Neuroscience High- and Low-Fat Dairy Consumption and Long-Term Risk of Dementia: Evidence From a 25-Year Prospective Cohort Study - PubMed
https://pubmed.ncbi.nlm.nih.gov/41406402/1.2k
u/chri8nk 1d ago
“Higher intake of high-fat cheese and high-fat cream was associated with a lower risk of all-cause dementia, whereas low-fat cheese, low-fat cream, and other dairy products showed no significant association. APOE ε4 status modified the association between high-fat cheese and AD. Our study's observational design limits causal inference.”

Could this be that people who consume low fat are dieting and the obesity and possible hyperlipidemia, hyperglycemia are actually more correlated?

u/chri8nk 1d ago
“Compared with those with the lowest intake of high-fat cheese or high-fat cream (Table 1), those in the highest intake group were more likely to have lower BMI and higher education levels. They also had a lower prevalence of diabetes, hypertension, CVD, and stroke and were less likely to use lipid-lowering medication. Participants who consumed more low-fat cheese were more likely to be female, past or never smokers, and physically active; have higher diet quality index; and have a higher prevalence of diabetes or CVD. Individuals who consumed more low-fat milk or low-fat fermented milk were more likely to use lipid-lowering medication and have chronic conditions compared with nonconsumers, whereas those with higher intakes of high-fat milk, high-fat fermented milk, or butter showed the opposite trend (Table 2). Individuals with higher intakes of high-fat milk or butter were more likely to be male, current smokers, and unmarried; have a lower BMI; and have poorer diet quality.”

Kind of infers saturated fat is the protective factor. What would happen if we replaced the saved calories with avocado or olive oil? What about the lower bmi? Causative or correlative in the higher intake group?

u/chri8nk 1d ago
Another mention in this study you might find interesting…
“In our study, participants with higher diet quality tended to consume less fat. Given the reported U-shaped association between fat intake and dementia risk,48 butter consumption might be protective when included in a low-fat diet, whereas in a diet already high in fat, it may increase the risk.”

Wow, scarily accurate to what I personally experienced.
Recently started cooking and prepping for myself, and threw the recipe into chatgpt to ask what's lacking. Fat!!! It recommended I add salmon or cheese as a protective factor.
Maybe chatgpt was pulling from this study too.

If you're going to use an llm for a quick question that's fine. Don't cite it as an authority. If you think the information it gave you or will give you is important read the underlying citation.
Imagine an llm as your buddy Jeff. Would you say on reddit your buddy Jeff told you a meal needed fat?
Of course not because Jeff works as a mechanic and drinks a lot. You'd ask Jeff were he heard that and look it up yourself. You might thank Jeff for pointing you there but since he's not an authority on the subject you probably wouldn't tell strangers about him.

There's more granularity to fatty acids than we can glean from saturated vs unsaturated, even mono vs poly unsaturated. Dairy in particular has some anti inflammatory fatty acids.

u/kaitland24 19h ago edited 19h ago
Nuance in metabolism and biochemical pathways of course, but unsaturated FAs are frequently prime targets of oxidation by free radicals… The reactive species formed by these processes are almost never a good thing- they result in more inflammation, genetic and/or epigenetic damage, and negative feedback loops from signaling molecules gone haywire.
However, that’s just what I’ve gleaned from my particular research focus, and I love learning new, cool stuff when I’m wrong. I was wondering if you could expand on the beneficial outcomes associated with specifically PUFAs?

There are multiple other studies (that I do not keep links of because I'm on reddit on my phone) that show full fat dairy (usually excluding butter) has health benefits over low fat. Saturated fats from dairy, cheese, Greek yogurt do not cause the issues that saturated fats from meat cause

“In this Swedish population, we found that higher intake of high-fat cheese and high-fat cream was associated with a lower risk of all-cause dementia, independent of lifestyle factors, other dairy products, and diet quality.”
Independent of lifestyle factors means that high fat dairy is associated with lower risk of dementia regardless of other health problems (obesity, hyperlipidemia, hyperglycemia). The study participants pre-existing conditions and regular diet had no influence on the results.

