Red meat triggers toxic immune reaction which causes cancer, scientists find

Scientists at the University of California discovered that the human body views red meat as a foreign invader and launches an immune response

Red meat has been linked to cancer for decades, with research suggesting that eating large amounts of pork, beef or lamb raises the risk of deadly tumours.

But for the first time scientists think they know what is causing the effect. The body, it seems, views red meat as a foreign invader and sparks a toxic immune response.

Researchers have always been puzzled about how other mammals could eat a diet high in red meat without any adverse health consequences.

Now they have discovered that pork, beef and lamb contains a sugar which is naturally produced by other carnivores but not humans.

It means that when humans eat red meat, the body triggers an immune response to the foreign sugar, producing antibodies which spark inflammation, and eventually cancer.

In other carnivores the immune system does not kick in, because the sugar – called Neu5Gc – is already in the body.

Scientists at the University of California proved that mice which were genetically engineered so they did not produce Neu5Gc naturally developed tumours when they were fed the sugar.

"This is the first time we have directly shown that mimicking the exact situation in humans increases spontaneous cancers in mice,” said Dr Ajit Varki, Professor of Medicine and Cellular and Molecular Medicine at the University of California.

"The final proof in humans will be much harder to come by.

"This work may also help explain potential connections of red meat consumption to other diseases exacerbated by chronic inflammation, such as atherosclerosis and type 2 diabetes.


A study published by Harvard University in June suggested that a diet high in red meat raised the risk of breast cancer for women by 22 per cent.

In 2005 a study found those who regularly ate 5.6oz (160g) of red meat a day had one third higher risk of bowel cancer.

The average person in the UK has 2.5oz (70g) meat a day 3oz (88g) among men, 2oz (52g) among women) but 33 per cent have more than 3.5oz (100g) a day.

Previous research has suggested that a pigment in red meat may also damage the DNA of cells lining the digestive system.

CARBS LINKED TO LUNG CANCER!

http://www.ncbi.nlm.nih.gov/pubmedhe...-study-finds-/

"White bread, bagels and rice 'increase the risk of lung cancer by 49%','' the Mail Online reports after a US study found a link between lung cancer and eating a diet with a high glycaemic index (GI), a measure of carbohydrate content.

The study included more than 4,000 white people from Texas, both people newly diagnosed with lung cancer and healthy controls.

The researchers assessed their diet to look at whether there was any link between their diagnosis and their intake of high-GI foods – typically, high-carbohydrate foods such as white bread, potatoes and rice.

Researchers found people in the highest (fifth) intake group for high-GI foods were about 49% more likely to have lung cancer than someone in the lowest (first) intake group.

But drawing any firm conclusions from this is difficult. There was no increased risk for anyone in the intermediate intake groups, and there is no information we can use to give an equivalent food intake.

This study was a cross-sectional assessment of diet in people who had already been diagnosed with lung cancer. We don't know whether this is a reliable indication of lifetime dietary patterns, so it can't prove cause and effect.

Overall, the possible link between carbohydrates and lung cancer needs further investigation to see whether there is a direct link and, if there is, find out the possible cause.

On its own, this study does not provide strong evidence that "carbs are the new cigarettes".



Where did the story come from?

The study was carried out by researchers from the University of Texas.

It was funded by the National Institutes of Health, the Cancer Prevention & Research Institute of Texas, the University of Texas MD Anderson Cancer Center, and the National Cancer Institute.

It was published in the peer-reviewed journal, Cancer Epidemiological Biomarkers Prevention.

While the Mail's reporting was broadly accurate, it would have benefited from considering some of the limitations of this research, which cannot prove carbohydrates directly cause lung cancer.

So what's your $#@!ing point?

https://chriskresser.com/does-red-me...-inflammation/

Two different controlled trials have measured inflammation markers in response to increased red meat intake, and both have found that red meat does not elevate these markers. The first study concludes that increasing red meat consumption by replacing carbohydrates in the diet of non-anemic individuals actually reduces markers of inflammation. (1) The other study showed that in anemic women, inflammation markers on a diet high in red meat were not significantly different from those on a diet high in oily fish. (2) This evidence suggests that red meat is not more inflammatory than other meats for most people, and is potentially less inflammatory than dietary carbohydrates. However, I’d like to discuss a couple of other specific mechanisms that are often blamed for inflammation.

Neu5Gc

Despite the lack of controlled trials demonstrating that red meat is inflammatory, there has been recent concern over a compound in red meat called Neu5Gc. (3) Neu5Gc is a monosaccharide that acts as a type of signaling molecule in mammalian cells, and one of its functions is to help the immune system distinguish between ‘self’ cells and ‘foreign’ cells. (4) Humans lost the ability to produce Neu5Gc millions of years ago through a genetic mutation, although we still produce the closely related compound Neu5Ac. (5) Humans are unique in this respect, because most other mammals still produce Neu5Gc, which is why that compound is found in mammalian meat.

