Raw veganism is a diet that combines the concepts of veganism and raw foodism. It excludes all food and products of animal origin, as well as food cooked at a temperature above 48 °C (118 °F). A raw vegan diet includes raw vegetables and fruits, nuts and nut pastes, grain and legume sprouts, seeds, plant oils, sea vegetables, herbs, mushrooms, and fresh juices. There are many different versions of the diet, including fruitarianism, juicearianism, and sproutarianism.
In addition to the ethics of eating meat, dairy, eggs and honey, raw vegans may be motivated by health, spiritual, financial, or environmental reasons, or any combination of these.
In terms of health, some raw vegans hold the belief that cooking foods destroys the complex balance of micronutrients. They may also believe that, in the cooking process, dangerous chemicals are produced by the heat interaction with fat, protein, and carbohydrates such as advanced glycation end-products (AGEs) and others..
Other followers of a raw vegan diet place importance on spiritual gain. For example, Ruthann Russo, Ph.D, (author of two books on the raw foods diet) says that the movement aims to look at "the way food, living, treatment of the earth, our treatment of each other, and our quest for physical, spiritual, and mental health all fit together."
Forest gardening is a radical raw vegan lifestyle with a number of motives. For example, it can be viewed as a way to recreate the Garden of Eden. Developed by raw vegan Robert Hart, forest gardening is a food production system based on woodland ecosystems, incorporating fruit and nut trees, shrubs, herbs, vines and perennial vegetables. The three main products from a forest garden are fruit, nuts and green leafy vegetables. Forest gardens are probably the world's oldest and most resilient agroecosystem.
