I believe this is the link to the abstract:
http://www.onlinecjc.ca/article/S0828-282X(12)01034-3/fulltext

You can also get a PDF from that site.

I haven’t read the paper yet, but I wanted to share the resource so that everyone can get into it right away.

Reference to “high school science project” is slander.
Science projects in high school are generally worthwhile
and worked through carefully.

“days when they hadn’t eaten any breakfast.” is NO kind of control for a high-fat breakfast. Perhaps a breakfast of equivalent weight, or equivalent calories might be considered an appropriate control, but no breakfast is definitely NOT a control. After eating, blood vessels in the viscera relax (for more blood flow) and those in the periphery (such as the arm, DUH), constrict so that the blood flow is lowered and available to the G.I. tract. So of course blood flow to the arm was decreased. Was this a high-school science project?

There are no studies. There are no measurements. The Smithsonian article… IF YOU CAN BELIEVE THEY WOULD PUBLISH THIS TRIPE, SAYS”

“The students’ arterial health was calculated”. THEIR HEALT WAS CALCULATED!? Calculated!!!???

Is there anyone on the editorial staff with half a brain, a scientific degree… OR JUST OL’ COMMON SENSE????

THEIR HEALT WAS CALCULATED!? Give me a break!

Hi.
You know what would be REALLY SURPRISING. Uncovering the SCIENTIFIC LIES ON SATURATED FAT. This is slowly coming to light by several REAL SCIENTISTS WHO ARE NOT BOUND BY POLITICS AND LOBBYISTS. Please look into this, and please publish what you find, if you have any integrity at all. This article is old school, time to go NEW SCHOOL.

The article states, “Their VTI numbers were 15 to 20 percent lower than on other days when they hadn’t eaten any breakfast.” Therefore, all this proves to me is that eating anything lowers your VTI numbers. Perhaps they would like to suggest we stop eating?

I would be more interested in the results of this study if they compared VTI numbers after eating various foods for breakfast. Until they do that, I believe their results are meaningless.

Wait, where’s the control? Was there a group that ate a low-fat breakfast and didn’t show a change in blood flow? Is this just an effect of blood getting diverted to digestion, or of people moving differently when very full, or of large amounts of sodium?

NICE photo but I’ll bet its the wheat in the bread that is causing problems for America -not the Yummy stuff in between.
Its looking more like dwarf wheat, that the food industry has adopted as its number one “across the board” choice (for its cheap price)-is the problem specifically. Untested designer grains(high yield, drought & insect resistant) are great for cash flow, but feeding us a grain mutation unsuitable for long-term human health is raising its ugly head of consequences.

Dwarf Wheat -the secret triple whammy -Super Carbs, Super Gluten, super addictive (amylopectin A)- May well be the public warning you’ll be putting out there, once you shake loose of the hypnotic chant from the 80s… “All whole grains are all so good (for you)”

Get off the wheat pipe, and get on the stick. Folks need relevant, accurate and updated input, not recycled rhetoric from three decades ago.

Now go try it again.

Studies like these are so maddening. Calling a fast-food, super processed breakfast sandwich simply a “high-fat food”. There are several other macronutrients in that sandwich. The nature and source of the fat isn’t in question.

So yeah, what commenter dodny said.

“Their VTI numbers were 15 to 20 percent lower than on other days when they hadn’t eaten any breakfast.”…

This is a poorly written article. According to this sentence, the cause could be eating in general. I see no comparisons to any other alternatives such as a breakfast of oatmeal. There is are no references, and this does not appear to have been a double blind study. Bad science!! All of this makes this article unreliable at best.

This article is so flawed. First of all, it ASSUMES that “a higher VTI number indicates better blood vessel health.” Really? At any one time, all day long, even after meals? It only monitor VTI as a sole indicator of good health. Really? Our body is more complex than that. Were they monitor anything else? We have 5 senses, and many organs, and zillions of cells. Did anything good come out of eating such a meal? None? If not, why so many people eat them? Did they look at any other variables? If they didn’t, then they should NOT make a conclusion based on one single factor and one single indicator.

Not finding the actual study, I would like to have seen what the controls were. Did they have another group eating a low fat breakfast item, and test their VTI? We may already know something about general harmful effects of high fat diets, but the dramatic (sensational) element in this study is the proposal that a high fat breakfast uniquely produces such a sudden effect. But they weren’t actually measuring arterial plaque; just a blood vessel dynamic that otherwise is known to be affected by plaque or blood vessel wall changes. (did they also do duplex ultrasound or other diagnostic of blood vessels?)
I am prompted to wonder if eating ANY meal, low or high fat, isn’t normally a regular cause of VTI changes in a ~ 20 minute window. Something like a blood shunting dynamic from the onset of a digestion event, causing hemodynamic changes in the periphery…

There are a few problems with this. First, it is NOT very well established that a high fat diet increases your chances of those unsavory ailments you mention. Although the studies may show that high fat diets are associated with increases in such things, it’s ambiguous, at best, whether the high fat part of the diet actually cause any of those problems.

Second, it’s almost impossible to draw conclusions about the impact a high fat breakfast has on the body without controlling for carbs. It’s been known for years now that the body reacts differently when carbs are kept below certain levels. For example, it’s known that many of the risk factors for the ailments mentioned in this post decrease when carbs are removed from a person’s diet and replaced with fat.

Of all the links posted, I can’t find one for the actual study, so it’s difficult to know if they actually controlled for carb content. Unlikely if all that is mentioned in this post is breakfast sandwiches. If I had to bet, after not seeing the study, I’d give five to one odds that the conclusions drawn in this blog post and/or study, as they relate to fat content, are insupportable by the study.
