So remember studying for Step 1 and having to know that vegetarians are at an increased risk for B12 deficiency? Well, I came across an article talking about the benefits of soy beans. If fortified w/cobalamin as some soy products are, it looks like being a vegetarian isn't so "risky" and actually beneficial.
To make this article peds related...I found it interesting that babies on soy formula can have decreased absorption of iron or thyroid hormone supplementation. Furthermore, soy contains tyramine so could cross react with MAOI's.
Key points from article:
Advantages:
-reduce cholesterol, LDL, and TG levels.
-reduce menopausal hot flashes
-reduce bone turnover-->improve bone mineral density
Disadvantages:
-diarrhea (common)
-Rare:menorrhagia, amenorrhea, HA, dizziness, MSK complaints
Article from American Family Physician, Vol 79, No. 1, Jan. 1, 2009

This is a blog that I hope will be a resource for medical students and residents who are learning to navigate the literature. I plan to post abstracts and brief opinion/discussion pieces related to articles chosen based on patients I take care of. I will also, when possible, outline my search methodology and provide a link so that people who are logged in through OSU's library system are able to quickly obtain the PDFs. If you know of a pertinent article, PLEASE comment with a citation or link.

Interesting. I'll give it a read once OSU's electronic journal section brings us into 2009. As I recall, it is vegans in particular who are at risk for B12 deficiency over their less picky vegetarian counterparts.
My favorite B12 supplement, is of course vegemite . For those that haven't tried it, it is a tasty yeast extract from Down Under. An Aussie taught me how to eat it on bread with a bit of cheese.
