What We Talk About When We Talk About Diet
What We Talk About When We Talk About Diet
On food philosophy, the long view, and why the argument keeps missing the point.
There is a word that didn’t used to mean what it means now. Diet. It comes from the Greek — diaita — which meant a way of life. Not a plan. Not a protocol. Not something you go on and come off. A way of living.
Somewhere along the way we narrowed it down to a six-week program and a before photo.
I’ve been thinking about this all week. Monday I laid out three eating patterns — Mediterranean, Blue Zone, Nordic. Wednesday I looked at what the research says about health outcomes. Friday I listed three apps that can help you track. All of it useful. None of it, by itself, the point.
The point is harder to write down.
What the long-running populations actually share
If you study the places where people routinely live well into their eighties and nineties — and researchers have, for decades — you find the same handful of things underneath the different foods.
They eat mostly plants. They don’t eat much processed anything. They move through the day rather than exercising in concentrated bursts. They eat with other people. They have reasons to get up in the morning that aren’t work.
The food varies. The principles don’t.
Mediterranean people eat olive oil and fish. Okinawans eat sweet potatoes and tofu. Sardinians eat sheep’s milk cheese and sourdough bread. Nordic populations eat fatty fish and root vegetables and rye. None of these groups are eating the same things. All of them are doing something that looks remarkably similar underneath.
Real food. Not too much. Mostly plants. Eaten with intention and company.
That’s it. That’s the long view on diet.
Why the argument keeps missing it
The nutrition conversation in this country is loud and mostly confused. Every few years a new villain arrives — fat, carbs, sugar, seed oils, red meat, lectins — and a new hero to replace it. The argument is always framed as a battle between two things, and whoever wins becomes the next protocol.
The long-running populations aren’t having this argument. They’re eating what their grandmothers ate and not thinking about it very much.
The disconnect isn’t scientific. It’s philosophical. We’ve turned food into a problem to be solved rather than a practice to be kept. And the solution industry — the apps, the books, the programs, the supplements — depends on the problem staying unsolved.
A retired dirt farmer notices this. You spend 26 years watching things grow and you develop a certain skepticism for systems that require constant intervention. A field that needs something new every season usually has something wrong with it at the root level.
What I actually do
I cook closer to Mediterranean than anything else. Not because it’s the best diet in some absolute sense — because it’s the pattern most supported by the longest research record, and because the food is good, and because it doesn’t require me to track anything or eliminate anything or feel guilty about anything.
I eat olive oil on most things. I eat a lot of vegetables. I eat fish more than meat. I eat legumes regularly. I don’t eat much processed food because processed food generally doesn’t taste as good as real food when you know how to cook.
I use an app occasionally to see where I actually am versus where I think I am. Then I put the app down.
That’s not a protocol. It’s just paying attention.
The longer view
Food is one of the places where the long view matters most and gets applied least. We eat thousands of meals a year. The effect of any single meal is essentially zero. The effect of the pattern over decades is enormous.
That’s a farming truth. You don’t judge a field by one day’s weather. You judge it by what you’ve been doing to the soil for the last ten years.
The question worth asking isn’t what diet is best. It’s what pattern can I actually keep — that’s made of real food, eaten with some intention, for the rest of my life.
That’s the one that works.
