To guide you through heart health we've asked Dr Chris Steele to explain the science behind heart health. Dr Chris Steele has been a resident TV Doctor for 17 years on ITV's 'This Morning'. He has written extensively - nationally and internationally - both on general medical issues and smoking cessation, and has published two books on quitting smoking, and on babies and young children.
