Dietitians offer 5 tips for healthier long flights

A Korea Times travel guide published Saturday summarized five dietitian-backed steps for staying healthier during long flights, citing advice from EatingWell.

The guidance focuses on common travel strains, including fatigue, dehydration and sitting in one position for extended periods, according to The Korea Times.

The Korea Times reported that long flights can leave travelers fatigued, dehydrated and seated in the same position for extended periods. The article cited EatingWell, which offered five tips based on dietitians’ advice.

Registered dietitian Megan Ormsby said one of the best habits for flying is to “maintain sufficient energy from before boarding until the end of the trip,” according to The Korea Times.

Dietitian Bonnie Taub-Dix advised eating before boarding, with a meal that includes protein, dietary fiber and healthy fats, the report said. The Korea Times also reported that most solid processed foods can pass airport security screening, while foods containing liquids may face restrictions.

On international flights, liquids such as water and coffee generally must be in containers of 100 milliliters or less to clear security, according to the report. The article said low humidity in airplane cabins can make the body lose water more easily.

“Don't wait until you're thirsty to drink. You should stay hydrated consistently throughout the flight,” Ormsby said, according to The Korea Times.

The report also advised passengers to get up once every hour or two if possible, while following seat belt signs and cabin crew instructions.

The Korea Times said the article was translated by a generative AI system and edited by the publication.
