The Relationship between Carbohydrate, Fiber, and Sugar Intake with Premature Heart Disease

Cardiovascular disease (CVD) is an important public health issue in the world as its morbidity and mortality rate is increasing which depends on several factors. The purpose of this study is to investigate the relationship between carbohydrate intake and premature heart diseases.

This case-control study was conducted on 972 people (450 women and 522 men) who referred to Chamran and Asgariye hospitals in Isfahan, Iran, for angiography. Based on the results of angiography, patients were divided into two groups: case and control. In order to evaluate dietary intake over the past year, the food frequency questionnaire (FFQ) was used. The relationship between carbohydrate, fiber, and simple sugar intake with premature heart disease was investigated using simple and multiple logistic regression with adjustment of confounding variables.

The mean age of the subjects was 51.13 ± 6.90 years. There was no significant association between dietary carbohydrate [odds ratio (OR): 1.22, 95% confidence interval (CI): 0.72-2.07], fiber (OR: 0.94, 95% CI: 0.63-1.41), and sugar (OR: 1.35, 95% CI: 0.96-1.90) with incidence of premature heart disease after adjusting for the variables of age, sex, smoking, physical activity, education, job, family history of heart attack, daily energy intake, and body mass index (BMI).

Our results suggested that dietary carbohydrate, fiber, and sugar were not associated with the risk of premature heart disease.
