Certified nutritional therapist Natalie Peltro shares the food-recovery framework she built after her son, diagnosed with severe nonverbal autism at 18 months, would eat only three foods. She breaks down the biology behind picky eating, including taste sensitivity tied to nutrient deficiency, and introduces her “Four E’s” framework — Expectation, Emotional Intelligence, Environment, and Encouragement. The conversation offers practical, pressure-free strategies for expanding a limited diet in both kids and adults.
