Deficiency linked to beri-beri (heart failure)?

Explanation:
Thiamin (vitamin B1) deficiency is linked to beri-beri, especially the wet form that causes heart failure. Thiamin acts as a coenzyme in energy metabolism, enabling the heart to produce ATP efficiently. Without it, energy production drops in the heart, leading to fluid buildup and heart failure symptoms. Historically, beri-beri occurred where diets relied on polished white rice, which is low in thiamin. Other vitamins cause different deficiency diseases—riboflavin deficiency affects the skin and mucous membranes, niacin deficiency leads to pellagra, and vitamin C deficiency causes scurvy—so they are not associated with the heart-related form of beriberi.
