Why should whole grains be part of a heart-healthy diet

Healthy eating is known to stave off heart disease and cancer.

But research now shows it also promotes good respiratory health.

Eating oats, wheat, rye, bulgur wheat, polyunsaturated fats and nuts – while reducing red and processed meat, refined grains and sugary drinks – will help beat the killer condition.

Obstructive pulmonary diseases like emphysema and bronchitis block airways and restrict oxygen flow in the body.

Lung disease is the third leading cause of death worldwide and more than three million Britons suffer from it, although most are undiagnosed.

Smoking is the main factor but up to a third of sufferers have never touched a cigarette, says a study in the British Medical Journal today.

Common foods with whole grains are wholewheat bread and pasta, rolled oats and popcorn.
