Which statement best defines food insecurity in older adults and identifies common contributing factors unique to this population?

Food insecurity is unreliable access to sufficient nutritious food; in older adults unique contributors include inability to prepare food, limited mobility to obtain groceries, and difficulty physically consuming food due to dental or swallowing problems.

Food insecurity in older adults is defined as selective food avoidance for cultural reasons and is primarily due to overabundance of food preparation skills among elders.

Food insecurity exclusively means lack of cooking knowledge, so educational programs alone always eliminate insecurity in the elderly.

Food insecurity only refers to the caloric insufficiency regardless of food quality; older adults are unaffected because social programs automatically guarantee unlimited access to foods.
