Which of the following statements is true about fat-soluble vitamins?

1. They are excreted easily through urine

2. They can be stored in the body's fat tissues

3. They must be consumed daily

4. They are soluble in water

The correct answer is: They can be stored in the body's fat tissues

Fat-soluble vitamins, which include vitamins A, D, E, and K, are unique in that they can be stored in the body's fat tissues and the liver. This characteristic means that, unlike water-soluble vitamins that must be consumed more frequently due to their quick excretion in urine, fat-soluble vitamins can be retained in the body for extended periods. They are absorbed along with dietary fat and utilized by the body over time. This storage capability allows the body to maintain a reserve of these vital nutrients, which can be particularly beneficial for maintaining health when dietary intake might fluctuate. Consequently, option B accurately describes the nature of fat-soluble vitamins and their storage system in the body.
