Sitting for long hours at work? Scientists reveal simple snacks that could protect your heart from the dangers of a sedentary lifestyle

A new study from the University of Birmingham suggests that flavanol-rich foods such as cocoa, berries, apples, tea and nuts may help protect blood vessels from damage caused by long periods of sitting. In an experiment with 40 men, high-flavanol cocoa prevented declines in vascular function typically seen after two hours of inactivity, unlike low-flavanol drinks. Researchers say diet may offer support even for physically fit individuals and could help counter cardiovascular stress linked to sedentary lifestyles.
