most vegetarians and vegans have poorly planned diets
Really? I’m neither, but I do question how you can quantify the accuracy of that statement.
Yes, I stand behind the accuracy of that statement. Most vegans and vegetarians have very poor diets. Doctors/dieticians/scientists worry about vegan intake of protein, vitamin B12, vitamin D, calcium, iron, omegas, choline, etc. based on real world examples of what most vegans eat and how most vegans look like and behave. If it was easy, it would not be covered in media all the time.
It is rare for them to hit the RDAs every single day, without going over the limit of some micronutrients, without overconsuming sugar, while still eating a good amount of protein and sufficient fats. Look at their nutrition tracking profiles.
The only way for them to do that would be to consume Huel or some other similar complete food. No other diet than complete foods is able to fit these criteria.
Additionally, there is a massive rise of vegans that eat processed foods, with added sugar, too much salt, too much saturated fat (which is especially bad in combination with sugar). Many new plant-based companies and products are showing up, demonstrating profitability of these products, which correlates to increased consumption of these products.
The few vegans who eat a properly planned whole-food plant-based diet is miniscule. Those of them that manage it usually call themselves plant-based and not vegan because eat that diet for the health benefits (which means they properly studied up on their diet) and not for ethical reasons.
I know many omnivorous who eat tons of junk food, literally the worst people at planning dieys ever.
My statement was only about vegetarians and vegans. Just because vegetarians and vegans have poor diets does not mean that omnivores have good diets.
