how whole food plant based is different from veganism

Whole food refers to the state of the food. Food in its most natural form, unrefined and unprocessed (or very minimally processed considering washing, chopping, and steaming veggies can be considered a form of "processing"). The dictionary definition of "process" is "to perform a series of mechanical or chemical operations on something in order to change or preserve it." Unprocessed food has nothing bad added and nothing good taken away. Processed food is easy to spot because it will come in a box or package and have a long list of complicated ingredients with artificial colors, flavors, preservatives and a bunch of other added unnecessary ingredients. Whole foods include grains, fresh fruit and vegetables, legumes, nuts and seeds all in their whole and most natural form. This would also include milk fresh from a healthy cow, a free range chicken egg, a wild caught fish, etc.

Plant based refers to the food itself. Food comes either from the ground or from an animal. All food items can be traced back to their plant or animal origin. Plant food excludes all animal based foods, sounds simple enough, right? Fruits, vegetables, grains, nuts, seeds, beans are all plant foods. Corn syrup, cane sugar, Oreos, and even some cakes and donuts are technically plant based (if they contain no milk, eggs, or other animal byproducts). Other animal byproducts which may not be obvious would include gelatin (made from animal bones), lard (animal fat), lactic acid (from animal muscles and blood - but is also found in beets), casein (a dairy milk protein), rennet (from calf stomach mucus), and many more.

"Vegan" and "whole food plant based" are not the same, although they can be seen as pretty similar. A vegan eats entirely plant based, but not necessarily whole food. Plant based does not always mean whole food and vice versa. The terms vegetarian and vegan primarily refer to what somebody doesn't eat: any food product that is derived from animal origin. While the term whole food plant based refers to what somebody does eat: vegetables, fruits, whole grains, nuts and seeds, legumes in their most whole and natural forms, unprocessed and unrefined.
