Studies Suggest Red Meat May Help Prevent Alzheimer’s
At least for people who carry the APOE4 genetic variant, a juicy steak could keep the brain healthy.

Must even steak be politicised? The American Heart Association recently recommended eating more “plant-based” protein in a move to counter the Health and Human Services Department’s new guidelines calling for more red meat.
Few would argue that eating a Big Mac a day is good for you.
On the other hand, growing evidence, including a study last month in the Journal of the American Medical Association, suggests that eating more meat—particularly unprocessed red meat—can reduce the risk of Alzheimer’s in the quarter or so of people with a particular genetic predisposition.
The APOE4 gene variant is one of the biggest risk factors for Alzheimer’s.
You inherit one copy of the APOE gene from each parent. The most common variant is APOE3; the least is APOE2.
The latter carries a lower risk of Alzheimer’s, while the former is neutral. A quarter of people carry one copy of the APOE4 variant, and about 2% carry two.
APOE4 is more common among people with Northern European and African ancestry. In Europe the variant increases with latitude, and is present in as many as 27% of people in northern countries versus 4% in southern ones. God smiled on the Italians and Greeks.
For unknown reasons, the APOE4 variant increases the risk of Alzheimer’s far more for women than men.
Women’s risk multiplies roughly fourfold if they have one copy and tenfold if they have two. Men with a single copy show little if any higher risk, while those with two face four times the risk.
What makes APOE4 so pernicious? Scientists don’t know exactly, but the variant is also associated with higher cholesterol levels—even among thin people who eat healthily.
Scientists have found that cholesterol builds up in brain cells of APOE4 carriers, which can disrupt communications between neurons and generate amyloid plaque, an Alzheimer’s hallmark.
The Heart Association’s recommendation to eat less red meat may be sound advice for people with high cholesterol caused by indulgent diets.
But a diet high in red meat may be better for the brains of APOE4 carriers.
In the JAMA study, researchers at Sweden’s Karolinska Institute examined how diet, particularly meat consumption, affects dementia risk among seniors with the different APOE variants.
Higher consumption of meat, especially unprocessed red meat, was associated with significantly lower dementia risk for APOE4 carriers.
APOE4 carriers who consumed the most meat—the equivalent of 4.5 ounces a day—were no more likely to develop dementia than noncarriers. (
The study controlled for other variables that are known to affect Alzheimer’s risk including sex, age, physical activity, smoking, alcohol consumption and education.)
APOE4 carriers who ate the most unprocessed meat were at significantly lower risk of dying over the study’s 15-year period and had lower cholesterol than carriers who ate less. Go figure. Noncarriers, however, didn’tenjoy similar benefits from eating more red meat.
The study’s findings are consistent with two large U.K. studies.
One found that each additional 50 grams of red meat (equivalent to half a hamburger patty) that an APOE4 carrier consumed each day was associated with a 36% reduced risk of dementia.
The other found that older women who carried the APOE4 variant and consumed at least one serving a day of unprocessed red meat had a cognitive advantage over carriers who ate less than half a serving, and that this advantage was of roughly equal magnitude to the cognitive disadvantage observed among APOE4 carriers in general.
In all three studies, eating more red meat appeared to negate the increased genetic risk of APOE4.
Perhaps one reason men with the variant are at lower Alzheimer’s risk than women is that men eat more red meat.
These findings might cause chagrin to women who rag their husbands about ordering the rib-eye instead of the heart-healthy salmon.
But remember, the cognitive benefits of eating more red meat appear isolated to APOE4 carriers.
Nutrition is complicated, and categorical recommendations—other than perhaps to avoid nutritionally devoid foods—would best be avoided by governments and health bodies.
Readers can order an at-home test from any number of companies to screen for the APOE4 variant.
The Swedish researchers hypothesize that APOE4 carriers may be evolutionarily adapted to carnivorous diets, since the variant is believed to have emerged between one million and six million years ago during a “hypercarnivorous” period in human history.
The other two APOE variants originated more recently, during eras when humans ate more plants.
APOE4 carriers may absorb more nutrients from meat than plants, the researchers surmise. Vitamin B12—low levels have been associated with cognitive decline—isn’t naturally present in plant-based foods but is abundant in red meat.
Foods high in phytates (such as grains and beans) can interfere with absorption of zinc and iron (also high in red meat), which naturally declines with age. So maybe don’t chuck your steak yet.

From auction floors to TikTok — the professionals who made property education a public good
6 min
Australian property has always been a national obsession, but the way Australians learn about it has changed fundamentally. Where previous generations relied on a real estate agent’s advice and a bank manager’s approval, today’s buyers and investors are walking into the market with suburb-by-suburb data, auction strategy insights and valuation knowledge that would have required a professional consultation five years ago.
The ten creators on this list are the reason why. What distinguishes them from the broader landscape of property content is not their following size but the professional substance behind what they publish. Most have spent years doing the work, valuing, buying, negotiating, financing, before they ever picked up a camera. The audience can feel that difference, even when they cannot articulate it.
Today’s buyers are walking into the market with knowledge that would have required a professional consultation five years ago. These ten creators are the reason why.
