VITAMIN B1 (THAIMIN)

Thiamin, or vitamin B1, is a crucial nutrient vital for cell function and energy metabolism. Discovered through historical observations of deficiency symptoms, especially in diets lacking variety, it was notably absent in refined grains like polished rice compared to whole grains. Adults require around 1.1 to 1.2 mg daily, slightly more for pregnant and lactating women at 1.4 mg, with no defined upper limit for intake. Deficiency can lead to serious health issues affecting the heart and brain due to their high energy demands. Good sources include meats, fish, whole grains, legumes, and enriched products like bread and cereals, ensuring a balanced diet to maintain optimal health.