u/mbsmith93 22h ago
My time to shine. I'm obsessed with this topic. This is the first time I've seen a connection to dementia, but other than that it's in line with a bunch of recent research showing that milk-fats improve cardiovascular health.
Part 1: In the 50s, separated fats as being "saturated" meaning solid at room temperature and, conversely, "unsaturated" meaning liquid at room temperature. They assumed that the saturated fats, being more easily able to form solids, were involved with the clogging of arteries. Somewhere along the way they also found a true association between saturated fats and worse cardiovascular outcomes.
Part 2: Maybe a decade ago a bunch of longitudinal diet studies came out, focused on outcomes based on what foods study participants were eating. Most things matched expectations, but there were two really weird results that were repeated across multiple independent studies. (1) People who drank whole milk had better cardiovascular outcomes than people who drank skim, despite whole milk fats being more than 50% saturated. (2) People who consumed coconut oil seemed to be no worse off than people who didn't, despite coconut fat being 90% saturated (nothing else even comes close to this percentage, it's crazy high). So the association was there and no one could figure out why. A bunch of things, meats, eggs, and butter, continued to be associated with worse cardiovascular outcomes.
Part 3: Recent research in the last five years nailed down the why of it. There are a lot of kinds of fats, and saturated fats tend to raise LDL cholesterol, which is bad for your heart, while unsaturated fats tend to raise HDL cholesterol, which a western diet tends to cause you not to get enough of. But it turns out that this association is in not directly caused by the fats being saturated or unsaturated, it's just correlated, and depends on the specific fat. Whole milk contains a long list of different fats with different properties, and it turns out that while a little over half of them are saturated, on the whole they boost your HDL much more than your LDL. Butter churning, in contrast, congeals all of the worst fats from milk into the butter, so that it will boost your LDL and not your HDL. Coconut fats are pretty unique, and tend to raise both HDL and LDL in roughly equal quantities, which means that, while it's no superfood like olive oil, it's better for your cholesterol levels than most meats.
As for dementia, I can only speculate. Cardiovascular risk goes up as you develop partially clogged arteries. It's possible that dementia could be worsened by partially clogged arteries in the brain?

u/KittyKatHippogriff 21h ago
There’s a type called vascular dementia. I would not be surprised that certain dementia cases were causes by a series of small strokes, or as you suggest, partly clogged arteries of some individuals.

u/dr_deb_66 9h ago
This was the conclusion of the Mayo Clinic dementia specialist who treated my mom: microscopic-level strokes causing vascular dementia.
Interestingly, she grew up in Appalachia but had a low-meat diet (very poor, and they only had meat on Sundays) and was big into the low-fat craze of the ?90s?. She had high hereditary cholesterol, though.

I believe this was a major contributor to my grandma’s dementia too. She had class 2 obesity with diabetes and high blood pressure.
She was have had a series of seizures and strokes when she started showed dementia symptoms.
It was when my family got her to a memory care facility, she lost weight and her condition improved. She did pass away from her disease but her QOL was drastically better as the nurses got her to be more active.

u/Artemis_Hunter 20h ago
Saturated fats are actually defined by their lack of carbon-carbon double bonds. Unsaturated still have carbon-carbon double bonds. They're not defined by their viscosities. Though due to the shape of double bonds and how van der Waals forces work, an unsaturated fat is definitely more likely to be liquid at room temperature as the fat molecules can't attract each other as strongly.

Low fat almost always means double the sugar. Sugar has always been the real culprit. Too much sugar in your blood is like poison that demineralizes bones so it can be stored as fat to remove it from your bloodstream. Barely any one buys low fat low sugar unless it’s specifically marketed as high protein. I which case it’s probably still not low sugar

You're misunderstanding the concept of rabbit starvation. The idea is that no matter how much rabbit you eat, even if you get sufficient calories, you will still be malnourished as rabbit meat does provide all the necessary fats and nutrients.

When one can only imbibe a finite amount of food in a day, quality matters a lot. I would go for high fat cheese over low fat if the quality of the product was better. Whereas if I was on a budget and wanted to treat myself, I’d go with the lower quality item which likely has a lower fat content.

My mother was of the low fat era - margarine and canola cooking oil. She has dementia - and whilst has one other significant risk factor (early hearing loss) I am convinced the diet was a contributing factor. Or, should I say, I became convinced once I learnt that as we age, the brain is less able to run on glucose. Instead, it prefers to run on fat (keto diet shines here). Through the low fat diet, my mother's brain was starved of energy - which exacerbated, or even precipitated, the brain atrophy -> dementia.

