevitable.
A vitamin B12 deficiency by vegan diet - that the vegan arguments well but not the reality?
common mistake
Vegan advocates like to do for such phenomena as in the case of Jana responsible the so-called intrinsic factor, a stomach-produced protein for the successful absorption of vitamin B12 in the intestine is responsible. In fact, there are patients who have a deficiency of this protein and therefore can not absorb vitamin B12 in sufficient quantities. The cause For example, for the chronic atrophic Scheme gastritis (Magenschleimhautentzün education) be. But in the case of Jana and many other vegan things are completely different: Their diet contains virtually no vitamin - B12. Vegan central - argument elements keep the scientific Uber not test unfortunately stood. -
"There are always allegations that certain plant foods such as pig erkraut or algae as vitamin - B12 -. source should be suitable for vegans This is a very common mistake, "says the university lecturer Dr. Andreas Hahn, He nährungswissenschaftler and Vegan - Ex perte at the University of Hannover, of course. "It has namely used drive in their analysis Ver that are not between co balamin and worthless pseudo - Kobalami NEN may differ. Practice has shown that herbal products, if any, vitamin - B12 inadequate only deliver accordingly. Do not reliable B12 are - sources. The American Dietetic Association ciation "indicates that 80 to 94% of the so-called cobalamin in fermenfier Ten Products worthless pseudo - can be Kobalami ne. No wonder then that many studies and reports from around the world demonstrate, that vegans actually a great risk of B12 - go defect. The B12 - supply from enteric bacteria criteria turns out to be a myth: "It who the although significant amounts of Kobala min produced in the gut, "adds Hahn," but they can not by the body removed be "For the B12 -. synthesis takes place in the intestine section beyond the Absorptionsab . This leaves B12 therefore un the body recovered in the feces. Not
different it is on vegan living, non-ruminant (monogastritischen) animals such as gorillas. Their secret: They eat every now and then their feces and VER worry in this way with the le bensnotwendigen vitamin. However, ruminants such as cows and sheep producers in their rumen (ruminant stomach) cobalamin, the well tolerated for the organism is considered as eligible.
And Vegan - secret of the Indian: your crop is not sprayed with pesticides and clean as ours. In the cereal dekörnern tiny live insects that Vi vitamin - B12 supply. Moreover, their drinking contaminated water with cobalamin-producing bacteria.
of vegan living Indians who have moved to Europe ropa, it was announced that after many years of vitamin - B12 have developed deficiency. It took the half as long as the body very careful with the B - vitamin handle and a large memory, the liver has. Vita min - B12 is the only water-soluble vita min, which can be stored in the body. Enough memory in adults for three to ten years, in a few cases even longer. Children as to have a much smaller memory Cher - why the vegan diet for them is particularly dangerous. Also for pregnant and nursing women, since in this phase, an increased B12 - have needs.
complaints by B 12 - lack
complaints by vitamin - B12 lack insidiously make noticeable bar. Usually they are initially only as MO dismissed instantaneous disturbances. Increasing fatigue and Antriebsar mut. It is simply harder to cope with everyday life. Everything takes longer. Many bekom men with heart palpitations physical Bela equipment and tingling in hands and feet. This can increase up to paralysis. The hair loses its shine. Anorexia is a sometimes, just nausea, vomiting and diarrhea. As a B12 - lack an effect on the enzyme has budgetary, metabolic disorders are the result.
makes on a mental level, the co balamin - deficiency as evidenced by irritability and depression. Also on memory impairment to dementia and dementia are reported.
