I just stumbled across a very informative article (technically a Q&A) written by Dr. Andrew Weil. You probably recognize the name, as Dr. Weil has written many books on health and nutrition, and appears on TV regularly.
His article is about nutrition after weight loss surgery (in this case gastric bypass). Specifically, it explains how you need to optimize your nutrition after weight loss surgery by taking vitamin and mineral supplements, increasing your iron intake, etc.
Here’s an excerpt:
“Because your body will have difficulty absorbing certain nutrients after the surgery, you will also need to take vitamin and mineral supplements daily. Caroline Apovian, M.D., director of the Nutrition and Weight Management Center at Boston Medical Center, tells me that you’ll need a daily chewable multivitamin plus additional calcium and vitamin D.”
