Fat-soluble vitamins, such as vitamins A, D, E, and K, differ from water-soluble vitamins in terms of their absorption and excretion in the body. Here's a breakdown to help you understand the statement in the question:
1. Fat-soluble vitamins are absorbed along with dietary fats and are stored in the body's fatty tissues and liver. Unlike water-soluble vitamins, which are not stored in large amounts and are excreted in the urine, fat-soluble vitamins can be stored in the body for longer periods.
2. Because of their ability to be stored, fat-soluble vitamins are not needed in the diet daily. Instead, they can be accumulated over time, and excessive intake can lead to toxicity as the body struggles to eliminate the excess amounts efficiently.
3. Water-soluble vitamins, on the other hand, are not stored in the body to the same extent as fat-soluble vitamins. They dissolve in water and are excreted through the urine more readily. This is why water-soluble vitamins like vitamin C and the B-complex vitamins need to be consumed regularly in the diet as they are not stored in the body in large amounts.
Based on the information provided, the statement in the question that fat-soluble vitamins are more readily excreted from the body than water-soluble vitamins and are therefore needed in the diet daily is **False**. Fat-soluble vitamins are not excreted as readily as water-soluble vitamins due to their storage capacity in the body, and they do not need to be consumed daily in the same way water-soluble vitamins do.
