Which of the following is a common dietary deficiency in older adults?

Calcium is a common dietary deficiency in older adults primarily because of changes in dietary habits, decreased absorption, and a higher need for bone health as individuals age. Calcium plays a crucial role in maintaining bone density and preventing conditions like osteoporosis, which is especially important for older adults who are at increased risk for fractures and bone-related issues. Additionally, factors such as reduced dairy consumption and difficulty in absorbing nutrients can contribute to lower calcium intake in this age group.
