\n

A remote peninsula populated by tribes largely untouched by modern civilisation may seem an unlikely place for the latest diet fad to emerge.<\/p>\n

Yet experts believe the traditional eating habits of rural Papua New Guinea may hold vital clues to tackling the Western world\u2019s epidemic of chronic illnesses such as heart disease, obesity and diabetes<\/a>.<\/p>\n

More than 9.1 million people in England are expected to be living with major illness by 2040, according to the Health Foundation \u2013 about 2.5 million more than in 2019.<\/p>\n

Yet in some parts of Papua New Guinea \u2013 one of the poorest countries in the world \u2013 obesity, type 2 diabetes and cardiovascular disease are strikingly uncommon, a phenomenon that has puzzled scientists for decades.<\/p>\n

Now researchers believe they may have found the explanation for such remarkably low rates of chronic illness and longer healthy lifespans: their traditional diet.<\/p>\n

And following impressive trial results, they\u2019ve gone so far as to develop their own easy-to-follow eating plan, inspired by the diets of rural Papua New Guinean villagers, that anyone can try.<\/p>\n

Called the NiMe diet \u2013 short for Non-Industrialised Microbiome Restore \u2013 the plan is notably simple. There is no calorie counting, expensive supplements or complicated fasting schedule.<\/p>\n

Instead, meals revolve around beans and vegetables, with only small amounts of meat or fish and virtually no processed food, dairy or wheat.<\/p>\n

Researchers believe they may have found the explanation for such remarkably low rates of chronic illness and longer healthy lifespans among Papua New Guineans: their traditional diet<\/p>\n<\/div>\n

The aim is not simply to nourish the body but to restore the gut microbiome \u2013 the trillions of bacteria increasingly linked to everything from immunity to metabolism and mental health.<\/p>\n

In a trial carried out in Canada, volunteers who followed the fibre-rich, plant-heavy regime for just three weeks saw improvements in several markers linked to chronic disease. The results showed that participants recorded lower \u2018bad\u2019 cholesterol, improved blood sugar control, reduced inflammation and even lost weight \u2013 despite eating around 2,500 calories a day.<\/p>\n

Lead researcher Professor Jens Walter believes that, long-term, the diet could even help reduce the risk of diseases such as bowel cancer, which has more than doubled in younger adults since the 1990s.<\/p>\n

\u2018Our modern diet has a lot of health benefits, in terms of reducing malnutrition as well as preventing food-related infection and illness,\u2019 says Professor Walter, who lectures in ecology, food and the microbiome at University College Cork. \u2018But these advantages have come with collateral damage. We\u2019ve traded infections and malnutrition for chronic disease.\u2019<\/p>\n

Having studied the microbiome for more than 25 years, he believes this is closely linked to the way our diets have changed over the past century.<\/p>\n

As industrial food production took off, diets based around fresh, simple foods were increasingly replaced by heavily processed products designed to last longer. White bread, packaged snacks and ready meals became staples.<\/p>\n

But while diets changed rapidly, the human body \u2013 and those all-important gut microbes \u2013 did not have time to adapt.<\/p>\n

\u2018Our diet and gut microbiome has changed many times throughout human evolution,\u2019 says Professor Walter. \u2018But the most drastic change was caused by industrialisation \u2013 and it occurred so fast, our biology wasn\u2019t able to catch up with it.\u2019<\/p>\n

The researchers designed meals around ingredients including sweet potato, whole grains such as quinoa and barley, and plant proteins such as lentils, peas and tofu (pictured, sweet potato hash from Dr Armet’s Instagram)<\/p>\n<\/div>\n

\n

\"The <\/div>\n<\/p><\/div>\n

The traditional diet eaten in rural Papua New Guinea is rich in fibrous foods such as leafy greens, fruit and vegetables (pictured, coleslaw from Dr Armet’s Instagram)<\/p>\n<\/div>\n

He believes this mismatch has helped drive soaring rates of obesity, type 2 diabetes and heart disease. Some illnesses \u2013 including colorectal cancer \u2013 have also been linked to low fibre intake (studies suggest about 95 per cent of Britons fail to eat enough).<\/p>\n

The traditional diet eaten in rural Papua New Guinea looks very different. It\u2019s rich in fibrous foods such as leafy greens, fruit and vegetables, contains very little meat or dairy and includes no ultra-processed food.<\/p>\n

According to Professor Walter, stool samples from these communities show low levels of inflammation and a highly diverse gut microbiome \u2013 both linked to better long-term health.<\/p>\n

