A whole food, plant-based, and naked nutritional approach doesn’t include any animal-derived foods; therefore, it is vegan. However, the point is to eat whole foods, not vegan processed foods. Some common processed potato chips, cookies, and cereals are vegan, even though they contain loads of refined sugars and flours, oils, sodium, genetically modified ingredients, chemicals, etc.
Whole foods can be enjoyed raw or cooked.
As far as the vegetarian concept, the original meaning of the word supports the consumption of plants, though, in modern day lingo, vegetarian foods include milk, cheese, and eggs, which are as damaging and unsustainable as meats. Therefore, the naked food approach is not vegetarian, but whole food, plant-based, and vegan.
