Insofar as it isn't recognizably an ingredient that is picked from a field and marketed as a plant or animal part, it's part of what's causing all of us to be really unhealthy in the US.
Again, food-industry trends are best read through the lens of capitalism, not ecology. We’re not taking about eating a bowl of beans.
If you want to eat less meat for other reasons then go ahead. But there is no legitimate scientific consensus on this point in the medical profession.
They aren't. Majority of meat products are also heavily processed and far from being healthy food. Sausages, cutlets, etc. The only good meat is some cut that you cooked yourself.
So from the health perspective there isn't much difference between processed meat and processed vegetables. Both aren't good for our guts. Sadly, buying unprocessed food and/or cooking is often more expensive and not scalable to cover every single individual or family on this planet.
I've heard this line a few times, and people say it as if there will be billions more people starving in Africa if processed foods didn't exist. This simply isn't true though, processed foods are only an issue in highly developed countries.
In developing countries poorer people eat very few processed foods. Why? Because it's cheaper to buy raw foods. People eat what is in season and often what they can grow themselves or some neighbour has grown. Yes they probably eat something similar every day, but so what, it works for them.
I live in a small, not terribly well off, European country where meals are typically prepared from scratch. In the supermarket the most processed food you will find is a chocolate bar or a bag of crisps. We don't have 'ready meals', if you want to eat say a fish pie, you need to buy the raw ingredients and make it yourself from scratch.
I make an omelette for breakfast every day which involves a bunch of preparation, mixing and cooking, but when eating it's easy to identify the ingredients - this is a piece of pork, that's a radish, that's a piece of garlic etc. The closest thing to food product is some ground-up red pepper and other herbs that are there to modulate the flavor, but don't make up the main substance of the dish.
I've thought about buying some of these meat substitute products a few times, but for one thing they're quite expensive and for another when I look at the ingredients I can't easily conceive of what went into the product or how. I know vegetarian and vegan food can be delicious and nutritious thanks to friends who are great cooks, but again when I eat their cooking I can easily identify what I'm putting in my mouth.
I don’t believe for one second that you cannot distinguish between salad and things like Huel.
