MIAMI:- People who skip breakfast or eat poorly to start the day are twice as likely to develop hardened arteries, which can lead to deadly heart disease, researchers said. The study in the Journal of the American College of Cardiology uncovered signs of damage to the arteries long before symptoms or disease developed. Researchers said their findings could offer an important tool in the fight against cardiovascular disease, the world’s top killer, which took 17.7 million lives in 2015, according to the World Health Organization.
