Today's Health News
THURSDAY, Dec. 7 (HealthDay News) -- Eating a low-protein diet may protect against certain cancers, while a diet high in protein may increase the risk for malignancies, a new study suggests.
The results of this preliminary study show that lean people on a long-term, low-protein, low-calorie diet or who participate in regular endurance exercise training have lower levels of plasma growth factors and certain hormones such as insulin-like growth factor 1 (IGF-1). These substances have been linked to an increased cancer risk, especially premenopausal breast cancer, prostate cancer and certain types of colon cancer.
"We know there is a link between nutrition and cancer," said lead author Dr. Luigi Fontana, an assistant professor of medicine at Washington University in St. Louis. "There are certain cancers that are linked with levels of IGF-1, which is an important growth factor that stimulates the proliferation of cells."
If there are high levels of IGF-1, there's a greater chance that mutated cells will become cancer cells, said Fontana, who's also an investigator at Istituto Superiore di Sanita, in Rome, Italy. "We found that people following a low-calorie, low-protein diet have lower IGF-1 than lean athletes who eat a Western diet. This suggests that low protein intake may reduce IGF-1, independent of body weight," he said.
The study is published in the December issue of the American Journal of Clinical Nutrition.
For the study, Fontana's team looked at three groups of people. The first, made up of 21 lean men and women, ate a low-protein, low-calorie, raw food, vegetarian diet. The second group of 21 people did regular endurance running, averaging about 48 miles a week. These runners ate a standard Western diet that included more calories and protein than the first group. The third group included 21 sedentary people who also consumed a standard Western diet, higher in sugars, processed refined grains and animal products.
People in the first group averaged a daily intake of 0.73 grams of protein per kilogram of body weight. The runners ate 1.6 grams, and sedentary people ate 1.23 grams of protein a day. The recommended daily allowance for protein intake is 0.8 grams, Fontana said. That's about three ounces of protein per day for a 220-pound man.
The researchers found that people in the first group had significantly lower blood levels of IGF-1 compared with the runners or the sedentary people. High levels of IGF-1 have been linked to premenopausal breast cancer, prostate cancer and certain types of colon cancer.
In addition, lower IGF-1 levels are associated with increased life span in animals, Fontana noted.
Fontana thinks that if people ate more whole grains, beans, fruits and vegetables and far fewer animal products, they would be healthier. He recommends fish, low-fat dairy products and, occasionally, some red meat. This type of diet reduces total calories and the amount of protein consumed, and it also might result in lower levels of IGF-1.
"Many people in the United States and Italy are eating 50 percent more protein than what is recommended," Fontana said. "If we eat 50 percent more calories than recommended, we become overweight and obese. What happens if you eat 50 percent more protein than required -- we don't know."
He speculated that eating too much protein increases the risk for cancer and also accelerates aging, "but we need more studies to see if my hypothesis is true or false."
One expert also thinks that a high-protein diet increases the risk for certain cancers.
"We recently published a paper that also shows that a high-protein diet is bad for you. It reduces survival; it increases the risk of cancer," said Dr. Dimitrios Trichopoulos, the Vincent L. Gregory Professor of Cancer Prevention at the Harvard School of Public Health's Department of Epidemiology.
In that study, published online in the Nov. 29 issue of the European Journal of Clinical Nutrition, the researchers collected data on the diets of 22,944 healthy adults and found that eating diets low in carbohydrates and high in protein was associated with increased mortality.
Trichopoulos thinks that levels of IGF-1 may be the reason for the increased cancer risk. However, other factors may be at work, he added.
Despite his and Fontana's findings, Trichopoulos isn't ready to recommend a low-protein diet to reduce the risk of cancer or to live longer. Another recent study contradicted this finding, Trichopoulos said. "At this stage, we should wait for clarification," he said.

and this dumb fuck probably microwaves food everyday..that has to be good long term
he should worry more about the steroids that they are giving the cows and chicken

oh for fucks sake ive been saying this all along
LIFE = CANCER

Yep.
Just like you could be a smoker all your life and never catch lung cancer.........if you're due, you're due.....

BS.
it's a good thing you don't actually work out or eat a high protein diet, "Manninen dude" ::)

why cant we just live off water for fucks sake
theres only so much we can do ..

ALl this proves is no one know's shit about biology. I mean we have the concepts but were lacking alot of details. For anyone to act like they know is complete bullshit. We can only go with what we know for certain. Being fat is just a shitting way to live being inshape makes life alot more enjoyable.

igf-1 speeds up cancer growth, like gh, doesnt cause it.

