The Vegan Digest supplements its publication #5 article on product inputs and shares 100 plant-based commodities or minimal, value-added products. Each item on this list, excluding beer, wine, and spirits, contains nutritional proteins and is typically not attributed to vegans as much as intentionally excluded foods like artichokes, aubergine, beets, radish, seitan, tempeh, tofu, turnips, and zucchini. Non-plant additives such as salts and water are excluded, while mushrooms are included as a vegan item due to their high nutritional protein value. Some foods are high in water content and thus represent the lower protein density foods listed.
