According to Impossible Foods, one 4-ounce Impossible burger patty contains 240 calories, 19 grams of protein, 9 grams of carbohydrates (3 grams of which are fiber), and 14 grams of fat (0 grams of which are trans fat).
Compare that to one 4-ounce grass-fed burger patty, which, according to the USDA, contains 224 calories, 22 grams of protein, 0 grams of carbohydrates (and so 0 grams of fiber), and 14 grams of fat (0.8 grams of which are trans fat, but the natural kind, and yes there are natural forms of trans fat).
So is the Impossible burger healthy? Sure. Is it healthier than a grass-fed beef burger? Well, no. Because theres nothing really all that wrong with the occasional grass-fed beef burger either.
Oh there is something hugely wrong with beef to the left.
That is why all of them and not just the left desire to get rid of beef, and why getting rid of cattle has been on their agenda since the seventies.
