    Since the study was done on Seventh Day Adventists, it's worth noting that they are all vegetarian, so no meat based protein options here...

    • beering · 4 days ago

      About half of the study participants were non-vegetarian, IIUC. I wonder if they found any correlation after slicing by vegetarianism?

        A core part of the scientific method is that you attempt to isolate a single variable at a time. If anything, all this suggests is that this was a better diet-controlled sample population for measuring the correlation of eggs and Alzheimer's than the general public. That said, the methodology of this study does not allow for inferring a relationship between Alzheimer's and meat consumption in either direction.

          It is very difficult to do that in biological systems where doing A in isolation can have the opposite effect of doing A while also doing B.

          • thayne · 4 days ago

            There could be an interaction with the diet though. For example, what if the nutrient in eggs that prevents Alzheimer's is something that also occurs in meat?

            Also, it seems likely that among this population many of those who don't or rarely consume eggs are vegan or almost vegan, so it might be more accurate to say that veganism is correlated with Alzheimer's.

              1. They ran a sensitivity analysis that removed vegans yet still got the same result, so the egg gradient is still there among non-vegans.

              2. They modeled swapping eggs for nuts/seeds/legumes and saw the same risk reduction. (Table 4)

                I think the table isnt clear, but I think the claim for 2 is that nuts(ect) did not show the same reduction - the egg finding held up.

            Adventists are okay with meat as long as it’s kosher generally.

            I think the bigger factor is that they’re teetotalers.

            My data points, though: two of my vegetarian teetotaling Adventist family members died of Alzheimer’s. The lifestyle is clearly not a cheat code for defeating dementia.

              I guess I gotta be the one to ask -- so do you recall if they ate eggs ?

              • keanebean86 · 4 days ago

                I grew up SDA. We ate eggs. Meat (beef, chicken, fish with scale and fins) was not forbidden but it was looked down upon. Potlucks were the worst since i was (am) a picky eater. No meat in sight. Mostly grey lumps in white gravy-ish sauce. I would survive on shells and cheese, mashed potatoes, and fruit salad.

                It's possible we were just bad SDAs though. I've met some hardcore SDAs. I imagine how I felt about them was how "regular" Christians felt about me.

                Sorry, this is way more information than you asked for...

                • EdwardDiego · 4 days ago

                  They do. These days generally the main prohibition is pig derived products, but plenty of SDAs still choose to be vegetarian. I'm not an SDA, but my daughter is.

                eggs are a highly concentrated natural source of choline. meat does contain choline but nowhere near as much as eggs.

                drawing the connection between cholinergic activity and alzheimers is left as an exercise for the unaware reader.

              • tfwnopmt · 4 days ago

                Cancer is also inversely correlated with alzheimer's.

                Phrased another way, egg consumption is correlated with cancer.

                • recursivecaveat · 4 days ago

                  Not necessarily. Looking before crossing the street is inversely correlated with getting hit by a truck. Getting trucked is inversely correlated with getting mauled by a lion (most places with wild lions are light on road traffic). Doesn't mean that looking both ways will increase your odds of becoming lion chow though.

                    • thin_carapace · 4 days ago

                      alzheimers must be a byproduct of some process the body uses to fight cancer. thank you so much for sharing this article, it is the most interesting physiological discovery I've heard in a long time. next steps we need to identify whether this hypothetical anti cancer mechanism is selective or constantly active. the plaques were a dead end but not a dead end!!!

                  > In addition, to evaluate potential bias because of unmeasured systematic differences between consumers and nonconsumers, we conducted a sensitivity analysis excluding vegans. Vegans comprised a substantial portion of the zero egg consumption group, which could disproportionately influence this group, and they often differ in other lifestyle or health-related characteristics.

                  So they eliminated vegans from the sensitivity analysis despite them comprising a substantial portion of the no-egg group.

                  If the analysis doesn’t hold with vegans included, it’s probably saying a lot about dairy rather than eggs.

                  • s1artibartfast · 4 days ago

                    They said it held up with and without vegans, getting the same result.

                    > Results from the sensitivity analysis excluding vegans remained very consistent with the primary findings (Table 3). The HR for consuming eggs 5 or more times/wk, compared with never/rare consumption, was 0.73 (0.60, 0.89).

                          I know you’re joking, but possible causal path here: People with Alzheimer’s lose ability to use stove -> eat simpler less involved breakfasts -> eats less eggs

                            You can make eggs in a microwave (critically so long as you don't do it in the shell)

                            • ajross · 4 days ago

                              You can, but people don't as a general rule. It's a traditional food prepared traditionally. And importantly, another thing early Alzheimers cases don't do is learn new cooking hacks.

                              • b3lvedere · 4 days ago

                                Works surprisingly good indeed. Just get a bowl, stir some eggs, add seasonings of choice and pop it in. Be sure to stop the microwave on time, because the mixture expands a lot.

                              They would forget where they put them.

                              Joking aside, (and I speak as someone who has lost 2 close members of my family to dementia), as soon as people start to experience any form of dementia, there is a sort of coping mechanism that kicks in where they stop doing “complex” things as much as they used to, because there is a huge amount of anxiety that is caused by losing short-term memory (you are constantly thrown into situations where you can’t make sense of what’s going on). So my mother-in-law for example, stopped cooking for herself long before some of the other symptoms really became apparent. She told everyone she was “bored of it”, and when cooking for a larger group she wolud constantly check and recheck the recipe. At the time it drove me crazy but then later when she was diagnosed with Alzheimer’s it all started to make sense.

                                    Agreed that seems like a potential conflict that should be scrutinized, but it highlights a real problem in health research. Who else would fund a 40,000 participant 15 year study about egg consumption and Alzheimer’s? How many studies are not conducted because no one is interested in funding them?

                                        Insurance companies don't fund medical research AFAIK? But if they did, it would be coming out of your premiums.

                                        The US Government is not a reliable source of research or funding these days.

                                        Universities are generally looking for subjects that will further their prestige and expand the frontiers as they understand them. This isn't that. And they, too, have funding issues, tracing in many ways right back to the government.

                                              Quality of this study aside, and n of 1 here, my own state of mind, clarity of thought, and sleep are all noticeably better when I'm eating 2 or 3 eggs a day, 3 to 5 days a week. (I might go 7 days, but an independent value placed on dietary variety prevents that--perhaps foolishly when I notice what I'm eating on off days instead of the eggs.)

                                              Regardless, this whole eggs-are-evil thing has probably done more to harm the health of Westerners than any other dietary advice, with the possible exception of the fat-is-evil nonsense.

                                                Do you think the eggs are causing the better sleep, or are you more likely to have the energy to make eggs in the morning if you’d had a good night’s sleep?

                                                  It seems the eggs improve the sleep, because after poor sleep, eggs the following day seem to have an effect on breaking the poor-sleep doom loop (which is: poor sleep elevates cortisol, adrenaline, heart rate, junk-food cravings, and the need for caffeine--all of which contribute to another night of bad sleep). Not sure if it's the choline, which eggs have a lot of, or the egg-generated satiety that helps prevent eating too much. I think it may be the choline because when I'm otherwise eating high-choline foods such as red meat, my sleep is also better.

                                                  Given that a great number of Westerns are overweight, it's probably appropriate for them to act as though "fat is evil" due to calorie density. Plus: saturated fat should be avoided; this is another thing Westerners are likely to be getting too much of.

The longer period between meals--snack-free--afforded by the bacon also means that post-meal insulin (the energy-storing hormone) has a chance to drop off, leaving glucagon (the energy-burning hormone) a path for liberating stored energy to power physical and mental activity.
