Doesn't it seem like when it comes to nutrition or more opinions than facts to go around?

Every day we hear new theories about diets, supplements, best foods, my role is to take

them mystery out of good nutrition and look at the science.

Welcome to the Nutrition Facts Podcast.

I'm your host and Dr. Michael Greger.

And I'm here to bring you an evidence-based approach to the best way to live a healthier

and longer life.

It's time for the Nutrition Facts Grab Bag.

We look at the latest science and whole variety of topics.

First up, we look at why some experiments show that duct tape is ineffective for treating

warms.

In 1978, a new approach for the treatment of warms was described complete with compelling

before and after pictures and what wasn't the application of adhesive tape.

This was put to the test head to head in a trial of duct tape versus cryotherapy to

resounding success.

Now though this was a randomized controlled study, it wasn't a double blind study.

My patients in the duct tape group were instructed to remove all tape prior to making a return

visit, so the nurses measuring the warms changes wouldn't be biased one way or the other.

But remember, look, cryotherapy can cause redness, skin discoloration, crusting, and blister.

So the nurses may have had an idea which kid was in which group, maybe that could have

biased them.

So, ideally, there would be a double blind randomized controlled trial of duct tape for the treatment
