Researchers performed CT scans and collected data on more than 3,000 men and women with an average age of 40 and found that individuals with any calcified plaque in their arteries had a five times greater risk for cardiovascular problems. Furthermore, these individuals had a three times increased risk for a heart attack or stroke. Northwestern University’s Dr. Philip Greenland comments, “The fact that arterial blockages can occur in such young adults reinforces the need for much younger people—like teenagers and 20- to 30-year-olds—to follow healthy exercise and eating habits and not smoke.” JAMA Cardiology, February 2017
