Nutrient-rich diets increase food security, only if proper water quality is guaranteed

In areas with poor water quality, often in the global South, the promotion of nutrient-rich diets with perishable foods like fruits, vegetables and fish, can deteriorate food safety.

This is due to poor quality water resources from irrigation water, water used in food processing and the way meals are prepared. To ensure nutrient-rich diets, an integrated approach which combines food system and water system thinking is needed.
