Eat your greens!

People who ate large amounts of fruit and veg in their early 20s were found to be a quarter less likely to have blocked or restricted arteries in their 40s.
Having arteries partly blocked by plaques is a condition known as atherosclerosis. It is a potentially life threatening condition as the plaques cause affected arteries to harden and narrow, which can dangerously restrict blood flow damaging organs and stopping them functioning properly.

If a plaque ruptures, it can cause a blood clot which blocks the blood supply to the heart, triggering a heart attack, or it can block the blood supply to the brain, triggering a stroke.

Previous studies have shown the benefit of a diet rich in fruit and vegetables reduces heart disease risk among middle-age adults but the new study is the first to examine whether eating more fruits and vegetables as young adults could produce a measurable improvement in the health of their heart and blood vessels years later.
The Minneapolis Heart Institute in Minnesota found those who ate such a diet had less calcified coronary artery plaque two decades later which can be measured in CT scans.
