Note on ingredients: Except for coconut, all nuts are considered “suspect” on the Bulletproof Diet because of their high levels of omega-6 fats that can oxidize and contribute to inflammation. Nuts are also susceptible to mold and contain lectins, nutrient-sapping compounds that can be tough on your gut. Use nuts in moderation, or remove them from your diet and reintroduce in small amounts to test your sensitivity.
