You guys should watch the film What the Health. It is on Netflix (last I looked at least)
It said that the American Heart Association, American Cancer Society, similar organizations are largely funded by the meat and dairy industry.
meat and dairy isn't required to live a healthy lifestyle as evidenced by all the vegan bodybuilders and professional athletes out there.
in the same film, a woman who could barely walk and was largely dependent on meds, went vegan and was able to walk without a walker after 2 weeks, and no longer needed meds.
The best part about that film had to do with the economic and environmental aspects of meat, corruption in food industries, shadiness of some of the big medical names, and following the money trail.
The vegan healing stuff seems hokey and fake. I did a lot of research and I don't think it's totally out to lunch now. My doctor told me they do prescribe plant based diets to reverse coronary artery disease. How effective this is relies entirely on how compliant the patient is in their diet and keeping animal products of all kinds out of it. People that stick with it can actually get off of some medication that is otherwise required for life (statins). It's very interesting.
most of the nutrition that people are getting from animals was originally sourced from plants anyways. you're bypassing the middleman if you just eat the plants.
the only thing you're not getting is B12 and you can get that in pill form (sourced from non-animals)
Those animals are getting it from supplements too! So just take them yourself.
I supplement D3 as well because I live far enough North that the workday is longer than daylight for a few months a year. No sunshine for me! ---
