Through the Partnership for Healthy Cities (PHC) Food Policy, the cities are identifying ways by which their urban population can eat healthy foods in healthier environments.

Ms Ariella Rojhani, Director for the PHC at Vital Strategies, told the press at the PHC Summit in Cape Town that the cities were successfully implementing nutritional measures that was reforming what children ate and drunk in a school environment.

"The cities are enforcing nutritional standards for food served in schools, hospitals and other public places ensuring that only healthy food options are available,she said.

Abidjan, Côte d'Ivoire, and Dakar, Senegal are for instance designing nutrition standards aimed at reducing excessive salt consumption in public schools.

Freetown, Sierra Leone is training market vendors on the dangers of excess salt consumption and on how to bring the information to their customers.

Ouagadougou, Burkina Faso is creating nutritional standards and developing a policy on foods served in schools and hospitals, with a focus on reducing salt and sugar consumption.

Ms. Rojhani said as West African cities experienced epiderniological transition from infectious diseases to chronic NCDs, where cities were observing an increase in stroke, hypertension, diabetes and cancers, enforcing strong healthy food interventions was necessary.

She said through the power of the partnerships, cities were becoming successful by learning from each other and replicating ideas with focus on developing meaningful nutritional standards.

"Cities are putting forward rules that say that food must be limited to fresh products, it must not contain excess salt and sugar," she said.

Ms Rojhani said in Latin America, there had been a huge demand for stronger food policies, as a human right issue, and that people in communities were demanding for healthier food and clean water.
