The difference between mass-produced almond milk and almond milk you make yourself ought to be a good object lesson. I think to make it you just grind up some almonds in a blender and add water, let it soak a while and strain. (This is from memory from something I read about 20 years ago, so maybe look up the correct process.) The end result will not look or taste the same as the stuff you buy. This ought to tell you that the long list of additives are quite significant to the product.
Try going without any milk or milk-like substance. There is no gaping hole left when you can't drink a glass of milky stuff.
