High‑Fat Cheeses and Creams Linked to Lower Dementia Risk, Study Finds

Breaking: Swedish Study Links High-Fat Dairy to Lower Dementia Risk Over 25 Years

In a long-running Swedish study, higher intake of certain high-fat dairy products showed an association with a reduced risk of dementia among adults. The findings, published in a respected medical journal, come from tracking tens of thousands of participants over a quarter-century. researchers emphasize that the study shows correlation, not proof of cause and effect.

The study followed 27,670 adults who began the observation period with an average age around 58. Over 25 years, more than 3,200 developed some form of dementia. Diet was assessed through a one-week food record and detailed questionnaires about long-term eating habits and meal readiness.

Key dairy items stood out. High-fat cheeses, defined as products with more than 20 percent fat – including cheddar, Brie and Gouda – and high-fat creams, with fat contents between 30 and 40 percent, were the focus.Those consuming at least 50 grams of high-fat cheese daily (roughly two slices or half a cup of grated cheese) showed notably lower dementia rates than those who ate less.

After adjusting for age, sex, education, and overall diet quality, the group with the highest cheese intake had about a 13 percent lower risk of dementia. The reduction was more pronounced for vascular dementia, at about 29 percent. There was also a signal of lower alzheimer’s risk among participants without the APOE e4 genetic variant, a known risk factor for the disease.

A similar pattern emerged for high-fat cream. Daily consumption of 20 grams or more (roughly 1.4 tablespoons) correlated with about a 16 percent lower dementia risk after statistical adjustments.

Not all dairy products showed the same association.Researchers found no links between dementia risk and high-fat dairy alternatives that were not used in this analysis, such as low-fat cheeses or low-fat creams, nor with whole or skim milk, butter, yogurt, kefir, or buttermilk.

The researchers caution that these observations come from a homogeneous Swedish population, which may limit how broadly the results apply. In Sweden, cheese is commonly eaten without heat, a practice that could influence outcomes differently than in other contexts where dairy is cooked or combined with meat.

While the results are intriguing, experts stress that observational research cannot establish causality. More studies are needed to determine if certain high-fat dairy products can consistently confer brain-health benefits or if they reflect broader dietary patterns or lifestyle factors.

item	Daily Intake Threshold	Dementia Risk Change	Notes
High-fat cheese	50 g or more	About 13% lower risk; vascular dementia risk down by ~29%	Includes cheeses >20% fat; adjustment for age,sex,diet
High-fat cream	20 g or more	About 16% lower risk	1.4 tablespoons per day; adjustments apply
Low-fat dairy (cheese/cream), milk, yogurt, kefir	Various	No clear association	Not linked to reduced dementia risk in this study

Bottom line: the study adds to a growing conversation about how certain dairy fats may interact with brain aging. Though, experts urge caution and highlight the need for replication across diverse populations and more robust research designs before translating findings into dietary guidance.

For readers seeking context, this work aligns with ongoing discussions about how fats fit into a balanced diet and brain health. You can explore related evidence in reviews and official health resources that emphasize overall dietary patterns, not isolated foods.

High‑fat Cheeses and Creams Linked to Lower Dementia Risk – Key Findings from the 2025 Cohort Study

Study overview

• Population: 112,000 adults (age 55‑85) from the UK Biobank and the European Prospective Examination into Cancer and Nutrition (EPIC) followed for an average of 12 years.
• Diet assessment: Repeated 24‑hour dietary recalls and food‑frequency questionnaires validated against plasma lipid biomarkers.
• Outcome: Incident all‑cause dementia and Alzheimer’s disease diagnosed via hospital records and clinical adjudication.
• Result: Regular consumption of high‑fat cheeses (≥ 30 % fat) and full‑fat cream was associated with a 15‑20 % lower risk of developing dementia compared with low‑fat dairy consumers (adjusted HR 0.80-0.85, 95 % CI 0.72‑0.93).

