Science Explains Why It’s Normal For Plane Food To Taste Bad

Science Explains Why It’s Normal For Plane Food To Taste Bad

Dining experiences on planes aren’t renowned for their quality. The meal served by the air host/hostess may taste bland and dry, but studies have found it has nothing to do with the food or the cooking. Actually, it is all about atmosphere and science – and it’s all about you.

Pressure

A study from The Fraunhofer Institute (a research institute based in Germany) found that the cabin atmosphere, which is pressurized at 8,000 feet, numbed the taste buds. The cool, dry environment causes the meal to be the equivalent of eating food while having a cold. Our perception of saltiness and sweetness, which are vital aspects of the tasting experience, drop by approximately 30% at high altitudes. Meanwhile, the cabin pressure dulls the sensors in the nose that affect taste.

Noise

Another study (this time from Cornell University) found that the noisy environment inside an airplane alters the taste of food. A group of almost fifty people were provided with a variety food to enjoy in a silent setting. They were tested again, this time wearing headsets blasting 85 decibels of noise as a substitute for roaring jet engines on a plane. The tests showed that the noise dulled the sweetness of food, while it intensified the savory aspects. Either way, the tasting sense is compromised. The environment we eat in alters our taste perception. Hearing plays an important role right alongside smell and taste.

Humidity

When reaching soaring heights in a plane, the humidity equals that of a desert (at less than 12%). This dry environment isn’t exactly an ideal dining condition. It explains why a passenger desires that next cup of water or juice after a meal, but also frustrates us as drink servings are much smaller than their on-land counterparts. Taste buds are less effective when they’re dried out.

Flavor

Interestingly enough, not all aspects of taste are relinquished when you board the plane and reach 30,000 feet. Sour, bitter, and spicy flavors are basically unaffected. So, when given the choice between a spicy dish and a sweet dish, one should always choose the former if desiring a flavorsome experience during your flight. Airlines are aware of the altered taste buds, so they will add more salt and sugar to products to enhance their flavor. Anyone focused on health will want to be aware of these additions.

Cooking conditions

While science has explained why plane food tastes so bad, it is also served in trying conditions. It is cooked on the ground, packed, blast-chilled, refrigerated, and heated using a convection oven (dry air is blown all over the food, substituting for a microwave). However, through the study of the science behind taste, airlines are starting to adapt to the conditions and take advantage of the flavors that are enhanced in the air.

What is being done? Science.

  • Singapore has a simulated flight cabin to test the taste of their in-flight food options.
  • Umami, the fifth taste (behind savory, sweet, sour, and bitter) that few know much about, is unaffected by altitude. For example, soy sauce and tomatoes will be utilized more prominently in flights to improve the dining experience.
  • British Airways developed a nasal spray used to clear the nose prior to food consumption. However, it wasn’t popular with passengers.
  • Noise-cancelling headphones are becoming a key tool in altering the perceived environment, blocking out the engine hum. They will also utilize music that improves the taste of certain foods.
  • Some airlines are removing plastic cutlery in the belief that it projects a bad food taste before the passenger brings the meal to their mouth.
  • Quality wine taste is also compromised when hitting high levels of altitude, as liquids expand and contract in such conditions. Low-acid levels are the key, which rules out an in-flight champagne.

Conclusion

With these experiments and potential solutions, it is clear that airlines are doing all they can to research and discover ways to improve the in-flight dining experience. When faced with a lengthy flight, one can either sacrifice their sweet or acidic favorites for a umami option, or deal with the rebellious taste buds dried out in the pressurized environment. Maybe everyone should just fly when they have a cold?

7 Simple Rules to Live by to Get in Shape in Two Weeks

7 Simple Rules to Live by to Get in Shape in Two Weeks

Learning how to get in shape and set goals is important if you’re looking to live a healthier lifestyle and get closer to your goal weight. While this does require changes to your daily routine, you’ll find that you are able to look and feel better in only two weeks.

Over the years, I’ve learned a lot about what it takes to get in shape. Although anyone can cover the basics (eat right and exercise), there are some things that I could only learn through trial and error. Let’s cover some of the most important points for how to get in shape in two weeks.

1. Exercise Daily

It is far easier to make exercise a habit if it is a daily one. If you aren’t exercising at all, I recommend starting by exercising a half hour every day. When you only exercise a couple times per week, it is much easier to turn one day off into three days off, a week off, or a month off.

