Have any studies shown that certain foods might contribute to irregular heart rhythms? My doctor told me to avoid all sources of caffeine, and that helped to reduce my “missed” beats. Over the years, I have noticed that several foods seem to cause an increase in my irregular heartbeats. Fresh apples, of all things, appear to be one—along with others.
Yes, many foods like caffeine and alcohol can cause irregular heartbeats. Sometimes swallowing, coughing, or an upset stomach can also set off palpitations. Some energy drinks have ingredients that can affect the heart. It seems you are sensitive to a variety of stimuli, so the best thing to do is avoid them.
