American has a rich, diverse, and passionate food culture that includes many whole foods and innovations created there. A lot of processed food is eaten, but so are a huge variety of unprocessed foods.
Replacing animal products with plant protein (beyond burger, impossible burger, many others) is an excellent trend for many reasons, with the potential environmental impact being the foremost benefit in my opinion. I look forward to the day where lab grown and/or plant protein sources are much more mainstream.
And lastly, "Monsanto soy and chemistry" is a ludicrous implication that plant based protein sources are somehow inherently scary or even that they're worse than mass-agriculture raised animal products.
