Very Interesting Research On Gluten, Inflammation, More!
0

9 posts in this topic

I was wandering around the Internet the other day, and ran into this site where a scientist is talking about gluten, inflammation, celiac, Hashimoto's, other autoimmune conditions, and I think it well worth taking a look.

The scientist is a Ph.D in Cellular and Molecular Biology, the title of his blog is Cooling Inflammation. The tagline on his title page says

"Cooling Inflammation: Inflammation is the foundation for cancer and degenerative/autoimmune diseases. Small changes in diet and exercise, e.g. omega-3 oils, vitamin D, low starch, plant antioxidants, and maintaining muscle mass, can dramatically alter predisposition to disease and aging, and minimize the negative impact of genetic risks. Based on my experience in biological research, I am trying to explain how the anti-inflammatory diet and lifestyle combat disease."

Thanks for the link! My hubby is type 2 diabetic and consumes a LOT of artificial sweeteners. He recently started using agave in his tea (because I quit buying diet soda)with the thinking that it doesn't spike his blood sugar so should be good? With elevated liver enzymes already going on in him I'm going to get rid of his agave and get stevia. There's no way I can get him to go without his sweets.

Compliments to the developers of this site, looks great and is a nice source (reliable) for info. The son of a friend has been suffering symptoms; mom's not sure it's celiac. I'll be suggesting she visit here. Thanks for being on the net.

Dr. Oz on Sweeteners: Sugar, Fructose, Insulin/Resistance, AGE, Fatty Liver

http://coolinginflam...r-fructose.html

I was shocked when Dr. Oz recommended a snack made with agave syrup. I had seen a previous program by America's representative of the medical industry in which he revealed the hazards of agave syrup as a new source of fructose. Now he just skipped over the use of this fructose syrup as a "natural" sweetener, even though it is even less healthy than high fructose corn syrup, HFCS. There seems to be a lot of deliberate confusion about sweeteners and since I am trained as a carbohydrate chemist, I will try to tell it as I see it.

General Information

Carbohydrates are not needed in your diet, since your liver can make all the blood sugar that you need from fats and protein. Most diabetics can benefit from a low carbohydrate diet.

Glucose, the blood sugar, is primarily responsible for turning on insulin production, so sweeteners (glucose, sucrose, HFCS, corn syrup) or dietary carbohydrates (starch, e.g. cereal, rice, pasta, potatoes, bananas) that are readily converted to glucose, cause blood insulin levels to rise.

Fructose in any form (HFCS, sucrose, agave syrup) contributes to liver damage. Fructose is the most chemically reactive sugar.

Artificial sweeteners, especially in soft drinks, do not contribute dietary calories, but they apparently increase insulin production and contribute to hunger, eating and obesity.

Insulin production removes glucose from the blood, i.e. lowers blood sugar, by increasing glucose transport into fat cells. If glucose is in your blood, but insulin is not present, e.g. type I diabetes, then you get thin. If glucose is in your blood and insulin is present, then you get fat. If you are fat and glucose is still high in the blood and insulin is present, then the fat cells will die unless they shut off the insulin response, i.e. insulin resistance. Lowering the amount of carbohydrates, sweeteners/starch, in your diet makes it easier to control blood sugar levels and avoid hunger.

Decreasing dietary carbohydrates means that calories have to be present in some other form and the answer is saturated fat. Most polyunsaturated fats, e.g. vegetable oils, except olive oil, are not healthy. The fats in meat, butter, eggs and coconut oil are the healthy choices supported by the biomedical literature, and along with vegetables, form the foundation of a healthy, anti-inflammatory diet.

Central Metabolism Started with Fructose not Glucose

All organisms convert sugars through a common series of enzymatic steps, called central metabolism, to a simple, three-carbon compound called pyruvate. Pyruvate can be used as a source of energy in mitochondria in the presence of oxygen or converted into alcohol or acids in various forms of fermentation. No matter what sugars are used, e.g. glucose, galactose, mannose, they are all converted in cells into derivatives of fructose. Thus, fructose is common to all organisms and can be considered to be the most primitive. So why is glucose usually considered to be the the start of central metabolism and why is dietary fructose dangerous?

Fructose is too Reactive to Transport

The first cells used fructose as the starting material to make the building block molecules of cells, e.g. carbs, proteins, fats, nucleic acids, and energy in the form of ATP. Multicellular organisms, such as animals and plants had to move sugars from cell to cell. It would be obvious to transport fructose, since all other molecules could be converted into fructose, but the problem is that fructose is too chemically reactive, i.e. it reacts with proteins to form AGE. It is for that reason that fructose is converted by cells into glucose, which is less than one tenth as chemically reactive. In plants, the reactive groups of glucose and fructose are bonded together to produce sucrose, table sugar, which is much less reactive and can be transported in plant vessels at very high concentrations.

