Final answer:
The incorrect combination of mineral to sources given is d. Iron—coffee, tea, and cocoa are not considered good sources of iron due to compounds that inhibit its absorption.
Step-by-step explanation:
With respect to educating patients on the functions of minerals in the body, the combination of mineral to sources that is incorrect is d. Iron—nuts, whole grains, vegetables are indeed good sources of iron, but coffee, tea, and cocoa contain compounds that can inhibit the absorption of iron, and are not considered good sources. Egg yolks do have iron, but coffee, tea, and cocoa are not typically promoted for their iron content.
Minerals are essential for body processes such as bone and tooth formation, muscle function, and nerve signaling. Good sources of major minerals include leafy, green vegetables, whole grains, milk, and meats, which contribute to the body's nutritional balance.
Calcium is vital for strong bones and teeth, and it can be found in foods like milk and green leafy vegetables. Potassium is important for normal nerve and muscle function and can be found in bananas and potatoes, among others. Conversely, while sodium is an essential nutrient, excessive intake can lead to health issues, and iron is critical to the formation of hemoglobin, and can be found in nuts and vegetables. A balanced diet must be achieved to properly obtain the quantities needed for these essential minerals without overconsuming any particular one.
