Final answer:
The statement about zinc deficiency disturbing the absorption of other nutrients is true. Zinc plays a critical role in various physiological processes. Essential nutrients cannot be synthesized in sufficient amounts by the body and must come from the diet.
Step-by-step explanation:
The statement that zinc deficiency also disturbs the absorption of other essential nutrients is true. Zinc is an essential trace mineral that plays a role in numerous biochemical pathways and physiological processes, including the function of enzymes, immune response, and protein synthesis. A deficiency in zinc can disrupt these processes and also affect the absorption of other nutrients such as iron and copper. Furthermore, inadequate zinc levels may lead to altered taste, impaired growth, and delayed wound healing.
Regarding essential nutrients, by definition, they are substances that must be obtained from the diet because they cannot be synthesized by the body in sufficient amounts to meet its needs. Hence, statement 11.a that essential nutrients can be synthesized by the body is not true. Essential nutrients are crucial for various body functions and must be part of a healthy diet.
For your reference regarding specific essential nutrients, vitamin D is vital for the absorption of calcium, and a deficiency in it can cause rickets, leading to improper bone development in children. Dietary lipids facilitate the absorption of some minerals, including folic acid, iron, and magnesium.
