The most talked-about novel of 2026, “Yesteryear,” dramatizes the tradwife trend that Instagram and TikTok can’t seem to get enough of.

Influencers like Ballerina Farm have turned an agrarian lifestyle into a true social media phenomenon, and Caro Claire Burke’s bestselling book is making it even bigger.

Even Anne Hathaway is bewitched — she’s purchased the novel’s film rights.

But the trend isn’t just about rustic aesthetics, sourdough starters and nostalgia.

As late-summer harvest season gets into full swing, popular accounts that showcase homesteading — growing and raising food close to home — are tapping into something much bigger.

It turns out that keeping chickens, growing vegetables and building family-centered lives aren’t just good for driving social-media clicks.

They’re also habits associated with better long-term health, medical researchers increasingly find.

And that’s something Americans urgently need.

Chronic disease has become this nation’s defining public-health challenge: 76% of US adults and 40% of our children live with at least one chronic disease.

Aside from genetics these diseases, generally speaking, are shaped by daily behaviors, daily environments and access to care over time.

So why are so many of us sick?

And can our sudden fascination with historic ways of living — lifestyles that look very different from our own — help us find a solution?

Those are the questions I was pondering when I traveled to Amish country recently.

I arrived curious about a different culture — and left with a new perspective on modern medicine.

It wasn’t the horse-drawn buggies that struck me, but what I learned about the health of the people riding in them.

When researchers at the University of Maryland assessed more than 5,300 “Old Order” Amish adults in Lancaster County, Pa., against a national comparison group, they found dramatically lower rates of diabetes (3.3% vs.13.2%), hypertension (12.7% vs. 37.8%), and high cholesterol (26.2% vs. 35.7%) among the Amish.

Similarly, Ohio State University researchers found that cancer rates among Amish residents of Holmes County, where I visited, were just 56% of the US average.

Amish children, researchers have found, show remarkably low rates of asthma and allergies.

It’s not yet clear why, but the evidence suggests that the daily practices Amish communities have quietly embraced for generations, and are hallmarks of today’s homesteading movement, may be genuinely protective against chronic disease — working outdoors, cultivating and eating locally grown food, and building daily life around family and community.

Consider movement: Old Order Amish adults average approximately 14,000 to 18,000 daily steps.

The average American adult spends roughly eight to nine hours sitting each day — and walks just 4,000 to 5,000 steps.

How about community: Nearly one in three American households is now home to someone living alone, a circumstance that carries up to a 32% higher risk of premature death.

Among Amish individuals, marriage remains nearly universal, and Amish families average just over six children.

There’s also technology: US teens now average more than eight hours of screen time per day outside of school, whereas Amish communities have largely abstained from leisure-time technology use.

Now, consider that modern medicine is increasingly affirming many of these same principles.

The surgeon general warns about loneliness and excess screen time.

The American Academy of Pediatrics calls for kids to spend more time playing outside.

The USDA and the American Medical Association caution against diets dominated by ultra-processed foods.

State legislatures, too, are catching on.

Bipartisan support for “cottage food” reform — that is, removing regulations to make it easier for families to produce and sell homemade foods — has been spreading across red and blue states alike, reflecting a growing recognition that local food production and home-based living still have a place in modern America.

The point isn’t that we must become Amish, nor make every meal from scratch.

It’s that the practices preserved in Amish communities demonstrate that the foundations of good health have been available to us all along.

And our crisis of chronic disease may not be a matter of what medicine is missing, but of what modern life has forgotten.

Perhaps that’s one reason “Yesteryear” has resonated so deeply: The best stories change our perspective long before they change our minds.

The novel’s time-traveling protagonist gets to experience a shortcut through time and space, allowing her to see what would otherwise take years to understand.

I went to Amish country expecting to feel like I was stepping back in time.

I came away wondering whether I’d just caught a glimpse of the future.
