Other preservatives and chemical food additives can trigger asthma in some children.

Food allergies and asthma

Appropriate physical activity is also vital, thus try to cultivate some family activity time outdoors or at the local gym so that it will be more fun such as skating, basketball or cycling.

Always encourage the child to eat a healthy, whole-food diet with focus on nutrient-dense foods such as vegetables, fruits, whole grains, legumes and healthy fat and protein sources.

Along with the prescribed medications given by doctor, avoidance of these foods can help minimize the occurrence of asthma attacks.
