Study Notes
Impact of Diet and Exercise on Brain Health
- Pathogenesis of many neurological disorders involves an energy component
- Top 10 leading causes of death in the US in 2010 include heart disease, cancer, and Alzheimer’s disease
- Metabolic disorders such as diabetes reduce brain capacity and increase the risk of neurological disorders
- Chronic obesity is associated with structural brain changes and increased risk for neurological and psychiatric disorders
- Rise in consumption of sugars is associated with increased incidence of obesity
- Saturated fats and sugars, when consumed in excess, are associated with obesity, metabolic syndrome, and increased risk for Alzheimer’s disease and depression
- Omega-3 fatty acids, particularly DHA, are crucial for brain structure and function, impacting learning, memory, emotions, and protecting against neurodegeneration
- Exercise helps counteract the effects of unhealthy diets by restoring brain-derived neurotrophic factor (BDNF) and cognitive loss
- Exercise improves brain function, decreases anxiety, improves focus and concentration, promotes growth of new brain cells, and protects the brain from aging and neurodegenerative diseases
- Exercise reduces cognitive impairment in aging, increases brain volume, and improves cognitive performance
- Diet and exercise have collaborative effects on the central nervous system and periphery, promoting membrane homeostasis, neuronal signaling, and synaptic plasticity
- Epigenetic mechanisms mediate the complex interactions between genetic factors and the environment, influencing brain health and cognitive reserve
