Greek Grilled Octopus with White Beans

Octopus records some of the highest taurine values in food composition surveys — higher than most fish, in the same league as scallops. The reason anyone outside a Greek taverna cares is a widely covered paper (Science, 2023) showing that blood taurine declines with age across species, and that restoring it extended median lifespan in mice by 10–12% and improved bone density, muscle strength, and glucose handling in middle-aged monkeys. In humans the same paper could only show associations — lower taurine went with worse metabolic health — so a plate of octopus is best understood as a sensible way to eat, not a treatment.

Everything around the octopus here has been tested more directly. The largest Mediterranean-diet trial (The New England Journal of Medicine, 2018) — republished after a correction to its randomization, with conclusions intact — found roughly 30% fewer major cardiovascular events among people assigned a Mediterranean pattern supplemented with extra-virgin olive oil. And in a randomized crossover trial of 200 men (Annals of Internal Medicine, 2006), higher-polyphenol olive oil raised HDL and lowered markers of oxidized LDL compared with refined oil — hydroxytyrosol and its relatives are the polyphenols credited. Neither trial isolates octopus; both endorse the plate it sits on.

Why this works

Octopus is lean protein dense in taurine and B12. White beans are one of the best potassium foods per serving; a large systematic review (BMJ, 2013) linked higher potassium intake to lower blood pressure and a 24% lower stroke risk. Extra-virgin olive oil goes on generously and mostly raw, which preserves the polyphenols the crossover trial measured. Lemon, dried oregano, red onion, and parsley are the traditional Greek finish — the onion adds a quiet dose of quercetin.

How to make it

1. Simmer a whole cleaned octopus (about 1 kg) in barely bubbling salted water with a bay leaf for 45–60 minutes, until a knife slides easily into the thickest tentacle. Cool slightly and cut into tentacle portions.
2. Warm 2 cups of cooked white beans with 2 tablespoons of olive oil, a squeeze of lemon, and a pinch of oregano; keep warm.
3. Toss the octopus with a little oil, then grill or sear over the highest heat 2–3 minutes per side, until charred at the edges.
4. Spread the beans on a platter and lay the octopus over them.
5. Scatter thinly sliced red onion and parsley, add lemon wedges, and finish with your best olive oil, oregano, and flaky salt.

Serves 2–3. Leftover octopus keeps well and is excellent cold over the same beans for lunch.
