Finding the world’s best diet: What global gastronomy can teach us about how to eat


Finding the world’s best diet: What global gastronomy can teach us about how to eat

Kimchi, a traditional Korean dish, is one of the world's healthier local delicacies.

I’m in hospital to see my dad. He’s sitting up and chatting away like he’s propping up the bar at his local — but he’s here because his heart has failed. Dad drinks, smokes and eats a poor diet. The kind of diet I wouldn’t serve to a dog. But he is not alone. He is surrounded by some very sick people who are also in hospital because they have bad diets. My dad is skinny on his; most are large on theirs.
On the next ward, a patient is morbidly obese. He’s served hospital food three times a day and tops it up with snacks from the tuck trolley. Brimming with brightly packaged sugar and fat bullets with a shelf-life beyond the apocalypse, the trolley offers an array of saturated fats, hidden sugars, salt and thousands of ingredients that are more at home in a laboratory than a kitchen. He buys himself a selection for the day that most of us couldn’t eat in a week.
This is an extreme example, but it’s a snapshot of modern Britain. On the one hand, the food revolution of the past 50 years has brought us choice and convenience; on the other, we’re facing a global epidemic with obesity.
Now, I love food. It’s fuel, it’s medicine, and it’s delicious. So when I was asked to go on a journey to find the world’s best diet, I was excited. I eat pretty healthily, but I could definitely do better — and when my dad’s not looking, I’m nicking his Jaffa Cakes. So which countries hold the secret to a longer and healthier life? Might it just be possible that I could find a diet that will ultimately prolong my life? And will I still be able to eat the odd Jaffa Cake?
What I found along the way was not only surprising, it also had the potential to change my life. And if a few of these lessons could be applied on a national — or even global — scale, then they could help towards making the world a healthier place …


