Eating Your Way Through the World with Type 1 Diabetes: Real Talk from Someone Who's Done It

I've eaten my way through more than forty countries with Type 1 diabetes. I've stood in front of Bangkok night markets with no clue what anything was, worked my way through seven-course tasting menus in Italy with zero carb counts in sight, and somehow made it through a two-week road trip across the American South — where sugar isn't a condiment, it's practically a food group. And through all of it, I've kept my blood sugar reasonably in check.

"Reasonably" is doing some heavy lifting in that sentence, and I mean it honestly. Eating abroad with diabetes is never a clean, predictable experience. You will miscalculate. You'll get a surprise spike from that rice dish you were certain would be fine. And there will be that one stomach-dropping moment — sitting at a restaurant somewhere remote, CGM alarming, realizing your glucose tabs are back at the hotel.

I've been there. More than once.

But here's what I know after twenty-plus years of traveling with Type 1: the joy of eating your way through a new place is absolutely worth it. Food is how you understand where you are.

And diabetes, once you stop fighting it and start working with it, doesn't have to hold you back from any of it.

Here's what I've actually learned about eating abroad with diabetes — through trial, error, and a whole lot of miscalculated meals.

The carb count is never what you think it is

Nobody warns you about this clearly enough before your first big trip with diabetes. The same dish, prepared in a different country, can hit your blood sugar in a completely different way:

Pasta in Italy is typically cooked al dente, which digests more slowly and causes a gentler blood sugar rise than the softer versions you might be used to at home.

Japanese white rice spikes me faster than almost anything else I eat. I've learned to dose conservatively and correct later.

Mexican beans? Slower than you'd ever expect — a pleasant surprise, honestly.

Indian dal depends entirely on the type of lentils, the cooking time, and whether it's been made with ghee. Same name, wildly different results.

None of this means you should avoid these foods. It means you should approach them with curiosity instead of fear.

💡 My #1 rule when eating abroad: start with a slightly conservative insulin dose, eat, and watch. I'd rather deal with a mild high a couple hours later than go low in a restaurant where no one speaks English.

Do your food research before you land — not when you're hungry

I always carve out an hour before any new trip to research the local food landscape. Not to restrict myself — to arrive prepared. I want to know:

What are the main carbohydrate staples in this country's cuisine?

Is the local bread dense and hearty, or light and airy?

Does the food culture add sugar to savory dishes? (It does, frequently, throughout Southeast Asia — and in more American regional cooking than people realize.)

Are portion sizes massive (hello, Texas) or more modest?

The ADA (American Diabetes Association) travel resources are a good starting point for general principles. But honestly, the most useful research I've done comes from online diabetes communities and forums — places where real people share real blood sugar outcomes from eating specific dishes in specific countries.

Type 1 forums in particular are full of travelers who've road-tested everything from pho in Hanoi to injera in Addis Ababa.

Arriving in Japan already knowing that ramen broth often has hidden sugars — and that tonkotsu and miso ramen will behave differently on your CGM — means you're not starting from zero at every meal.

Always carry fast-acting carbs. No exceptions.

This sounds obvious. And yet.

When you're abroad, it's easy to get comfortable. The vacation mindset kicks in, you're doing way more walking than usual, eating at unpredictable hours — and somehow your glucose tabs end up sitting on the nightstand back at the hotel. I've done it. Once. One time was enough.

Now I keep glucose tabs in every bag, every jacket pocket, and every daypack I travel with. When I'm abroad, I double my usual supply — because I know I'll be more active than usual, my eating schedule will be all over the place, and I will almost certainly miscalculate at least one meal.

Local options exist almost everywhere — fruit juice, soda, candy — but in an actual hypoglycemic episode, you want something familiar, in a dose you can measure, that you know works for you. Don't rely on finding a corner store at the exact right moment.

Getting through restaurant meals when language is a barrier

This is where I've had to get creative over the years. A few things that genuinely work:

✅ Learn a handful of words in the local language. "No sugar," "without sauce," and "what's in this?" will take you further than you'd think. Google Translate's camera function — where you just point your phone at a menu and get an instant translation — has become completely indispensable for me. It's not perfect, but it's transformed the experience of eating somewhere I can't read the alphabet.

