postulates you already practise — tick each one you live by
Every ticked postulate compounds. Start with one you can keep.
Hara Hachi Bu is the Okinawan habit of stopping before fullness. Satiety signals arrive about 20 minutes late, so 80% now feels like 100% soon.
Water before eating supports digestion and mild satiety. Drinking large amounts during a meal can dilute digestive enzymes.
Your insulin sensitivity is highest in the morning. Front-loading calories improves glucose control and sleep quality.
Chewing breaks food down mechanically and starts enzymatic digestion. It also slows the meal so your brain can register fullness.
Miso, kimchi, sauerkraut and kefir feed your gut microbiome. A diverse microbiome supports immunity and mood.
Whole grains keep their fibre and minerals, blunting blood-sugar spikes. Refined flour behaves much like sugar.
Five colours of vegetables daily means five different polyphenol families. Colour is a proxy for antioxidant variety.
Sardines, mackerel and salmon supply EPA and DHA. These fats lower inflammation and support brain and heart health.
Fruit delivers sweetness wrapped in fibre, water and micronutrients. The fibre slows absorption dramatically.
Post-exercise your muscles are primed to absorb nutrients. Protein and carbohydrate within an hour support recovery.
Seasonal food is picked riper and travels less, so it holds more nutrients. It also naturally rotates your diet.
Ultra-processed foods are engineered to override satiety. Treating them as an occasion keeps them from becoming a baseline.
Herbs add flavour without sodium, which matters for blood pressure. Many also carry their own anti-inflammatory compounds.
Green tea provides catechins and a gentle dose of caffeine with L-theanine. The combination gives calm alertness.
Digestion runs on the parasympathetic nervous system. Eating while rushed or stressed impairs absorption.
Late meals raise overnight glucose and disrupt deep sleep. An empty stomach lets your body focus on repair.
Protein preserves muscle mass, which is the single best predictor of healthy ageing. It is also the most satiating macronutrient.
Extra virgin olive oil is rich in monounsaturated fat and polyphenols. It is the fat backbone of the Mediterranean pattern.
A handful of nuts delivers healthy fats, protein and minerals. Studies link regular nut intake to lower mortality.
Broth supplies collagen peptides, glycine and minerals. It is a gentle, warming way to support connective tissue.
Curcumin has documented anti-inflammatory activity. Pair it with black pepper and fat for absorption.
Greens supply folate, magnesium and dietary nitrate. Nitrate improves blood-vessel function and walking efficiency.
Flavoured yogurt often carries as much sugar as dessert. Plain yogurt plus fruit gives you control.
Alcohol disrupts REM sleep and recovery. Containing it to two days protects the other five.
Legumes are the most consistent food across all Blue Zones. They deliver fibre, protein and slow carbohydrate.
Traditional practice favours room-temperature or warm drinks during eating. It keeps digestion comfortable for many people.
Eating vegetables first blunts the glucose rise from the rest of the meal. Order matters as much as content.
Portion perception is visual. A smaller plate makes a smaller serving feel complete.
Natto and tempeh provide vitamin K2 and probiotics. K2 directs calcium into bone rather than arteries.
Seaweed is a dense source of iodine, which thyroid function depends on. It also carries unique minerals and fibre.
Mixed grains raise fibre and lower the glycaemic load. The texture change takes about two weeks to enjoy.
Eggs contain choline, complete protein and fat-soluble vitamins. Dietary cholesterol has little effect on blood cholesterol for most people.
Sweeteners maintain a taste preference for intense sweetness. Some also appear to alter gut bacteria.
It rehydrates you after the overnight fast and gently wakes digestion. A simple, cheap ritual with a real habit effect.
Avocado combines monounsaturated fat, potassium and fibre. Potassium is directly protective for blood pressure.
Occasional red meat provides iron, zinc and B12. Frequent intake, especially processed, raises cardiovascular risk.
Cocoa flavanols improve blood-vessel dilation. Higher cocoa means less sugar per square.
Sprouting reduces antinutrients and raises available minerals. It usually makes grains easier to digest.
Allicin supports immune function and mild blood-pressure reduction. Crush it and wait ten minutes before cooking.
Stress hormones shut down digestion and drive overeating. Three slow breaths before the first bite change the meal.
A consistent overnight fast supports cellular repair and glucose control. Finish dinner early rather than skipping breakfast.
Mushrooms provide beta-glucans for immunity, and vitamin D when sun-exposed. They also add savoury depth without salt.
Grass-fed dairy carries a better fatty-acid profile and more vitamin K2. Quality matters more than quantity here.
Industrial trans fats have no safe intake level. Check labels for partially hydrogenated oils.
Sweet potatoes bring beta-carotene and a lower glycaemic load. They are the staple of Okinawan longevity diets.
Berries are the highest-antioxidant fruit per calorie. Anthocyanins are linked to slower cognitive ageing.
Raw honey brings trace enzymes and antimicrobial compounds. It is still sugar, so use it sparingly.
Poultry supplies complete protein with less saturated fat. Keep the preparation simple and the skin optional.
Chamomile, rooibos and lemon balm are caffeine-free and calming. An evening tea ritual signals the body toward sleep.
A moment of gratitude shifts you into parasympathetic mode. Digestion measurably improves when you are calm.
