This 25th anniversary edition includes new cooking techniques (think Instant Pot), new recipes, and new research. Special Diets for Special Kids provides delicious ways to package the benefits food can provide for children with neurodevelopmental disorders. Lisa Lewis' short anecdotes at the beginning of many of the recipes make for entertaining reading. Lewis' son has autism and has been on a GFCF diet for many years. The author has a talent for explaining the scientific basis of digestive and absorptive problems in autistic children in ways that are easy for overwhelmed parents to understand.
