Hey folks, Ben Greenfield here and in today's feature topic, I've got Udo Erasmus coming on. This is a guy who knows more about fat than just about anybody on the planet.

He's written the book, fats that heal, fats that kill, so I would highly recommend that if you want to understand this whole fat debate a little bit more that you listen into that interview.

We have a Q&A and a very important announcement about the Q&A that you shouldn't miss if you're a regular listener to the podcast or somebody who wants to ask questions for the podcast.

And of course, just a few special announcements before we rock and roll. So let's jump right in to this week's content from Ben Greenfield Fitness.com.

Special announcements.

Folks, I am no longer taking questions for the Ben Greenfield Fitness.com podcast via email. I've instead set up a form on the website and that form can be found on the show notes for any podcast episode.

So whenever you have a question, just go to Ben Greenfield Fitness.com, click on the show notes. So for example, you would click on the show notes for this episode. This is episode number 127.

And down by the Q&A, there is a little form that you can fill out. So that will allow you to effectively ask me a question and have that question get directed straight into a Q&A folder that I am able to view.

The reason I'm doing that is because I was literally getting hundreds of email questions each week and it was getting very difficult for me to navigate through filter those questions and effectively be able to take care of you.

So now we are using that form. The only exception to that rule is that if you have the free Ben Greenfield Fitness iPhone app, you can continue to ask your questions through that iPhone app.

And then of course, you can also ask your questions toll free 877 209 943 9 or you can Skype me at username Pacific fit.

The other announcement that I have for you is that I will be speaking in Sacramento, California on January 22nd at a health event.

That's going to be a Saturday evening and I will put a link in the show no so this episode episode number 127 if you're interested in attending that event in meeting me or in listening to a speech that I'm going to be giving on how to make your health more prosperous in 2011.

So let's go ahead and move on to this week's listener Q&A.

So the first question for this week comes through from listener Patrick who says, is there any validity to the claim that taking in natural shovers is somehow less damaging to your body than processed high fructose corn syrup or refined shovers.
