You can eat all kinds of things without torturing the animals - if you have no alternative please explain clearly why, why eating meat is important enough, and convince - actually absolutely nobody, nobody in power cares about animal suffering in our food system.
And before you ask, no not everyone has to eat meat, but, there is at least the reason that an all plant diet is intractable to some people for the sheer amount of carbohydrates, and for others due to the mental load of making sure they get the nutrients that are hard to get in plants but easy to get in meat.
But it's probably also more convenient to do drowned rat studies to figure out specific things than it is to construct more elaborate ones to ascertain the same kinds of findings. So I don't think my take is that far off the mark, still.
This isn't true,as proven by the many laws and regulations about it for decades.
