Question

BlackTom AI · Accepted Answer

Thiamin (vitamin B1) is a water-soluble vitamin that functions as a coenzyme (thiamin pyrophosphate) in carbohydrate metabolism and energy production; typical rich sources include whole grains, meats (especially pork), and many types of fish, while dairy products generally provide only small amounts.

1. Relevant knowledge points and concepts
- Thiamin is water-soluble and concentrated in tissues involved in energy metabolism.  
- Good dietary sources: whole grains (and enriched grain products), pork and other meats, legumes, nuts, and many fish.  
- Dairy products (cheese, milk) are relatively poor sources of thiamin compared with the above groups.  
- Deficiency produces beriberi and Wernicke-Korsakoff syndrome due to impaired carbohydrate metabolism.

2. Step-by-step reasoning process
- Examine each option and compare typical thiamin content per serving.  
- Whole grains: naturally contain thiamin in the germ and bran; enriched grains are fortified with thiamin → therefore high.  
- Meat: especially pork, contains substantial thiamin; other meats also supply moderate amounts → therefore a good source.  
- Fish: many fish species provide appreciable thiamin (e.g., tuna, trout) → therefore a good source.  
- Cheddar cheese: as a dairy product, contains only trace thiamin relative to the other options → therefore not a high source.

3. Intermediate steps / evidence
- Typical food composition tables show whole grains and enriched cereals often provide 0.5–1.5 mg/serving; pork and some fish ~0.5–0.9 mg/serving. Cheddar cheese generally provides <0.1 mg/serving, a low amount.

4. Why the correct answer is correct
- Cheddar cheese does not supply thiamin in high quantities; dairy lacks the germ and bran components of grains and does not concentrate thiamin like muscle tissues (meat/fish) do. Thus it is the exception among the listed items.

5. Why the other options are incorrect
- Fish: contains measurable thiamin and is considered a source.  
- Whole grains: naturally and/or by enrichment are high in thiamin.  
- Meat: especially pork, is well-known to be rich in thiamin.

6. Conclusion
Cheddar cheese is the exception and correctly identified as the food not high in thiamin. This matches the provided answer: cheddar cheese.