After about 80 to 90% of the body inventories are used up to B12 is the blood picture clearly visible to a megaloplastäre anemia: Bone marrow is un capable of healthy red blood cells per . Duce The cells are reduced in number re and enlarged at the same time strong. The hemoglobin transport can only be carried out as yet incomplete. Sauer material poverty is the result. In advanced NEN stage heart disease often connect effects and nerve damage to.
particularly treacherous, the development of B12 - lack - damage in raw - Ve ganern run. They eat lots of fresh leafy vegetables that is especially rich in folic acid. Folic acid is capable of a lack of vitamin - to mask B12 long time. This means that the emergence a megaloblastic anemia increase will be delayed while but by the B12 - deficiency caused neuro logical changes are progressing. At the time of diagnosis of anemia can be severe irreversible damage to the already present Central nervous system. Therefore, the megaloblastic anemia as the sole diagnosis is not appropriate. to make
To a certain diagnosis, the following parameters are required: The vitamin B12-normal value in serum, the normal value of serum folate, red cell, normal value, the normal hemoglobin value, the MCV (mean cell volume), the MCH value (mean cell hemoglobin), homocysteine, and the Methyimalonsäure.
therapy
The treatment of B12 deficiency symptoms is done by filling the missing vitamin. With a dire shortage are high doses of B12 - spraying, the best solution solution. suffice in many cases as possible as vitamin - B12 - tablets and regular overeating B12 - rich food. Particularly rich is the liver, but kidney and heart. Reliable sources also fish, meat, eggs and dairy products, apart from the butter.
While these measures the serum mirror of the vitamin - normalize B12 and megaloblastic anemia can heal, it will take for the neurological disturbances capacities up to 18 months until healing occurs. In some cases, however, the damage to the nervous system is irreversible.
Vegan - myth
nutritionists now agree: It's a myth that you can cancel without further teres all animal products from the diet permanently. So at least, milk and milk products are consumed. "These products provide sufficient vitamin - B12," says Dr. Hahn. "With Lacto - and Ovo - Lacto - vegetarian ren there is no B12 -. deficiency "
cobalamin way, is heat stable, so that it is not destroyed by cooking. The B12 - needs could be covered for example with at least 380 grams of milk and dairy products per day and one egg per week. The minimum requirement of an adult Senen is about 2 micrograms of vitamin - B12 per day.
Dairy products also supply other Ren substances to which vegans are sometimes underserved: to "energy, protein, calcium , vitamin - D and zinc may problematic be automatically, "said Hahn. His studies on vegans recently to the day brought light that one in three vegans also inadequate vitamin - B6 is supplied. In contrast, clinically documented mented iron deficiency in vegans not more frequently than in the general population.
What should vegans
who is dependent due to allergies or other circumstances, despite everything, on a vegan diet, "should ungedingt ensure appropriate dietary supplement 'warning tap. This is primarily for the vitamin - B12. In England for example as it is common for vegans with Vita min - B12 fortified Soiaprodukte Ver . Zehren Commercial Soiamiich other hand, as a full-milk substitutes, not only to B12, totally inappropriate. There are also vitamin - juices or B12 - supplementation te. be warned in this context that all However Ver of false advertising promises various supplements that are offered mainly in health food stores. Although they are often the ideal B12 - praised source, neither algae tablets, such as spirulina, even yeast appropriate B12 - delivery suppliers. On the contrary: You mentioned before al lem ineffective pseudo - Kobal amines which are capable of blocking the absorption of the active B12.
Effective Vitamin - B12 - tablets must contain active cobalamin (cyanocobalamin or Hydoxocobalamin). A daily che addition of 5 micrograms Vitaimin - B12 should be sufficient to assess the Ernährungsexper th. In addition, they advise Vega partners on a regular basis their serum - let B12 investigate levels in order to take any risk.
Long term Taking higher doses catalyzed vitamin supplements should be respects be that relatively little is known about the interactions of these substances in the body. Most of them are dependent speed to another. Although it is often claimed, that excess B12 easily divorced from is, there is evidence that a B12 - concerned to make top shot an iron deficiency can bush. This experience made some vegan after after long stringent B12 - developed supplementation Eisenman gelsymptome.
is therefore in the long run the natural way is the safest: a complete and balanced generic diet that provides all the materials in sufficient quantities and in the right proportion.
