Behavioural interventions focus on the adjustment of personal practices and habits. Adding nutrients to staple foods is termed fortification, while supplementation refers to the provision of individual or mixtures of nutrients separately from the diet.

Nutrition interventions that take place in a specific setting are categorized as situational health actions. Other health-related interventions, such as deworming, also have an impact on nutrition.
