This book takes the readers through several different aspects of vegan food, vegan diets, comparison between veganism and vegetarianism. This book sheds light on the several concepts of vegan food and diet, its benefits, food justice, public health nutrition and the vegan studies in the discipline of religion, the anthropology and archaeology of food and the future of veganism. A healthy, plant-based diet requires planning, reading labels, and discipline. Vegetarian diets do not contain meat, poultry or fish; vegan diets further exclude dairy products and eggs. In general, vegetarian diets provide relatively large amounts of cereals, pulses, nuts, fruits and vegetables. In terms of nutrients, vegetarian diets are usually rich in carbohydrates, n6 fatty acids, dietary fibre, carotenoids, folic acid, vitamin C, vitamin E and Mg, and relatively low in protein, saturated fat, long-chain n3 fatty acids, retinol, vitamin B12 and Zn; vegans may have particularly low intakes of vitamin B12 and low intakes of Ca and vitamin D. This book has been designed to suit the knowledge and pursuit of the nutritionist, dietitian, students, researcher and scholars and to empower them with various aspects of the vegan food so, that they are updated with the information.
