According to a recent study from the University of Washington School of Medicine, eating refined grain products like white bread and white rice is equivalent to eating a diet high in sugars and oils and is linked to an increased risk of developing early coronary artery disease, while whole grain consumption reduces these risks.
According to the study, refined grains are milled into flour to extend its shelf life, which results in the loss of significant nutrients.
The current study used coronary angiography, a diagnostic medical procedure to find restricted blood flow to the heart, on a sample of patients with early coronary artery disease to reveal the relationship between consumption of refined and whole grains and the risk of developing early coronary artery disease in males under 55 years of age or females under 65 years of age.
In addition to a control group of 1,168 people with healthy coronary arteries, the study included 1,369 patients with at least 75% stenosis in at least one coronary artery or at least 50% obstruction in the left main coronary artery. A questionnaire was filled out by study participants to gauge their eating habits.
After controlling for confounding factors, the researchers discovered that consuming more refined grains was linked to a higher risk of heart disease, whereas consuming more whole grains was inversely linked to a lower risk.
