Vegan diets are based on grains and other seeds, legumes (particularly beans), fruits, vegetables, edible mushrooms, and nuts. Meat analogues (mock meats) based on soybeans (tofu), or wheat-based seitan/gluten, are a common source of plant protein, usually in the form of vegetarian sausage, mince, and veggie burgers.
To start on a plant-based diet, keep it simple. Begin by cutting out one animal product at a time. First, replace all milk and dairy products with soy, rice, almond and hemp alternatives. Use vegan cheeses, soy or rice yogurt, âvegannaise,â soy or coconut-milk coffee creamer, vegan sour cream, etc.