Studying the microbiomes of Papua New Guineans inspired Professor Walter and his former PhD student, dietitian Dr Anissa Armet, to create a version of the diet using foods easily available in Western countries.<\/p>\n

Rather than relying on Papua New Guinean staples such as sago (a starch from palms), cassava (a starchy root vegetable) and breadfruit (a tropical fruit, which can be prepared like potato), they designed meals around ingredients including sweet potato, whole grains such as quinoa and barley, and plant proteins such as lentils, peas and tofu.<\/p>\n

Small portions of fish, poultry or eggs are allowed daily, while lean red meat is limited to once a week.<\/p>\n

Fibre is central to the plan. While UK guidelines recommend 30g a day, the NiMe diet contains around 45g.<\/p>\n

And, importantly, it is not just about what foods are eaten, but how they are prepared.<\/p>\n

\n
\n
\"Professor <\/div>\n<\/p><\/div>\n

Professor Jens Walter developed the NiMe diet with a former PhD student<\/p>\n<\/div>\n

NiMe recipes require carbohydrates such as whole grains and sweet potatoes to be cooled after cooking to change the starches in them, creating what\u2019s known as resistant starch \u2013 a form that\u2019s harder for the body to break down.<\/p>\n

Instead of being rapidly absorbed, it passes further into the gut where it helps feed beneficial bacteria.<\/p>\n

To test the diet, Professor Walter\u2019s team carried out a three-week trial involving 30 volunteers, mostly healthy men and women aged about 27. All meals and snacks were prepared by researchers.<\/p>\n

The team then analysed blood and stool samples.<\/p>\n

While the volunteers\u2019 microbiomes changed relatively little, many other health markers showed clear improvement. Despite consuming the same calories as before \u2013 about 2,500 a day for men and 2,000 for women \u2013 participants lost weight, averaging 2.5 lb in men and 2.2 lb in women.<\/p>\n

Participants also saw their LDL, or \u2018bad\u2019 cholesterol, fall by 17 per cent.<\/p>\n

Levels of C-reactive protein \u2013 a marker linked to inflammation and heart disease \u2013 fell by 14 per cent. And researchers also noted improvements in blood sugar levels and increases in compounds linked to protection against type 2 diabetes.<\/p>\n

\u2018The high-fibre aspect of the diet showed benefits for gut health as well \u2013 reducing inflammation and rebuilding the gut wall, as well as increasing levels of short-chain fatty acids, which improve digestion and immune function,\u2019 says Professor Walter.<\/p>\n

Participants even saw reductions in markers linked to cancer risk, particularly bowel cancer. \u2018There\u2019s good evidence that colorectal cancer is linked to high consumption of animal fat and low fibre intake,\u2019 he adds. \u2018To prove that the NiMe diet reduces the risk of colon cancer, we\u2019d need a 2,000-person study lasting 20 years. But we could already see markers linked to the disease falling after just three weeks.\u2019<\/p>\n

The scale of the changes surprised even the researchers, who are now applying for funding to study the long-term effects of the diet.<\/p>\n

In the meantime, sample NiMe recipes are freely available online. \u2018We wanted to make it available to anyone,\u2019 says Professor Walter. Yet some experts are more cautious.<\/p>\n

\u2018Any diet high in fruits, vegetables and plant-based foods is likely to produce positive health effects,\u2019 says Dr Gunter Kuhnle, professor of food and nutritional sciences at the University of Reading. \u2018And people in studies like these often lose weight simply because they pay more attention to what they eat.\u2019<\/p>\n

He also warns that scientists still do not fully understand what an ideal gut microbiome looks like. \u2018There are many more ways to improve the gut microbiome than this specialised diet \u2013 eating probiotics is an easy one,\u2019 he adds.<\/p>\n

Dr Ruairi Robertson, a gut microbiome scientist at Queen Mary University of London, believes the NiMe diet does offer something distinctive, however. \u2018What stands out is the much higher proportion of fibre, which has been neglected in the UK for years,\u2019 he says.<\/p>\n

Professor Walter says he\u2019s personally experienced the benefits of changing his diet.<\/p>\n

\u2018I used to be borderline overweight,\u2019 he says. \u2018I was very sporty when younger, but after an injury I stopped exercising and didn\u2019t change the way I ate. It was lots of fatty and sugary junk food. My cholesterol and blood sugar skyrocketed.\u2019<\/p>\n

Despite not following the NiMe diet overly strictly, he says he\u2019s \u2018lost all the weight now\u2019. \u2018My cholesterol has gone back down and I feel much healthier. I feel better in my 40s than I ever have before.\u2019<\/p>\n
