Hi ComfyJoey, are you of the baby carrier ad? Welcome! My family started on our vegan journey for health reasons. Ds was 6wks old, exclusively bf, and had blood in his stool. The ped said its probably a milk allergy and told me to quit consuming dairy. So I did.
Then I started researching how to get calcium and found there are better ways to get it than dairy! I also found info on how animal protein can inhibit the absorption of calcium. Then I found www.drmcdougall.com
. Later I read The China Study by T. Colin Campbell. I got to hear Brenda Davis (vegan dietician) speak! I would encourage you to take a look at some of their writings about the health benefits!
Here we are going on 7 years now! We're currently researching how to healthfully feed a dog a vegan diet, because we really want to adopt from a local shelter.