MARSHALL ISLANDS IN THE SOUTH PACIFIC


Peering out of the airplane window, it looks as though we’re touching down in paradise: azure waters lapping a sun-soaked shore dotted with palm trees. But once the wheels sink into the greasy tarmac, it becomes quickly apparent that we have landed in one of the most obese places on the planet.
In 2013, the International Diabetes Federation found that more than 80% of the adult population is overweight. And you can see it. Baggage handlers, airport security and the chaps at passport control are all demonstrably carrying extra pounds. And with all this weight come some very grave consequences. The Marshallese have the third highest prevalence of diabetes in the world — 50% of people aged over 35 have the disease, and amputees can be seen island-wide as a result.
So where did it all go wrong? Fifty years ago, the Marshallese suddenly changed their diet. After the Second World War, the islands became a trust territory of the United States. The U.S. began trading with the islands, and as a result the Marshallese diet shifted from fresh fish and coconuts to an imported, processed “Western” diet of flour, white rice, sugar and fatty meats. And this is the diet they still eat today.
One evening I ate with a local family at home — mum, dad and five beautiful children. On the menu were two types of white rice — one with sugar and one without — and turkey tails. Turkey tails are essentially a turkey’s derriere. And, I quickly discovered as turkey fat dripped down my chin, they don’t pack much muscle in their trunk, since their tails can contain a staggering 73% fat. So much fat that they have been banned in countries such as Samoa.
And with a watermelon costing $38 in the local supermarket, there wasn’t a fruit or vegetable in sight. The island is a coral atoll, so growing fruit and vegetables is nigh-on impossible. And on the average wage of $2 an hour, imported fruit and vegetables are a luxury most people can’t afford.
Rice, flour, sugar and fatty meats are a lethal combination if you don’t add any fibre in the mix. Without it, diabetes is almost an inevitability.
SOUTH KOREA
It was way past my bedtime. Armed with a strategic power nap and a box of doughnuts, I shuffled up a back alley. Punctuated with neon, it was like something out of Blade Runner. I arrived at an apartment and a pretty, petite South Korean girl opened the door. Not the racy madam I was expecting. Hyo-Jin tucked the doughnuts under her arm and ushered me into her bedroom. She gave me a slick of red lipstick, smoked my eyes and tamed my mane. We were ready.
I was about to participate in something pretty radical. Eating alone in South Korea is a major social taboo. Mokbang is the antidote. It means “broadcast eating,” something that is taking the country by storm and is earning Hyo-Jin a small fortune. Her live stream is free to watch, but if people are happy with the service they can give a donation. We tucked into an array of South Korean delights: kimchi pancake, fried pork in soy, and something a little more familiar, fried chicken. In just an hour of eating on a webcam, we’d made a few hundred dollars.
With such a passion for food, it is perhaps surprising that South Koreans are some of the slimmest people on the planet. In 2012, a report from the Organisation for Economic Cooperation and Development found that they have the lowest level of obesity in the developed world. So why are they so healthy? Firstly, and very simply, they eat an inordinate amount of vegetables. They eat more than twice the amount of vegetables we do and grow enough to have 222 kg of vegetables per person available every year over our 94 kg. Instead of five a day, it’s more like 10 a day. Fresh and often raw vegetables are a staple everywhere, even at service stations. This is a far cry from our roadside Ginsters and packets of crisps.
Second, fermented foods are a major part of their diet. Kimchi — a spicy, fermented cabbage — is eaten at breakfast, lunch and dinner, with the average South Korean consuming a hefty 150g-200g per day in the winter, and 50 g-100g in the summertime. Packed with good bacteria called lactobacilli, it helps boost metabolism and aids digestion.
Fit to burst, I rolled out of Hui Jin’s flat. Feeling slightly objectified, I did genuinely believe, perhaps naively, that I had provided company at dinner for a few hundred solo eaters. I asked her what I should do about my bloated tummy. She had a one-word answer: “Kimchi.”
ITALY
Tucked away in the Italian countryside, just a couple of hours from Rome, stands a magical hilltop. Known by scientists as the “village of eternal youth,” the average life expectancy in Campodimele is 95 years. Compare that with the Italian average of 77.5 for men and 83.5 for women. In addition, their cholesterol levels are some of the healthiest in the world. In the Eighties, the World Health Organisation discovered that the cholesterol in 80?year-olds was similar to that of newborn babies.
Why are they living so long? There’s no doubt that they have longevity in their genes. Yet it’s what they do with those genes. I spent a day with Geraldo and Liana. They are 85 and 83 respectively, yet look and move like they’re at least 10 years younger.
I ask them to show me what they eat. Geraldo invites me on his Vespa, and I am half-expecting him to take me to the supermarket; instead, we roll down the hill to feed his chickens and check on his wheat fields. As for the supermarket, he laughs and tells me that the closest one is 50 kilometres away and he’s never been.
On returning home, his wife Liana is preparing lunch. A delicious rustic feast of pasta, passata, chickpeas, lashings of olive oil, and a substantial goblet of deep, fruity red wine poured from an old Evian bottle. The difference is that every single element is home-grown and homemade. Being almost completely self-sufficient, each week this couple spend a few euros on just two extras — milk and coffee.
Geraldo and Liana are not an exception to the rule. Professor Cugini has studied the town since the ’80s and refers to their diet as “hyper-Mediterranean.” It’s all the best bits of the Mediterranean diet, turned up full blast. The villagers enjoy top-quality, home-produced fresh ingredients that are packed full of vitamins and minerals. Their diet is low in meat and almost devoid of red meat and butter.
The people here consume an average of one litre of olive oil a week, the perfect recipe for heart health — washed down with two glasses of red wine a day to offer a daily injection of antioxidant polyphenols.
Despite running water and electricity, the people in Campodimele are living a life much as they would have done 1,000 years ago. This isn’t feasible for most of us, but if we all ate a little more like them, we might just feel the benefits.
One can only hope that somewhere in a parallel universe, the tuck trolley being wheeled around my dad’s hospital ward is loaded with a Campodimele harvest and, rather than crisps and chocolate, it is fresh vegetables and olive oil that are being administered.

