Mary Claire HaverHOST
I looked at a cross-section of, of observational studies.
Mary Claire HaverHOST
They went back and looked at the NHANES data, the WHI data.
Mary Claire HaverHOST
They followed these women in these, these cohorts for decades, right? And they looked at nutritional studies, thank God, that, you know, they tracked their nutrition and then they tracked frailty and their frailty scores.
Mary Claire HaverHOST
And there was a correlative response of how much protein women were eating and their risk of frailty.
Jeffry GerberGUEST
But what you can do is apply it to populations.
Jeffry GerberGUEST
And so in this case, we're going to apply it to a recent NHANES study that came out last year that predicted that there's a staggering 52% of the US population that have diabetes and prediabetes.
Jeffry GerberGUEST
And what was really good about the study is they took the 2011 and 2012 cohort.
Jeffry GerberGUEST
And it was almost 3,000 patients that represented the US population.
Ken BerryHOST
This paper contains no new research whatsoever.
Ken BerryHOST
It uses the data from the NHANES dataset, which was collected between the years 1999 and 2014.
Ken BerryHOST
This study had nothing to do with intermittent fasting.
Ken BerryHOST
This study was entitled Skipping Meals.
Ken BerryHOST
And I'm going to explain why in just a few minutes.
Ken BerryHOST
So this study was based on NHANES data, which was collected between 2003 up to 2014, 2018, depending.
Ken BerryHOST
So right off the bat, if you were alive and an adult in 2003, you remember nobody was talking about intermittent fasting then.
Ken BerryHOST
It was not a thing at all.
Ken BerryHOST
What they did was they dug back into the NHANES data set back to a time period where Jason Fung was not a household word.
Ken BerryHOST
Nobody was talking about doing longer fasts or intermittent fasting.
Ken BerryHOST
Now, it's absolutely true that humans, as a species, have been practicing fasting, long fasts, for thousands and thousands of years.
Ken BerryHOST
So you didn't just lay down and die.
Jack CushHOST
So, again, encouraging data on combination therapy.
Jack CushHOST
An NHANES study looked at the... utility of measuring waist size you know i think this is a problem i'm going to ask this on my tuesday night rheumatology to my diabetes and rheumatology experts are you actually measuring the waist size of your patients i have found that to be a really most patients don't even want to get on the scale right how many of them want to have their waist size measured You know, you know, they've been saying, no, I, Jerry Seinfeld, no, I have 36, you know, um, genes, 36 waste genes and they're not, you know, um, so anyway, in this study of 5,500 CKD patients.
Jack CushHOST
Waist index was associated with a higher risk of all-cause mortality and cardiovascular death, 17% to 24% higher.
Jack CushHOST
And these were mediated by inflammation as measured by the neutrophil to lymphocyte ratio, a good measure of inflammation.
Jason FungHOST
And luckily for us, there is.
Jason FungHOST
The NHANES-1 data was, so the NHANES was a United States data, and they basically take a huge population-based survey of the United States, looked at all different kinds of things, and one of the things they looked at here, and it published in The Lancet in 1998, was salt.
Jason FungHOST
So here they break them into quartiles.
Jason FungHOST
So this is what they normally do is they take people and they divide them on how much salt they take.
Jason FungHOST
Okay? That's, again, contrary to what we would believe for the most part.
Jason FungHOST
And that holds for total mortality and cardiovascular mortality.
Jason FungHOST
You can look at the NHANES-2 data, which is a little bit more recent, published in 2006, and you can look at the same thing.
Jason FungHOST
So this is 13.7-year follow-up.
Jason FungHOST
You give them excess amounts of fructose, and immediately you see this rise in triglycerides.
Jason FungHOST
If you look at the amount of sugar, so this is NHANES data, which is about 6,000 adults, which they did a general survey, and you can see the more sugar that you eat, so this is the percentage of energy from added sugar, the higher your triglycerides.
Jason FungHOST
The more sugar you take, the higher your triglycerides.
Jason FungHOST
The HDL, which is the good cholesterol, again, a good cholesterol, the higher it is, the better you are.
Jason FungHOST
If you look at where they're just taking healthy people and giving them fructose, again, your triglycerides goes up, your bad cholesterol goes up, and the good cholesterol doesn't do anything.
Jason FungHOST
Some of these other further measures are also made worse, which is the small, dense lipoproteins.
Jason FungHOST
You can also see the same effect with blood pressure, that is, if you take, this is the amount of, this is again NHANES data, which is a kind of general survey of the United States, and what you can see is that if you take the people who took high blood pressure, this is high blood pressure, there's a clear correlation between the amount of sugars that you take and blood pressure.
Jason FungHOST
So this is the odds ratio for high versus low fructose.
Jason FungHOST
We still want to blame the victim, blame these individuals for following the very, very bad advice.
Jason FungHOST
And this is sort of what happened with the NHANES data.
Jason FungHOST
You can see obesity just kind of going up and up and up.
Jason FungHOST
And this is the real problem, right? The calories in, calories out sort of theorem of what we are trying to do.
Brad DieterHOST
And this, you know, this idea of being physically active and physically fit having a preventive effect also ties into people who already have established chronic disease.
Brad DieterHOST
And so there was a separate paper that came out of the NHANES, so the National Health and Nutrition Examination Survey or Study, I think is what NHANES stands for.
Brad DieterHOST
But they found that even people who had a chronic disease, specifically type 2 diabetes, those in the highest fitness kind of third, the top third, they had an all-cause mortality risk as low or lower than people who did not have diabetes but were at a lower fitness level.
Brad DieterHOST
So having high kind of physical fitness, especially when we talk about like cardiovascular fitness, that can offset a meaningful share of kind of chronic disease-related mortality risk, right? And so we have to start thinking about like on the preventative health side, physical fitness, having your body be fully prepared and at its peak or close to its peak or functioning at a very high level compared to being highly sedentary and not having a robust cardiovascular system, a robust musculoskeletal system.

Veterans between 20 and 39 do, and a new study is pushing the VA to reconsider whether it should be testing for that difference at all.
speaker_0HOST
Researchers at Brown University analyzed eight cycles of the National Health and Nutrition Examination Survey spanning 2003 through 2018, comparing serum PFAS concentrations across 1,552 veterans and 11,415 non-veterans, a sample that represents roughly 22.8 million U.S. adults with prior military service once weighted.
speaker_0HOST
The findings, published in Environmental Health Perspectives, found no overall difference between veterans and civilians, consistent with other recent PFAS biomonitoring work showing that exposure gaps often only appear once researchers narrow in on a specific subgroup.
speaker_0HOST
Narrowed to veterans ages 20 to 39, the picture changed.