High Blood Sugar is Bad, High Fructose is Worse (AGE-ing)

High levels of blood sugar, glucose, react with proteins to produce advanced glycation end products, AGE. Fructose in the blood produces these inflammatory compounds more than ten times faster. That is why fructose is a bad sweetener for diabetics. Eating fructose, e.g. agave syrup or sucrose, doesn't directly raise blood sugar/glucose levels, since it raises blood fructose levels, which is worse. Fructose Fattens Livers Fructose is rapidly absorbed in the intestines and transported to the liver. The blood vessels of the liver remove fructose from the blood and it is rapidly converted into fat. Fructose in sweeteners has now surpassed alcohol as the major source of liver disease. Sweeteners Fructose is ten times sweeter than glucose, and that is why cheap forms of glucose, such as corn syrup, are treated with enzymes to convert some of their glucose into fructose to produce high fructose corn syrup. Corn syrup is not as sweet as pure glucose, because the syrup contains a mixture of short chains of glucose of different lengths, and the chains decrease in sweetness with length. By changing some of the glucose into fructose, the HFCS can be made as sweet as table sugar, sucrose. Corn subsidies keep corn syrup cheap and make HFCS very profitable. Unfortunately, the HFCS contains fructose and therefore it has the liver toxicity and AGE-forming inflammation of fructose.

Agave Syrup is Fructose

Agave syrup is pure fructose produced by industrial processing of the fructose polysaccharides in agave extracts. I cannot understand why anyone would use this commercially processed fructose as a sweetener. It doesn't raise blood sugar, because it raises blood fructose levels instead, which is much, much worse.

Sugar Makes You Hungry

The human body can only use simple sugars, e.g. glucose, fructose, sucrose, or starch. Body enzymes convert sucrose into fructose + glucose, and starch into glucose. Other carbs, such as soluble fiber, are only digested by gut bacteria in the colon. The conversion of starches to glucose begins with enzymes in saliva in the mouth and is completed in the upper part of the digestive tract. Starch should be considered as a simple sugar, because it causes a rapid rise in blood sugar, just like glucose. It may actually be faster than table sugar. The rapid rise of blood sugar causes a rapid increase in blood insulin, which in turn rapidly removes sugar into fat cells. The rapid rise and fall of blood sugar provides the experience of hunger. That is why cereal, e.g. oat meal, in the morning produces intense hunger just a few hours later. Actually, oat meal is not quite as unhealthy as most cereals, because it also has some soluble fiber to feed gut flora. A protein and fat breakfast, e.g. bacon and eggs, does not produce rapid hunger, because it does not produce a large insulin rise and glucose fall.

Insulin Resistance is Better than Death by Glucose

As fat cells accumulate glucose as a result of blood sugar transported into the cells in response to insulin, more and more of the glucose is converted into fructose and on to pyruvate. The pyruvate accumulates in mitochondria and ATP production is saturated. This is potentially lethal for the cells, because the conversion of pyruvate into ATP is accomplished by removing high energy electrons as the pyruvate is converted to carbon dioxide. The high energy electrons accumulate in the inner membranes of the mitochondria and if they are not systematically converted to low energy electrons and dumped onto oxygen to produce water, reactive oxygen species, ROS are produced and the result is inflammatory oxidative stress. Antioxidants would be needed to protect from major cellular and organ damage. The cells protect themselves by responding to the accumulation of high energy electrons on the mitochondria by shutting down the response to insulin and blocking further intracellular glucose accumulation. This is insulin resistance.

Carbs: Never too Low

Dietary carbs, such as sugars and starches are not needed, because the liver can convert fat and protein into glucose. Thus, diabetics, who have a hard time balancing their dietary intake of carbs with the insulin that they inject, can simplify the process by routinely eating less carbs spread through many meals and triggering some glucose production by the liver. Craving for carbohydrates/sweets can be dramatically reduced simply by eating fewer carbs and avoiding insulin production that can lead to more dramatic swings of blood sugars and hunger. Using this strategy, I am hungry less than once a week.

Healthfulness of Sweeteners

--from Most Healthy....

Stevia - is a protein that is sweet, doesn't raise blood sugar, no insulin spike and no AGE

Glucose - raises blood sugar, spikes insulin and produces AGE

Xylitol - is a sugar alcohol that inhibits dental bacteria, doesn't raise blood sugar, no insulin spike or AGE

Corn Syrup - raises blood sugar, spikes insulin, produces AGE, low sweetness

Sucrose - raises blood sugar, spikes insulin and produces AGE, and liver damage

Honey - is half fructose and half glucose, raises blood sugar, spikes insulin, produces high AGE and may damage liver

Artificial Sweeteners, aspartame, sucralose, saccharin, etc. - don't raise blood sugar or produce AGE, but may have other risks, including hunger

HFCS - is high fructose corn syrup, raises blood sugar and spikes insulin, produces very high AGE and causes liver damage

Fructose - doesn't raise blood sugar or spike insulin, produces very high AGE and causes liver damage

Agave Nectar - is fructose, doesn't raise blood sugar or spike insulin, produces very high AGE and causes liver damage

And for another viewpoint that doesn't villianize carbs, there's Ray Peat's article found here:

http://raypeat.com/articles/articles/sugar-issues.shtml

It's a long article, but it has some very interesting information.

