Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Unsaturated fats, particularly polyunsaturated (PUFAs) and monounsaturated fats (MUFAs), are supported by some scientific evidence for cardiovascular benefits, including potential effects on heart rhythm disorders such as atrial fibrillation (AFib) and palpitations. Epidemiological and clinical studies suggest that diets rich in unsaturated fats—like those found in olive oil, nuts, and fatty fish—are associated with reduced risk of cardiovascular diseases. Some observational studies and randomized controlled trials have suggested that omega-3 fatty acids (a type of PUFA) may reduce the incidence of atrial fibrillation, especially among individuals with existing heart disease, though results are inconsistent and effect sizes are modest. The theoretical basis is that unsaturated fats can modulate cardiac cell membrane function, reduce inflammation, and improve lipid profiles, all of which may influence arrhythmia risk. However, large-scale meta-analyses and systematic reviews have shown mixed results, with some showing benefit and others showing little or no effect on AFib or palpitations. Major guidelines do not specifically recommend unsaturated fats as a treatment for arrhythmias, though they do endorse them for general heart health. In summary, while there is some scientific rationale and preliminary evidence suggesting a role for unsaturated fats in supporting heart rhythm, current evidence is not strong or conclusive for their use specifically to treat or prevent fibrillation or palpitations.
