Nitrates in cheese
I noticed that most "big pieces of" cheeses contain preservatives with
the codes in the range from E249 to E252. They have in common that they are different forms of nitrates. I thought that they should be avoided because of the cancer risk. Checking the web site of a major dairy company, I read that "only very small or no amuonts of nitrate" remains in the product after processing and that "cheese does not contain the type of nitrate that may transform to nitrosamine". Do you know whether this is correct or not? I am considering whether I need to only eat cheeses without any preservatives. Thanks. |

Since there are plenty of nitrate free varieties are you limiting yourself much by taking a conservative approach? |

Nitrates, low carb and cancer ( Nitrates in cheese)
This is not really a response to a post in the "nitrates in cheese"
thread. Having followed up on my original query by checking the numbers, it strikes me that I have read about the link between "red meat" and cancer a few times. The abscence of cancer in several native groups with very high consumption of meat made me curious about this connection. I don't dispute the scientific findings, but is it because of the nitrates from preservatives and processing techniques? Low carbers might do well from those kind of products, including preserved meat, smoked fish and bacon. |

It is useful to bear in mind the publication on false [medical] research findings.... http://medicine.plosjournals.org/per...l.pmed.0020124 Why Most Published Research Findings Are False John P. A. Ioannidis Summary There is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true when the studies conducted in a field are smaller; when effect sizes are smaller; when there is a greater number and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance. Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true. Moreover, for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias. In this essay, I discuss the implications of these problems for the conduct and interpretation of research. Competing Interests: The author has declared that no competing interests exist.

E-mail: Published research findings are sometimes refuted by subsequent evidence, with ensuing confusion and disappointment. Refutation and controversy is seen across the range of research designs, from clinical trials and traditional epidemiological studies [1–3] to the most modern molecular research [4,5]. There is increasing concern that in modern research, false findings may be the majority or even the vast majority of published research claims [6–8]. However, this should not be surprising. It can be proven that most claimed research findings are false. Here I will examine the key factors that influence this problem and some corollaries thereof.

How about a different interpretation? It's the carbs + the red meat. |

The abscence of cancer in several native groups with very high consumption of meat made me curious about this connection. Where such groups have very low carb traditional diets. I don't dispute the scientific findings, but is it because of the nitrates from preservatives and processing techniques? The most obvious traditional meat diets are also ones that do not use nitrates to preserve their meats. Sun drying, salting, fermenting, the array of preserving used is bewildering. But use of nitrates is only a few centuries old. Because of this I hesitate to blame nitrates. Those high meat diets that are high risk appear to be "red and potatoes" folks. Blaming the combination of high fat and high carb seems the way to go. Low carbers might do well from those kind of products, including preserved meat, smoked fish and bacon. There are certain people who react poorly to nitrates. Those who know they have such an issue should have already been avoiding nitrates before starting to low carb. Those who follow the Atkins process as written to include the eliminate and challenge aspect can discover if they have problems with nitrates. Anyone with problems should avoid nitrates. Having everyone avoid nitrates because some have problems with nitrates is a paleolithic approach. It's conservative and effective, but it is unnecessarily restrictive in some cases. Will some benefit by avoidance? Yes. Will all benefit from avoidance? I do not think so. How to tell if you'll benefit by avoidance? By dropping from your diet for at least a week then reintroducing, standard issue eliminate and challenge from Atkins and several other plans. If you feel better by the end of the elimination period and/or feel worse when you reintroduce (it's easier to tell getting worse than to tell getting better) then you know you'll benefit from avoidance. I don't think there's a big downside to avoiding nitrates. They weren't used until recent history (recent in terms of thousands of years, not briefer centuries like refined flour and not longer tens of millenia like the introduction of grain agriculture). I tried the elinimation process and discovered I don't have ill effects, so I don't avoid preserved meats. This might be a mistake on my part. |
