Remove the word "vegan" from your article and replace it with "all" and you have provided a public service- animal based proteins are more deficient than plant based proteins- more damage is being caused by fast food and animal proteins than any plant based diet. It isn't even up for discussion its science. This feels like a meat industry propaganda piece- are you a PR for that industry or have some share or stake holder interest?

I am sure if we scratched the surface we would find not that the couple in question caused malnutrition do to forcing a vegan diet but that they were just plain negligent. Fear and misinformation makes great propaganda.
