It shouldn't have been, because many plant-based dishes do not include the same amount of nutrients if they are cooked as opposed to consuming the raw vegetable ingredients, and people are either unaware of this entirely or completely neglect taking it into account in regards to actual nutritional value. That's before we even address nutrient bio-availability of ingredients pre-and-post preparation. You will always see tons of people crow about how many vitamins and other nutrients certain foods have, but they rarely if ever mention that with many of them you'd have to eat a dump truck full of it to even approach your daily recommended value because your body simply refuses to process much of it and passes it on as waste.
