Among the least cheerful reading of the past year was the three-part series The Lancet published in November 2025 on ultra-processed food. Two years in preparation, 43 authors, led by Carlos Monteiro of the University of São Paulo, the researcher who gave the world the term in the first place.

Their systematic review covered 104 long-term studies. Ninety-two of them found higher rates of chronic disease among people eating the most ultra-processed food. Pooled analysis linked it to twelve conditions, including obesity, type 2 diabetes, cardiovascular disease, depression and premature death.

Portugal comes out of the European comparisons unusually well. A study in the European Journal of Nutrition, built on the European Food Safety Authority's consumption database, found Portugal among the lowest consumers of ultra-processed food and drink across 22 countries, alongside Italy. The European average sat at around 27% of daily energy. At the far end of the same table, close to 40%, sits the United Kingdom.

For once, in other words, Portugal sits at the good end of a European table.

What Portugal is doing right, mostly by accident

Nobody designed this. It is simply what happened when a food culture built on soup, pulses, fish and bread was slower than its neighbours to be replaced.

Sopa still opens a great many Portuguese meals, and the version most households make is three or four vegetables and some olive oil. Grão and feijão appear on menus without anyone thinking to call them plant protein. Sardines have never needed a marketing campaign. And the municipal market, an institution Britain and Germany largely demolished decades ago, is still where a good many people buy their vegetables on a Saturday morning.

None of that is guaranteed to last. Every force that shifted diets elsewhere is present here too: the longer commute, the two working parents, the cheap convenience option with an advertising budget behind it. Portuguese researchers working on the UPPER project have been tracking the drift for years, and the direction of travel is not upward.

Eight words from England

All of which is the context for something beginning on 1 September that deserves a look, even from readers entitled to feel fairly smug about how they eat.

The Whole Plate is a free movement run by Whole Food Earth, a wholefoods company based in Ramsgate, on the Kent coast. Its annual campaign, Whole Plate September, opens next Tuesday. The philosophy is eight words: most of your plate, most of the time.

Five rules follow, each with a deliberate margin for error.

If your grandmother wouldn't recognise it, think twice. Five ingredients or fewer, almost always. Cook one more meal a week than you did last week. Half the plate given over to plants, with frozen, tinned and dried counting no less than fresh. Treats are not forbidden, provided they are made of real ingredients and eaten deliberately rather than out of a packet on the way past.

Those who sign up receive one short email a day for 30 days, containing a swap, a recipe or a small suggestion. There is nothing to pay, nothing to measure and nothing to order.

Scepticism is reasonable. The campaign is run by a company that sells wholefoods, a fact readers may weigh as they see fit. Set against that, the programme takes no payment and sells nothing, which is not something that can be said of much else arriving by email at this time of year.

The rule that travels

The third rule is the one that survives any move across borders. Cook one more meal a week than you did last week.

Its strength is how little it asks. There is no version of it that constitutes a failure worth worrying about, and a household that keeps it up will reach Christmas having cooked something in the region of sixteen additional meals at home, having given up nothing in the process.

For readers living in Portugal, the raw materials for this are cheaper and better than in most of Europe. A kilo of dried beans costs very little. The fish is the fish. Olive oil is not a luxury item. The gap between intention and dinner is smaller here than it is in Kent, which is presumably why nobody in Portugal has needed to invent a movement about it.

Where to find it

The five rules, the 30-day sign-up and the recipe wall, which is a public collection of home cooking sent in by participants, are at wholefoodearth.com.

The company also operates a Whole Plate Standard, awarded to producers whose labels list nothing a domestic cook would find unfamiliar, and an ambassador scheme for cooks and food writers. Its own trade began in bulk staples: nuts, dried fruit and seeds sold by the kilo rather than the sachet, which is roughly how a Portuguese market has always sold them.

Whole Plate September runs to the end of the month. Joining costs nothing.
