Full-fat Dairy Consumption Linked to Lower Dementia Risk: A 25-Year Study

Published December 18, 2025
What Happened?
A large, long-term study published in Neurology on December 17, 2025, suggests a correlation between higher consumption of full-fat cheese and cream and a reduced risk of developing dementia.Researchers followed over 27,000 adults in Sweden for approximately 25 years, tracking their dietary habits and dementia diagnoses.
Participants who consumed 50 grams or more of high-fat cheese daily exhibited a 13% lower risk of dementia compared to those consuming less then 15 grams. similarly, those consuming at least 20 grams of high-fat cream per day showed a 16% reduction in dementia risk.
Defining “High-Fat” Dairy
The study specifically focused on high-fat dairy products, defined as those containing over 20% fat. This includes popular cheeses like cheddar,Brie,and Gouda. High-fat creams typically contain 30-40% fat, encompassing whipping cream, double cream, and clotted cream. these are commonly labeled as “full-fat” or “regular” options in grocery stores.
Importantly, the study did not find a similar association with low-fat cheese, low-fat cream, milk, butter, or fermented milk products.
Study Methodology & Data
the research team analyzed data from 27,670 adults in Sweden, with an average starting age of 58. Participants were followed for roughly 25 years, during which 3,208 individuals received a dementia diagnosis.
Dietary intake was assessed through detailed food diaries covering one week, supplemented by questionnaires about long-term eating habits and discussions with researchers regarding food preparation methods.
| Dairy Product | Fat Content (approx.) | Impact on Dementia Risk (vs. lowest intake) |
|---|---|---|
| High-Fat Cheese (e.g.,Cheddar,Brie) | >20% | 13% lower risk (≥50g/day) |
| High-Fat Cream (e.g., Whipping Cream) | 30-40% | 16% lower risk (≥20g/day) |
| Low-Fat Cheese | <20% | No significant association |
| Low-Fat Cream | <20% | No significant association |
What Does this Mean?
This study doesn’t prove that eating high-fat dairy prevents dementia. It establishes an association, meaning there’s a statistical link between the two. the exact mechanisms behind this potential connection remain unclear and require further examination.
Possible explanations include:
- Fatty acids: Specific fatty acids found in full-fat dairy may have neuroprotective effects.
- Nutrient profile: Full-fat dairy contains essential nutrients like vitamin K2, which is linked to brain health.
- Gut microbiome: Dairy consumption can influence the gut microbiome, which is increasingly recognized for its role in brain function.
Who is Affected?
These findings are relevant to individuals concerned about dementia risk, particularly those who enjoy consuming full-fat dairy products. It challenges previous dietary recommendations that often emphasized low-fat options. However, it’s crucial to remember
