Right, we know what you're thinking. Really? A sweet potato? That's exactly the glances and vibes we got from our fellow passengers as we unwrapped it and took our first bite. People looked at us like we were the strangest fellow they'd seen in a long time, yet, meanwhile, the guy two rows up who was scarfing down a pungent Big Mac didn't even get a second look.
In our tried-and-true opinion, one of the biggest mistakes travelers make lies within their dietary choices before and during flights. Foods high in fat, sodium, and sugar are absolutely devastating to your stamina on the road. Because your body is already going through stress and dehydration due to the altitude, the worst thing you can do is feed it junk. Yet, we see it all the time: Burgers, fries, chips, candy, soda. It's a direct path to a lack of energy on the road, and this is why, despite being a "weirdo," we ended up getting the last laugh with our sweet potato lunch.
Now, remember, don't bring anything to eat that is aromatic, but consider throwing public perception to the wind and getting creative with your in-flight meals. We always pack up whatever fruit and veggies we have in the fridge (broccoli, sliced tomato, carrots, avocado, bananas, apples) and try to keep a pack of almonds or unsalted peanuts in our carry on. Once in awhile, something "weird" makes it in there, but as long as it's nutritious, the joke's on those eating Mickey D's. Without question, you will feel the difference in your body's response upon landing a few hours later.
And, if nothing else, we found chowing down on a sweet potato to be a pretty good icebreaker.
