Introduction
In general, diet cannot cure autism spectrum disorder (ASD) completely, but a scientific and well-balanced dietary plan can help alleviate certain symptoms and support intervention efforts; the specific effects should be adjusted according to individual conditions. In daily life, patients should be encouraged to develop regular eating habits, with fresh and natural ingredients preferred and cooking methods kept light and mild. Family members may keep records of the relationship between diet and symptom changes.

Generally, diet alone cannot cure autism, but a scientific and well-balanced dietary plan can help alleviate certain symptoms and support intervention efforts. The specific effects vary depending on individual circumstances and require personalized adjustments. Detailed analysis is as follows:

Individuals with autism often experience picky eating or selective eating habits, which may lead to nutritional imbalances and exacerbate issues such as mood swings and difficulty concentrating. Targeted supplementation of high-quality protein, Omega-3 fatty acids, and B vitamins can support improved neurological function. Avoiding processed foods containing artificial colors and preservatives may reduce symptoms of hyperactivity and impulsivity in some individuals. While these dietary modifications do not directly address the underlying causes of autism, they can help optimize overall physical condition.

Dietary interventions should not replace core treatments such as educational training and behavioral therapy. Improvement in autism requires a comprehensive, multidisciplinary approach, and relying solely on diet may delay effective treatment. Furthermore, due to individual differences in physiology, personalized dietary plans should be developed based on professional assessments to prevent malnutrition caused by unnecessary or overly restrictive dietary restrictions.

In daily life, it is important to establish regular eating habits for individuals with autism. Food ingredients should be fresh and natural, with cooking methods emphasizing light and healthy preparation. Family members can keep records of the relationship between diet and symptom changes to provide valuable information for adjusting the dietary plan, thereby helping to improve the individual's quality of life.
