tiamiinista

Tiamiini, also known as vitamin B1, is an essential nutrient that plays a vital role in carbohydrate metabolism. It is a water-soluble vitamin, meaning the body does not store it in large amounts and requires a regular intake from the diet. Tiamiini is crucial for converting carbohydrates into energy that the body can use. It is also involved in the proper functioning of the nervous system, muscles, and heart.

Deficiency in tiiamiini can lead to a condition called beriberi, which can manifest in various forms. Dry beriberi primarily affects the nervous system, causing symptoms such as difficulty walking, numbness in the extremities, and paralysis. Wet beriberi impacts the cardiovascular system, leading to edema (swelling), rapid heart rate, and heart failure. A severe form of tiiamiini deficiency, particularly in individuals with chronic alcoholism, is known as Wernicke-Korsakoff syndrome, characterized by confusion, memory loss, and eye movement abnormalities.

Good sources of tiiamiini include whole grains, pork, legumes, nuts, and fortified cereals. The recommended daily intake varies based on age, sex, and physiological status. Tiamiini is relatively stable when heated in dry conditions but can be destroyed by prolonged exposure to heat in alkaline or neutral solutions. Supplementation is sometimes recommended for individuals at risk of deficiency, such as those with alcoholism, malabsorption issues, or undergoing dialysis.