1 –Tom Panos: Founder, Real Estate Gym
Tom Panos is the highest-profile real estate trainer in Australia, which is a distinction earned over more than two decades of working directly with agents, auctioneers and principals across the country. The content he publishes, on auction strategy, market psychology, agent mindset and the mechanics of negotiation, is backed by a career that predates social media by years.
What makes his presence exceptional is that he speaks to both sides of the transaction simultaneously. Agents follow him for craft. Buyers and investors follow him for intelligence. It is a rare position, and it explains why his audience has grown consistently through every market condition since he began publishing.
2 – Belinda Botzolis: Certified Practising Valuer; Founder, “The Valuer”
The gap that Belinda Botzolis identified and occupied is one that, in retrospect, seems obvious: professional property valuation, made accessible on social media. With seventeen years of practice as a Certified Practising Valuer, more than 15,000 individual property valuations completed, and over $12 billion in real estate assessed, she brought to social media something most content creators in this space cannot fake, a professional opinion.
The response has been significant. Over 20 million TikTok views for valuation content is not an accident. It reflects an audience that has long wanted access to qualified property analysis and found it, for the first time, without having to pay for a report.
3 – George Markoski: Founder, Positive Property
The credibility order matters in property investment content. George Markoski built a portfolio of more than 100 investment properties and retired at thirty-seven on passive income before he built a social media following. That sequencing, wealth first, content second, is the foundation of why his audience trusts him with decisions that carry six and seven-figure consequences.
His content covers RBA decisions, APRA changes and property cycles with the kind of strategic depth that comes from having navigated them personally. He is not forecasting the market from a position of theory. He is reporting from a position of ownership.
4 – Ravi Sharma: Founder, Search Property
Ravi Sharma‘s differentiator is structural: he runs an actual buyer’s agency. The suburb analyses, growth projections and investment frameworks he publishes on YouTube and social media are not constructed for content, they are the methodology his business uses to advise paying clients on real transactions. With more than 114,000 YouTube subscribers and a Bachelor of Business in Real Estate, his content sits at the intersection of professional advice and public education.
The result is content that reads like genuine analysis rather than commentary, because in most cases it is.
5 – Damien Cooley: Director, Cooley Auctions
Damien Cooley has called more auctions on live television than almost anyone in the country, a five-time premiere auctioneer on The Block, and 2015 Auctioneer of the Year. As Director of Cooley Auctions, his authority comes from decades on the rostrum in front of real buyers and real stakes, not from a studio.
His social presence extends that same on-the-ground credibility online, breaking down auction strategy and market sentiment for an audience that wants to understand the mechanics of a sale, not just the result.
6 – Ella Cas: Buyer’s Agent
As a buyer’s agent operating across Melbourne and its surrounding suburbs, Ella Cas brings professional transaction experience to a TikTok presence that covers market trends, price predictions and first home buyer strategy in the Victorian market. What distinguishes her content from general property commentary is its specificity: she is talking about markets she works in, for outcomes she is paid to deliver.
For Melbourne buyers navigating one of Australia’s most competitive property environments, that local professional knowledge, delivered in an accessible format, is exactly the kind of content that earns genuine audience loyalty.
7 – Gavin Rubinstein: Founder, The Rubinstein Group at Ray White TPG
Gavin Rubinstein built The Rubinstein Group at Ray White TPG into one of Sydney’s highest-performing individual real estate practices, and his Instagram engagement outranks every major franchise account in the country. That distinction matters: he is not a media personality who sells property, he is a top-performing agent whose content reflects live transactions in one of Australia’s most competitive markets.
For buyers and sellers trying to understand how Sydney’s top end actually moves, his day-to-day content is closer to a transaction diary than a highlight reel.
8 – Robbo Roper: Mortgage expert & home buyer connector
Robbo Roper‘s content sits at the junction of property aspiration and mortgage reality, which is precisely where most first home buyers get stuck. As a mortgage expert and home buyer connector, he publishes short-form video that walks Australian buyers through the finance side of property ownership: what to expect from a broker, how to prepare for a loan application, what the common mistakes look like.
His placement in Favikon’s Top 20 Australian real estate influencers for 2025 reflects an audience that is not just watching but acting, the kind of content engagement that distinguishes an education account from an entertainment one.
9 – Michael Biviano: Property developer; business coach & real estate strategist
Michael Biviano built his platform on the strategy side of the business, working as a speaker, business coach and property developer before turning that experience into content for agents and investors navigating the industry. His focus sits less on individual listings and more on the frameworks behind sustainable success in real estate.
That distinction, teaching the business of property rather than just showcasing it, is what places him among the professionals worth following rather than just watching.
10 – Consulting by PK: Investment property educator
The property content space has no shortage of people telling audiences what to buy. What is rarer, and more valuable, is someone teaching them how to decide. Consulting by PK builds investment theses from actual data: top 5 per cent growth property analysis, cashflow modelling, suburb research methodology, the frameworks behind the conclusions rather than just the conclusions themselves.
With more than 60,000 YouTube subscribers, the audience that follows this content is a specific and self-selecting one, investors who want to understand the process, not just receive the output. That is a harder audience to build and a more durable one.
What this list reflects, taken together, is a professionalisation of property content in Australia. The era of anonymous property spruikers making market predictions without credentials or accountability is being displaced, slowly, but measurably, by practitioners who are willing to put their professional reputation behind what they publish. That is good for the industry. It is better for the buyers.
