Effects of hyperprotein diet on anxiety, haemodynamics and morphofunctional aspects of the heart of Wistar rats.

New Findings: What is the central question of this study? The consumption of a high-protein diet has been associated with an anxiogenic factor that can influence anxiety and possible cardiovascular changes: does the consumption of a high-protein diet interfere with anxiety, haemodynamics and morphofunctional aspects of the heart of Wistar rats? What is the main finding and its importance? Our study showed that the high-protein diet did not interfere with anxiety and haemodynamics. The animals in the hyperproteic group showed positive heart adaptations characterized by less work and lower heart rate without impairing ejection fraction and systemic blood pressure.

Abstract: Anxiety is a mechanism preparatory to a response in situations of threat and danger, involving behavioural, affective and physiological factors.
