In the context of human nutrition, which phrase does NOT describe a mineral?

• A. A nutrient that can be destroyed by heat, light, or oxidation

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the definition of minerals in human nutrition. Minerals are inorganic elements that the body requires in small amounts for various physiological functions.
2. Step 2: Recognize that minerals are inorganic, meaning they do not contain carbon and are not derived from living organisms, unlike vitamins which are organic.
3. Step 3: Note that minerals are stable substances that retain their chemical identity during digestion and absorption; they are not destroyed by heat, light, or oxidation.
4. Step 4: Identify that minerals are essential components of structures like bones and teeth, for example, calcium and phosphorus.
5. Step 5: Conclude that the phrase 'A nutrient that can be destroyed by heat, light, or oxidation' does NOT describe a mineral, because minerals are stable and cannot be destroyed by these factors.
