Resumen:
Introduction: Patients with tension-type headache (TTH) are characterized by recurrent
pain that can become disabling. Identifying the dietary triggers of headaches has led to defining
dietary strategies to prevent this disease. In fact, excessive dietary intake of Omega-6 (ω-6) fatty
acids, or an ω-6: ω3 ≥ 5 ratio, typical of Western diets, has been associated with a higher prevalence
of headaches. The objectives of the present study were to compare dietary fatty acid intake between
participants with and without chronic TTH and to investigate the association between dietary
fatty acid intake, pain characteristics, and quality of life in patients with chronic TTH. Methods:
An observational study was conducted, comparing healthy participants (n = 24) and participants
diagnosed with chronic TTH for more than six months (n = 24). The variables analyzed were dietary
fatty acid intake variables, the Headache Impact Test (HIT-6), and the characteristics of the headache
episodes (intensity, frequency, and duration). Results: The TTH group reported a significantly higher
intake of saturated fatty acids (SFAs) but similar intakes of monounsaturated fatty acids (MUFAs),
polyunsaturated fatty ac...
