'Is Eating Red Meat OK, After All? Probably Not' (harvard.edu) 185

Remember last month when "an international collaboration of researchers" suggested there was no reason to reduce consumption of red meat? Here's a response from Frank Hu, chairman of the Nutrition Department at the Harvard T.H. Chan School of Public Health: The recent guidelines published in the Annals of Internal Medicine should not change existing recommendations on healthy and balanced eating patterns for the prevention of chronic diseases. Guidance to reduce red and processed meats is based on a large body of evidence indicating that higher consumption of red meat -- especially processed red meat -- is associated with higher risk of Type 2 diabetes, cardiovascular disease, certain types of cancers, and premature death.

While this guidance is supported by both national and international organizations, including the American Heart Association, American Cancer Society, and the World Health Organization, consumers should know that the new guidelines were released by a self-selected panel of 14 members. Furthermore, when my colleagues and I closely reviewed the studies informing the panel's decision, we saw that their findings contradicted their guidance. In short, the three meta-analyses of observational studies actually confirmed existing evidence on the potential for health benefits when cutting back on red and processed meats. However, because they based their analysis on a measure of three servings of red meat per week, the effects of an individual reducing consumption appeared small. But if you consider that about a third of U.S. adults eat one serving or more of red meat each day, the potential health benefits of reducing consumption become much greater...

[N]utrition research is complex, and rarely do [its findings] reverse so abruptly. That's why it's so important to look beyond the headlines at the quality of the evidence behind the claims. Still, the publication of these new guidelines in such a prominent medical journal is unfortunate as it risks further harm to the credibility of nutrition science, eroding public trust in research as well as the recommendations they ultimately inform.

            How many horses roam the plains now that people no longer use them for labor?

            You'd need a drastic reduction in the number of people to avoid the extinction of domestic animals that were no longer of use to people. (Even that might not work, as they've been bred to be useful, not to survive. But I suppose you could import some antelope of various types and bring back the bison.)

            At the time of the US civil war it was figured that a person required 40 acres and a mule to be above poverty level at farming. Of course, it depends a lot on the quality of the land, and the best land has had cities built on top of it.

            Complex systems resist simple solutions. But one simple solution that's always available is total failure. Dairy cattle would go extinct in two generations without human intervention. Beef cattle haven't been quite that specialized, but they're headed that way. There are almost certainly some small groups that haven't been specialized that way, but those are in small isolated locations. (Or outside the US, and forbidden import. India may well have lots of cattle that can fend for themselves.)

                Yeah, but even Africa is finding their wild species going extinct. Still, they probably have local breeds of cattle. But I live in the US, and if they aren't re-wildable here, they aren't going to be a part of the solution here. I can't address Europe or the Scandinavian countries. Or even Canada. But they tend to have the same domestic animals that the US does. Perhaps they insist that the animals be less specialized, but I have my doubts. Still, small farms may maintain their own localized strains

      To be clear, cooking food is processing it, and we've been doing that since the pleistocene epoch. It was a serious benefit that may have allowed our brains to grow bigger.

      Instead of saying "processed foods are bad," it's probably more accurate to say that foods mainly made of sugar and low-quality fat without many vitamins are bad. Or even more precisely, they don't have much good in them, like eating styrofoam.

      Because actually, processed foods are very good. And bad. You can't know without more detail.

          By definition, "too much" of ANYthing is "bad." That said, salt/sodium being bad has been entirely overblown. Current science shows that sodium isn't really a problem except for the very small portion of the population that has sodium sensitivity. If you don't fall into that category, and you probably don't, salt is fine in as much of a quantity as you prefer.

Those recommendations caused an explosion of obesity, diabetes, heart disease, and cancer - all metabolic disorders caused by the insulin resistance that resulted from those recommended dietary changes.

    Nutritional sciences are a low-quality research field that is struggling to produce any reliable results and that has screwed up time and again. Things told to the world as strong recommendations have repeatedly been found wrong, misleading, based on bad data or methods including the absolute beginners mistake of mistaking correlation for causation, and, yes, "found" by corrupt "scientists" in the pocket of some industry.

    Hence, I am now going with the base, time-honored advice: Most things are o.k. to eat, if you make sure your diet is diverse and you do not have something that dominates. It is also perfectly fine to eat things you like, even if that happens to be fast-food or sweet or fat things, as long as they do not dominate. Eating things you like is an immediate quality-of-life win. Other than that, I will ignore the nutritional sciences until they have cleaned up their act. They seem to be doing far more harm than good these days, wit some people in outright panic whenever some new "recommendation" comes out.
