Whether we’re talking fat-free, gluten-free, organic, MSG-free, Paleo or vegetarian, every regimen takes on new challenges and pitfalls when you are traveling or living abroad – especially in a country like China, where you may face a language barrier.

Anyone looking for a bit of entertainment or foodie satisfaction while on a layover in Shanghai will need to look well beyond the confines of the airport. Pudong’s international airport may be a huge, mostly gleaming, modern space, but it has some of the most overpriced, bland food and off-brand shopping with little to do beyond making repeated attempts to connect to the free Wi-Fi.

“We grow everything here – kale, dill, peppers, cucumbers, tomatoes, arugula, eggplant, lettuce, cauliflower… everything,” the elderly woman says proudly, waving her hand in the direction of her small field as she digs her worn plastic sandals into the dirt. While she grows the vegetables and herbs, her 80-year-old husband tends his pomegranate trees and takes their products from this patch of farmland at the far northern end of Istanbul’s Sarıyer district to sell at local markets around the city.

When we pick up a hefty, shiny copper pan in his workshop, Emir Ali Enç unhesitatingly claims, “You are now holding the best saucepan in the world.”

Gnarled evergreen mastiha (mastic) trees cling to terraced hillsides throughout the southern part of Chios, a Greek island in the Aegean. These humble trees (Pistacia lentiscus var. chia) have been fought over and cherished for thousands of years because they produce “tears” of delicious and healing sap. The best pharmacists in ancient times used to concoct luxurious healing balms with mastiha sap; Emperor Justinian’s personal physician mixed mastiha and deer brains to make a beauty cream. We haven’t tried that recipe yet.

[Editor's note: We're sorry to report that Harbin Dumplings has closed.] Walk along just about any street in Shanghai these days, and you’ll see an ever-encroaching range of Western brands, standardized brand signage and food franchises. As in other rapidly developing countries, the battle for consumer dollars and brand loyalty has meant more chains and mass-produced food. That’s partly what makes stepping into one of the several Liu Family Harbin Dumplings shops a breath of fresh air. Every morning until the lunch rush, the dining room and back rooms are set up with trays and workers dexterously making every dumpling from start to finish. Dumpling wrappers are meticulously hand-rolled, the fillings are mixed in large batches, and the time-consuming process of filling and closing the dumplings marches on until tray upon tray is ready for boiling – but not until they’re ordered during the lunch rush.

[Editor's note: we're sorry to report that Butifarring is now closed.] Gourmet fast food has swept through Spain at full speed. It comes in multiregional styles and with strong creative inspiration behind it – and, most importantly, the food itself can be exceptional.Eric Camp, Albert Gómez and their three partners are a good example of this, with their sausage-centric project, Butifarring, and their first small venue in Barrio Gòtico, which is much more than a Catalan hot dog or sandwich place.

Let’s say you have only two or three days in Rio. You want to experience a little real Brazilian culture and don’t want to restrict yourself to the obvious tourist stops, overhyped bars and restaurants or usual “gringo” nightlife spots. Our recommendation? Spend a night or day – or both, even – at Feira de São Cristóvão.

A few weeks ago we wanted to get out of bustling Mexico City, but we only had one day free, so we decided to look for a place where we could see some sights, eat, enjoy ourselves and still be back before the day was over. We found not just one, but two gorgeous towns that fit the bill in the state of Hidalgo, just over an hour north of Mexico City. The picturesque town of Real del Monte, also known as Mineral del Monte, is a small pueblo mágico (the Ministry of Tourism’s designation for a unique and historically significant village) with a long and rich heritage. It was one of the first mining towns the Spanish established after La Conquista. Much of the silver and gold mined during the colonial and post-colonial periods came from this part of the country.

Shanghai is famous for its swampy summer weather, and although this August was the coolest in 14 years, it’s still hot and humid out there as we head into Indian summer. Staying hydrated against the rising mercury is crucial if you’re out hunting a meal of street food, so here are the best sips to keep your yin and yang balanced this season. Mia’s Green Apple Mint Juice This neighborhood Yunnan specialty restaurant takes bold flavors from southwest China and elevates them in simple combinations. In many of their noodle and main dishes, mint features prominently - there is even a salad composed entirely of mint leaves that will leave you wondering why anyone is even bothering with iceberg lettuce. By supercharging fresh apple juice with a fistful of pressed mint leaves, Mia’s makes the idea of a juice cleanse just a teensy bit more appealing.

Who says there’s no such thing as a free lunch? In fact, over at Gastronomika, a new Istanbul culinary project, the food is served not only free of charge but also with an intriguing – and ambitious – backstory

Mid-Autumn Festival (中秋节, zhōngqiūjié) lands on the 15th day of the eighth lunar month, relatively near the autumnal equinox; in 2014, it falls on September 5. Also sometimes called Mooncake Festival, it is a public holiday in China and Taiwan on which families gather to give offerings to the full moon, float sky lanterns and eat mooncakes (月饼, yuèbing). A culinary tradition with legendary roots, mooncakes are sold everywhere from grocery stores to five-star hotels and come with competing origin stories that relate how these sweets came to represent the holiday.

Editor's Note: Sadly, this spot is now closed. The busy outer neighborhoods of Rio de Janeiro – locals refer to them as “suburbs,” though they are anything but – are full of old bars. Some of the best botequins (small, family-run establishments serving traditional food) have been kicking around in these parts for ages – but not all of them.

Misty, lush Fırtına Valley is worlds away from Istanbul’s concrete urban hustle. It’s a land of cascading waterfalls, rushing rivers, wild edibles and precipitous hillsides covered with glossy tea bushes. We came to escape Istanbul’s infamous August heat and learn about the region’s special foods. After a week, we had stomped our way through bagpipe-fueled celebratory circle dances and eaten our weight in fried trout and cornbread.

It’s a dirty secret nobody wants to talk about, but let’s put it out there: finding a good cup of Turkish coffee in Turkey can sometimes be very difficult. Thin and watery, rather than thick and viscous, is frequently the order of the day. This is no small matter, akin to complaining about the quality of the French toast in France or about finding stale danishes in Denmark. Turkey, after all, is the land that, during Ottoman times, helped introduce coffee to the rest of Europe. When it comes to making Turkish coffee, Turkey needs to represent.
