Omega-3 fatty acids (EPA and DHA) protect neuronal membranes and support brain cell communication, with low intake linked to age-related cognitive decline and Alzheimer's risk. B vitamins, vitamin D, antioxidants, and plant-based foods combat oxidative stress in the brain and may slow certain types of brain atrophy in mild cognitive impairment.

Agriculture (omega-3 sources, leafy greens)
Consumers may increase spending on omega-3 supplements, organic leafy greens, whole grains, and functional foods. Healthcare costs could decrease long-term if cognitive decline prevention reduces dementia-related care expenses. Demand for preventive nutrition products will likely rise.
Potential for health agencies to update dietary guidelines and promote preventive nutrition education. Possible regulatory scrutiny of health claims on supplement packaging. Public health campaigns may emphasize nutrition's role in dementia prevention, affecting food labeling and marketing standards.
