    SAN DIEGO – A trip to almost any bookstore or a cruise around the Internet might leave the impression that avoiding cancer is mostly a matter of watching what you eat. One source after another promotes the protective powers of superfoods, rich in antioxidants and other phytochemicals, or recommends the diets of Chinese peasants or Paleolithic cave dwellers.

    But there is a yawning divide between this nutritional folklore and science. During the past two decades the connection between the foods we eat and the cellular anarchy called cancer has been unraveling string by string.

    This month at the annual meeting of the American Association for Cancer Research, a huge event that drew more than 18,500 researchers and other professionals, the latest results about diet and cancer were relegated to a single poster session and a few scattered presentations. There were new hints that coffee may lower the risk of some cancers and more about the possible benefits of vitamin D. Beyond that there was not much to say.

    Walter Willett, a Harvard epidemiologist who has spent many years studying cancer and nutrition, sounded almost rueful as he gave a status report. Whatever is true for other diseases, when it comes to cancer there was little evidence that fruits and vegetables are protective or that fatty foods are bad.

    About all that can be said with any assurance is that controlling obesity is important, as it also is for heart disease, type 2 diabetes, hypertension, stroke and other threats to life. Avoiding an excess of alcohol has clear benefits. But unless a person is seriously malnourished, the influence of specific foods is so weak that the signal is easily swamped by noise.

    The situation seemed very different in 1997, when the World Cancer Research Fund and the American Institute for Cancer Research published a report, thick as a phone book, concluding that diets loaded with fruits and vegetables might reduce the overall incidence of cancer by more than 20 percent.

    After reviewing more than 4,000 studies, the authors were persuaded that green vegetables helped ward off lung and stomach cancer. Colon and thyroid cancer might be avoided with broccoli, cabbage and Brussels sprouts. Onions, tomatoes, garlic, carrots and citrus fruits all seemed to play important roles.

    In 2007, a major follow-up all but reversed the findings. While some kinds of produce might have subtle benefits, the authors concluded, “in no case now is the evidence of protection judged to be convincing.â€

    The reason for the change was more thorough epidemiology. The earlier studies tended to be “retrospective,†relying on people to remember dietary details from the distant past. These results were often upended by “prospective†protocols, in which the health of large populations was followed in real time.

    The hypothesis that fatty foods are a direct cause of cancer has also been crumbling, along with the case for eating more fiber. The idea that red meat causes colon cancer is shrouded in ambiguity. Two meta-analyses published in 2011 reached conflicting conclusions — one finding a small effect and the other no clear link.

    If hamburgers are carcinogenic, the effect appears to be mild. One study suggests that a 50-year-old man eating a hefty amount of red meat — about a third of a pound a day — raises his chance of getting colorectal cancer to 1.71 percent during the next decade, from 1.28 percent. Spread over a population of millions, that would have an effect. From the point of view of an individual, it barely seems to matter.

    Trying to tweeze feeble effects from a tangle of variables, many of them unknown, inevitably leads to a tug of war of contradictory reports. (As the San Diego meeting was winding up, a new paper on high-fat diets and breast cancer suggested there might be a connection after all.)

    With even the most rigorous studies, it is hard to adjust for what epidemiologists call confounding factors: Assiduous eaters of fruits and vegetables probably weigh less, exercise more and are vigilant about their health in other ways.

    Some of this can be sorted out with randomized controlled trials, with two large groups of people arbitrarily assigned different diets. But such studies are expensive, and the rules are hard to enforce in the short term — and probably impossible over the many years it can take for cancer to develop.

    The emphasis at the meeting was on other things: new immunotherapies, the role of chronic inflammation and the endlessly intricate subterfuges of cancer cells. With his focus on nutrition, Willett seemed like the odd man out.

    “Diet and cancer has turned out to be more complex and challenging than any of us expected,†he said, standing thin as a rail at the lectern.

    There were some reasons for optimism. A study last year suggested that while eating lots of produce had no effect on most breast cancers, vegetables might reduce the occurrence of a type called estrogen-negative. Cutting back on milk and other dairy products might lower the risk of prostate cancer.

