In most cases, humans don't need to eat meat/fish to have a healthy diet, a vegetarian diet is more than enough to sustain a healthy human body. Most humans are doing a omnivorous diet for traditions (and because taste delicious) without too much thinking in the unnecessary suffering of animals.
We recommend a diet that is benevolent (ethical assimilation of food), usually it is a vegan diet (even better without eating roots of the plant) or a vegetarian diet that it is respectful with animals and plants.
We desire to have better energetic systems than the human digestive system and related systems.
