Does Eating Organic Food Help Prevent Cancer? (usatoday.com) 151

An anonymous reader quotes USA Today: People who regularly eat organic food are less likely to develop cancer than those who don't, according to a new study out of France. A team of researchers studied 68,946 adult volunteers from France who provided information on how often they ate organic food, drinks and even dietary supplements. Participants were given a score, based on how often they eat organic food ranging from "most of the time" to "never" or "I don't know." During two follow-up appointments, one in 2009 and another in 2016, the researchers then tracked cancer diagnoses, the most prevalent being breast cancer. Other cancers observed included prostate cancer, skin cancer, colorectal cancer, non-Hodgkin lymphomas and lymphomas.

People who reported higher organic food scores were less likely to be diagnosed with cancer than the rest of the group. For example, those who consumed the most organic food were 25 percent less likely to have cancer, according to the research. That number grew to more than half when looking at cases of non-Hodgkin lymphoma.

        It's even simpler than that: Organically grown food is devoid of the poisons used to grow non-organic food: chemical pesticides and genetic modification. All those poisons sprayed on non-organic crops are damaging to human bodies. And over time, those damages accumulate into an greatly increased risk of severe bodily malfunction.

        • You mostly have it right, you just switched two things.
          Regular food is protected from commercially relevant pests by *insecticides* targeted very specifically to those particular insects, such that a very small amount does the job. Organic produce is treated with toxins such as extract of Deadly Nightshade, which is a general toxin rather than than an insecticide. Because it's not targeted to specific insects, Deadly Nightshade and the other organic toxins are far more dangerous to humans and have to be use

        • Organic does not mean pesticide, fungicide or any of those cides free. What it does mean is you have to use certain ones. Most of the organic pesticides are horrible to humans, compared to the synthetic pesticides.
          Now where you get less of them, is that pesticides are mainly used on younger plants, and organic plants tend to be harvest when they have aged more, compared to non-organic, so it is more likely that the pesticides have been incorporated into the plants, and made into something else, or have b

          Organic labeled food often have higher levels of known poisons than conventionally grown food. Those poisons are damaging to human bodies as you put it.
          Most poisons doesn't accumulate.

      • That's mostly down to centuries of selective breeding rather than fertilizer use. You would see a much better comparison between heirloom varieties and modern commercial varieties. Though some foods have higher per-fruit yield and nutrition through selective breeding - e.g. avocados.

        • I did take the time to specify results from the same seed.

          Instead of repeating pap you heard a bunch of times, (golly, I might have already heard it to!) you could always grow a vegetable garden and do a comparison with seeds from the same packet.

          Even without organic vs conventional you can do the same sort of experiment with water; grow two tomato plants in your garden, give one the amount of water that conventional farmers apply, give the other one the least amount of water to maintain plant health. Easy

    • It's a difficult variable to keep independent of other variables. Ie, who eats a mostly organic diet but changes nothing else whatsoever in their lifestyle? Also, organic food is more expensive meaning those who buy it tend to be wealthier, and wealth has a strong correlation to better health.

    • by HiThere ( 15173 )

      I'd guess, unless it's a very strong effect, that it's because those who eat mainly organic food are also likely to do other things that they feel will act to make them healthier.

      That said, one should never believe claims that some pesticide is safe "at measured levels", because you aren't exposed to just one. (One also shouldn't strongly disbelieve the claim. It's just that this is a claim where usually the only available evidence is manipulated by someone who stands to profit by selling the stuff.)

    These studies are really hard to do. I know they tried to control for a lot of stuff but people who eat organic are generally people who not only try to live a healthy lifestyle, but actually spend more money to do it.

    You'd expect them to have a lower cancer rate.

    • They did look at a lot of other common factors. The full study is available to read. Here are some of the caveats:

      When considering different subgroups, the results herein were no longer statistically significant in younger adults, men, participants with only a high school diploma and with no family history of cancer, never smokers and current smokers, and participants with a high overall dietary quality, while the strongest association was observed among obese individuals (although the 95% CI was large). The absence of significant results in certain strata may be associated with limited statistical power. Regarding the latter association, previous occupational data have indicated a potential interaction between obesity and pesticide use on cancer risk. It can be hypothesized that obese individuals with metabolic disorders may be more sensitive to potential chemical disruptors, such as pesticides.

      Negative associations were observed herein between the risk of cancer and combining both low to medium diet quality and high frequency of organic food consumption. The association between cancer risk and combining both a high-quality diet and high frequency of organic food consumption approached statistical significance. One hypothesis may be that higher intake of pesticide-contaminated products may partly counterbalance the beneficial role of high-quality foods among individuals with a high dietary quality.

      Some limitations of our study should be noted. First, our analyses were based on volunteers who were likely particularly health-conscious individuals, thus limiting the generalizability of our findings. NutriNet-Santé participants are more often female, are well educated, and exhibit healthier behaviors compared with the French general population. These factors may may have led to a lower cancer incidence herein than the national estimates, as well as higher levels of organic food consumption in our sample.

      One of the things that stands out the most is that if you already have a high quality diet, the results are no longer statistically significant. It's not a bad study, but of course the reporting on it jumps to conclusions that might not be true.

    • I know they tried to control for a lot of stuff

      How do you know that?

      • It is impossible to control for confounders.

        Sure, most studies try to do it by running the Cox multivariate analysis model, checking residuals, and then claim they are done. This is a standard feature of the statistical package. You can use it even if you don't fully understand the limitations.

