The study will be presented at the American College of Cardiology Middle East 2022 Together with the 13th Emirates Cardiac Society Congress, in Dubai on October 7-9, 2022. Participants answered a food frequency questionnaire to determine how often they ate whole and refined grains.Ī higher consumption of refined grains was linked to a higher risk of PCAD, while eating more whole grains saw a reduced risk.ĭr Gaskarei said: ‘As more studies demonstrate an increase in refined grains consumption globally, as well as the impact on overall health, it is important that we find ways to encourage and educate people on the benefits of whole grain consumption.’ The study looked at 1,168 healthy patients and compared them to 1,369 patients with coronary artery disease. Many crackers, puddings and pastas are also made with refined grains. This is done to extend shelf life, but means the grains lose key nutrients in the process. Whole grains, such as brown rice, oats and whole-wheat bread, contain the entire grain, whereas refined grains have been milled, meaning they have been ground into flour or meal. Over time, high blood sugar can damage blood vessels and the nerves that control the heart and cause plaque to form in the artery walls. Refined grains are broken down rapidly by the body because they have been stripped of fiber, which leads to a post-meal spike in blood-sugar levels. ‘A diet that includes consuming a high amount of unhealthy and refined grains can be considered similar to consuming a diet containing a lot of unhealthy sugars and oils,' he said. Lead study author Dr Mohammad Amin Khajavi Gaskarei said the damage done by a diet high in these grains was similar to eating lots of junk food. They found those who ate refined grains - processed to give them a finer texture and longer shelf life - were more likely to develop coronary artery disease in middle-age. Researchers in Iran looked at the risk of heart disease among people whose diets were high in refined grains compared to whole grains. Eating lots of white rice is just as bad for your heart in the long run as consuming lots of candy, a study suggests.
