    I’ve heard of potential health issues from red meat consumption, but all animal products? That’s a first for me. Do you have any sources to share on this?

      Technically it can’t be all animal products, since honey is about 98% sugar, and despite the hate campaign currently hitting carbs, sugar is not quite as harmful (in and of itself) as it’s made out to be.

      But if we’re referring to all animal products in the sense of meat, dairy, and eggs - those three foods have nutritional properties that are all very similar and they do have some overlap in terms of health issues.

      The biggest thing they have in common is being a package deal with high amounts of saturated fat and cholesterol. Heart disease is generally the industrialized world’s number one killer, and all three animal foods initiate the onset and progress the state of heart disease.

      Then there are issues that are less settled, like to what degree do these foods cause various cancers?

      And then this one is even more in need of further study, but there might be a link between these foods and autoimmune disorders.

        I’m aware that there’s evidence of saturated fats having undesirable effects on your health. But plenty of meats are low in saturated fats (e.g. skinless chicken breast, or fish).

          Relatively low if you compare it only to other meats or animal products. So while you can choose animal products that might progress these chronic metabolic diseases slower, you are still advancing them. But there are lots of factors that complicate things. For example the health impacts of animal products also depend on how you cook them, and what you eat them with. Cured meats are unanimously considered one of the worst things you can consume, right up there with smoking. Steamed fish would probably be about the least harmful (except that fish have some of the highest levels of bioaccumulated toxins and heavy metals). Actually, bugs are likely the least harmful, for those who are comfortable with that. Eating a source of fiber mitigates some of the harm from animal products as shown in this video:

          https://m.youtube.com/watch?v=C08mqjMuwyY

          Further complicating things is that single nutrients often behave differently depending on context. For example antioxidants other than some of the essential vitamins have never been shown to produce their purported effects outside of laboratory conditions, and some supplemented sources of antioxidants have even been shown to be a little harmful. But when we test the whole foods that contain those antioxidants, we get data like how increasing leafy green consumption has been correlated with a longer life expectancy.

          And it’s similar for saturated fats and animal products. In the most established science on the matter you’ll see they don’t just talk about saturated fat alone - the science appears to show a relationship between the ratio of saturated and unsaturated fats consumed, particularly polyunsaturated fats. This book describes that science quite well-

          https://www.redpenreviews.org/reviews/eat-drink-and-be-healthy/

          But going back to that nutrients vs whole foods, there might be more than just the fats at play. This piece by Colin Campbell is a bit of a manifesto against nutritional reductionism, and suggests that the animal proteins themselves might play more of a role than we had thought:

          https://nutritionstudies.org/is-saturated-fat-really-that-bad/

          When you put whole diets to the test, what starts to become most consistent is how the most whole-plant-dominant diets by far achieve the most remarkable results. It’s apparent in the Adventist Health Studies, the Esselstyn Heart Disease Reversal diet, as well as Dean Ornishes full lifestyle intervention program. The latter two claim they can reverse heart disease, which is a controversial claim. More study is needed to prove whether that’s true or false, but regardless it’s still apparent that these fully plant-based dietary interventions do more than any others to restore people to good health.

          And it’s a thing where science and personal experience match. If you check out the online whole-food plant-based support communities, you see people routinely report almost miraculous changes to their health and wellbeing in a matter of weeks or even days. It’s the kind of thing that once you experience it fully enough, you don’t want to go back.

      Try watching the documentary “You are what you eat” on Netflix, it’s a good intro that covers the health risks of other animal products as well.

        I don’t get much time to watch videos these days so I’m not going through the Netflix series. Though it looks like it’s based off this paper, and that I can look through.

        They studied 22 pairs of twins, intervened by changing their diets so that one gets a vegan diet and the other an omnivore diet, then measured a bunch of stuff via blood and stool samples. I don’t see mention of how they correct for multiple hypotheses, but I’ll just give them the benefit of the doubt here.

        They found statistical significance in two places

        • LDL-C: Participants all start out in a healthy range, and they stay in a healthy range. So while the vegans improved on this measure, it also tells us that omnivores are perfectly healthy as well.
        • Fasting insulin levels: Same as LDL-C. Start off healthy, ended up healthy. We see the vegans having lower fasting insulin, but we don’t know if that’s a good thing or not when they’re already starting at 12.7 μIU/mL.

        So basically, the conclusion from the paper is that vegan and omnivore diets are both perfectly healthy, but you might gain slight benefits from going vegan.

          Thanks for looking that up. I’m no dietician or medical expert myself, so I have to go by the more easily digestible media. That does run the risk of being more sensationalised.

          One thing I did take away from the Netflix series was that both the omnivore diet and vegan one were designed to be well-balanced. Everything in moderation works well, I suppose.
