A new study has found that low fiber consumption is linked to the presence of unstable or high-risk plaque in coronary arteries — the type of plaque that can trigger blood clots and cause heart attacks. The multi-center study led by researchers at Lund University, Sweden, also links dietary patterns to the composition of the plaques, or how potentially dangerous they are. Using advanced cardiac imaging, namely computed tomography, the researchers examined the presence and type of plaque and showed that dietary patterns affect atherosclerosis (the atherosclerotic plaques) in the coronary arteries.