HEALTH ALERT: Tomato-Rich Diet Reduces Prostate Cancer Risk

Formulating Foods explores the latest health and nutrition news and research—as well as the latest ingredient and food application innovations—to determine what consumers want (and need) from the food and beverage products they consume, and how industry can make it happen.

Tomato-Rich Diet Reduces Prostate Cancer Risk

Men who eat more than 10 portions of tomatoes per week have an 18 percent lower risk of developing prostate cancer, likely due to lycopene, an antioxidant found in tomatoes.

With 35,000 new cases every year in the United Kingdom, and around 10,000 deaths, prostate cancer is the second most common cancer in men worldwide. Rates are higher in developed countries, which some experts believe is linked to a Westernized diet and lifestyle.

To assess if following dietary and lifestyle recommendations reduces risk of prostate cancer, researchers at the Universities of Bristol, Cambridge and Oxford looked at the diets and lifestyle of 1,806 men ages 50 to 69 years with prostate cancer and compared with 12,005 cancer-free men.

The study, published in the medical journal Cancer Epidemiology, Biomarkers and Prevention, is the first of its kind to develop a prostate cancer “dietary index" which consists of dietary components—selenium, calcium and foods rich in lycopene—that have been linked to prostate cancer.

Men who had optimal intake of these three dietary components had a lower risk of prostate cancer. Tomatoes and its products—such as tomato juice and baked beans—were shown to be most beneficial, with an 18-percent reduction in risk found in men who eat more than 10 portions a week.

Researchers suspect these benefits can be attributed lycopene, an antioxidant which fights off toxins that can cause DNA and cell damage.

In addition to its health benefits, lycopene can be used to color food and beverage products. Specifically, two color ingredients are derived from tomato lycopene—tomato lycopene extract and tomato lycopene concentrate.

What's more, using lycopene to color products can also aid manufacturers who are interested in producing clean-label products—not only is lycopene exempt from certification, per FDA, but consumers have also began identifying lycopene with its health benefits, making it easy to recognize on product labels.

Organic Food May Contain More Antioxidants Versus Conventional

Organic Food May Contain More Antioxidants Versus Conventional

Organic foods and crops—including fruits, vegetable and grains—may have more antioxidants and fewer, less frequent pesticide residues than their conventional counterparts.

A recent study looked at 343 peer-reviewed publications comparing the nutritional quality and safety of organic and conventional plant-based foods, and found that overall, organic crops had 18 to 69 percent higher concentrations of antioxidant compounds. Specifically, the organic crops had 19 percent more phenolic acids, 69 percent more flavanones, 28 percent more stilbenes, 26 percent more flavones, 50 percent more flavonols, and 51 percent more anthocyanins.

An organic label on food and beverage products can translate to a healthy bottom line for manufacturers. In fact, according to this FoodTech Toolbox infographic, sales of products labeled as “organic" reached $8.9 billion in 2013. However, labeling foods as “organic" can open manufacturers up to unwanted legal hassle if not implemented correctly.  (For a closer look at the legal implications of food product labeling, check out the FoodTech Toolbox slide show, “Legal Pitfalls in Marketing and Labeling Food Products.")

Since organic farmers are not allowed to apply synthetic pesticides, the research also unveiled that pesticide residues were three to four times more likely in conventional foods than organic ones.

While crops harvested from organically-managed fields sometimes contain pesticide residues, the levels are usually 10-fold to 100-fold lower in organic food, compared to the corresponding, conventionally grown food. Specifically, researchers found that conventional crops had about twice as much cadmium, a toxic heavy metal contaminant, as organic crops. They hypothesized that certain fertilizers approved for use only on conventional farms somehow make cadmium more available to plant roots.
