Summary

Dairy is often treated as a single food group, yet milk, yogurt, cheese, and butter can have very different effects on health. Some evidence links yogurt to favourable outcomes, while butter is known to raise LDL cholesterol. And then there's the paradox of cheese: high in saturated fat, but not consistently associated with higher heart disease risk.

These complexities raise the question of whether the "dairy matrix" (the combination of nutrients and food structure) explains why not all dairy acts the same.

In this episode, Prof. Jean-Philippe Drouin-Chartier, a nutrition researcher and registered dietitian, is on the show to examine what recent trials and large population studies tell us about dairy foods and cardiometabolic health. The discussion covers blood lipids, blood pressure, glucose metabolism, and how guidelines should interpret this evolving evidence.

Hello and welcome to Sigma Nutrition Radio. This is episode 575 of the podcast. My name is Danny Lennon.

0:07.8

You are very welcome to the show. Today we're going to be taking a look at some of the research

0:12.0

relating to dairy consumption and cardiominabolic disease risk. And to go through this, I'm going to

0:17.0

be talking with Professor Jean-Filippe Drouin Chartier, who is an assistant professor at the Faculty of Pharmacy at LaValle University in Canada, as well as being a registered dietitian.

0:27.7

In addition to his PhD from LaValle University, he went on to complete postdoc training at the Harvard School of Public Health.

0:35.0

He conducts multidisciplinary research that integrates clinical trials,

0:39.0

epidemiology, and metabolomics, all to try and understand how both diet, including what we'll

0:44.3

talk about with dairy consumption today, as well as medication can interplay to prevent and

0:49.3

manage cardiometabolic diseases, so things like type 2 diabetes, hypertension, cardiovascular disease.

0:54.9

So today we're going to be looking at a number of his publications relating to dairy consumption,

1:00.5

as well as the wider literature, to get a handle on how dairy may impact risk of different things

1:07.8

like hypertension or type 2 diabetes, what the evidence might say,

1:12.8

differences we might see between different types of dairy products, how we can think about

1:17.4

this area of research more broadly, and then come to some useful conclusions. So if you are

1:23.0

interested in getting a set of detailed study notes to accompany this episode. Remember, you can do so by

1:28.3

being a Sigma Nutrition Premium subscriber. All those details will be linked in the description

1:32.5

box where you're currently listening. In the description box, I'll also put a link to the studies

1:37.5

that we discuss throughout this particular episode if you do want to go and read the full text of those.

1:42.4

And in addition, those of you listening on the

1:44.6

premium feed of the podcast will get our key ideas round up after the interview finishes. So

1:51.5

that is it. I will get straight to this discussion between myself and Professor Jean-Philippe,

1:57.8
