Definitive conclusions shouldn't be derived from observational studies only. Also, the methodology used is very questionable.

We should be more critical about matters concerning our diet, as studies like the former will be used by the media and professionals to back potentially life-changing advices.

Earlier quoted context omitted.

Did you read the article? The analysis and results treats then separately: "processed meat: you would increase your risk by 0.4% over 10 years, 1.02% over 20 years and 1.74% over 30 years red meat: 0.17% over 10 years, 0.41% over 20 years and 0.62% over 30 years" > The additives in the latter have been shown definitively to do harm, whereas there is less evidence about the former. The article is evidence of their rel…

I haven't read the article yet, but going from the headline, I certainly assumed they were claiming the same/similar risk for both red and processed meat. From the summary you gave, it certainly does seem like a click-baity headline. Personally I would have hoped for better from the NHS (even if I wouldn't have expected it).

I’m sorry, but that’s simply an unwarranted assumption.

Essentially nothing: for an individual? Yes. For a population? No.

You or I may not care about a 0.62% increased CVD rate for ourselves over 30 years, but that does translate to 6,200 extra possibly-preventable cases of CVD per million people. That's about 76,000 diagnoses annually in the US alone.

Eh? The figures given are clear (and yes, I've read the article by now) - the risk associated with processed meat is much greater than that with red meat.

You should really include that this was under the assumption of only 2 servings a week, where a serving is about 3.5 ounces. I wonder how the rates change when you assume 2 servings per meal, which seems more in line with peoples actual diets.

How strong is this effect relative to other effects though? With small effects, you get an increased risk of error in the analysis as there could be confounding variables not fully accounted for, reporting errors, etc.

How would this compare, for example, to not smoking, drinking less alcohol, wearing sunscreen, safe sex, not exercising enough, etc.

(Picked things that I think we have a high standard of evidence for and fairly large effect, but that people often neglect due to wanting to do the harmful activity, as with red meat)

For years low salt recommendations were justified based on lessened harm "on a population level" even if individual gains were small. Now it seems that these recommendations were wrong, according to Cochrane reviews.

Smoking increases lung cancer risk 15x-30x, comes at a steep tax-inflated price and people still won't give it up.

I basically read this as "it's ok to eat meat/sausages/whatever".

Welcome to the world of nutrition science, where the methodology is shoddy, the evidence is poor, and the recommendations are ridiculous.

> ... completed a food questionnaire and then were followed up for around 20 years

FFQ are useless. I barely remember what I ate 2 days ago.

This way of interpreting the data is misleading. For population, it still could mean nothing. People are not living in an isolated environment just eating red meat or processed food and do nothing else. At the population level there are way more factors need to be considered. You can't even imagine how many things in the society will be impacted if people stop eating red meat or the processed food. CVD will be the least of concern at the population level.

So, yes, this tiny effect size means nothing.

Moreover, this tiny effect size could be much smaller than noises in the data.
