Final answer:
The most appropriate nutritional information for a parent group is to limit fats to 30% or less of total calories, choose foods with unsaturated fats, and not use whole milk after the child is 2 years old.
Step-by-step explanation:
The most appropriate nutritional information for a parent group provided by a nurse would be to limit fats to 30% or less of total calories (65-85 g) and to choose foods with unsaturated fats. This would contradict option 3, which states that saturated fats are the healthiest fat choice. Additionally, option 2, which suggests limiting carbohydrates to 10-15, is not sufficient because carbohydrates should make up 50-70% of total calories, according to the recommended ratio. Lastly, option 4, which advises using whole milk until the child is 2 years old, is not the best choice because after the age of 2, children are generally recommended to switch to low-fat or fat-free milk.
