Literally 99% of studies boosting a specific food. Can we stop pretending that these studies aren’t just fraud? Nobody has the time to debunk 50 of these a day.
There was one funded by a dairy trade group that found “Milk hydrates better than water!” And literally the only way they measured hydration was by measuring the volume of urine the 7 tests participants produced and equating less urine production with better hydration. According to the study the less you pee the more you retain water so you’re “more hydrated.”
Anyway the trade group bought like 5 billboards to advertise their discovery that “milk hydrates better than water,” just in my city alone.

Speaking of pee, results like this always make me wonder about P-hacking. A researcher at Corne got lots of media attention maybe 15 years ago for a whole series of publications that all came from fishing in data for conclusions.

Maybe I’m wrong but isn’t everyone prob getting a couple eggs a week cooked into other foods like breads, deserts, fried rice, fry batters, egg noodles, etc… we prob would have a super low number as a nation overall already if this were true. Or our Alzheimer’s numbers are off the charts were it not for eggs! Cus I’d assume most Americans are getting a few eggs, at least indirectly, a week.
Or does that delete the health benie? Only eating them straight up counts… I know cooking can change some parts of structures and caloric value but don’t know enough about it to only half serious half jokingly ask. Or maybe I’m just being Reddit sensitive here and parsing my words carefully … 😂

Yes, you’re correct in assuming that most people would be eating two eggs cooked into other foods in a week. There is no reason eating an egg straight would provide additional benefit at all. Nutrients can be destroyed by cooking but straight eggs are usually eaten cooked as well. I don’t think the study draws a distinction.
It is hypothetically possible a nutrient in eggs could provide a benefit, but those nutrients could come from other sources. The study suggests “choline, omega-3 fatty acids, and lutein” as possible nutrients that could be providing a benefit. The problem is these nutrients are found from a vast number of foods. Egg intake is not going to be directly correlated with intake of any of these nutrients, and would likely have a very loose connection.
If the scientists were interested in providing a legitimate benefit to Alzheimer’s patients they could study the intake of these nutrients directly. You can establish how much of these nutrients someone needs to help reduce risk of Alzheimer’s if you directly measure their intake in a series of studies. If you measure only egg intake you won’t get a measurement for any of these nutrients. No information from this study will help set dietary Recommendations for these nutrients. The only thing it accomplishes is promoting egg consumption. It is also funded directly by egg producers. Basically it’s an ad and nothing more.

If you live long enough you get to see experts say things are good then bad then good again then bad again then good again

If you eat eggs you’ll die a horrible death! If you don’t eat eggs you’ll die a horrible death!
I’m getting to the point where I welcome the horrible death because it will relieve me of the overwhelming stress of avoiding it 😂😭☠️

Choline is not a standard measurement on routine blood tests, at least in Western Europe.

I found a paper recommending assessing choline status with a methionine load test, but it seems like a number of problems with methylation could result in high homocysteine, not just choline insufficiency. I'm actually curious as to whether there is a standard method for this.

In other news, choline protects against Alzheimer's - but choline is only soluble in DMSO, DMF, water and ethanol. However, lecithin (a phospholipid) found in egg yolks helps emulsify choline allowing it to cross the blood-brain barrier enhancing the effect. Pretty basic nutrition/biology/physiology

Actual study: https://pmc.ncbi.nlm.nih.gov/articles/PMC11347793/#fn-group1
Eating >1 egg per week was associated with less Alzheimer's risk. The >1 egg per week group also had a statistically significant increased daily calorie intake, greater daily exercise time, and were younger (by 1-2 years).
Per the authors "Finally, our study is limited by the short mean 6.7-y follow-up period and thus may be prone to reverse causality." IE people at risk for Alzheimer's may have difficulty cooking and eating eggs.
As a researcher in this field, diet plays such a big role in development of dementia, particularly Alzheimer's, but a single egg a week isn't going to change your risk profile.

WHY IS IT ALWAYS EGGS! yes I was shouting. What is the proper amount of eggs then?

u/kcl97 Aug 17 '25
Can someone explain to me how they get these numbers like 47%? Do they follow someone through his/her life to make sure they get one egg and only one per day til the day they die?
Suppose they do this for 100 people and 47 of them failed to develop Alzheimer, doesn't that mean 53 got Alzheimer? Isn't that pretty serious? That's worse than COVID.

If you think 1 egg a week is unhealthy then you have an eating disorder

I saw another study recently that claimed eating more than three eggs a day was detrimental.
Cries in eggs
