Summary

Iron is involved in a whole range of biological processes and a consistent supply of iron is crucial for cellular turnover. But despite iron being an essential mineral for human function, it is highly toxic to cells and tissues if present at high levels. Therefore an intricate and tight regulation of iron is necessary.

If iron status gets too low, iron-deficiency anaemia can result. In such situations there is a shortfall in hemoglobin production, which leads to a range of issues in the body.

So how is iron status measured? Which biomarkers are most useful? Where can errors in diagnosis occur? What problems arise with iron deficiency? And what problems occur with iron overload?

In this episode, these questions (and more) are put to Dr. Austin Baraki, a practicing Internal Medicine physician and Assistant Professor of Medicine at William Beaumont Army Medical Center in Texas.

This episode is the first in a three-part series on iron.

0:00.0	Hello and welcome to Sigma Nutrition Radio. This is episode 465 of the podcast. My name is Danny Lennon and you are very
0:24.4	welcome to the podcast if this is your first time listening or you're very welcome back to the
0:28.3	podcast if you are indeed a regular listener. And today we're going to be talking all about
0:34.2	iron status, iron deficiency, iron overload and both the diagnosing and treating of those,
0:40.7	and all from a kind of clinical perspective. And this is the first episode in a three-part
0:45.9	series on iron that we're going to be covering on the podcast over the next couple of weeks. So today
0:51.4	I'm going to be chatting with Dr. Austin Baraki, who is a practicing
0:54.8	internal medicine physician and assistant professor of medicine at William Beaumont Army Medical
1:00.2	Center in Texas. And we're going to cover all the clinical and diagnosis side and talking about
1:06.4	things like iron homeostasis, what are the issues around iron deficiency, what problems that cause,
1:11.8	and then how we go about treating those things. And then in subsequent episodes, we're going to be
1:16.5	looking at the overall dietary aspects of iron intake from both diet and supplementation.
1:24.2	We're going to be talking to Professor Paul Sharp all about that. And then in the
1:29.0	final episode of the series, we're going to be focusing in on iron status in athletes and how that
1:34.5	impacts things relevant to athletes and performance and so on and some of the specific nature of that.
1:40.1	So hopefully having these three episodes in sequence will build your knowledge and allow you to hear things a couple of times to really emphasize them.
1:50.0	Also, each one should build on the next, although the idea is that each could be listened to individually and you'd still be able to understand that conversation.
1:58.0	But I think having them in a sequence should allow you to
2:01.5	take the most from it. So I hope you find this useful. So like I said today, we're going to be
2:06.5	looking at things like how is iron status measured, which biomarkers are most useful, where could
2:11.3	errors in our diagnosis occur, what problems arise with iron deficiency, what problems
2:16.4	that occur with iron overload, and a lot of
	...
