Fried food intake and risk of nonfatal acute myocardial infarction in the Costa Rica Heart Study
Economic development in middle income countries has led to a noticeable rise in the availability of commercial deep fried foods and lifestyles that require eating meals "on the go" and outside of the home. Yet, data from these countries where fried foods were traditionally prepared at home are scarce, despite several studies showing the potential adverse effects of fried food consumption on risk for heart disease. We aimed to examine whether consumption of fried foods inside or outside of the home is associated with an increased risk of myocardial infarction (MI) among Hispanic/Latinos living in Costa Rica. Participants were incident cases of a first acute MI (n 2,154) and randomly selected controls matched for age, sex, and residence (n 2,154) After adjustment for traditional cardiovascular risk factors, including history of diabetes, history of hypertension, smoking, abdominal obesity, income, educational years, occupation, alcohol intake, dietary intakes of saturated fatty acid, fiber intake, and total energy intake, the multivariable adjusted odds ratio (OR, 95% CI) for risk of MI were 1.00 (reference) 1.02 (0.86 1.21) 1.26 (0.81 1.95) and 1.58 (1.08 2.30) for intake of fried foods outside of the home <1/week, 1 3/week, 4 6/week, and 1/day, respectively (P trend 0.02) and 1.00, 0.81 (0.65 1.00) 0.81 (0.61 1.09) and 0.93 (0.72 1.19) respectively (P for trend 0.65) for intake of fried foods inside the home. The data suggest that consumption of fried foods outside of the home, a practice that has been associated with economic development, could have adverse effects on cardiovascular disease.
