Plants, fibre, protein, oil
Nourishment
The longest-lived populations eat mostly plants, enough protein, a great deal of fibre and olive oil, and they stop before they are full. Everything else is detail.
The Mediterranean and Blue Zone diets have the best long-term evidence of any eating pattern: lower rates of heart disease, stroke, diabetes and dementia in trials and cohorts spanning decades. Their common core is vegetables, legumes, whole grains, nuts, fruit and olive oil most days; fish and fermented dairy often; meat rarely; sweets and processed food almost never. Protein matters more with age, when muscle is harder to keep: around 1.2 to 1.6 grams per kilo of body weight for active older adults, from beans, fish, eggs, dairy and some meat.
How people eat matters as much as what. Okinawans stop at eighty percent; Sardinians and Ikarians eat their main meal at midday and dinner small; Loma Lindans eat early; almost all Blue Zones eat within a window of ten to twelve hours and share the table. Wine, where it appears, is one or two small glasses with food. The rule that survives translation is simple: mostly plants, enough protein, real food, fixed times, in company, and stop early.

On the road
Keeping it on the road.
- Choose the local diet in Mediterranean and Asian destinations; the traditional menu is usually the healthiest thing on it.
- Markets are breakfast: fruit, bread, cheese, yoghurt, nuts. Skip the hotel buffet or treat it as a salad bar.
- Make lunch the main meal and dinner the light one. Most southern cultures already do.
- One glass of the local wine with dinner if you like it; none in the afternoon and none at the airport.

Is the Mediterranean diet the best diet?
It has the strongest long-term evidence for heart and brain health of any pattern, and it is a way of eating people can keep for life. Blue Zone diets are regional versions of the same idea.
Do I need to be vegetarian to live long?
No. Most Blue Zones eat small amounts of meat and plenty of fish or dairy. Loma Linda’s vegetarians do very well, and so do Sardinian shepherds who eat lamb on Sundays. Mostly plants is the rule, not only plants.
What about intermittent fasting?
An eating window of ten to twelve hours with an early dinner is well supported and matches how long-lived populations eat. Longer fasts have less evidence and need supervision.
