The body's protein requirements are usually overestimated based on hearsay and this results in too much importance being given to animal based food. Unless you're a growing child, pregnant, bodybuilder or have a medical condition you probably have plenty of protein without consuming meat, and very likely in the other cases too with a balanced diet. One should pay attention to sugars/fats/micronutrients a lot more.

The silly 'But where do you get your protein?' was repeated so much that it inevitably lead to 'they will give us bugs'.
