Why sour make your heart palpitation?

Sour foods can trigger heart palpitations in some individuals due to their effect on the nervous system and digestive processes. The acidity in sour foods may stimulate the vagus nerve, which can influence heart rate. Additionally, the consumption of sour foods can lead to increased gastric acid production, potentially causing discomfort or acid reflux that might contribute to palpitations. If palpitations persist, it’s advisable to consult a healthcare professional.
