Dame Sally Davies, Chief Medical Officer, the 'nation's doctor', has a strategy for our children.

''In the last year of primary school, on average, six children out of a class of thirty are obese and a further four are overweight, twice as many as thirty years ago''. Grim reading.

Children are now drowning in a sea of unhealthy food options and opportunities to be active, and with the Government ambition to half childhood obesity by 2030, means health, not profit need to be made a focus.

Sally includes ten detailed action points to call on politicians and policy makers to make urgent and bold change, with schools and nurseries having a central role in supporting change. She believes the free school meal allowance value should be increased to meet the rising costs needed to provide healthy meals.

Here are Sally's ten tips:

• Regulate to promote healthy food and drinks.
• Ban the marketing of unhealthy food and drinks aimed at children.
• Don't ban private sector sponsorship and support, but insist on advertising and sales of healthy products.
• Design the built environment to encourage children to be active and healthy.
• Improve exercise and healthy weight in pregnancy, breastfeeding rates, and infant feeding.
• Central role for all schools and nurseries, supported by Ofsted in meeting food, drink and physical activity standards.
• Ensure NHS can deliver what children and families need to prevent, manage and treat obesity.
• Use data to guide practice, for example, promoting early intervention and sharing supermarket sales data with policy makers.
• Protect and prioritise: Children's health and a healthy environment must come up above company profits.
• Develop the evidence base to inform practice and policy.
