People-Planet-Health: promoting grassroots movements through participatory co-production.

The threat of anthropogenic climate change demands immediate action to prevent further damage to human health and fragile natural ecosystems. This process of change might locally have already begun, led by grassroots organisations around the world. Conceiving their actions as a form of salutogenesis, these organisations build a Sense of Coherence to empower communities to participate in the potentially overwhelming challenge of planetary health. People-Planet-Health aims at giving voice and visibility to those groups and their actions. Contributors will further be invited to co-create a position paper, to inform the revised WHO Global Strategy for Health Promotion.

Changes in the nutritional content of children's lunches after the Food Dudes healthy eating programme.

Previous research into the effectiveness of healthy eating programmes has shown increases in healthful eating behaviour in primary schools; however, data collection methods have not been sufficiently sensitive to detect micronutrient changes. The present study extends the literature by measuring individual children's intake of macro- and micronutrients at lunchtime, before and after a programme targeting children's consumption of fruit and vegetables, to identify evidence-based health benefits of programme participation. Baseline data were collected over 4 d at lunchtime in two primary schools. The Food Dudes programme was then implemented in the intervention school. Follow-up data were collected over 4 d in each school 2 months after baseline. We employed a validated and sensitive photographic method to estimate individual children's (N 112) consumption of fruit, vegetables, and their intake of calories, macro- and selected micronutrients. Significant changes were observed in the intervention school but not in the control school: Children's consumption of fruit, vegetables, vitamin C and E intake increased, while their total energy consumption, fat, saturated fat, and sodium intake decreased. The present results show that the Food Dudes programme produced a positive nutritional change, with implications for its application as a healthy eating and obesity prevention intervention. These optimistic conclusions should be tested by further research to establish the longevity of the positive effects presented here.