    As epidemiologists began to follow the health of younger populations, Willett hoped that more dietary influences would yet emerge.

    That evening at a reception hosted by the M.D. Anderson Cancer Center, guests partook of a sumptuous buffet that included thick slabs of roast beef, a variety of rich cheeses and generous servings of wine. Afterward came the cancer research association’s grand celebration known for its dessert buffet.

    The next morning the scientists were back at the meeting, coffee in hand, rushing from session to session.

    These studies findings change every couple of years. What's good for you now will be bad for you next year after looking at studies and what's bad for you now will be good for you next year after looking at studies.

    One minute they said Omega 3 fish oils did everything for you including helping your prostate, then a few months back, they say it could hurt your prostate. :facepalm:

    I eat shit loads of saturated fats and i'm not overweight and have great cholesterol and blood pressure. I try to avoid sugar and processed foods. I go for walks sometimes. this seems to be working for me.

    The discrepancies among studies are due to poor research or due to media overhyping effects of something. If you actually look at papers, you can see that the effect that researchers report are quite small for many things but the media and food advocates overhype it. Don't confuse the message with messengers. Lots of people have vested interest in promoting all these "super foods" and supplements. It's a multi-billion dollar business.

    remember when margarine was a healthy substitute for butter and you were crazy if you still ate butter? now margarine is considered poison and all the saturated fat, CLAs and vitamin K in butter are great. it's definitely hard to keep up.

    I think sugars are bad for you and can hurt you. Ving on here showed me some good stuff on sugar. But I'm with GreyT, eat whatever you want in moderation or extra on certain holidays just remember to always workout and you'll be fine. I workout and play hockey often and eat whatever I want and my numbers are good. I just stay away from most sugars.

    Remember they key is to ALWAYS......

    From now until the end of time you'll only need to know a few things....

    -eat a good variety of real food and avoid processed crap.
    -don't overeat.
    -get off your ass.

    Doesn't make for a good book, but that's it.

    Boooooooooring.....

    maybe i'm turning into a no-good hippie but I think stress management is very important for health and think being overly stressed (as most people are today) could easily play a role in cancer. I've been learning some breathing exercises and researching a bit about meditation. a good massage never hurts either, with or without the happy ending.

    Margarine is not considered poison. It's actually recommended by the American Heart Association. The reason why margarine got a bad rep was because some manufacturers long time ago made it with trans fats. Now they make it with no trans fats and many contain just olive oil. Light margarine is healthier than any butter. Butter is 80% cow milk fat. It's horrible for you.

    vitamin k- k2 in butter only from grass fed pastured cows, grass fed milk as well

    sugars are actually very important for optimum cell function - honey, certain fruits such as oranges

    pretty much

    "vitamin k- k2 in butter only from grass fed pastured cows, grass fed milk as well"


    i know...and it's almost impossible to get grass fed dairy in Canada. we have some stupid laws against importing dairy so we can't get Kerry's Gold or any of the good brands. I've found one brand that i get which is supposed to be mostly grass fed, supplemented with some grains during the winter. it's all right but it doesn't have that really dark yellow look that i want.

    Yeah the brain needs glucose which can come from fruits, etc but the tons of sugar and processed foods taken in every day by people is just not good. I mean everyone makes their own decisions, I myself just try to stay away from most of it.

    every few months articles are published in all the "health" magazines about how only green teas are full of anti-oxidants and other specialized chemicals . the prices for japanese green teas shoot thru the roof (Teavana sells Gyokuro for $10/oz. How much is pot lately?) but if you compare tea types guokuro contains approx 46mg of the catechin anti-oxidant, while orange pekoe (e.g. Liptons) has the same amount of catechin anti-oxidant and sells for $2.00/oz...

    i like green and black teas but if i'm looking for the alleged heath benefits, Lipton is healthier for both me and my wallet.

    pretty sure sucrose is too big to pass the brain-blood barrier, so fruit sugar as well as starches have to be digested into simpler sugars first. as long as you have to digest it first, you will get glucose from starches as well as from fruits.