✅ Ask for sauces on the side. Restaurant sauces are often where the hidden sugars hide, especially in Asian cuisines and a lot of American regional cooking. Getting them on the side lets you control how much you add — or skip them entirely.

✅ Don't be afraid to eat simply. Some of my most diabetes-friendly meals while traveling have been the most straightforward: grilled fish and vegetables in Greece, a mezze spread in Lebanon, a plain rice bowl with pickled vegetables in Japan. Eating safely doesn't mean eating boringly.

✅ Talk to the restaurant. This works better than most people expect. Locally-owned restaurants — the ones actually cooking from scratch — are usually happy to tell you what's in a dish, adjust a preparation, or point out the sweeter items on the menu. Chain restaurants are harder, since they're working from standardized recipes they can't modify.

Buffets, street food, and the beautiful unknown of food when traveling

Buffets are simultaneously a diabetic's dream and a diabetic's nightmare.

• The dream: you can see everything, choose exactly what you want, go back for extra protein and skip the second scoop of white rice.
• The nightmare: portions are limitless, it's incredibly easy to eat more than you planned, and you've got fifteen dishes to estimate at once instead of one.

💡My buffet rule: I plate everything before I inject my bolus insulin. I decide what I'm eating first, then dose. It sounds simple, but it genuinely changed everything for me.

Street food is a different animal — it's improvisational by nature, and I love it. I eat it, I enjoy it, and I accept that my blood sugar will probably do something unexpected. A small correction dose later is not a failure. It's just the cost of eating a perfect fish taco on a beach in Baja, or a steaming bowl of pho from a cart in Vietnam.

Heat, alcohol, and the things that complicate everything when traveling

Two factors affect blood sugar abroad more than almost any specific food: heat and alcohol.

Heat increases insulin absorption significantly. In very hot climates — I've spent weeks managing this in Morocco, Thailand, and Sri Lanka — insulin works faster, lasts for less time, and your sensitivity can shift dramatically from one day to the next. I typically reduce my basal slightly in the first few days of a hot-climate trip and pay close attention to my overnight numbers.

Alcohol, particularly wine and spirits, can cause delayed hypoglycemia hours after drinking — often while you're asleep. Abroad, where you're more likely to be drinking with meals, staying up later, and sleeping in an unfamiliar environment, this is a real risk. I always eat a full meal alongside any alcohol, never drink on an empty stomach, and run a slightly higher blood glucose target overnight when I've had wine with dinner. A bigger-than-usual pre-bed snack is often a smart precaution.

Your medication has to travel as well as you do

All the meal planning in the world only works if your insulin — or your Ozempic, Mounjaro, or other injectable medication — is actually viable when you need it.

Insulin that's been sitting in a hot rental car, packed in checked luggage in an unheated cargo hold, or stored in a hotel mini-fridge that swings wildly in temperature is insulin you can't rely on. And when you're far from home and far from a pharmacy you know, that's a genuinely scary situation.

After years of improvising with wet cloths, lunch bags, hotel ice buckets, and crossed fingers, investing in a medical travel cooler was the single biggest improvement I made to how I travel. My medication arrives in exactly the same condition it left in, every time — whether I'm on a ten-hour flight or a long day of sightseeing in 95-degree heat.

Eating abroad is one of the great joys of travel — full stop

I want to end here, because I think it matters.

Managing diabetes abroad is genuinely more complicated than managing it at home. The food is less predictable, there are sometimes no nutrition labels, your schedule goes out the window, and some days you'll get it completely wrong. That's not a failure of your diabetes management. That's just travel.

The question isn't whether you can eat freely abroad with Type 1. The question is whether you have the right tools, the right knowledge, and the right mindset going in.

I've eaten tagliatelle in Bologna and pad thai in Chiang Mai. I've had mezze in Beirut and jerk chicken in Kingston. I've had unexpected highs and lows that came out of nowhere.

And I have never once wished I'd stayed home.
