Blood Sugar Control on Flights: T1D Dietitian Tips

Feb 03, 2025

Traveling with diabetes, whether it’s Type 1 (T1D) or Type 2 (T2D), can come with a unique set of challenges

Especially when it comes to managing blood sugar levels while eating outside of your usual environment. A diabetes dietitian or diabetes educator can help provide strategies for controlling your blood sugar, even while navigating unfamiliar airline meals. In this post, we’ll break down how to manage meals during flights and ensure that your blood sugar remains stable while traveling.

1. Understand the Meal: Be Prepared

When choosing between meal options, it’s important to consider how each will impact your blood sugar. For example, a pasta meal can cause a prolonged spike in blood sugar due to its high carbohydrate content. A T1D dietitian or T2D dietitian will recommend meals rich in protein, such as chicken, to maintain better blood sugar control. Without clear carb counts or nutrition information, opting for lean proteins and avoiding high-carb meals can help prevent blood sugar spikes and ensure better control throughout your flight.

2. Portion Control and Carb Counting

Even if you choose a seemingly healthy meal, such as chicken and rice, estimating your carbohydrate intake is crucial. A diabetes dietitian will emphasize the importance of understanding portion sizes—like estimating half a cup of rice at 20-30 grams of carbs. Accurately estimating carbs allows for proper insulin management and medication adjustments, helping keep blood sugar stable during the flight. Whether you’re working with a T1D dietitian or a T2D dietitian, carb counting is a vital part of your diabetes management plan.

3. Supplementing Your Meal

Airline meals might not provide enough protein or vegetables, which is why it's essential to bring along extra snacks. A T1D dietitian or T2D dietitian will encourage you to pack high-protein snacks, such as turkey sticks, nuts, or a protein bar, to complement your meal. These snacks can help balance out your carb intake and prevent blood sugar spikes or crashes, ensuring you stay energized and maintain stable blood sugar levels throughout the flight.

5. Plan for Success

The key to managing blood sugar during travel is preparation. Airline meals might not always meet your nutritional needs, so it’s important to plan by bringing your snacks that you know will help maintain stable blood sugar. A diabetes dietitian, whether specializing in Type 1 or Type 2 diabetes, can help you create a travel-friendly plan that includes the right balance of protein and carbs. With the right preparation, you can enjoy your trip without worrying about blood sugar fluctuations.

Traveling with diabetes doesn’t have to disrupt your blood sugar goals. With the help of a diabetes educator or a T1D/T2D dietitian, you can navigate airplane meals with confidence and enjoy your travels while keeping your blood sugar in check.

If you’ve faced challenges eating on international flights, a diabetes dietitian is there to provide guidance and support for your travel and diabetes management needs.
