Food Insecurity Later in Life Linked to Nearly 4 Times Higher Dementia Risk

A new study from the University of Michigan reveals that older adults dealing with food insecurity in later life face nearly four times the risk of developing dementia compared to those who remain food secure. The research, published in The American Journal of Clinical Nutrition, emphasizes the hidden dangers of food insecurity in aging populations.

Dr. Daniel Preston, founder of LiveInCare USA, highlights the importance of the findings, noting that the association between food insecurity and dementia was most pronounced in later life. After adjusting for various socioeconomic and health factors, the study found that older adults who experienced food insecurity in both midlife and later life had a 40 percent probability of dementia, compared to an 11 percent probability among those who remained food secure throughout their lives.

Those who faced food insecurity only in later life showed a 34 percent increased probability of dementia. While the researchers cannot definitively establish a direct causal link between food insecurity and dementia, they suggest that the timing of this hardship plays a significant role in long-term cognitive health. Study author Noura Insolera calls for revisiting the generosity of federal food assistance programs, such as SNAP, which proved effective during the pandemic.

Preston stresses that food insecurity is addressable through meal delivery services, food assistance programs, and increased attention to nutrition for older individuals.
