Skipping breakfast could raise your risk of heart disease by 87 percent, according to a new study.

Researchers at the University of Iowa analyzed 18 years of data on 6,550 people over 40 who had no history of heart disease. They were given regular surveys, which included the question: how often do you eat breakfast? Most (59 percent) ate breakfast every day, but 5.1 percent never did, 10.9 percent rarely did, and 25 percent would skip a few days. The team found a clear link between breakfast habits and heart disease risk. Those who didn't eat in the morning were up to 87 percent more likely to develop heart woes.

“Breakfast is believed to be an important meal of the day, whereas there has been an increasing prevalence of skipping breakfast over the past 50 years in the United States, with as many as 23.8 percent of young people skipping breakfast every day,” the authors write. “However, studies on the health effects of skipping breakfast are sparse.” To their knowledge, this is the first retrospective study to look at breakfast habits and cardiovascular mortality.

The team pointed to a few factors which could underlie this connection. First, those who don’t eat breakfast may be more likely to snack unhealthily. Second, breakfast may help to balance blood sugar levels and control blood pressure.

The findings, published on the American College of Cardiology, come days after a similar study showed people who skip breakfast and eat a late dinner are less likely to survive a heart attack. Those who didn’t eat breakfast were more likely to smoke, scrimp on exercise, and drink alcohol.
