For every disease or disorder: from diabetes to heart disease, celiac or IBS…food matters.
Hippocrates, the father of modern medicine taught us to “let food be thy medicine” and informed us “all disease begins the gut.” To help heal autism, we must remember these principles and relearn the use of healthy food and nutrition for our children.
Parents report positive changes to health and behavior when applying special “autism diets:” which involve removing offending foods and boosting the nutritious foods children eat. They are realizing that they can affect their child’s health through these calculated omissions and additions to diet. Since parents determine what their children eat, implementing a diet is an empowering step parents can take to help their child(ren) feel better, reduce their autism symptoms, and help them pursue their full potential.
Here is some current knowledge about food, diet, and autism:
- Children with autism have problems with certain foods that affect their behavioral, cognitive, and physical symptoms. 1, 3, 5
- Food has a direct effect on the gut, intestinal inflammation, and digestive capacity – which in turn affects physiology and brain function. 2, 4
- Nutrient deficiencies are common with autism.6, 7, 8
- Gut problems and insufficient digestive enzyme function are common.9
- Digestion, detoxification, and immune function are often affected. Dietary intervention influences these disordered systems seen in autism.
- The gut is considered the “second brain” and the “gut-brain connection has been studied in autism.10 Healing the gut positively influences the brain.
- Addressing digestive issues increases nutrition absorption. As nutrient status improves, systems function better – including the brain.
- Removing foods containing toxins (such as artificial additives) that adversely affect brain chemistry relieves a burden on the liver and detoxification system, and affects improvement in brain function and behavior.11
- By avoiding inflammatory foods (gluten, casein, and others) we support in immune and digestive systems.
When you see how much food matters, it’s easy to understand why most people who try dietary intervention benefit! The Autism Research Institute (ARI) surveyed thousands of parents and found that 69% of those applying the Gluten-free Casein-free Diet saw improvement. For the Specific Carbohydrate Diet, 71% noted improvement. In recent autism diet research funded by Autism Speaks, 82% of parents reported “definite improvement” in their child’s skills. Parents report improvements in eye contact, language, attention, diarrhea, constipation, sleep, hyperactivity, and more.
While “dietary intervention” (change) can seem overwhelming, with learning and focus, even busy moms can, and do, make it work. As a child feels better, parents often have more quality time with their children and cooking becomes more enjoyable. And nutritious meals needn’t cost a fortune. While quality, whole foods involve more expensive ingredients; you’re buying fewer expensive processed foods. A healing diet empowers you to support your child’s health and improved well-being.
This is why I titled my book, Nourishing Hope. We need to nourish children’s bodies with healthy food, and nourish our minds and souls with hope. Food nourishes the body, and the positive changes we see nourishes hope. Healthy food preparation even transfers healing energy through the loving intention of the chef. With virtually no downside, everyone should give this a try.

Audhya reported his measurements of vitamin and mineral levels in the blood of over 150 children with autism compared to 50-100 controls of the same age. He found that the children with autism on average had much lower levels of most vitamins (vitamins A, C, D, and E; all B vitamins except choline) and some minerals (zinc; magnesium; selenium).