When humans consume red meat and milk products, we incorporate some of this compound into our own tissues, especially tissues that grow at a fast pace such as fetuses, epithelial and endothelial tissue, and tumors. (6) The concern is that most of us also have anti-Neu5Gc antibodies circulating in our blood, and some researchers have suggested that these antibodies react with the Neu5Gc in our tissues to create chronic inflammation, leading to chronic diseases such as cancer.

The problem is that researchers are nowhere near proving that hypothesis. Research is in the very earliest stages, and while some fascinating hypotheses involving this molecule are being generated, the studies needed to confirm or refute these hypotheses are nonexistent. Most of the studies done on the topic acknowledge that at this point, any role in chronic inflammation is speculative, but many who have cited their research neglect to acknowledge that limitation. Thus begins a new round of fear mongering at the expense of red meat.

In the absence of conclusive evidence one way or another, it can be helpful to remember that red meat has been part of the human diet for much of our history, and remains an important dietary element of many healthy cultures. For example, the traditional diet of the Masai was composed almost entirely of red meat, blood, and milk – all high in Neu5Gc – yet they were free from modern inflammatory diseases. (7) If Neu5Gc really caused significant inflammation, the Masai should’ve been the first to know, because they probably couldn’t have designed a diet higher in Neu5Gc if they tried.

These are the supplements Chris recommends in his book, Your Personal Paleo Code, for Adrenal Fatigue Syndrome.

http://store.chriskresser.com/collections/adrenal

Adrenal fatigue or hypoadrenia are terms used in alternative medicine to describe the unscientific belief that the adrenal glands are exhausted and unable to produce adequate quantities of hormones, primarily the glucocorticoid cortisol, due to chronic stress or infections.[1] Adrenal fatigue should not be confused with recognized forms of adrenal dysfunction such as adrenal insufficiency or Addison's Disease.[2]

The term "adrenal fatigue", which was coined in 1998 by James Wilson, a chiropractor,[3] may be applied to a collection of mostly nonspecific symptoms.[1] There is no scientific evidence supporting the concept of adrenal fatigue and it is not recognized as a diagnosis by the medical community.[1][2]

Blood or salivary testing is sometimes offered but there is no evidence that adrenal fatigue exists or can be tested.[1][3] The concept of adrenal fatigue has given rise to an industry of dietary supplements marketed to treat this condition. These supplements are largely unregulated in the U.S., are ineffective, and in some cases may be dangerous.[3]

LOL, are you a part of the coffee industrial complex or something?

Very few people around here buy the bull$#@! from the government funded science establishment, we recognize the benefits of alternative medicine and the destructiveness it causes to the institutions that control and profit from society.

In other words, science is extremely corrupt. People who come up with natural treatments that can't be patented that will cause billions of losses for companies that produce pharmaceuticals will obviously be treated harshly in the bull$#@! scientific literature.

[farreri]

That's ironic you say that when none of the low-fat diets promote coffee, but almost all of your low-carb diets do! What's it called, "Bullet Coffee"?!

Please list some of the benefits of alternative medicine.

Right, and most of those pro-saturated fat and cholesterol studies of late have been funded and ran by the animal products industry (conflict of interest). Many here complain about big Agra, but for some reason let big Cattle, Dairy, & Egg off the hook.

Coffee is a superfood, it's very healthy in small amounts - however a lot of people tend to over-drink coffee, some people drink 3, 4, 6 or 8 cups of coffee or more a day and this causes adrenal fatigue, which by the way is real.

Please list some of the benefits of alternative medicine.

We can cure and prevent diseases largely with natural substances and foods. Our body's can handle these things much better in most cases than a lot of things made in a lab. Natural treatments often provide more synergistic effects than what science gives us based on what happens in petri dish.

Let's pretend that in the future people stop eating carrots for some reason, maybe people start hating the color orange or something. Then let's pretend blindness was becoming a huge health problem in society. Then let's say somebody discovers that adding carrots to their diet prevents most cases of blindness that are occurring. They could become a carrot farmer and make pretty good money as this discovery takes hold, but the market would quickly fill in with other people farming carrots because under the law you can't patent a carrot and anybody can grow carrots.

So instead the guy puts out a bunch of anti-carrot propaganda, saying they taste bad and will kill you and only nerdy sexless people like carrots, at the same time the guy isolates the vitamins or substances in the carrot that prevent blindness, buys a patent and sells that as a cure and preventative for blindness. He makes billions of dollars this way because he has a monopoly on the cure for this disease, when anybody can grow carrots in their backyard. It would also be healthier if people just ate the carrots, because now there are side effects coming out for this carrot isolate he made and so he makes a new drug to help people with those side effects and makes billions more.

That is an analogy for the corruption of medicine, that is essentially how the entire industry works.

Big cattle and dairy actually like grain subsidies because it makes the feed cheaper, they win no matter what as long as the government is involved.

Those industries don't produce paleo food though, they feed their animals almost entirely on grains and often without any real pasture feeding.

A superfood that causes problems if you eat/drink too much of it doesn't sound so super to me. My advice when you hear someone claim something is a superfood, hold on to your wallet because superfood is today's new term for snakeoil.

adrenal fatigue, which by the way is real.

