You know food deficiencies are very common among average americans as well right? Even the B12 defeciency which is the only consistently recorded deficiency among vegans, is VERY common amongst omnivores.

I am getting my blood tested regularly and all of my values are absolutely perfect. Sure if you're planning on eating only vegan junk food you're going to encounter deficiencies, but don't tell me it would be any different if you only ate at MC Donalds.