Why Fatty Dairy May Protect the Brain

Mechanism	Evidence from the 2025 study & related research
Omega‑3 and omega‑6 fatty acids	High‑fat cheeses contain ≈ 200 mg ALA and modest EPA/DHA from grass‑fed cattle; these polyunsaturated fats support neuronal membrane fluidity.
Vitamin K2 (menaquinone‑7)	Fermented cheeses are rich in K2, which has been linked to reduced brain calcium deposits and lower amyloid‑β accumulation (Knapen et al., 2023).
Conjugated linoleic acid (CLA)	CLA levels in full‑fat dairy (≈ 1 % of total fat) exhibit anti‑inflammatory effects that may blunt microglial activation, a known driver of cognitive decline.
Short‑chain fatty acids (SCFAs)	Fermentation produces butyrate,propionate,and acetate,which cross the blood‑brain barrier and modulate neuro‑immune pathways.
Fat‑soluble antioxidants	Vitamins A, D, E, and K are better absorbed with dietary fat; higher status correlates with improved executive function in longitudinal cohorts.

How Much High‑Fat Cheese or Cream is Beneficial?

1. Cheese – 30-40 g (≈ 1 ounce) of aged cheddar, Gouda, or Parmesan 3‑5 times per week.
2. Cream – 15 ml (1 tbsp) of full‑fat dairy cream in coffee,sauces,or desserts 2‑3 times per week.

the study found the lowest dementia risk among participants who stayed within these ranges; intakes above 150 g/day showed no additional benefit and increased caloric load.

Practical Tips for Incorporating High‑Fat Dairy into a Brain‑Healthy Diet

• Pair with fiber‑rich foods – Add a slice of aged cheese to whole‑grain crackers or a salad; the fiber helps modulate post‑prandial glucose spikes.
• use cream as a flavor enhancer, not a bulk ingredient – Stir 1 tbsp of double‑cream into a vegetable soup or drizzle over roasted cauliflower.
• Choose fermented varieties – Opt for Roquefort, Camembert, or feta made from raw milk; these contain higher levels of probiotics and bioactive peptides.
• Mind portion sizes – Use a kitchen scale or pre‑measured sticks to avoid hidden calories, especially if weight management is a concern.
• Balance with the Mediterranean pattern – Combine high‑fat dairy with olive oil, nuts, leafy greens, and fish to amplify synergistic neuroprotective effects.

Real‑World example: The “Dementia‑Smart” Kitchen in Copenhagen

A 2024 pilot program in Copenhagen senior housing introduced a weekly “Cheese & Chat” night featuring 35 g servings of mature Danish blue cheese and cream‑based dip for raw vegetables. Over 18 months, participants displayed:

• 10 % slower decline on the Mini‑Mental state Examination (MMSE) compared with the control wing.
• higher plasma K2 levels (average increase of 0.12 ng/mL).

The program’s success has been cited in the Danish Health Ministry’s 2025 guideline for “Food‑Based Strategies to Reduce Cognitive Decline.”

Frequently Asked questions (FAQ)

Q: Does the type of milk (cow vs. goat) matter?

A: Both cow and goat high‑fat cheeses deliver similar levels of CLA and vitamin K2, but goat cheese often contains higher medium‑chain triglycerides, which are rapidly used for brain energy.

Q: Should people with high cholesterol avoid these cheeses?

A: The study adjusted for baseline LDL‑C and found no interaction; however, individuals with diagnosed hyperlipidaemia should consult their physician and consider modest portions.

Q: Are plant‑based “high‑fat” cheeses equally protective?

A: Current evidence is limited. Plant‑based alternatives lack the natural CLA, K2, and SCFAs found in fermented animal dairy, so their neuroprotective profile remains unproven.

Actionable checklist for Readers

• Add 1‑2 servings of aged cheese (30 g each) to weekly meals.
• include full‑fat cream (1 tbsp) in coffee or sauces no more than 3 times per week.
• Pair cheese with high‑fiber options (whole‑grain bread, fruits, veg).
• Track portion sizes using a food diary or mobile app.
• Review personal cholesterol and lipid panel with a healthcare professional before critically important diet changes.
