How to eat adventurously abroad without getting sick

Eating adventurously abroad is possible if you take the right precautions before you travel.

When you travel, eating is pure joy – most of the time.

In fact, some people base their entire vacations around noshing on exotic dishes. We all enjoy a memorable meal, and there are regions around the world that boast cuisines unlike any other. Tuscany, India, Brazil, Scandinavia, Greece, Japan – you name a country, and they will likely have their own distinct flavor, culture and history around culinary creativity.

However, medical problems happen while traveling abroad too. There are many reasons Americans get sick while they travel. No one wants to go on vacation and wind up falling ill, but it happens, and many of these instances can be traced back to your last meal.

Why we get sick when we travel abroad
When you leave your home country and cross boundary lines, you are entering a region with a completely new set of pathogens and bacteria your body might not be prepared for. Your immune system has grown accustomed to what you consume on a daily basis. When it encounters a microbe it's unfamiliar with – it's first response is to get rid of it, whether or not the food is spoiled or contaminated. 

For foodies, this can pose a major predicament. 

If you are one of these travelers, don't fret. There are things you can do to prevent these illnesses from happening, many of which can be performed before you leave on vacation.

Here are few to get you started:

Get vaccinated: The Centers for Disease Control and Prevention does a great job sending out timely updates about which countries are currently unsafe for travel, and they also will give you expert advice about which vaccines are appropriate for the region. For the most part, you will need to receive your vaccines about 6 to 8 weeks before you head out on your trip.

Prepare your body for the trip: Keep your health in tip-top shape and your immune system prepared for a harsher bacterial environment. Eating healthy and exercising regularly are good ideas.

Drink bottled water upon arrival: Bacteria and microbes thrive in tap water. While locals will be just fine drinking it, your body might have a different reaction. Stock up on bottled water and avoid public water fountains. If you're in a country where visitors often get sick, don't even use tap water to brush your teeth with it.

Only eat fruits and veggies you can peel: In developing countries, agricultural practices are vastly different. Many nations use substances that might be banned in the U.S. So it's important you stick to vegetables that have thick skins (like bananas and watermelons) and avoid other fruits where these substances can creep in, like berries.

Buy travel insurance: It's not guaranteed that your health care coverage will apply to your visit abroad. With a trip insurance package, you can make things easier on yourself as well as protect your health and travel investment in another country.

Inspect the vendor: When you first enter a foreign restaurant, make sure that the place serving you appears clean. Take a look at the preparation surfaces, aprons and hands of the people preparing the food. Also keep an eye out for an efficient washing station on the premises. These are all signs that you are eating in a safe environment. It's not a terrible idea for you to heed the age-old instruction of washing your hands before you eat either.

Another note: If the lines are long and moving fast at a certain vendor, that generally means that the food hasn't been sitting out for prolonged periods of time, making it safer for consumption.

Foods to avoid: Some types of dishes are a hotbed for rampant bacteria. These include cold meat platters, cheese and buffet foods. Opt for smaller fish when ordering out and avoid larger fish or shellfish, as these are more attractive places for microbes to thrive. Cocktail fans will be happy to know most wine, beer and liquor drinks are considered safe to drink, as are coffee and tea (though you might want to avoid including dairy). 

What to do if you get sick
If you find yourself with travelers' diarrhea or other gastrointestinal problems while traveling abroad, trust us, you won't be the first or last to suffer through the symptoms. Keep in mind that pharmacies across the world are very different from those in the U.S. In fact, you can walk into most stores and get the medication you need without a prescription. You just need to describe your symptoms.

Of course, you can always plan ahead and pack medications in case you want to stick with brand names you are familiar with. Before you take any medicine, be sure to check the packaging for damage and tears and never purchase medication from night markets or street vendors.

If you need to see a doctor, it's common practice in most countries to go directly to the clinic or hospital rather than making an appointment like you would in the U.S. You can opt for local hospitals, which will offer quality care but might present language barriers. Many major cities have international hospitals with medical professionals who speak English, though the services might cost more.

When you return home, be sure to set up an appointment with your doctor so you can have blood work done and check your general overall health. A fair warning: If you have been traveling abroad for several months, your body might go through a reverse effect when trying to readjust to American foods.

In short: Your best course of action is to be prepared for anything if you want to eat adventurously. There are many things you can do to prevent falling ill.
