This study, published in the journal Circulation, suggests poor lifestyle is a major factor that cuts American lives short. Only 8% of the general population followed all five healthy habits. The research focused on the US population, but Stampfer said the findings applied to the UK and much of the western world.
The five healthy habits were defined as:
having a body mass index between 18.5 and 25;
taking at least 30 minutes of moderate exercise a day,
having no more than one 150ml glass of wine a day for women, or two for men;
having a diet rich in items such as fruit, vegetables and whole grains and low in red meat, saturated fats and sugar.
