A healthy heart 
Our arteries circulate blood around the body and are essential to good health, but the blood 
flow can be impeded1 by fatty plaque2 that can clog3 them. The production of plaque is 
associated with high levels of cholesterol4 and clogged blood vessels can lead to a heart 
attack or a stroke5. Some foods, such as eggs and shellfish, while nutritious6, are 
also cholesterol-rich, but, if eaten in moderation, do not significantly raise cholesterol 
levels or pose a danger7. ‗Bad cholesterol‘ is counteracted by fibre8 in our diet, and 
a high-fibre diet is often recommended by health experts. Fibre causes less fat to be 
absorbed by the blood vessels. Fibre rich foods include fruit, 
vegetables, lentils9, oatmeal10, potatoes and wholemeal bread.
