Nutritional Guidelines

Nutrition plays an important role in overall health and function. Given the wealth of information available about nutrition, diets, vitamins and supplements, distinguishing between speculation and science-based facts can be challenging.

In an effort to facilitate access to unbiased, scientifically-validated information on vitamins, supplements and other aspects of well-rounded nutrition, we have compiled the following list of resources.

Vitamin Intake

Recommended daily intake ranges for most common vitamin and mineral supplements, based upon scientific data and disseminated by both the NIH and USDA.

Super Tracker

An online tool available from the USDA to help plan, analyze and track your diet and physical activity.

Digestive Health Guide for People with Recurring Bowel Obstructions

Compiled by Clear Passage, this guide includes food guidelines, diet tracks and recipes for those suffering from recurring bowel obstruction and other adhesions-related digestive disorders.

The Guide is a collection of suggestions from various sources that patients with these conditions have found beneficial. This information is not a substitute for the advice of your dietician or nutritionist. 

Herbal Supplements

We want to ensure that those considering taking herbal supplements have access to accurate, science-based data. The National Institutes of Health provides scientifically analyzed information about herbal supplements, their efficacy for a wide variety of conditions, and associated cautions and interactions.


Probiotics are beneficial for patients suffering from gut and/or bowel-related inflammatory diseases that can be partially or fully attributed to imbalances in the bacterial flora in the bowels. We do not recommend one brand of probiotic over another. However, we feel that the following criteria — based upon the current literature — are most important to consider when selecting a probiotic:

  • A minimum of 10 bacterial species
  • A minimum of 10 million cfu per dose
  • The absence of all fungus or yeast species including Candida and Saccharomyces
