Summary
The purpose of this study is to learn if increased dairy food consumption helps brain health in older adults by protecting nerve cells from damage.
Detailed description
Eating more dairy foods may improve brain health as people age by increasing the brain's natural defenses to protect nerve cells against chemical stress. Researchers think there may be a relationship between the brain's natural defense system and the amount of dairy food intake. Strengthening these defenses could provide beneficial protection to the brain against neurodegenerative age-related diseases and cognitive decline. Glutathione (GSH) is a metabolite in the human brain protective system. It plays a key role in protecting cells against oxidative stress, which is one of the major processes contributing to aging and neurodegeneration. Preliminary findings suggest that there may be a correlation between dairy food intake and GSH levels in the aging brain. Magnetic Resonance Spectroscopy (MRS) measures chemicals in the brain. It is a noninvasive measure of the effects of dairy food intake on the major protective metabolite levels in the living human brain in aging. This study involves using an MRI with special MRS scans to see if adequate dairy food intake may aid in enhancing cerebral protective capacity to fight against age-related disease and cognitive decline in the brain. Participants will be asked to make a total of six visits to the research site. Participation will last about 3 months.
