Which is a property of thiamin nutrition?

Significant amounts are found in leafy vegetables Deficiency results in cheilosis and marked dermatitis Poor sources include seafood and cheeses Participates in activation of prothrombin

Correct Answer:

Poor sources include seafood and cheeses

Explanation:

Thiamin is a water‑soluble vitamin whose nutrition is defined by its dietary sources and deficiency signs. The richest sources are pork, whole grains, legumes, and fortified cereals; dairy products and seafood do not provide large amounts, so they are considered poor sources. Leafy greens contribute only small amounts compared with the best sources. The skin/mucous membrane changes described as cheilosis and dermatitis are linked to riboflavin (B2) deficiency, not thiamin. A lack of thiamin leads to beriberi and related neurologic issues, not the mucocutaneous symptoms mentioned. Activation of prothrombin involves vitamin K, not thiamin. So, the statement that seafood and cheeses are poor sources correctly reflects thiamin nutrition.