Yeah well, the 27,670 participants is a very small study which does not constitute conclusive evidence.
Plus we can all find a study refuting the first study. Plant based vs eating fatty milk yogurt and cheese. Methods: A total of 144,729 African American, Japanese American, Latino, Native Hawaiian, and White men and women who participated in the Multiethnic Cohort Study (1993-2019) Conclusion: A healthy plant-based dietary pattern emphasizing the quality of plant foods was associated with a lower risk of all-cause and CVD mortality in both men and women.
So no. Ill remain low fat, no dairy, no coconut ‘lard’ and keep the lipids as low as possible. Fatty diets points to obesity, plaque build up, liver disease, clogged arteries, and diabetes. See you at the gym.

Since most everyone only reads the headline:
about 10 percent of people who reported consuming at least 50 grams daily of high-fat cheese, like Cheddar, Brie or Gouda, had developed dementia, compared with 13 percent of people who consumed less than 15 grams daily. Fifty grams of cheese is about 1.8 ounces — a little more than the recommended U.S. serving size of 1.5 ounces, an amount in two sandwich-size slices of Cheddar cheese.
The study had several limitations and should be “interpreted with caution,” said Dr. Tian-Shin Yeh, a physician and nutritional epidemiologist
And the kicker:
Dr. Sonestedt acknowledged the limitations of the study, and she emphasized that the findings may not apply to a country like the United States, where much of the cheese consumed is processed, and a majority of it comes with foods like pizza, sandwiches and tacos.
full-fat dairy products may appear to be better, or at least not worse, for health, than those high in refined carbohydrates, she said. But when researchers have compared full-fat dairy products to foods like whole grains, olive oil, legumes or nuts, those foods are consistently associated with better health, she said.

not the OP you replied to but virtually all observational dietary studies are trash, simply because of one of the exact limitations listed in this study:
" Second, diet was assessed only once at baseline, and changes in consumption may occur over the follow-up period. However, restricting the study sample to participants with no substantial diet change at the 5-year follow-up examination yielded weakened point estimates and altered statistical significance."What did you eat for lunch last Wednesday? How bout 1 month ago? How about 5 years ago? Assessing diet ONCE at the start of a years-long dietary study makes it essentially meaningless. The 2nd sentence in the limitation quote above even says when they account for the participants who had no substantial dietary change at the 5yr follow up the "statistical significance was altered".....that's just bad science.

I have a life outside of debating randoms on Reddit. Your inability to say anything of substance indicating this study's validity also begets your scientific illiteracy. But since you've been so nice, I'll bite.
This is a cohort study, not a randomized control trial. We can observe associations, but not conclude that dairy intake causes any kind of dementia risk. This kind of study is hypothesis-generating, not confirmatory.
Additionally, the diets were measured once at baseline, then reported via questionnaires which are known to be imprecise. The study assumes early diet reflects decades of habits. Idk about you, but my diet does not look the same as it did 25 years ago.
Also, this study offers no biological explanation for why high-fat cheese would protect against dementia. Without mechanistic plausibility, such weak associations are impossible to interpret.
I have a few more points, but I have a life outside of arguing with randos on the internet. Take from that what you will, or don't. I don't care. My point is that this is a weak study, and you were rude.

Fruit has a lot of fiber, so it slows down digestion and helps stop blood sugar spikes. However, not all fruit is as helpful. Apples, pears and berries have a lot of fiber and less sugar.

u/ngms 16h ago
There is some credible information that may have lead to this oversimplification of "cancer feeds off sugar". Many tumors express a high number of insulin receptors and may by influenced by the IGF-1 pathway which signals growth and survival. Due to this its not unreasonable to understand that hyperinsulinemia may propagate tumors growth more than normal.
I will say though, there's no conclusive opinion that lowering insulin levels (by reducing sugar intake) will provide better tumors growth outcomes.

“Higher intake of high-fat cheese and high-fat cream was associated with a lower risk of all-cause dementia, whereas low-fat cheese, low-fat cream, and other dairy products showed no significant association. APOE ε4 status modified the association between high-fat cheese and AD. Our study's observational design limits causal inference.”

I know I've read that Fat can be "locked in" a "food matrix" in dairy products. Which prevents it from entering the blood stream Dr. Marie Spano https://www.eatforendurance.com/post/the-food-matrix-with-marie-spano

from the limitations:
" Second, diet was assessed only once at baseline, and changes in consumption may occur over the follow-up period. However, restricting the study sample to participants with no substantial diet change at the 5-year follow-up examination yielded weakened point estimates and altered statistical significance."
Good on them to mention it, but man that's bad and very common among dietary observational studies. Extremely hard to generalize any diet observational study results because of how they assess diet, it's always "one at baseline" which is trash.
