Final answer:
Iron is the essential nutrient that should be considered for the dietary intake of a 35-year-old female patient based on her weight, height, and activity level, particularly because females require extra iron due to menstruation.
Step-by-step explanation:
For a 35-year-old female patient weighing 230 lbs, with a height of 5 feet 4 inches, and a light Mifflin activity factor (1.53), iron is an essential nutrient to consider for her dietary intake. According to the provided information, females require extra iron due to menstruation. This is emphasized by the micronutrient needs which state that young women, because of the iron lost during menstruation, have to ensure they have sufficient iron in their diet. Additionally, the dietary information provided suggests a daily iron intake of 40 mg for a balanced diet, further reinforcing the importance of this nutrient for the patient's diet.
