Important Notes

It is important that subjects are able to get in contact with their study PRA/coordinator whenever there is a scheduled diet pick‐up. Without this contact information, problems cannot be resolved as they arise. In this situation, subjects will be instructed to leave a message for the study PRA/coordinator who will reschedule the subject. Under these circumstances, we cannot reschedule the subject without the standard notice (greater than seven business days).

If a subject is unable to make a scheduled pick‐up, please alert the CTRC Metabolic Kitchen staff as soon as possible by calling 720-848‐6677. The CTRC Nutrition Services is closed on all CU Anschutz Medical Campus holidays and for a short period of time between Christmas and New Year's day. It would not be economical for us to remain open, as few individuals wish to be on study diet during this holiday period.

We are also closed any time the Anschutz Medical Campus is closed for inclement weather or other emergency situation.

Diet pick‐ups may be scheduled the first business day following a holiday, after 12:00pm.

CTRC Scheduler

To ensure compliance to the metabolic meal plan, research subjects must be willing to eat all of the foods provided for them. Therefore, each diet plan contains food items specific to the preferences of the individual. The CTRC Nutrition Services uses an online survey in REDCap to collect this information from the research subject.

Gluten Free Information and Resources

Celiac Disease

The universal treatment for celiac disease, and the only known cure, is a strict exclusion of all wheat, barley, and rye from the diet. Adherence to a gluten free diet helps children grow and maintain a healthy weight, as well as increasing their quality of life. A lot of the complaints about following a gluten free diet stems from a desire to have normal bakery goods. The fact is that even though it is possible to make gluten free breads and cakes, they may never have the same texture as those products which contain gluten. However, it is possible to have a delicious gluten free diet! In this section you will find a number of different recipes and other helpful resources.
