Watch this documentary with your thinking hat on.
Look at the cheese brothers. The brother on the vegan diet looked like he needed a ham sandwich desperately by the end. Bags under his eyes, loss of colour in his face, clearly less energy than his brother and looked depressed and admitted it on camera.
They deliberately left out that the men on vegan diets almost certainly were suffering from ED by the end, notice how they presented and suggested the women had increased sexual libido but did not comment on the men in the study? Hmm, I wonder why? Is it because they pumped them full of estrogen in the soy products?
This is political propaganda presenting very cheery picked info.
Uncreative from a film making POV, just like every other "save the planet" content you see. You could swap this series out with Cowspiracy and not notice the difference.
