Thiamin deficiency can result from a diet heavy in white flour, white sugar, and other highly processed carbohydrates. People initially have hazy symptoms like weariness and irritation, but a severe deficit (beriberi) can have an impact on the brain, heart, muscles, and nerves. Based on the symptoms and a positive reaction to thiamin supplements, the diagnosis is made. Supplements high in thiamin, typically taken orally, can make up for the deficit. The dietary intake of thiamin, also known as vitamin B1, is very high. It is necessary for the breakdown of carbs, proteins, and lipids as well as for healthy neuron and heart function. Consuming too much thiamin is not harmful because it is non-toxic. Dried yeast, whole grains, meat, fortified cereals, nuts, legumes, and dried fruit are excellent sources of thiamin. People who eat mostly highly processed carbohydrates (such polished white rice, white flour, and white sugar) and young adults with severe anorexia may not get enough thiamin. Almost all of the vitamins are removed during rice polishing. People who drink too much frequently replace food with alcohol and don’t get enough thiamin are at a greater risk of having this condition. Additionally, alcohol may make the body require more thiamin by preventing the absorption and metabolism of this vitamin. disorders or ailments that make the body more dependent on thiamin, such as hyperthyroidism, pregnancy, nursing, rigorous exercise, and fever. conditions that impede the absorption of thiamin, such as protracted diarrhoea.
