A vegan diet, or veganism, tends to omit animal products for ethical, health, or environmental reasons.
Once considered a niche diet, veganism has gone mainstream — so much so that the number of people following a vegan diet has increased by 350% in the last decade, according to research from the U.K. (1Trusted Source).
By definition, veganism is a way of living in which people exclude, as much as possible, all forms of animal exploitation and cruelty.
At first glance, a vegan diet may seem complicated or overly restrictive. Many of my clients who are considering switching over to a vegan diet are initially worried about finding suitable vegan alternatives to their favorite meals.
