In this brief monologue, Dr. David Perlmutter addresses the question of whether any grains can be considered healthy. He argues that most modern grain foods—including quinoa, spelt, amaranth and other trendy varieties—are high‑carbohydrate foods with a relatively high glycemic index, causing blood‑sugar spikes 90–120 minutes after consumption. He claims these spikes are detrimental to brain health. Perlmutter also raises concerns about the non‑organic nature of many grain products and the potential for genetic modification in some grain varieties. Concluding, he recommends a complete avoidance of grains as the safest approach for protecting the brain.
