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?

8 Things to Watch for If You’re Considering Being Vegetarian

8 Things to Watch for If You’re Considering Being Vegetarian

Vegetarianism has been around for a long time, finding favor with many people, including Pythagoras clear back around 580 B.C. It’s been presented as one of the most healthy diets around, including being touted by the Egyptians to the point of abstaining from meat and animal clothing due to karmic beliefs. The vegetarian society (vegsoc.org) defines vegetarianism as:

“Someone who lives on a diet of grains, pulses, nuts, seeds, vegetables and fruits with, or without, the use of dairy products and eggs. A vegetarian does not eat any meat, poultry, game, fish, shellfish* or by-products of slaughter.”

While it’s pretty obvious that there are multiple benefits to following a vegetarian diet, it’s always good to be informed about the cons of this dietary choice as well.

Outlined below are several things you might want to be aware of before you say good-bye to meat forever. Whether you are a current vegetarian, or contemplating making a shift, keep in mind these 8 things to keep yourself healthy.

1. You could suffer from B12 vitamin deficiency

The B vitamins are especially important for stress management, adrenal health, and brain function. Vegetarians in particularly are at risk for B12 deficiency. Vitamin B12 is attached to the protein in animal products and without enough B12 you can suffer from depression, fatigue, and an inability to concentrate.

Due to its attachment to animal proteins, B12 is the hardest for vegetarians to obtain when they don’t eat dairy or eggs in their diet. This essential little vitamin can be found in some algae and has been added to some yeast, but research doesn’t currently provide enough information to say whether or not these forms of B12 are of good quality and can provide adequate supplementation.

The body is unable to make this vitamin, meaning it has to be taken in through food or supplementation. Essential for making red blood cells, DNA, nerves and various other function in the body, a Harvard Health Medical report in January of 2013 found symptoms of a B12 deficiency can present in sneaky ways including depression, paranoia, delusion, and loss of taste and smell.

2.  You could suffer from higher states of anxiety/depression, lower sense of well-being

According to a CBS Atlanta report, vegetarians suffered from a higher rate of anxiety and depression than their counterparts. Read the full report here. Depression and/or anxiety can be a result of many possible deficiencies including essential vitamins and amino acids you can find only in meat products, including Omega-3s from wild caught salmon.

Without the correct supplementation and proper understanding of diet, including the importance of micro and macro nutrients, depression and anxiety can become a serious problem, bringing down the overall health and well-being of vegetarians.

Even though reports on health and lifestyle show vegetarians have a lower BMI and lower consumption of alcohol and drugs, it also shows they suffer from more chronic illnesses and more visits to the doctor than their meat eating counterparts.

3. You could suffer from excess weight

When you go vegetarian it opens up a lot of food, but just because there isn’t any meat in front of you, it doesn’t mean it’s necessary healthy. Though pizza and beer technically fall under the vegetarian diet, it’s not a healthy choice for your waist line.

Just because being a vegetarian is associated with a healthier lifestyle in many cases, doesn’t mean it’s always true. Making bread and pasta your staples and not understanding where your protein sources should be coming from, can pack on body fat, which increases your chances of health issues such as diabetes and chronic inflammation.

If the choice to go vegetarian happens on a whim without the proper understanding of food control, portion, and nutritionally dense alternatives you can find yourself reaching for vegetarian foods, which could cause serious problems down the road. Nuts are a good example, but just because something is touted as healthy, it doesn’t mean, your should eat it in excess.

Eating too many calories in fat will still cause you to gain weight. Eating too many calories in carbs will cause you to gain weight. Eating too many calories in protein will cause you to gain weight. See a pattern here? Not to mention you’ll miss out on important nutrients the body needs by over-eating in one area and under-eating in another. Re-read number 2.

4. You could have a higher risk of heart disease

Eating plenty of fruits and vegetables should be a goal we all strive for, but when you cut out meat, you also cut out what is known as complete protein, which you find in animal by-products. Complete means more than just the essential amino acids, it means those amino acids contain dietary sulfur. Without enough dietary sulfur, which is found almost exclusively in fish and pasture feed grass beef, the body will struggle with the biological activities of both protein and enzymes.

The effects cascade downward, effecting bones, joints, tissues, and even metabolic issues. In short, a low intake of sulfur associated with a vegetarian diet can result in high blood levels of homocysteine, which may lead to blood clots in your arteries, blood clots raise your risk of stroke and heart attack.

