Healthy nutrition is an essential element for individuals with autism spectrum disorder (ASD), but dietary needs vary from person to person.

Due to selective and improper eating habits, individuals with autism may experience obesity or malnutrition. Additionally, special diets may lead to weight fluctuations, making it crucial to monitor body composition throughout the process.

In cases where autism is accompanied by neurological disorders such as epilepsy, a ketogenic diet may be recommended. Similarly, in metabolic disorders affecting protein metabolism, diets that restrict natural protein intake may be necessary. There are various dietary approaches for individuals with autism. Such as a Gluten-free diet, Gluten-free and casein-free diet, Ketogenic diet, Specific carbohydrate diet, GAPS diet, Feingold diet, etc.

The necessity of a special diet for an individual with autism is determined based on the following factors:

• Body weight and height assessment according to age
• Body mass index (BMI)
• Eating behaviors
• Coexisting neurological disorders (e.g., epilepsy, cerebral palsy)
• Coexisting metabolic disorders
• Coexisting genetic conditions
• Digestive system health (e.g., gut permeability, constipation, diarrhea)
• Food allergies and intolerances

A personalized nutrition plan is developed based on an evaluation by a nutrition and dietetics specialist.
