Food is one of the most visceral parts of any trip abroad. It can make a journey unforgettable or, quite literally, send a traveler to bed. For Americans in particular, the gap between the familiar and the foreign can be surprisingly wide. In 2024, 107.7 million Americans traveled abroad, representing an increase of 108% compared to 2019. That enormous wave of outbound travelers means millions of first-time encounters with cuisines that are entirely outside their comfort zone. Some of those encounters are joyful. Others, not so much. From spice levels that send taste buds into shock to food safety concerns that ruin an entire trip, here are the countries where American tourists consistently struggle most with the local food.
India: The Spice Barrier and the Stomach Test
India is one of the most culinarily complex destinations on earth, and that complexity is precisely what makes it so challenging for American visitors. The country’s cuisine varies enormously by region, relies heavily on intense spice combinations, and features ingredients and cooking techniques that most Americans have never encountered at home. While Latin American flavors are a favorite for about a quarter of American consumers, mainland Asian flavors only register with around 14% of them, which gives a sense of just how unfamiliar deeply spiced South Asian food can feel for the average American palate.
Beyond the flavor challenge, India also presents a genuine food safety concern. Destination is the single most important risk factor for developing traveler’s diarrhea, and high-risk regions include the developing countries of Latin America, Africa, Asia, and parts of the Middle East, which have reported attack rates ranging between 20 and 75%. Traveler’s diarrhea is the most common travel-related illness, and the highest-risk destinations are in Asia (except Japan and South Korea) as well as the Middle East, Africa, Mexico, and Central and South America. For Americans accustomed to strict restaurant hygiene standards, navigating street food stalls and local eateries in India without getting sick requires careful judgment that many first-timers simply don’t have.
China: Unfamiliar Ingredients and a Communication Wall
China presents a unique set of challenges that go well beyond just taste preferences. The cuisine is extraordinarily diverse across its many regions, and many dishes feature ingredients – from century eggs and fermented tofu to various organ meats – that most American tourists find deeply unfamiliar. In heavily visited areas, you’ll often find watered-down flavors designed to appeal to the broadest audience, stripping away the character that makes local food special. This creates a strange paradox where tourists either eat something authentically Chinese that shocks them or end up at a tourist-facing restaurant that disappoints everyone.
China also falls into an intermediate food safety risk zone. Areas of intermediate risk include China, southern Europe, Israel, South Africa, Russia, and several Caribbean islands, where attack rates of 8% to 20% have been recorded among travelers. The language barrier adds another layer of difficulty, as menus in smaller Chinese cities are often not translated, making it nearly impossible to know what you’re ordering. Sources of clean water may be limited, and sanitization techniques may not be adequate to ensure that food is prepared safely, which means even careful eaters can find themselves caught off guard.
Morocco: Bold Flavors and Food Safety Challenges in North Africa
Morocco is one of the world’s most praised culinary destinations, offering rich tagines, preserved lemons, and layers of spice built over centuries of Berber, Arab, and Andalusian influence. But for American visitors, the sheer intensity and unfamiliarity of those flavors can be overwhelming. There’s the issue of traveler expectations – many tourists arrive with the wrong image of a country’s cuisine, expecting Instagram-worthy plates or constant spice explosions, only to be disappointed when reality doesn’t match the hype. The reverse is equally true: many Americans expect something mild and are surprised by how assertive North African seasoning really is.
Morocco also sits firmly in the high-risk category for food-related illness. High-risk areas for traveler’s diarrhea include developing countries in Africa, Asia, the Middle East, and Latin America. Seasonal variation in the incidence of infection has been documented in countries such as Morocco, where bacteria are isolated more commonly in the wet summer and fall months. Street food is central to the Moroccan experience, but street vendors in many developing countries may not be held to the same food safety standards as restaurants, which may also have lower standards than what a visiting digestive system is accustomed to. For American tourists unaccustomed to this reality, the consequences can derail an entire vacation.
Japan: Cultural Precision and the Raw Food Frontier
Japan might seem like a surprising entry given its global reputation for incredible food, but the country presents its own brand of challenge for American tourists. Raw fish, fermented soybeans, sea urchin, and dishes built around umami rather than the salt-sugar-fat combinations Americans tend to favor can feel profoundly alienating to some visitors. Japan has seen a staggering 50% increase in U.S. tourists between March 2019 and 2024, meaning more Americans than ever are sitting down at traditional Japanese restaurants with very little cultural preparation. The expectation of enjoying sushi or ramen doesn’t always translate to enjoying fermented miso soup for breakfast or raw egg on rice.
Interestingly, Japan is one of the few Asian countries that actually sits in the low-risk category for traveler’s illness. Low-risk areas include the developed countries of North America, Central Europe, Australia, and Japan. So the struggle here is almost purely cultural and sensory rather than medical. For American food travelers, a city’s food scene influences where 92.1% of them choose to visit, and Japan consistently tops those wish lists. Yet the reality of sitting through an omakase course that features dishes with textures and flavors nothing like anything back home can leave even adventurous eaters overwhelmed. The gap between anticipation and experience is particularly sharp here.
Thailand and Southeast Asia: The Heat Is Real
Thailand, Vietnam, and their Southeast Asian neighbors enjoy glowing reputations in the global food community. In 2023, the top food tourism destinations included Italy, France, Japan, Thailand, and Mexico, and American tourists flock to Bangkok and Chiang Mai in enormous numbers each year. The problem is that the version of Thai or Vietnamese food most Americans know at home has been significantly adjusted for local tastes. Authentic Southeast Asian street food is far spicier, more pungent, and more texturally diverse than anything served at a typical American Thai restaurant.
The safety challenge is equally real. Arcobacter, a food-borne pathogen, has been identified in food at tourist restaurants in Thailand, suggesting a clear food-borne pathway of transmission. Both the destination and the season of travel affect the identity of the predominant causative organism, with Campylobacter jejuni being relatively more common in Southeast Asia, particularly Thailand. Food and water-borne illnesses can occur anywhere, but developing countries pose the highest risk, including most countries in Asia (excluding Japan), as well as Africa, the Middle East, Central and South America, and Mexico. For Americans expecting a flavor profile similar to their neighborhood Thai takeout, the real thing is often an exciting but sometimes overwhelming shock to the system.
Mexico: Familiar by Reputation, Challenging in Reality
Mexico is the most visited foreign country for Americans, and most U.S. tourists feel completely at ease with the idea of eating there. After all, Mexican food is one of the most popular cuisines in the United States. Millennials and Gen Z are the first generations to say they prefer Mexican food to Italian. Yet authentic Mexican cuisine – regional moles with dozens of ingredients, complex pozole, chapulines (grasshoppers), and huitlacoche (corn fungus) – is nothing like what Americans are eating back home. The familiarity is an illusion, and it leads tourists to lower their guard in ways that can cause real problems.
Mexico is one of the most significant destinations for food-related illness among American travelers. The highest-risk destinations for traveler’s diarrhea include the Middle East, Africa, Mexico, and Central and South America. Many travelers agree that certain destinations don’t cater well to outsiders’ palates or fail to showcase their cuisine’s potential, and off-resort Mexico can confront Americans with preparations and ingredients that feel genuinely foreign despite the familiar labels. A recent survey found that roughly seven in ten travelers say they spend more on food and drink abroad, and in Mexico, where street food is cheap and everywhere, that spending often comes with a side of unpredictability that many American stomachs simply aren’t built for.
