Nutrition expert reveals: Only popular above the clouds – That’s why many people reach for this drink on the plane

Many airline passengers have already pondered this question when they ordered tomato juice "above the clouds" - and wondered why they only drink it "up here in the air."

Let's put it briefly: There's no definitive answer to this question. Although there are no clear facts, several theories and observations are being discussed that, when combined, could explain the popularity of tomato juice on airplanes:

1. Taste changes at altitude: Basic studies have shown that our sense of taste may change in the dry cabin air and lower air pressure on airplanes. Sweet and salty flavors tend to be perceived as less intense, while sour and umami-rich flavors (like those of tomatoes) may be more pronounced. As a result, tomato juice may taste more intense and satisfying on an airplane than on the ground. The big but: taste is entirely individual and subjective. And as the saying goes: There's no accounting for taste. Whether these effects are sufficient to explain the "airplane effect" is more than doubtful.
2. Association and habit: For some people, drinking tomato juice on airplanes is an established habit. Perhaps they tried it once and found it pleasant, or it has stuck in their minds as a typical drink from other passengers or airlines.
3. "Savoriness" as a contrast: Many airplane meals tend to be mild or sweet. The savory, slightly acidic taste of tomato juice can provide a pleasant contrast and enhance the overall taste experience.
4. Psychological effect: The feeling of treating yourself to something "special" or "different" can also play a role. Since tomato juice isn't the most common drink, it may be perceived as a little "time out" on an airplane. Another possible psychological motive is the classic copycat effect, true to the motto: "If he has it, I want it too."

Uwe Knop, born in 1972, is a qualified nutritionist, author, and speaker for lectures at professional associations, companies, and medical training courses.

This is simply because all of the aforementioned reasons only lead to excessive consumption on airplanes. Down on Earth, tomato juice is generally a rather uninteresting beverage—it neither quenches thirst pleasantly nor intoxicates pleasantly nor has a stimulating or activating effect. There are other, better, and tastier drinks for all of these "drinking goals."

No - There is no scientific evidence that tomato juice specifically helps against thrombosis or other specific diseases - neither on the plane, nor on the train, nor while sitting at the kitchen table.

Whether on the plane or on the ground, the following applies to healthy people: Drink when you're thirsty. The most important recommendation for drinks on the plane is quite simple: drink plenty of water . The dry cabin air can lead to dehydration more quickly, which can promote fatigue, headaches, and an increased risk of thrombosis.

Therefore, listen carefully to your body and its thirst signals . If in doubt, if you're not sure whether you're thirsty, simply drink a glass of water—still or sparkling, it doesn't matter. If you prefer juice, spritzer, or other drinks, just drink what you like best .
