The vegetable lobby has had a good run. For decades, the conventional wisdom on brain health has been some variation of the same tired sermon: eat less meat, eat more plants, and maybe your aging mind will hold together long enough to remember where you parked the car.

A new study out of Sweden suggests that for roughly a quarter of the American population, that advice has been wrong — measurably, consistently, damagingly wrong.

Life is exhausting. Depletion is something else. And only one of them is fixed by a rib-eye.

Published in JAMA Network Open, the study tracked more than 2,000 Swedish adults over 60 for 15 years. Among carriers of the APOE4 gene — the strongest genetic risk factor for Alzheimer’s disease — those who ate the most meat showed slower cognitive decline and lower dementia risk than those who ate the least.

Among the those who ate the most meat, the elevated dementia risk associated with carrying APOE4 disappeared entirely.

The most feared dementia gene in medicine — at least in this cohort — effectively disarmed by the food that built the brain carrying it.

Brain drain

One in four Americans carries at least one copy of APOE4. Two-thirds of people with Alzheimer’s carry it. This is a massive slice of the country.

Tens of millions of Americans have been dutifully following brain-health guidelines that may be contributing to the very decline those guidelines promised to prevent.

This is what happens when nutritional science gets hijacked by ideology and the bill comes due 30 years later.

APOE4 appears to influence how efficiently the body absorbs and uses certain nutrients, particularly vitamin B12 — essential for nerve function and found almost exclusively in animal products. APOE4 carriers who ate more meat showed measurably higher B12 levels in their blood.

The gene also affects how the body processes fats and cholesterol — the building blocks brain cells require for fuel and structure. APOE4 is the oldest variant of the gene, one that likely predates agriculture entirely. Some bodies, it turns out, never got the memo about kale smoothies and the moral purity of eating like a rabbit.

Steakholders

None of this will surprise anyone who has eaten a quality steak and felt, within the hour, unreasonably capable.

That sudden clarity. The alertness. The faint, irrational optimism about existence — that’s iron talking. Heme iron, specifically, found in red meat and absorbed at rates far higher than the iron in spinach and lentils, which the body processes with all the urgency of a man skimming terms and conditions.

Roughly 40% of American women are iron-deficient. A significant portion of the population moves through daily life in a low-grade fog of fatigue and poor concentration they have simply come to accept.

Life is exhausting. Depletion is something else. And only one of them is fixed by a rib-eye.

Iron dome

The dietary culture most likely to produce iron deficiency is the same one celebrated as virtuous. Plant-based iron comes pre-sabotaged. Phytic acid in grains and legumes — the foods canonized by clean eating — actively blocks absorption before it reaches the bloodstream.

The demonization of red meat has been so thorough, so relentless, and so institutionally backed that an entire generation grew up believing a burger was more dangerous than a cigarette.

This was not an accident.

Decades of dietary guidelines, food pyramid revisions, and industry-funded nutrition research pushed animal products to the margins of the respectable plate, while carbohydrates and seed oils quietly took the center.

Early-onset dementia is rising in people who should be nowhere near it — men and women in their 30s and 40s, the first generations raised under the full weight of anti-meat orthodoxy.

Nipped in the bud

Meanwhile, more parents are raising children on exclusively plant-based diets, motivated by love and a sincere belief that they are doing right by their kids. The research on what chronic iron deficiency, B12 absence, and inadequate animal protein does to a developing brain is not something the wellness industry tends to advertise. In several studies, it reads less like a dietary choice and more like an uncontrolled experiment conducted on people too young to consent.

Meat consumption has been falling for years. Alzheimer’s rates have been climbing for years.

No one in an official capacity has connected those dots — which is itself worth noting.

The Swedish study does draw one important line. Processed meats showed no protective benefit and were linked to higher dementia risk regardless of genetics.

Bacon, sausages, deli meats, the sweating cylinders of mystery protein rotating slowly at the gas-station counter — these are not the argument.

Fresh red meat and poultry, unprocessed and cooked with basic competence, are what drove the cognitive benefit.

Carnivores settled continents, built civilizations, and mapped the known world. Every civilization that ever amounted to anything ate meat.

The ones that didn’t aren’t around to argue the point.

A 19-year-old Texas male reportedly violated bond at least a half dozen times before being accused of murder — while he was out on probation.

In June 2024, Johnnie Lillie was sentenced to probation for burglary of a motor vehicle, KRIV-TV reported.

‘All you had to do on one occasion was either revoke his probation or revoke his bond. That would’ve taken him out of being in the community.’

“While he’s on probation, he picks up a possession of a prohibited weapon [charge], a machine gun. That’s pretty serious,” Andy Kahan with Crime Stoppers told the station.

KRIV reported that instead of revoking Lillie’s probation and sending him to jail, he was granted bond.

Then while free on that bond, Lillie was charged with another burglary of a motor vehicle, the station said.

“Now he’s out on not one, but two bonds, and is still on probation,” Kahan explained to KRIV.

Citing court documents, the station said Lillie violated his bond at least half a dozen times.

Then came Sept. 22, 2025 — the date when Lillie allegedly shot and killed 29-year-old Jermarkus Johnson, KRIV reported.

Harris County Sheriff Ed Gonzalez said on that date deputies learned a gunshot victim had been transported to a hospital by private vehicle.

The victim, identified as Johnson, was pronounced dead at the hospital, the sheriff said.

Detectives learned the shooting stemmed from an altercation during a dice game, Gonzalez said, adding that homicide detectives identified and charged Lillie for allegedly shooting Johnson.

Lillie was arrested on Oct. 1 at the courthouse when he appeared for an unrelated charge, the sheriff said, adding that Lillie was booked into the Harris County Jail.

According to Harris County Jail records, Lillie is charged with murder and unlawful possession of a weapon. His bond for the murder charge is $250,000; his bond for the unlawful possession of a weapon charge is $60,000. His next court date is scheduled for April 23. Blaze News on Friday confirmed with the jail that Lillie remains incarcerated.

KRIV said Lillie was under the supervision of both the probation department and pretrial services “but that didn’t stop him from allegedly committing murder.”

Kahan added to the station that “pretrial services says we cannot monitor him, he’s not abiding by any of his conditions. And again, he’s allowed to remain on probation and multiple bonds.”

KRIV concluded that “Lillie is one of many defendants who violate conditions of probation and bond, but nothing happens to them. Still taxpayers fork over money for two entities to supervise and report violations.”

Kahan added to the station that “all you had to do on one occasion was either revoke his probation or revoke his bond. That would’ve taken him out of being in the community. It would have had him locked up, and Jermarkus Johnson would be alive today.”
