“What foods to avoid with heart palpitations?”

Caffeine is the primary ingredient. Not only coffee, tea and chocolate but contained in many weight loss products. Monitor weight loss products for stimulants such as Guarana and phenylephrine. One might benefit from doing a food elimination diet. I found that certain foods in the cabbage family markedly increased palpitations. Regular head cabbage and Brussels sprouts are not an issue but others in the cabbage family such as kale and bok choy are problematic. Hope this is helpful.
