Abstract:
The autonomic nervous system (ANS) plays a key role in maintaining physiological homeostasis by regulating cardiovascular activity, gastrointestinal motility, and stress responses. The aim of this review was to analyze how selected dietary components, and complete nutritional models affect ANS activity, with particular emphasis on underlying physiological mechanisms and practical dietary recommendations in cases of sympathetic or parasympathetic hyperactivity. This paper discusses how caffeine, simple sugars, and highly processed foods tend to enhance sympathetic output, whereas omega-3 fatty acids, magnesium, dietary fiber, promote autonomic balance by reducing sympathetic tone and enhancing parasympathetic function. Based on a review of recent scientific studies, it can be concluded that nutrition and lifestyle interventions can significantly modulate ANS function and serve as valuable tools in the management of chronic stress, anxiety, hypertension, and functional gastrointestinal disorders.

Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...