Can you show me a valid scientific link supporting your claim it's real?

We can cure and prevent diseases largely with natural substances and foods.

Most MD's I ever went to always talked about diet and dieticians are licensed medicine practioners, but most people rather take a pill than cut out the foods that taste so good to them, drink plenty of water, work on their stress load, and get adequate sleep. Yes, a lot of the diet advice MD's give out isn't very good IMO, but alternative docs give out conflicting diet advice among other alternative docs and most alternative docs have seem to have jumped on the unhealthy low-carb bandwagon while having a $#@! ton of questionable supplements to sell you.

So instead the guy puts out a bunch of anti-carrot propaganda, saying they taste bad and will kill you and only nerdy sexless people like carrots, at the same time the guy isolates the vitamins or substances in the carrot that prevent blindness, buys a patent and sells that as a cure and preventative for blindness.

Sounds like a lot of these alternative health gurus who are putting out a bunch of anti-fruit propaganda so they can sell you their unregulated BS supplements!

That is an analogy for the corruption of medicine, that is essentially how the entire industry works.

I understand how the industry works. I want to know what alternative treatments work.

Fascinating conspiracy theory, but studies showing too much meat is bad has been out since the 50's if not earlier. Most of the new studies lately seem to paint meat in a positive light and, coincidentally, most of these studies are being funded by the meat industry. Why doesn't that get much attention from liberty heads?

As the article in the OP noted:

eating large amounts

had one third higher risk of bowel cancer.

So what is the risk to begin with? If you are 60 years old, you have a 1.2% chance of getting it in the next ten years. http://www.cdc.gov/cancer/colorectal/statistics/age.htm

Increase that by one third and you have a 1.6% chance of getting bowel cancer.

More like the grain industry funded bull$#@! studies for decades showing meat was unhealthy (even though the meat they studied was grain fed), now everybody is sick and dying eating too many grains and sugar, and there is some semblance of good science shining through on occasion showing that good pastured meat is actually healthy and too many carbs are bad.

Did they? We do know the animal products industry funded studies as those studies say so on the study. Is everybody sick and dying eating too many grains and sugar, or from eating too many animal product. The SAD diet combines both of those foods.

It may be time to change the name of the forums to "Everyone who eats meat sucks, and Vegans are way better than those stupid humans forums."

Haha... but there really aren't many vegans or vegetarians here at all. In fact, every time farreri posts one of these threads, the same thing always happens... A truckload of meat-eaters comes along, then they all gang up and bash the things he posts, or they talk about how much they enjoy their steak.

I have to say... about 6 months ago, I would've been right there with you all, bashing his articles. I was a TOTAL meat-eater and I always said that I could never go vegan, because I love meat and dairy too much.

But I haven't had meat (with the exception of a little sea-food) or dairy in the last 5 months, and it was definitely one of the best decisions I ever made. I don't even miss meat/dairy. I'm just completely over it. It happened pretty quickly for me, in about a day, I just made the decision and I'm glad I did.

Seeing how horribly animals are treated did it for me. That, and realizing that from a biblical perspective, our original diet was basically vegan.

There are some very important differences. See, I couldn't possibly care less if someone goes vegan.....good for them! Something spurred their conscience and they obeyed it! If only half the US population did so we'd be way better off. I've had my own issues with the meat processing industry that has led me to buy from local farmers I know who do not do what appalls me.

But.

This whole 'meat eaters are evil and vegans are gods amongst men' thing is so asinine as to warrant as much ridicule as can possibly be leveraged by humankind.

I have less than zero problem with people who happen to be vegetarians or vegans. My goodness, my soul is probably plagued by the suffering of animals even more than theirs...but the moment one goes holier than thou they need stomped into dust, because the reality is we have been set up to require meat. Maybe some suffer themselves to avoid meat, and I'll agree that is noble, but bull$#@! like farreri here makes me want to go on an animal killing spree just to make the piece of (mod edit)

It is one thing to make a personal decision to suffer one's self to abstain from meat because of a principle one holds. This is something I consider nobe even if I do not entirely agree. But to act like every other human being on the planet is the scum of the freaking earth because they do not worship the same bull$#@! god she (he?) does is way beyond stupid.

If vegans acted like normal people, I would be 1000% more friendly to their line of thought. This holier than thou bull$#@! makes me want to go on an animal slaughtering rampage just to make the (mod edit) cry.

As to the biblical perspective, yes, humans were originally created to be vegetarians, but humankind $#@!ed up and were forced into carnivorism to demonstrate what they did wrong. At this point, it is biologically and theologically necessary to eat meat, because God made that a condition of survival after the fall. It seems apparent that we will revert to vegetarianism when elevated into our glorified bodies, but anyone who thinks we are post transfiguration today is bloody kidding themselves.

And anyone who acts "holier than thou" based on their ability to blatantly disobey God, deserves every ounce of contempt I can possibly muster.

Maybe you are 100% vegan, and if you are without being a complete $#@! about it, I admire you. The moment someone becomes an $#@! about $#@!ting right on God's face, I no longer give a $#@! about them or their bull$#@! opinions.
