Each meal must meet _____ of the DRI for older adults and must follow the most recent __________.

The correct answer highlights the importance of meal planning for older adults by stating that each meal must meet one-third of the Dietary Reference Intakes (DRI) for this population. This benchmark ensures that older individuals receive adequate nutrition within their daily caloric intake, promoting overall health and wellness.

Meeting one-third of the DRI at each meal supports the nutritional requirements that are crucial for maintaining health, preventing chronic diseases, and managing age-related conditions. Additionally, referencing the most recent Dietary Guidelines for Americans reinforces the commitment to evidence-based recommendations that provide guidance on healthy eating and physical activity. These guidelines are updated periodically to reflect current scientific knowledge and public health recommendations, ensuring that meal plans are aligned with the latest understanding of nutrition.

On the other hand, the other choices suggest different portions of DRI or refer to MyPlate recommendations incorrectly, which may not align with established nutritional standards for older adults. While MyPlate provides a useful framework for balanced meals, the specific focus on one-third of the DRI emphasizes a more tailored approach for the needs of the aging population.
