By only looking at a boolean "contains all the things your body needs", you can argue that beef patty topped with a cup of sugar is exactly as healthy.
Sure. But cooked meat also generally does not contain anything that is especially bad for you like sugar. Unprocessed meat is a healthy thing to eat. It’s not that controversial. If you’re eating meat and some vitamin c you’re not going to be deficient in anything.
There are plenty of fine vegetarian options too of course. Although some people will struggle with anemia and protein deficiency.