Actually Adonis is right! carbs, sugar and fat is cheaper than protein
Junk food is pretty cheap in America, eating healthy is pretty pricey
on some levels that is why there are so much fat people in America, food is very cheap and you get very large portions.
for about $5-10 you can buy a filling meal of junk food.
a dozen donuts is probably $4 + $2 for a 2 liter coke

Everybody gets cancer multiple times in their lifetime.
What determines whether or not this becomes cancer in the sense we know it is the severity and number of genetic mutations (especially in the p50 gene) and one's natural genetic proofreading and repair machinery.

Me, I'm still waiting for the true adonis to show why a valid argument has to be true ::) ::)

Part of the problem with "cancer" is the loose defintions that are sometimes applied to it.
You need aberrant cell signaling and usually in human cells a 3 punch combination of problems to make a malignancy happen. Tumour suppressor proteins and genes are easier to mess with to help in induction of a cancer while mutating a proto-oncogene usually requires a much more specific mutation.
Furthermore, insofar as deciding what is going to cause cancer, they know very little to be absolutely true when it comes to cancer and what causes it. Eat healthy, try not to get fat, stay away from smoke and burned food, power lines, fuck you know even bananas can be carcinogenic.
Live and have fun. Try to stay healthy. If you get cancer, try to take care of it, that is about all you can do.
If anyone wants a great book about Cancer Biochem, PM me and I can let you on to a doozy. Really informative, although sometimes heavy. If you read it though, you will be miles ahead of other people in understanding this cellular condition they call cancer :D

In general, we know very little about cell signaling.
It is truly mind boggling how complex cell signaling truly is.

You are so correct man. It is kind of scary but neat at the same time.
From personal experience it can also really suck when trying to explain phenomena in experiments when you know for sure you don't have nearly all the imformation at your disposal. There will always be jobs in it though :)

Efficient too. Exactly the reason you don`t need over 700 lbs of meat,(300-350 grams of protein a day) to build 64 Ounces of muscle(amount for a hard training natural) in a year.
People are too dumb to realize this though.

naw that would be more like 700lbs of meat. 2lbs of meat or so a day = 350g protein, if meat is your only source.

haha i've been eating a lot of frozen foods since i moved into my apt., i'm not one that likes spending time cooking. I've easily been eating more fat than protein. i'm getting sick of that food though, going more towards sandwiches and pasta.

I have been eating very well. I get these Gigantic cookies from the store. hahahah...Egg Nog is out now too and I drink a lot of that as well.

Yes, I'm not denying that I probably eat way more protein than I need.
I've got the same reason as anybody- when I was new to bodybuilding, I read around, and it all seemed to point to high protein as the way to go. I am naturally sceptical and read things critically, so I treated my acceptance of this tentatively. Now, I do get insecure about cutting back on protein- I fear muscle loss.
Having said that, I believe it's working. I am still getting stronger, and I believe I am adding more muscle. So, why fix it if it ain't broke? I'd rather err on the side of caution.

High Protien=Not good.
At least I would say there's no point of a high protein diet. Carbs are the best source for energy.

Excessive protein over long time can cause other problems besides canser. Like cholesterol, believe it or not. Higher metabolism generally means shorter life. But this is all very individual-based, and also - one has to make choices in life and take risks. No one is forcing us to lift weights, down protein shakes and pin ASS, as well as nobody's forcing the other guy to eat at McD's all the time. Yeah, you can blame things on media, society and peer pressure...But if you do - you're just a week looser who can't accept repsonsibility for own actions.

TA, you keep talking about your 'principles', lay 'em out for us. We keep getting titbits, maybe you might be on the right track but nobody knows due to a lack of complete info.

Very much so. Keeps me alseep at night.

Read the fine print: "He recommends fish, low-fat dairy products and, occasionally, some red meat."
I don't know how others structure their high protein diet, but the above describes how I do it (plus 50g of protein per day from why shakes).
As far as cancer, get your antioxidents in (green tea, vitamin c, blueberries etc), keep your overall dietary fat intake low (less than 20% of the total), moderate (or eliminate) alcohol consumption, don't smoke, and your cancer risk rate will be less than 90% of the population.
-
And to add to the prior post, high fiber also.
The overall point remains, there are so many ways nutritionally and otherwise to reduce cancer risk, one should not be deterred from a high protein diet.
I would not be surprised if the bodybuilding poupulation (non-steroid) has a lower cancer rate than the overall population, notwithstanding high protein consumption.

carbs are key for strength.
Eat under 100g carbs for a week and see how strong you are.
Eat under 100g protein and high carbs and your strength will be good.

I'm still waiting to see this miracle diet where you grow muscle on less than 100g of protein per week (i.e., less than 15g per day). Let's see it or kindly retract your statement.

theres benefits to eating meat, Man!
if you're talking purely bodybuilding purposes, you're probably right, but red meat and some white meat sure is good for ya a few times a week :)

Non-steroid bbing population?.... And thats like what... 10% of us?
Otherwise AAS may speed up the rate of growth in cancer cells, thus increasing the risk.
