Adding peanuts to a meal benefits vascular health

Summary:
A study of peanut consumption showed that including them as a part of a high fat meal improved the post-meal triglyceride response and preserved endothelial function. Vascular dysfunction plays a major role in the development of atherosclerosis and the formation of coronary plaques and lesions that lead to coronary artery disease.

The purpose of this research was to evaluate vascular function after a high fat meal challenge. Fifteen overweight males were randomized to either a peanut meal containing 3 oz. of ground peanuts (as a shake) or a control meal (a shake without peanuts) that were matched for energy and macronutrients.
The lipid profile, glucose and insulin were measured five times after each meal. Flow-mediated dilatation (FMD) was measured to assess vascular function. This non-invasive method required a cuff at the forearm to restrain blood flow, which was then released to assess dilation of the brachial artery. The control meal decreased FMD by 1.2 percent compared to baseline. In contrast, there was no decrease in FMD after the peanut meal. These results demonstrate that the peanut meal maintained normal vascular function whereas the high fat-matched control meal impaired vascular function acutely.
Vascular dysfunction plays a major role in the development of atherosclerosis and the formation of coronary plaques and lesions that lead to coronary artery disease. Typically after a high fat meal, vascular function is reduced, albeit temporarily, until the fat that is in the blood (from the meal) is cleared. Strategies that can blunt this response to both dietary fat and its effect on vascular dysfunction may decrease the risk of coronary disease. Our finding demonstrated that that peanut consumption was shown to be atheroprotective as a part of high fat meal.

So if you are eating a high fat meal, SAD, then nuts are protective it seems to be saying.

I wish the article had provided a description of the ingredients/macronutrient content of the control shake. I'm curious what constitutes a "high fat" meal.

In other words, the researchers discovered that if you are chowing down on a bacon cheeseburger, fries and a milkshake that adding 480 extra calories worth of peanuts (3 ounces) to every fatty meal will improve FMD somewhat. And if you are eating two or three fatty meals per day as most Americans are then adding more than 1400 extra calories per day in peanuts is going to solve the heart disease problem. Wow. Science is great. Totally believable.

Well didi, we could start a charity handing out peanuts to fat people.

seriously though, nuts are different or unique and I want to know what nuts are doing to our metabolism etc.

[vgpedlr]

Doesn't really apply to people here. Not sure how anybody else can use this info. What a weird study.

[soul food]

Well thanks vegpedlr, I think the all nuts are evil, ban them, don't talk about them idea provokes me. Because it seems like blind prejudice. Yeah, I'm exaggerating but the reaction seems exaggerated as well. So thanks for letting me see that.

No I don't work for the nut board, or eat a lot of nuts , or sell nuts, but you may consider me nuts or weird.

A plant food is healthy? Shocking. LOL. Good to see though.

They weren't even nuts to begin with since we're talking about legumes instead:

http://www.peanut-institute.org/peanut-facts/

Peanuts, along with beans and peas, belong to the single plant family, Leguminosae.

We can't fight fire with fire (chestnuts are still nuts but the calories from fat are low) and nuts won't do us a favor here. Isn't it more about legumes to the rescue?

I would believe the peanut study if it was paid for by the Snoopy Institute.

Maybe I'm just gullible, but I tended to trust Linus more. Maybe it's the blanket.

colonyofcells, good work!

Love your line about the Snoopy Institute! I'll have to re-use that one.

Sometimes life really is stranger than fiction -- who the heck studies already-unhealthy diets, searching for new ways to mitigate a crappy diet by a few percent? (The peanut institute does, apparently.)

I'll bet the Elmer's Glue institute will replicate the study using their product, showing that common elementary school paste *also* will improve your numbers, if added to an otherwise-unhealthy meal consisting of nothing but Cheetos and Crisco. Oy vey!

[dteresa]

The problem isn't with nuts or even a fatty legume, but adding them to a bad, if not dangerous, diet and speculating that those extra calories would somehow render it healthful. Except for those with artery problems for which wfpb no fat is your best bet, at least according to Esselstyn, nuts or peanuts in amounts that wouldn't cause unwanted weight gain are an acceptable whole food.

That's not how I read it. It's not about adding additional fat to an already fatty meal. The meals were matched for calories and macronutrients. One fatty meal contained peanuts. The other didn't, but it had the same amount of fat.

"Peanuts are nutrient dense and energy dense, so Liu noted the importance of being aware of their calorie content when incorporating them in the diet. Thus, peanuts must replace other food sources of calories when included in the diet. For example, peanuts can be substituted for high fat, nutrient-poor foods in the diet that contain solid fats."

I just can't see things in this simple black and white kind of way. One study I read on bipolar people was that they had no middle ground just black and white in their descriptions. No fifty shades of grey or purple From herbal medicine I know that the description of the qualities of plants is huge, not in the simple category of it's a fat, a protein, a carb etc. And from science we know that these plants have many chemical properties and a huge array of complicated chemical interactions. So a nut or legume is not just a fat or protein to me.
The more I read and study up on this stuff the more complicated and complex it gets.

The "instant summary" on the latest study (thanks T.A.)
1. Vitamin E is necessary to transport the brain-essential fatty acid omega-3 DHA across the blood-brain barrier.
2. With sufficient Vitamin E, the concentration of DHA is 70% higher in the brain than with a deficient Vitamin E (see second figure C below).
3. "Human brains are very enriched in DHA but they can't make it, they get it from the liver," explains Dr. Traber. "The particular molecules that help carry it there are these lyso PLs, and the amount of those compounds is being greatly reduced when vitamin E intake is insufficient. This sets the stage for cellular membrane damage and neuronal death."
4. The best sources of the vitamin E are nuts and seeds such as sunflower seeds, almonds and hazelnuts. Although green leafy vegetables such as spinach and Swiss chard contain vitamin E, you have to consume about 2.5 cups of COOKED greens (that takes a lot of raw greens) to be equivalent to the amount of vitamin E in an ounce of almonds or sunflower seeds.