Another downside that I found about agave syrup is a seriously negative effect on fertility. It has compounds that work as contraceptives. Anyone who is pregnant or trying to conceive should stay far away from agave.

    • Anxiously waiting
      Thanks heaps. I will def be going private if the wait is too long. I have done a little research but i thought a gluten intolerance and coeliac was the same lol. My iron levels are just below average apparently but she said not bad enough for me to be this tired.
    • Celiac.com: Traveling While Gluten-Free? What To Consider From Someone with Celiac Disease
      There are a few definite truths about living gluten-free: You miss bagels every day. Curious friends regularly badger you with questions like “is ... View the full article
    • How effective is HD skin biopsy after being gluten free for a year
      DH is celiac disease that appears on the skin (gluten triggered).  It does not appear when you are consuming dairy, which sounds like a separate issue for you.   A DH biopsy requires active lesions (new/fresh) from consuming gluten.  So, if you want to be tested via a skin biopsy you must go back on gluten.  Finding a dermatologist who knows exactly how to biopsy for DH is often difficult.  Be sure your Derm is knowledable and has biopsied for DH before. Why no endoscopy for now?  I bet your GI  knows that your insurance will deny the endoscopy.  After all, you tested negative to the blood panel.  Your GI should not even ordered the blood panel knowing that you had been gluten free for months.  You have to be consuming gluten daily for 8 to 12 weeks for the blood test to be accurate.   Did you ever test positive?  Why did your primary diagnose you?  Having the gene just means you can develop celiac disease.  Some 30% of the population carries the genes.  The gene test should only be used to help rule out celiac disease.  
    • How effective is HD skin biopsy after being gluten free for a year
      No one can say exactly how long you might be able to get a positive dh biopsy after having been gluten free as long as you have been. The Chicago Celiac Disease Center says this: http://www.cureceliacdisease.org/faq/im-scheduled-to-have-a-skin-biopsy-to-screen-for-celiac-disease-should-i-maintain-a-gluten-containing-diet-similar-to-those-who-are-being-screened-via-blood-or-intestinal-biopsy/ http://www.cureceliacdisease.org/faq/what-is-a-gluten-challenge/ You said you had a flare of the plaque psoriasis -- that is NOT dh so why do you think the dh biopsy will show positive? Testing positive for the celiac genes does not mean you have celiac disease. 30+% of the population have the celiac genes but only very, very small fraction of those people do or will present with celiac disease. The gene tests are only used to rule OUT celiac NOT to diagnose it. Frankly, I can understand why your GI does not put any stock in your Primary doc's thinking you have celiac disease. A positive celiac gene and the boils in your armpits which the GI never saw and were never biopsied for dh but they resolved on a gluten free diet and so did your plaque psoriasis. That's all the GI has to go on. I don't know why you are pushing an endoscopy. If you've been eating strictly gluten free then an endoscopic biopsy for celiac will be negative.  Your PCP should have done a celiac blood panel on you back when you were still eating gluten rather than dx you based on the celiac gene you tested positive for.
    • How effective is HD skin biopsy after being gluten free for a year
      I've been gluten free for a year now and my gastro wants to wait for the endocopy until I'm eligible for the colonoscopy when I turn 50 later this year. I don't think she believes I have celiac, even though I tested positive for one of the genes associated with celiac and my primary has diagnosed me as having celiac. The gluten sensitivity blood tests came back negative, of course, since I was gluten free for 9 months at that time. Why is she waiting? At any rate, My digestive system has improved greatly, but when I reintroduced non fat Greek yogurt in my diet, the plaques psoriasis returned on my elbows. My primary believes it is dermatitis herpetiformis (as well as I, since before going gluten free, I used to get boils in my armpits) and I'm scheduled for a skin biopsy in 3 weeks. However, I eliminated dairy from my diet 4 weeks ago and the plaques psoriasis is healing like it did when I eliminated gluten from my diet a year ago. If the scar is reduced to eczema, does that mean there still are IGA deposits in my skin? I don't want to resume dairy since I experienced a cross reaction to the casein in cheese and found lactose was on that same list. So my question is, how long do the granular IGA deposits remain in the skin in order to have a valid skin biopsy test performed for dermatitis herpetiformis? Since it takes 1-2 years for dermatitis herpetiformis to heal on a gluten free diet and I just had a recent flare up, can I continue on my dairy free diet or should I resume eating non fat Greek yogurt for the next 3 weeks just for this skin biopsy?

      Hi There, I don't know if there is a place for videos in the forum. I just watched "The Truth About Gluten" I think it is a good video. I would like to share it somewhere but don't know where it should go. Any help would be greatly appreciated.
      Here is the link if you have never watched it.
