Why should it only apply for extreme situations?
For the same reason it's only OK to kill other human beings in extreme situations. If you will otherwise die, then you can kill somebody to eat, or in self defense if that person is attacking you. This is justified to protect your life. If you must do something harmful, you can do so and be justified. If you don't need to do it, then the harm is not justified, and your choice to do harm is wrong.

If there are healthy and nutritious ways to eat human meat on a normal basis, is that okay?
It's not a question of whether you can do it, it's a question of whether you need to. And the science says we do not need to.

Well-planned vegetarian diets are appropriate for individuals during all stages of the life cycle, including pregnancy, lactation, infancy, childhood, and adolescence, and for athletes.

That is the scientific consensus on nutrition. It's a simple fact that we don't need to eat animal products to be healthy, and there's no credible evidence that says otherwise.
There is a lot of pseudoscience and quack medicine that claims meat is necessary, don't be fooled by yellow journalism.
It's also true that we don't need to kill and eat other members of our own species to be healthy, and there's no credible evidence otherwise -- despite the fact that our ancestors did it for millions of years.

Because there are balanced diets containing only plants, fungi, etc. Balanced means balanced in terms of nutrition, that is protein (like beans), starches (like whole grains), fats (like nuts). There are many ways to balance a diet, and pig cow or chicken meat is not any more necessary to do so than human meat.
The reason the choice to include meat is wrong is because it's a choice to cause more harm instead of less harm. Because it's a choice. If you didn't have a choice in the matter, then it couldn't be wrong.
