“NBC’s
‘Today Show’ had a story about dietary cholesterol,” my wife said at breakfast
yesterday. Later we both heard a similar story on PBS’s “All Things Considered”
as we drove to our separate engagements. So, today I did a Google News search
on “dietary cholesterol” (the cholesterol in food, like eggs and shrimp, that
we eat). The first story that came up was from Fox News. It wasn’t very good.
The author puffed it up with off-message “contributions” from the AP and
Reuters.
Still, the
essence was that Marian Neuhouser, chair of the relevant subcommittee of the
2015 Dietary Guidelines Advisory Committee, announced a decision to the full DGAC
committee at its final meeting in December 2014. She said it is their recommendation
that dietary cholesterol no longer be ‘considered a nutrient of concern for
overconsumption,’ according to the Fox
News Report. A 6hr. 57min. indexed video of the full meeting, #7 (December
15), is online and can be seen here.
The final
report, “2015 Dietary Guidelines for Americans,” will be published by the
USDA/HHS later this year. “While those agencies could ignore the committee’s
recommendations, major deviations are not common,” The
Washington Post said.
“Five years
ago, I don’t think the Dietary Guidelines diverged from the committee’s
report,” Naomi K. Fukagawa, the 2010 vice chair, told The Washington Post. Fukagawa says she supports the change on
cholesterol. “Walter Willett, chair of the nutrition department at the Harvard
School of Public Health, also called the turnaround a ‘reasonable move,’” The Post reported. “There’s been a shift
of thinking,” he said. (“…a shift of thinking”? Incredible that he said that!)
Well, la-di-da,
the Titanic IS really changing course. (See: The Nutrition Debate #12: “Turning the
Titanic,” also #162, #189, #202, and #292). And this is MAJOR,
except that, with this report, saturated fat is left behind; it is
still one of the bad guys. But it’s good news for people who long for shrimp. I
actually know a few, including medical doctors, who have passed up shrimp being
passed as h’ordeuvres at a cocktail party, and others who eat egg whites
instead of whole eggs for breakfast. (See: The Nutrition Debate #176, “Eggs,
Cholesterol and Choline,” #211, “Eggs and
Satiety,” and #225, #228 and #265.
The danger,
of course, with the Titanic changing course, is whether it is turning to port or to starboard. If it turns to
starboard, it will run into a sea of ice flows and eventually solid sea ice.
Think eroded endothelial layers, advanced glycation end products (AGEs), and
clogged arteries from the rancid and oxidized LDLs (oxLDL) in overused and
overheated vegetable and seed oils. (See: The Nutrition Debate #21, “The Dangers
of Polyunsaturated Fats,” also #20, #22, #23, #24, and #49.)
That’s the
outcome that can be expected 1) from the 2013 AHA/ACC
recommendation that the target for total dietary fat consumption
be omitted
to allow fat to replace the formerly much too high Dietary Guidelines
recommendation for carbohydrates, both
simple sugars and highly processed carbs; and 2) that saturated fat consumption
be further
reduced from the previous 7% - 10% of total calories to 5% - 6%. With
this 1-2 punch the resultant recommendation will be that we consume more Mono
and Polyunsaturated fats. But, while monounsaturated fats are good, most PUFAs
are BAD.
That’s
exactly where the Titanic is headed, with the blessing of Robert Eckel, current
co-chair of the ACC/AHA guidelines committee and past president of the American
Heart Association. While he conceded that there is “insufficient evidence” to
make a recommendation to support dietary restrictions of cholesterol, he said
“a three-to four-egg omelet isn’t something I’d ever recommend to a patient at
risk for cardiovascular disease.” Some myths die hard.
The Post
story recalls the origins of the cholesterol myth. A Russian scientist at the
Czar’s Medical Institute in St. Petersburg fed cholesterol to rabbits for four
to eight weeks in 1913 and saw that the cholesterol harmed them. Then in the
1960s an American graduate student, Lawrence Rudel, noted that when the Russian
fed cholesterol to white rats, it had no effect. Later, Ancel Keys acknowledged
the difference between obligate herbivores (rabbits) and mammals (rats and
humans). In 1997, Ancel Keys, father of the diet/heart hypothesis (saturated
fat + cholesterol → heart disease), infamously said:
“There’s no connection whatsoever
between the cholesterol in food and cholesterol in the blood. And we’ve known
that all along. Cholesterol in the diet doesn’t matter at all unless you happen
to be a chicken or a rabbit.”
Then
there’s this: Updated findings of the famous Framingham Study, published in Archives of Internal Medicine (2009):
“In Framingham, Massachusetts, the more saturated fat
one ate, the more cholesterol one ate, the more calories one ate, the lower
people’s serum cholesterol. . . we found that the people who ate the most
cholesterol, ate the most saturated fat, ate the most calories weighed the
least and were the most physically active.” Quote from Dr. William Castelli, Director.
