Oct 3 (UPI) – A new study reports that eating a lot of refined grains, such as white bread and white rice, is similar to a diet full of sugars and oils, and is linked to an increased risk of early coronary artery disease.

In contrast, eating whole grains, such as whole-grain bread, whole oats or quinoa, was associated with a lower risk of early coronary artery disease, according to the study.

A press release about the study was issued on Monday in anticipation of its presentation at the American College of Cardiology Middle East 2022 in partnership with the 13th Emirates Heart Association. Congress To run from Friday to Sunday in Dubai, United Arab Emirates.

Whole-grain foods contain the whole grain kernel, while refined grains are ground into flour or flour to improve shelf life. The Cardiology Group confirmed that refined grains lose important nutrients in the process.

2019 ACC / American Heart Association Guide to primary prevention of cardiovascular disease He recommends a diet that emphasizes vegetables, fruits, legumes, whole grains, and fish to reduce heart disease risk factors.

The new study explored the link between consumption of whole and refined grains and the risk of early coronary artery disease — defined as narrowing of the coronary arteries in males under 55 years of age or females under 65 years of age — in Iran.

“A diet that includes the consumption of a large amount of unhealthy and refined grains can be considered similar to consuming a diet that contains a lot of unhealthy sugars and oils,” Dr. Muhammad Amin Khajafi Gaskari, the study’s lead author, said in the statement.

Gaskari, of the Isfahan Cardiovascular Research Center and Institute of Cardiovascular Research at Isfahan University of Medical Sciences in Isfahan, said that people may consume more refined grains than whole grains due to factors such as economy, income, job, education, culture and age. Iran.

Smoking, high cholesterol, high blood pressure and diabetes are risk factors for early coronary artery disease, which often begins without symptoms but can lead to chest pain and/or heart attack from narrowing or rupture of plaques in the arterial wall, the statement said. .

The study recruited more than 2,000 people with early coronary artery disease from hospitals with catheter labs across Iran who underwent coronary angiography, a diagnostic medical procedure that looks to restrict blood flow to the heart. women were 70 years of age or younger; The men were 60 years of age or younger.

Ultimately, the research included 1,369 patients with at least 75% blockage in at least one coronary artery or at least 50% in the left main coronary artery, along with a control group of 1,168 patients with normal coronary arteries.

Participants completed a questionnaire to assess their eating behaviors.

After adjusting for confounding variables, the researchers determined that a higher intake of refined grains was associated with an increased risk of heart disease, while an intake of whole grains was inversely associated with a reduced risk.

“While more studies show an increase in consumption of refined grains globally, as well as an impact on public health, it is important that we find ways to encourage and educate people about the benefits of consuming whole grains,” Khajavi Gaskari said.

That strategy, he said, should include ongoing research on the topic, “teach improved food choices in schools and other public places,” and have clinicians discuss the advantages of whole grains with their patients.
