Final answer:
The statement is false; fat-soluble vitamins can be stored in the body's fatty tissues, while water-soluble vitamins are not stored and are excreted if in excess.
Step-by-step explanation:
The statement suggested in the question is false. Fat-soluble vitamins, which include vitamins A, D, E, and K, can be stored in the body's fatty tissues and are not used up as quickly. In contrast, water-soluble vitamins, such as the B vitamins and vitamin C, cannot be stored in the body and any excess is excreted in the urine.
While some vitamins can be synthesized by the body, like vitamin D from sunlight exposure, most are obtained through diet. For example, the body can convert ß-carotene from foods like carrots and sweet potatoes into vitamin A. Excess fat-soluble vitamins can lead to hypervitaminosis, which is a condition caused by the accumulation of vitamins in the lipid stores of the body. On the other hand, the risk of hypervitaminosis with water-soluble vitamins is rare unless there is an intake of excessive supplements.
