Which of the following nutrients is particularly emphasized for older adults?

Vitamin B12 is particularly emphasized for older adults due to several key factors that impact nutrient absorption and utilization in this age group. As people age, the production of stomach acid often decreases, which can impair the ability to absorb Vitamin B12 from food sources. This vitamin is crucial for maintaining healthy nerve function, producing DNA, and aiding in the formation of red blood cells. Deficiencies in Vitamin B12 can lead to serious health issues such as anemia and neurological problems, which are more common in older populations.

Additionally, many older adults may follow a diet that includes fewer animal products, which are the primary sources of Vitamin B12, increasing the risk of deficiency. Therefore, monitoring and ensuring adequate intake of Vitamin B12 through diet, supplementation, or fortified foods becomes vital for their overall health and wellbeing.

While protein, zinc, and fiber are also important nutrients for older adults, Vitamin B12's specific role in preventing deficiency-related complications highlights its unique emphasis in this demographic group's nutritional needs.
