What Are the Hunza Valley Diet Secrets?

The Hunza Valley diet has been described as a model of natural health for about a century. Most of what is written about it comes from travellers' accounts and secondhand summaries, not from dietary surveys. That does not make the food bad, and it does mean that some of what gets repeated as fact is tradition, guesswork or myth. Here is what can be said with reasonable confidence, what cannot, and how to borrow the good parts.

What the traditional diet is usually said to contain

General descriptions of traditional food in Hunza and the wider Karakoram, including the Wikipedia article on the Hunza diet, list a similar set of foods: whole grains such as wheat, barley, buckwheat and millet made into flatbreads and porridges; apricots eaten fresh in season and dried for winter, along with mulberries, apples, grapes and other orchard fruit; walnuts and other nuts; pulses and vegetables including potatoes, carrots and onions; some dairy from goats and cows; and meat eaten less often. Wild herbs are used for teas. Our herbal tea guide covers the ethnobotany of those, and our apricot page covers the fruit.

We want to be clear about the quality of this evidence. We could not find a published dietary survey of the valley that lets us put reliable percentages on any of it, and figures for how many calories people eat or what share comes from grains circulate without a traceable source. So treat the list above as a description of tradition, not measured intake.

Claims that go too far

An earlier version of this page said that refined sugar, processed flour, seed oils and ultra-processed food were "entirely absent" and that apricot kernel oil was the primary cooking fat. We cannot verify either statement, and it is unlikely that any community with roads, shops and tourism today eats exactly as its grandparents did. We have removed the absolutes.

The famous claim of extreme longevity is also unsupported. Researchers who study age claims class the Hunza story as a "Shangri-La myth" and a 2025 paper in The Gerontologist said the 1973 National Geographic report that popularised it was invalidated fairly quickly. Our page on why Hunzakuts are said to live long and our daily routine guide go through the evidence in full.

The valley was not a nutritional paradise

Two real studies show why "perfect diet" is too simple. In 1992 the Journal of the Pakistan Medical Association reported that visible goitre, a sign of iodine deficiency, affected 61.36% of people in the Gilgit and Hunza area before iodised salt was supplied, falling to 4.68% after 12 years. Even then, 70.41% of sampled households had some degree of iodine deficiency. Mountain soil and water can be low in iodine, so iodised salt matters wherever you live.

More recently, a 2025 study in Environmental Geochemistry and Health tested 68 samples of drinking water and green leafy vegetables from the Hunza and Nagar districts and found that, for Hunza, the hazard quotient for chromium, nickel, cadmium and lead exceeded 1 in both water and vegetables, and that lifetime cancer risk estimates for children exceeded the accepted level. The authors called for measures to reduce exposure. It is one study of one set of samples, and it does not describe every household, but it is a good reason not to assume that food from a remote valley is automatically clean. Our Karakoram farming page discusses this further.

What is worth borrowing

The general shape of the traditional diet, mostly plants, whole grains, fruit, nuts and pulses with modest amounts of animal foods, matches what current guidance recommends. The World Health Organization advises at least 400 g of fruit and vegetables a day, at least 25 g of dietary fibre, less than 10% of energy from free sugars, and less than 5 g of salt. A large 2019 analysis in The Lancet found that people eating the most fibre had a 15% to 30% lower risk of death and of several major diseases than those eating the least, and that benefits were greatest at 25 to 29 g a day. Here is how to eat in that spirit today:

• Make whole grains your staple. Wholemeal roti, barley or oats give far more fibre than refined flour.
• Add a pulse or vegetable dish to lunch and dinner. Fibre from grains, pulses and vegetables is where most of the 25 g comes from, and fruit and nuts alone will not get you there.
• Eat fruit in season, and keep dried fruit to a small handful, since drying concentrates sugar.
• Use nuts as a snack, about a handful of walnuts a day, within your energy needs.
• Treat honey as sugar. It counts toward the WHO limit, so a teaspoon replacing sugar is reasonable and a spoonful on top of everything else is not.
• Use iodised salt, and keep total salt below 5 g a day.
• Move. The WHO recommends 150 to 300 minutes of moderate activity a week, which is probably the most valuable "Hunza habit" of all, although we do not have measured step counts for the valley.

The apricot kernel oil, glacial water and herbal teas that appear on most "Hunza diet" lists are the least evidence-backed parts. For the oil, read the safety note on our kernel oil page, and for the teas see our herbal tea guide.