        The problem is that the Cox model assumes the confounders are: linear, independent, and time-invariant. But we know that for many health-related parameters, none of these three conditions hold. Dose/response usually f

      They are basically impossible to do in this form. You can never control for all the factors that also have an influence. What you can find is that people eating organic food get less cancer. What you cannot find is whether the organic food causes that, unless you do a double-blind study, where one group gets real organic food and the other gets fake organic foods. Then you do that for 50 years or so and you get meaningful results if your groups are large enough, i.e. at least 100 people each. Good luck with

    • The interest in this article is really : if i switch to organic food will it improve my health?

      The answer is maybe yes but it is only part of the lifestyle changes you would need to make such as regular exercise.

      It's not a silver bullet but a better diet is part of the answer. Every one seems to be talking about pesticides, but organic will also include less use of preservatives that are used to increase shelf life.

    It's also very possible that people who eat organic food are just more cognizant about nutrition, health, and they food they eat. I'd like to see a study of two groups who both eat healthy and excercise, but one group eats organic food. Not slamming organic food, but I am skeptical.

    First is Self Reporting. This study did NOT find that people that ate more organic food got less cancer. Instead it found that people that CLAIMED to eat more organic food got less cancer. That desire tends to be highly correlated with education, wealth, and health consciousness.

    Second the availability of organic food is almost non-existent for the poor. You can't make that claim if you live in a food desert of a slum, next to a toxic waste dump because the grocery stores in those neighbourhoods do not carry organic food.

    I am willing to bet that people that claimed to eat organic food also had much better living conditions in general. I would be surprised if they were not less likely to smoke, drink, live next to toxic waste dumps, live in slums, live next to smoke filled factories, etc. etc.

    Studies of this type are good only to convince people to fund a REAL study where you take half the people and give them organic food and the other half regular food.

    Then measure the result in 10 years.

     

    • Yes, this study once out was almost immediately and publicly critiqued for its inconsistencies and poor methodological approach. And for good reasons.

      Releasing it as is was a huge mistake. It gave room to a lot of people for instantly using counter-fallacies and trying to claim the opposite: that eating organic food doesn't make a difference, which obviously is an even worse fallacy than the initial claim. Not being able to rigorously prove a danger doesn't make it suddenly safe. I'm observing a current tre

      • Considering the sheer number of published studies today, if you use the results of a single study to live your life by, then you're an idiot, independent of your socioeconomic status.

        Like getting your news from a single source, not factoring in the value of many studies is a mistake on the order of parroting the viewpoint of a single 24 hr news source.

        • Many studies are not necessarily better if they are all sloppy. The problem in nutrition is that most studies are just observational. The controlled trials are often done on animals, and/or short duration, and/or small, and/or poorly controlled. Ideally, you'd want to have good control, on large groups of humans, for most of their life. That's just not possible.

           

    • Indeed! Here's a review of this paper by Australia's well regarded nutritionist Rosemary Stanton, which independently has been assessed as presenting "a fair, balanced and accurate assessment of the research study.": https://theconversation.com/re... [theconversation.com]

      Another way to look at the study findings is that if you are an uneducated older woman who smokes and has a low overall dietary quality, you may have a higher risk of Non Hodgkin's Lymphoma and breast cancer, particularly if you are obese!!

    • Instead it found that people that CLAIMED to eat more organic food

      That is not a major problem. Sample sizes take care of pathological liars, as do the basis of studies that have no significant impact on the person being studied. I.e. you're not being judged. They aren't asking you to list your sexual fetishes in decreasing order of preference.

      Second the availability of organic food is almost non-existent for the poor.

      Completely irrelevant given the findings that were made: Correlation between consumption of organic food and cancer rate. They did not claim one causes the other.

      I am willing to bet that people that claimed to eat organic food also had much better living conditions in general.

      You don't need to bet. The study asked:
      Higher organic food scores were

      • Higher organic food scores were positively associated with female sex, high occupational status or monthly income per household unit, postsecondary graduate educational level, physical activity, and former smoking status

        And yet, in their conclusion they write: "promoting organic food consumption in the general population could be a promising preventive strategy against cancer"

        They could also have written instead: "promoting organic food consumption in the general population could be a promising way to increase monthly income per household unit"

        These are both associations they have found.

        • Indeed it could be.

          Great thing about words like "could" they imply possibilities. It is possible, just not proven here. If you want to look at the actual conclusions of the study then read the sentences as they are written in english, and look for those that deal with the conclusions from the data rather than possible explainations.

    The background cancer rate is one in three. So, with any environmental factor, the numbers are clouded with a lot of noise.

    More likely people who eat organic food think about their health more than people who don't care what they eat. People who make organic choices are likely eating more vegetables, which has already moved the needle on their cancer risk. As an individual, you can't tell if this little thing or that little thing will really lower your cancer risk. What does work is eating like a sane person, exercising, and keeping your alcohol intake in the moderate zone.

    Diet surveys are notoriously poor in reliability.
    They are lazy and just done because they cost little. They generate bad science.
    Self-reporting over long periods does not work, the surveys are not rigorously validated or are not broadly usable. The questions are often vague and people interpret them differently.

    This does not apply just to this study but correlational studies in nutritional research as a whole.
    Nutritional research often and notoriously produces poorly replicable results that keep flipping back and forth and the enthusiastic coverage of these flips in popular media erodes public trust in the scientific method.
    Until full expert consensus is formed, these lazy studies should not be reported outside scholarly journals.