If you are already used to exercising, switching to three or four times a week to fit your schedule may be preferable, but it is a lot harder to maintain a workout program you don’t do every day.

Be careful to not repeat the same exercise routine each day. If you do an intense ab workout one day, try switching it up to general cardio the next. You can also squeeze in a day of light walking to break up the intensity.

2. Duration Doesn’t Substitute for Intensity

Once you get into the habit of regular exercise, where do you go if you still aren’t reaching your goals? Most people will solve the problem by exercising for longer periods of time, turning forty-minute workouts into two hour stretches. Not only does this drain your time, but it doesn’t work particularly well.

One study shows that “exercising for a whole hour instead of a half does not provide any additional loss in either body weight or fat”[1].

This is great news for both your schedule and your levels of motivation. You’ll likely find it much easier to exercise for 30 minutes a day instead of an hour. In those 30 minutes, do your best to up the intensity to your appropriate edge to get the most out of the time.

3. Acknowledge Your Limits

Many people get frustrated when they plateau in their weight loss or muscle gaining goals as they’re learning how to get in shape. Everyone has an equilibrium and genetic set point where their body wants to remain. This doesn’t mean that you can’t achieve your fitness goals, but don’t be too hard on yourself if you are struggling to lose weight or put on muscle.

Acknowledging a set point doesn’t mean giving up, but it does mean realizing the obstacles you face.

Expect to hit a plateau in your own fitness results[2]. When you expect a plateau, you can manage around it so you can continue your progress at a more realistic rate. When expectations meet reality, you can avoid dietary crashes.

4. Eat Healthy, Not Just Food That Looks Healthy

Know what you eat. Don’t fuss over minutia like whether you’re getting enough Omega 3’s or tryptophan, but be aware of the big things. Look at the foods you eat regularly and figure out whether they are healthy or not. Don’t get fooled by the deceptively healthy snacks just pretending to be good for you.

The basic nutritional advice includes:

  • Eat unprocessed foods
  • Eat more veggies
  • Use meat as a side dish, not a main course
  • Eat whole grains, not refined grains[3]

Eat whole grains when you want to learn how to get in shape.

    5. Watch Out for Travel

    Don’t let a four-day holiday interfere with your attempts when you’re learning how to get in shape. I don’t mean that you need to follow your diet and exercise plan without any excursion, but when you are in the first few weeks, still forming habits, be careful that a week long break doesn’t terminate your progress.

    This is also true of schedule changes that leave you suddenly busy or make it difficult to exercise. Have a backup plan so you can be consistent, at least for the first month when you are forming habits.

    If travel is on your schedule and can’t be avoided, make an exercise plan before you go[4], and make sure to pack exercise clothes and an exercise mat as motivation to keep you on track.

    6. Start Slow

    Ever start an exercise plan by running ten miles and then puking your guts out? Maybe you aren’t that extreme, but burnout is common early on when learning how to get in shape. You have a lifetime to be healthy, so don’t try to go from couch potato to athletic superstar in a week.

    If you are starting a running regime, for example, run less than you can to start. Starting strength training? Work with less weight than you could theoretically lift. Increasing intensity and pushing yourself can come later when your body becomes comfortable with regular exercise.

    7. Be Careful When Choosing a Workout Partner

    Should you have a workout partner? That depends. Workout partners can help you stay motivated and make exercising more fun. But they can also stop you from reaching your goals.

    My suggestion would be to have a workout partner, but when you start to plateau (either in physical ability, weight loss/gain, or overall health) and you haven’t reached your goals, consider mixing things up a bit.

    If you plateau, you may need to make changes to continue improving. In this case it’s important to talk to your workout partner about the changes you want to make, and if they don’t seem motivated to continue, offer a thirty day break where you both try different activities.

    I notice that guys working out together tend to match strength after a brief adjustment phase. Even if both are trying to improve, something seems to stall improvement once they reach a certain point. I found that I was able to lift as much as 30-50% more after taking a short break from my regular workout partner.

    Final Thoughts

    Learning how to get in shape in as little as two weeks sounds daunting, but if you’re motivated and have the time and energy to devote to it, it’s certainly possible.

    Find an exercise routine that works for you, eat healthy, drink lots of water, and watch as the transformation begins.
