1. Try to eat the same (or similar) foods you eat at home.
As tempting as it might be to indulge at rest stop eateries, your digestive system may not be happy with this choice. By being on the road, your body is already in a different environment, so you'll want to avoid any unnecessary stressors to your system - unless you're fine with stopping at multiple rest stops due to poor food choices. If your body is not used to eating chocolate at 10 am, for example, don't buy that candy bar just because it's available.
Once you've reached your destination, continue to respect your system by easing into trying new foods. I know that eggs are a safe bet for me, so I had that at the diner Sunday morning. I wisely chose not to have a milkshake - even though it looked delicious - because I just didn't know how I would react to it, since I don't have milkshakes at home. When you do decide to eat away from your norm, make sure you are near a bathroom for 30 minutes after your meal - just in case.
2. Bring your own food.
Not only will this save you money, you'll have control over the ingredients, and you'll avoid any negative consequences of being hungry but unable to stop because the next rest stop is 40 miles away. I made a huge chicken salad that the BF and I shared for lunch, and we brought string cheese, tankabars and epic bars, and I brought cans of sardines for myself so I can get a good source of healthy fat. I wish I had thought to also pack grapes and carrots for that first day's drive - the food I brought definitely lacked crunch - so I made sure to get some for the next leg of the trip. But refer back to the first tip - if you don't usually eat 1/2 a pound of grapes in one day, for example, and you do that on the road, don't be surprised if your digestive system becomes unhappy.
3. Watch your fiber intake.
Buying grapes, carrots, and Terra chips was a huge help for the 2nd leg of the trip - it felt great to have real food to eat on the road, and fiber definitely can help you stay regular. But I neglected to remember what eating A LOT of fiber-rich foods can cause: flatulence. The fix? Make sure you also add some protein and healthy fats to your snacks. The balance of macro-nutrients will help ease any flatulence issues, and it will also keep you satiated and focused for your drive.
One thing that made a huge difference for me was to continue to take probiotics. I have found the probiotics keep my digestive system consistent. Full disclosure: I often become constipated on road trips that last for more than a few hours. There's something about sitting in a car for numerous hours that my digestive system just doesn't like. But on this road trip, I increased my probiotic intake, and that, along with the first two tips, has helped keep me regular. So, if you aren't taking a probiotic yet, go start - but make sure you begin at least a few weeks before your trip so your system can acclimate.
5. Stay hydrated - drink water.
It can be tempting to drink coffee, soda, or energy drinks while on the road, but it definitely won't be kind to your digestive system! Hydration is crucial to preventing constipation, so bring that water bottle! Caffeinated drinks often cause dehydration, so try to limit your intake to one cup in the morning if you must have a little caffeine to avoid withdrawal.
Bonus tip: Already constipated? Try walking around.
Sitting for long periods of time can affect the flow of the digestive system. Moving the body, such as exercising regularly, also keeps the digestive system regular. But it's quite difficult to exercise when spending the day in the car. The fix: when taking breaks at rest stops, devote some extra time to walking around. Even a 10 minute walk every 2-3 hours can help relieve constipation.
