Study Details Link Between Obesity, Carbs and Esophageal Cancer

As Obesity and Carb-intake Rates Have Increased, So Has Specific Cancer

Cleveland, Ohio – February 25, 2008 – Cases of esophageal cancer
(adenocarcinoma) in the U.S. have risen in recent decades from 300,000
cases in 1973 to 2.1 million in 2001 at age-adjusted rates. A new study
published in The American Journal of Gastroenterology shows that these
rates in the U.S. closely mirrored trends of increased carbohydrate
intake and obesity from 1973-2001.

The study illustrates what may be a public heath concern as the
composition of U.S. diets changes and total carbohydrate and refined
carbohydrate intakes increase. Obesity is a risk factor for many types
of cancer, and a diet that includes a high percentage of calories from
refined carbohydrates is a common contributor to obesity. Carbohydrates
were also unique in that no other studied nutrients were found to
correlate with esophageal cancer rates.

The causes of esophageal cancer remain largely unknown. Despite recent
advances in treatment, esophageal cancer has a poor prognosis. The
five-year rate of survival for esophageal cancer remains below 20
percent and is the eighth-leading cause of cancer related death in
American men.

“If we can reverse the trends in refined carbohydrate intake and obesity
in the U.S., we may be able to reduce the incidence of esophageal
cancer,” says Dr. Li Li, senior author of the study.

OBJECTIVES: The incidence of esophageal adenocarcinoma is on the
rise in the United States. In this ecological study using the
Surveillance, Epidemiology, and End Results (SEER) program (1973–2001)
and national food consumption data (1909–1997), we evaluated the
correlation between secular trends of dietary macronutrient intakes and
esophageal cancer rates.

METHODS: Linear regressions were performed to assess the
correlation between age-adjusted incidence rates of esophageal cancers
and nutrients.

RESULTS: The increase in esophageal adenocarcinoma was found to be
strongly correlated with the rise in carbohydrate intake (P 0.0001).
The decline in squamous cell carcinoma rates was negatively correlated
with carbohydrate intake in the univariate model (P 0.0001), but this
correlation disappeared when adjusted for other nutrients. Correlations
of esophageal adenocarcinoma to percentage of calories from corn syrup,
representing refined carbohydrates, were statistically significant in
the univariate model (P 0.0001), but decreased in significance in the
multivariate model (P = 0.0118). We also found a significant correlation
between obesity and esophageal adenocarcinoma (P 0.0001) during the
same time period.

CONCLUSION: Our ecological evaluation suggests that high
carbohydrate intake and obesity can account for at least some of the
rise in esophageal adenocarcinoma. Within-population studies are needed
to clarify these trends.

Hrm. Let's see if we can come up with a causative story. Just there
is correlation doesn't mean there ISN'T causation.

When I eat too many carbs, I, like many people, get vary degrees
of acid reflux. We might prove this one by looking at sales of
antacids and acid blockers against carb consumption, but from
my own experience (and the related clinical experience of Dr.
Atkins and the Eadeses), we're pretty sure about this. Carbs
cause acid reflux.

Stomach acid where it doesn't belong cannot be a good thing.
It hurts. But could it be doing damage, effectively diverting the
immune system from fighting newlyn tumors?

I'm not disagreeing about the headline probably being over
stated, but at the same time, it's pretty easy to see how it
might work.

So, you elect to add an unsubstantiated hypothesis for "clarification"
purposes.

Did you read the actual abstract as published by the study authors?

Or did you manage to just read the PR Press Release issued by the
publishers nearly 60 days after the actual publication?

I enjoy your "mastermind" at work.

Did you ever apologize to the other poster about the McDonald's dish
that you insisted wasn't there anymore?

I thought so.

I doubt at all that it's overstated.

I had chronic heartburn and severe acid reflux for most of my adult
life. I ate Rolaids like candy, then took Zantac once or twice a day
when it came out. I still had reflux, and would often wake up in the
night gagging on my own vomit, Within days after I started my low
carb way of eating, the heartburn disappeared. Within a few weeks,
the acid reflux had completely gone away. It's been probably two years
now since I had heartburn, and that was only when I went off my LC WOE
for a day or ate something carby that I shouldn't have. And there is
not question that acid reflux is the main cause of esophageal cancer.
No, I don't think the headline is overstated at all! I'm ore
surprised that someone hasn't pointed this out sooner.

"Unsubstantiated?" You're idiotic. You're talking stupidly about
something of which you apparently have no knowledge at all -- without
even doing basic research to verify your dumb statements.

Um, it's *you* who are talking out your substantial butt.
Chronic acid reflux has long been known to be a major cause of
esophageal cancer, and excess carbs cause acid reflux.

I had a similar experience which was cured (or controlled) by LC. That
reflux will definitely mess you up.

Yep, my reflux gone within days of doing Atkins induction level, several
years ago.

Different methodology at work, Jim. I forgot to add the usual thank
you
for the study. I always find them interesting. But, back to the matter
at hand. You like to look at the studies. I like to try and understand
the world. Understanding means putting forth hypotheses. They all
start unsubstantiated. Then they get tested and disproved. My
"unsubstantiated hypothesis" would be a useful avenue for further
study by these folks. So, they found a correlation. Next, look for
causation. Maybe you need to brush up on your scientific method
and your study design.

Did you read the actual abstract as published by the study authors?

I read what you posted.

I'm glad you do.
Did you ever apologize to the other poster about the McDonald's dish
that you insisted wasn't there anymore?

WTF are you talking about? Link please.

I thought so.

And you are always right, so never have to apologize. To avoid
further confusion, you should probably change your posting name to
"Perfect Jim." For the love of God.

PS- Keep the studies coming. The interpretation too. I like you. No
sarcasm.

I'm going to add to that. Reading Marengo on it is like my story, if
he were
younger and less far along the path. Sub Tums with whatever Acid
Blocker
they come with in the big bottle, and that was my candy. On top of the
other
candy.

No need for the link. I figured out what you were talking about. It is
me
who deserves your apology. The OP and I were talking about a company
that was once owned by McDonalds.

(requires flash)

You mistakenly thought we were talking about a menu item. Go back
to that thread, as the full explanation is there.

I thought so.

When YOU apologize to ME for:
1- The other thread where you have wronged me through your own
misunderstanding
and
2- This thread, where Marengo has countered your vicious attack
on me with more studies demonstrating the logic chain between
obesity, carbs, reflux, and cancer (which I had actually picked up
from Mike Eades Blog I dunno when, so didn't have the studies,
just the understanding).

At that point, all is square. Till then, you're in the wrong.
Sorry.