5. You could suffer from low cholesterol

I know, at first you’re thinking, wait, low cholesterol is a good thing. Yes, it is, when it’s LDL cholesterol, which you get from eating an unhealthy diet, but low HDL (good cholesterol) can cause serious health issues. HDL, according to the mayo clinic, is in every cell in our body and can help fend off heart disease, not enough of it though, and too much LDL can go the other way, will be building up plaque in the arteries and leading to heart disease.

Cholesterol, the good kind, is actually vitally important to the making of every steroid hormone in the body! There are six, and without cholesterol the body is unable to convert hormones, and it can cause damage in the endocrine system.

A vegetarian without a balanced diet, meaning enough protein, enough veggies, and enough good fats, could disrupt his or her adrenals, which are directly connected to the endocrine system and the body’s ability to make and synthesize the hormones your body needs. The six major hormones in the body help do everything from metabolizing carbohydrates, to the electrolyte balance, to making sure if you’re a woman you can carry a healthy baby through pregnancy.

6. You could suffer from lower bone density and osteoporosis.

Osteoporosis, the disease where the bones get thinner, weaker, and fractures become a high risk with day to day movements. It’s often associated with the older generation, but your risk for osteoporosis increases with a lower bone density. Bone density can be directly related to diet and lifestyle, along with many other factors.

When it comes to eating a vegetarian diet it’s possible to miss getting enough of the right nutrients, causing the bones to begin to break down. If your vegetarian diet isn’t balanced and providing you with the correct nutrients and the means to absorb the correct nutrients, your body could begin to break down.

Recently, Professor Tuan Nguyen of Sydney’s Garvan Institute of Medical Research led a review of both Australian and Vietnamese research around the bone density of vegetarian versus their meat eating counterparts. Helping Professor Nguyen was Dr. Ho-Pham Thuc Lan from Pham Ngoc Thac University of Medicine in Vietnam. The review was designed to sort though years of research surrounded by discrepancies and inadequate clinical data.

At the end of the review, with vegetarianism rising to around 5% of the populace in the western continents, and with wide spread osteoporosis reports – 2 million in Australia and closer to 54 million in America – the decrease in bone density of vegetarians is a serious issue which needs to be addressed, if you’ve cut meat and animal by-products out of your life.

7. You could be at a higher risk for colorectal cancer

Cancer seems to be running rampant through America, and it’s within everyone’s best interest to do all they can to keep their body healthy and happy to prevent cancer from finding a place to grow. In most studies it’s been found vegetarians are at lower risk for cancer, but a European Oxford study with over 63 thousand men and women in the United Kingdom found the risk for colorectal cancer higher in vegetarians than in meat-eaters.

Extra care needs to be taken when establishing a diet to ensure the body is receiving and able to up take all the important nutritional benefits and requirements from food.

8. You could end up eating more processed food

Depending on how deep you choose to go as a vegetarian, it could create the need to substitute a lot of food and recipe ingredients in your diet, but what happens when you cut out meat, eggs, and dairy and your recipe calls for meat, eggs, and/or dairy? You have to end up using a “healthy” vegetarian alternative which include stabilizers, thickeners, and various other ingredients you can’t pronounce.

Lauren from Empowered Substance puts it into a great perspective with her comparison of Earth Balance, a vegetarian approved butter replacement compared to butter. She points out the ingredients in Earth Balance consist of: Palm fruit oil, canola oil, safflower oil, flax oil, olive oil, salt, natural flavor, pea protein, sunflower lecithin, lactic acid, annatto color. Meanwhile, the ingredient list in butter, is much shorter. It’s butter.

That’s only one example. To appeal to the vegetarian lifestyle food manufacturers have found alternatives which fall under vegetarian, but aren’t necessarily healthy for you. Consider baked goods, which though vegetarian can be filled with more sugars and binders than regular baked goods with diary products. It’s the same with vegetarian items like mac and cheese, without using real cheese you may just be getting oil and thickeners, without even the smallest amount of nutritional value.

The reality is, most vegetarian substitutes contain the same junky alternatives which even meat eaters should be avoiding to remain happy and healthy.

On one final note, whichever lifestyle you choose to work with, remember anything in excess – including protein and animal by products – isn’t healthy for the body. It takes a wide spectrum of food and nutrients to keep the beautiful body you travel around in all day running in prime condition.
