Vegan?

1. Being a vegan is fine and respectable. Just make sure that you are planning it correctly and not relying on YouTube or even Dr. Oz for your information. Here are a couple of reputable resources to start with:

Being a vegan is totally healthy if planned appropriately. I can trust Harvard and the ADA. Money quote:

"In July 2009, the American Dietetic Association weighed in with a position paper, concluding that "appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases" (Journal of the American Dietetic Association, July 2009)."

And this:

"The Institute of Medicine recommends that adults get a minimum of 0.8 grams of protein for every kilogram of body weight per day (or 8 grams of protein for every 20 pounds of body weight)."

2. DO NOT start any kind of vegan diet with your kid without talking this over with your pediatrician. My hunch is that the pediatrician will tell you it is a bad idea and then give you a bunch of reasons why. Remember that breast milk is an animal-based source of nutrition! At some point towards our middle age we just need less animal protein than before, but for kids ask yourself if it is a health risk you are willing to take.

Hope this helps.
