Question

Which of the following is the BEST source of thiamin?

A) a fruit salad
B) a baked sweet potato
C) a glass of milk
D) a bowl of whole-grain cereal

Answer 1

A bowl of whole-grain cereal is the best source of thiamin compared to the other options, as whole grains are a rich source of this vitamin.

Step-by-step explanation:

The best source of thiamin among the options given is D) a bowl of whole-grain cereal. Thiamin, also known as vitamin B1, is abundant in whole grains, which makes whole-grain cereals a great choice. The daily requirement for thiamin is important to consider as it is a water-soluble vitamin and cannot be stored in the body for long periods, with the exception of a short duration in skeletal muscle. In contrast, options such as a fruit salad, a baked sweet potato, and a glass of milk contain less thiamin compared to whole-grain cereals.

Answering a related question, among thiamine, phosphorous, folic acid, and vitamin C, it is phosphorous that is stored in the body (Option B).

Furthermore, when discussing water-soluble vitamins as per another question, vitamin C (Option D) is the correct answer.

Answer 2

A bowl of whole-grain cereal is the best source of thiamin out of the given options, due to the high thiamin content in whole grains. Thiamine is a water-soluble vitamin that must be regularly included in the diet as the body cannot store it for extended periods.

Step-by-step explanation:

The best source of thiamin among the options provided is D) a bowl of whole-grain cereal. Thiamine, also known as vitamin B1, is critical for energy metabolism in the body and has its richest sources in whole grains, along with other foods like nuts, seeds, pulses, and animal products. Since a bowl of whole-grain cereal predominantly consists of whole grains, it is likely to offer a higher content of thiamin compared to the other options listed, such as a fruit salad, a baked sweet potato, or a glass of milk.

It is important to note that thiamine cannot be stored in the body for long periods and is excreted in the urine, necessitating a regular dietary intake. Some food sources rich in thiamin include rice bran, wheat bran, nuts, seeds, beans, lentils, fish, meat, and milk. In contrast, vegetables like potatoes contain less of this vitamin.
