According to the online site WebMD,
more controversy is coming. In my reading lately, fructose and
gluten-free are the latest to enter the controversy. We have seen
sodium and fat at the head of the line, but the latest two entries
are interesting. I feel that research agendas are driving all the
controversies and not pure scientific research.
As a person with diabetes,
high-fructose corn syrup is on the list of “do not eat items.”
Therefore, it is with more than a passing interest that I read these
articlse. I do have to wonder why there is no listing of the people
who are quoted in the WebMD article and who they work for. Yes, in the
WebMD article they are all associated with Canadian or US
universities, but are they truly independent from the grain industry?
I have in the past, not been too kind
to the corn industry and have had several nonproductive conversations
with people in the industry. They always spouted the mantra of
“sugar is sugar” and quoted industry experts that proclaimed
there was no difference. They have well rehearsed answers. This is most unsatisfying and leaves the
discussion without any conclusion.
Most studies are too small and thus not
very reliable. Quite possibly, they were done to obtain the results
of the agenda of the researchers. This is disturbing at best. Plus,
most studies or done using healthy people and not people with
diabetes.
By reading a blog by Tom Ross here, and
following his link, you may read about a study on fructose reported
in the Annals of Internal Medicine (page down to find the abstract).
Their review states that most trials had methodological limitations
and were of poor quality. They do conclude that fructose does seem
to cause weight gain when substituted on the same caloric level as
the carbohydrate replaced.
Therefore, with the caloric intake
being equal, fructose does not automatically mean weight gain. Now I
have to question whether most people can reduce the caloric intake
when they are unaware of the number of calories that have been added
to their soft drinks and other processed foods. This is where better
labeling requirements need to be placed on foods with added fructose,
regardless of the type of fructose. The control group did have
weight increase when the fructose calories were in addition to the
carbohydrate calories already present.
These studies do make some sense of the
fructose issue, but there are still many unanswered questions about
the effect of fructose on the body, especially the lipid levels
produced by fructose.
Now we have another study saying the
opposite of these studies. “These studies may provide important
insights into the cause of the prediabetic condition known as
"metabolic syndrome," which currently affects more than
one-quarter of adults in the United States.” Whether
this is true, or is just another agenda driven study remains to be
seen. Obviously there will be more studies.
