Greens are a source of protein, most whole foods are. But if you ate only greens I highly doubt you'd be able to eat enough calories, and you might run into other issues like mineral toxicity. Calorie bombs get a bad rep but the human diet revolves around them, the problem is many get them in the form of refined sugars and fats.
While it's obvious you are exagerating, no scientist would say that unless it's a "scientist". The right balance of nutrients as an average over time is the correct way.
Yeah. Actual scientists at NASA learned that eating the same gruel every day affected mental health, so folks on the ISS have a pretty varied diet. Even though todays coffee is yesterdays coffee.
Which I think is a good enough excuse to eat more than six fries as a serving.
Cows have four stomachs and rechew their food for hours for a reason. Leafy greens are not proper food. (Plus, they're full of toxins, both from pesticides and from the plants trying to kill anything that eats them, and tasting as horrible as possible to dissuade animals from eating them.)
The only edible parts of the plant are fruits, which are intended for animals to eat them so that they'll spread the seeds.
Still made of undigestable cellulose, toxins, and whatever chemical horrors we've sprayed on top to kill any insect that has managed to evolve a resistance to said toxins.
lmao what the fuck? leafy greens are fine, great even because they're basically just fibre and vitamins which most people need way more of.
yeah, you're not going to get your caloric or protein requirements from spinach, but you should absolutely eat as much leafy greens as you can stomach alongside the spaghetti and meatballs.
