Final answer:
Option A) 1 roll, 60g is the closest to a standard single serving size of whole wheat bread according to the sample nutrition label, meeting the recommendations of the Healthy Eating Guidelines and contributing appropriately to the six to eleven daily servings of grains needed for a balanced diet.
Step-by-step explanation:
When considering the amount of a whole-wheat roll to consume in line with current health recommendations, it is important to look at the provided information regarding the role of grain products in a healthy diet. The Healthy Eating Guidelines recommend filling a quarter of your plate with grains, such as cereals, bread, crackers, rice, and pasta, and ensuring that at least half of your daily grain intake should be whole grains. A single slice of whole grain bread typically contains about 15 grams of carbohydrates.
Applying these guidelines to the options provided, we would consider the sample nutrition label, which states that a serving of a similar food is 55g. This would suggest that option A) 1 roll, 60g is the closest to a standard single serving size. This portion size would adequately contribute to the servings recommended from the bread/cereal/rice/pasta group, considered to be between six to eleven servings each day for maintaining a balanced diet, according to the food pyramid or diet recommendations.
