Dairy consumption linked to lower dementia risk in surprising new study

A large Swedish study suggests that some high-fat dairy foods are linked to a lower risk of dementia.

Researchers in Sweden used data from the Malmö Diet and Cancer cohort, which included 27,670 adults aged 45 to 73 in Malmö, Sweden.

The team then conducted interviews, collected food diaries, and asked the patients questionnaires to calculate how much of each dairy product people ate per day. They also separated dairy into high-fat and low-fat types. High-fat cheese was defined as more than 20% fat, and high-fat cream as more than 30% fat.

Participants joined the study between 1991 and 1996 and were followed for an average of 25 years afterward.

The main outcome they looked at was all-cause dementia, while Alzheimer’s disease (AD) and vascular dementia (VaD) were studied separately. Over the follow-up period, 3,208 people developed dementia. Within these groups, those who consumed high-fat cheese were significantly less likely to develop dementia.

“We were a bit surprised to see a lower dementia risk among people who ate more high-fat cheese,” Emily Sonestedt, associate professor of nutritional epidemiology at Lund University in Sweden, told Fox News Digital.

At the same time, she says it isn’t entirely unexpected to see a link with vascular dementia.

Most other dairy products, including low-fat cheese, low-fat cream, milk and fermented milk, showed no consistent association with overall dementia risk. (iStock)

“Many dementia cases involve damage to small blood vessels in the brain. Our own previous work, and several international studies, including from the US, have shown neutral or slightly protective associations between cheese and cardiovascular disease.”

The study adjusted for factors such as age, sex, education, smoking, physical activity, alcohol use, body mass index, hypertension, overall diet quality and other dairy products.

People who ate at least 50 grams per day of high-fat cheese had a lower risk of all-cause dementia compared with those eating less than 15 grams per day. They also had a lower risk of vascular dementia.

High-fat cream showed a similar pattern: people consuming at least 20 grams per day had a 16% lower risk for all-cause dementia compared with non-consumers.

Other dairy products did not show clear links with overall dementia risk. Low-fat cheese, low-fat cream, milk, fermented milk, and butter generally showed no association with all-cause dementia.

One exception was that high butter intake (at least 40 grams a day) was associated with a higher risk of Alzheimer’s disease. The study also found that high-fat cheese was linked to lower AD risk only among people who did not carry the APOE ε4 risk variant, a genetic variant linked to Alzheimer’s.

This was an observational study, so it cannot show cause and effect, and unmeasured factors may still play a role.

“The study was conducted in Sweden, where people mainly eat hard, fermented cheeses, so the results may not apply directly to countries with very different cheese types and eating patterns,” said Sonestedt.

Because the study was observational and diet was measured only once, the results should be interpreted cautiously and cannot be used to conclude that high-fat dairy prevents dementia. (iStock)

Diet was measured only once, so changes over time were not fully captured. Cream intake was measured with less precision than cheese.

“Although we adjusted for many lifestyle and health factors, it is still difficult to say that the cheese itself is protective. It is more likely part of a broader eating pattern and lifestyle that may support long-term brain health,” researchers noted.

Dementia diagnoses after 2014 were not validated in detail, and baseline cognitive status was not available.

Some dementia cases may have been missed, and the results are from a Swedish population, which may limit generalization.

The findings were published in Neurology, the medical journal of the American Academy of Neurology.

Family pleads for kidney donor as teen’s health declines: ‘We need help’

Family pleads for kidney donor as teen’s health declines: ‘We need help’

NEWYou can now listen to Fox News articles!

A New Jersey family is desperately seeking a living donor to save Thaddeus Giansanti, an eighth-grader who was born with kidney disease. 

Thaddeus has had multiple surgeries throughout his 13 years, including one to remove a kidney as a baby.

Despite his struggles, he has remained positive and optimistic, his parents shared with Fox News Digital.

“His remaining kidney is now failing,” said his father, Carlo Giansanti. “We are not a match, so now we’re asking for help from the community.”

The family first found out about their son’s kidney disease before he was born, when an ultrasound detected a potential issue.

“It was nothing alarming at that point — it looked like he had extra fluid when he was born,” Thaddeus’ mother, Christa DeMark, told Fox News Digital. “Everything seemed normal, but right before we were leaving, they noticed an elevated creatinine number (a measure of kidney function in blood tests) that led to us being in touch with nephrology.”

She added, “There was something wrong with the ureters (tubes that carry urine from the kidneys to the bladder) and the formation of the kidneys.”

SURGEONS KEEP MAN ALIVE WITHOUT LUNGS, PAVING NEW PATH TO TRANSPLANT

Thaddeus spent an extended period of time in the NICU, where he had multiple procedures. Before he was even 5 months old, he underwent a left nephrectomy to remove his left kidney. 

His remaining kidney was diagnosed with chronic kidney disease, which has required lifelong medications.

“He’s been with nephrology and nephrologists his entire life, and up until last year, everything’s been stable, but that’s been slowly changing,” DeMark said. “He’s getting bigger, and it’s been putting more stress on his remaining kidney.”

Doctors informed the family that their best course of action would be to find a living donor.

“Everything’s been sped up based on his bloodwork lately,” DeMark said. “So it’s looking like we need something quicker than we thought, which is why we’re looking for living donors.”

“It has pushed us to rely on faith in a way that’s very palpable — we are just coming together as a family and taking each day as it comes.”

If Thaddeus does not receive a kidney transplant within a couple of weeks, he will need to be put on dialysis, according to his doctors.

“It’s obviously been challenging for him,” DeMark said. “He’s dealing with it very well, but these are difficult situations we’re navigating.”

His parents describe Thaddeus as a smart, outgoing boy — a straight-A student who was recently awarded multiple scholarships for next year, when he will become a high-school freshman.

Thaddeus is very athletic and enjoys playing soccer, golfing and fencing. He also plays piano and often volunteers in his community, including being an altar server and working with the local food pantry.

“He loves his family, and loves doing things with his family,” DeMark said. “He’s just a great kid.”

Thaddeus’ parents said they have not shared much about their son’s medical condition until now. “We wanted Thad to just be the bright, happy person that he is, so we’ve minimized it for years,” DeMark said. 

But in the last couple of weeks, as their son’s condition has become more dire, they have started to speak out about their situation.

“We never expected to have such an outpouring of people who cared or people trying to help — it’s been incredibly humbling,” DeMark said.

“It has pushed us to rely on faith in a way that’s very palpable — we are just coming together as a family and taking each day as it comes,” she went on. “We are remaining hopeful because we know there’s a solution to this problem. We just need help.”

“The miracle Thad needs right now is people who have the ability to step up,” his mother said. “He is a great kid, a kind kid.” (Christa DeMark)

To be considered for the donation program, kidney donors must be 45 or younger, have a BMI under 30 and match Thaddeus’ O blood type.

For those who are considering becoming donors, DeMark emphasized that it entails a laparoscopic procedure with a “fairly quick” healing process that is covered by their insurance, not the donor’s.
