This restrictive, Buddhism-inspired eating plan focuses on locally grown produce, whole grains, legumes and bean-based products like tofu, tempeh and miso. Seafood, fruit and nuts are allowed a few times a week. Spicy food is off limits. Meat, dairy, refined grain and refined sugars are out, as are any processed foods, including those that are canned or frozen.
