All about vitamins: vitamin B1

Vitamin B1 that is, thiamine plays the most important role in the energy supply system of the nerves, but it is also pivotal in the regulation of carbohydrate metabolism.

Among meat products Vitamin B1 is to be found mostly in liver and pork, but yeast, bran wheat, rough rice (not the white one!), different oil-seeds (especially peanut) and oat flour are also rich in thiamine. Aside from these, vitamin B1 can be found in most of the vegetables, especially leguminous ones.

Vitamin B1 helps the body disintegrate and alter carbohydrate, fat and alcohol, and also takes care of the optimal activity of nerves and heart muscles.

If your body gets too little vitamin B1 that can lead to fatigue, memory and sleep problems and also stress. In case of regular alcohol consumption, fever, heavy physical work or diarrhea, the body's need for this vitamin increases, but inaccurate lifestyle choices can also contribute to vitamin B1 deficiency. In Hungary more than 10 percent of overall habitants suffer from vitamin B1 deficiency, especially older people. In case one's body gets an acutely small amount of thiamine, red grape acid cumulates in the blood and in the central nerve system, which in turn can lead to dysfunctions of the nerve system and heart failure. Severe vitamin B1 deficiency, which is called beriberi, is very rare in civilized societies.

The fastest way of prevention is the change of your lifestyle. It is not only because of thiamine demand that it is worth avoiding food made of low grain wheat, white bread or shiny rice, for vitamin B1 can be found most importantly in the skin of grains.

Vitamin B1 cannot cause problems for your body, it cannot be "overdosed". It does not have any toxic effects even in the case of consuming well over the recommended daily intake.
