As indicated by the RENI, all persons throughout life need ____.

The correct response emphasizes that all individuals require the same essential nutrients throughout their lives, but the amounts needed vary depending on several factors, such as age, gender, health status, and activity level. This principle aligns with the Recommended Nutrient Intakes (RENI), which recognize that while the basic types of nutrients remain consistent, the specific needs of individuals can differ significantly. For example, children and pregnant women may need higher amounts of certain nutrients like calcium and iron compared to older adults.

Understanding that nutrient needs change throughout different life stages is crucial for public health nursing, as it informs nutritional guidelines and recommendations tailored to specific populations. This knowledge enables healthcare professionals to develop effective intervention strategies to address unique nutritional needs and promote overall health and well-being at various stages of life.
