Elderly institutionalized adults who consume no milk and receive little or no sun exposure are at the highest risk of developing a vitamin D deficiency. This is because vitamin D is primarily obtained through sun exposure and fortified foods like milk. As people age, their skin becomes less efficient at producing vitamin D from sunlight, and institutionalized adults may have limited access to sunlight and fortified foods. The other options also have a risk of vitamin D deficiency but not as high as elderly institutionalized adults.
