Find inspiration from traditional cultural diets. Many traditional eating patterns from around the world are primarily a plant-based diet. In some regions of the world, like the Mediterranean or Africa, patterns of eating may include small amounts of animal products, but they are used in smaller portion sizes and less frequently throughout the day or week. The diet is based on a pyramid of plant foods.
Our challenge will be using all vegetarian and vegan recipes and encouraging people to try plant-based sources of protein, iron, and calcium. If you eat meat or animal products with no intention of excluding them during the challenge, we suggest challenging yourself to think more about the frequency and portion sizes of the meat and animal products used. Following one of the other heritage pyramids, such as the Mediterranean or African style, would be a great place to start.
