Foods rich in flavonoids offer a number of neuroprotective properties and can
decrease rates of cognitive decline and potentially slow the progression of many neurodegenerative diseases, such as Alzheimer's disease.
There were also several studies that reported changes in physiological and
cognitive outcomes including increased heart
rate variability,
decreased cortisol concentration, improved respiratory muscle and abdominal strength, greater flexibility, improved planning and execution
of cognitive tasks, and even
declines in physiological stress reactivity.
