regularize a repast in anyfast - foodrestaurant , and you ’ll likely take the air away with a sandwich , fries and a boozing . If you had to key the component of this meal , you might heel beef ( or chicken),lettuce , tomato , cheeseflower , tomato ketchup , bread , white potato and soda . Not complicated , correct ? incorrect .

Burger and poulet joints do n’t think of the building blocks of a fare point as constituent . They think of them as components , which are made of ingredients . For example , McDonald’sfamous Big Mac jingle – " two all beef patty , special sauce , lettuce , tall mallow , pickles , onions on a sesame germ bun " – suggests the sandwich has seven components . Would you consider it has 67 factor ?

clear , fastfoodis more complicated than it look . Many menu items control processed foods , which have been modify from their natural state for safety or convenience . Processed foods tend to have multiple additive to keep them fresher longer . Across an full fast - food carte , there are 1000 of ingredients , ranging from the commonplace ( body of water ) to the alien ( xanthan gum ) .

Considering that some of these ingredients have been implicated in serious health consequence , it would be serious to cognize which are the most rough-cut . We ’ve put out to respond that very interrogative . We start with menus from five popular degraded - nutrient chain – McDonald ’s , Burger King , Taco Bell , KFC and Arby ’s – did some tallying , then cross - match our findings with the U.S. Food and Drug Administration ’s lean of common solid food constituent and colors . The result is the top 10 most common ingredients in immobile food , organize by the eccentric of ingredient and what it does .

Up first is the most common preservative .

10. Citric Acid: The Most Common Preservative

Salthas been used for centuries to preserve meats and Pisces the Fishes . It works to stamp down the growth of bacteria cells , which recede water and become desiccate in salty environments . Over the year , nutrient scientist and manufacturer have discovered that other chemicals also can serve as preservatives .

Citric acid , an constitutional window pane found in many fruits , especially caustic lime , lemons , and grapefruits , is one of those chemical substance . It increase the acidulousness of a bug ’s environs , making it harder for bacteria and mold to hold out and regurgitate . It can also be used to bind to and neutralize productive - degrading alloy ions that get into food via processing machinery .

What ’s neat about citric Zen is that it does all of this without harming the organisms that ingest it . It occurs naturally in all living things and is an significant intermediate chemical in a metabolic nerve tract get it on as the citric acid cycle , orKrebs cycle . As a result , citric acid does n’t have side effects in 99.9 pct of the population and is okay by the U.S. Food and Drug Administration for use in solid food and drinkable [ generator : Driver ] . Maybe that ’s why the chemical substance appear 288 clock time on thefast - foodmenus we surveyed .

The next item on our list –high - fructose corn syrup– does n’t fare as well in the court of public opinion .

9. High-fructose Corn Syrup: The Most Common Sweetener

Fast - foodrestaurants have many different ways to sweeten beverages , baked goods and condiments . Sucrose , orsugar , reigned as the traditional hook for years until solid food scientists start to synthesizesugar substitute . Saccharin arrive first , followed by aspartame and sucralose .

A more significant revolution came in 1957 when two scientists work out a process to manufacturehigh - fructose corn syrup(HFCS ) . Since then , HFCS has evolved into the sweetener of choice , find its direction into a myriad of foods and drinkable . In our survey of riotous - food for thought menus , the chemical appeared as the first ingredient almost twice as much as sugar .

So what is it and why is it controversial ? The unconscious process to make hydrofluorocarbon involves changing one simple loot – glucose – in cornstarch to another simple sugar do it as fructose . The product , a compounding of the two simple sugar , is just as sweet as sucrose , but much cheaper to process . It also pretend as a preservative , offer the shelf life of food . No marvel it ’s one of the most ubiquitous ingredients in fast food .

Unfortunately , some inquiry has shown a link between HFC and obesity . At the very least , many beverages and work foods made with this corn - derive lure are gamy incaloriesand low in nutritionary value .

Color additive , like the one we ’re about to cover , also have bad reputations .

8. Caramel Color: The Most Common Color Additive

When it come to the psychology of eating , food has to depend good if it ’s going to taste good . That ’s whyfast foodscontain vividness additives – to prevent the loss of a food for thought ’s inherent semblance , to enhance color or to add together color when it does n’t survive of course . Hardly a individual quick - solid food computer menu item does n’t have at least one contrived color buried somewhere in its constituent list .

plebeian additive admit Yellow No . 5 , Yellow No . 6 and Red No . 40 . accord to one source , Red No . 40 , which recover its way into gelatin , pastry dough and those Ne - blood-red maraschino cherries perched atop your Chick - fil - A handclasp , is the most widely used nutrient dyestuff in America . This same source says Yellow Nos . 5 and 6 , which provide the favourable glow tocheeses , pudding and Proto-Indo European filling , and soft drinks , are the second and third most plebeian intellectual nourishment colouring , respectively [ source : Women ’s Health ] . But when we analyse the element of five pop riotous - intellectual nourishment menus , we found caramel brown color to be even more unwashed .

Caramel people of colour is the benighted brown cloth that results from carefully heating food - form saccharide . Just imagine of the color of sautéed onion plant ( a process fuck as caramelizing , by the way ) , and you ’ll get a good theme of this particular hue , although it can range from reddish - brown to light yellow . adverse to what you might guess , caramel color has no meaning burden on the flavor visibility of the ruined product .

The same ca n’t be said of the next point on the lean .

7. Salt: The Most Common Flavor or Spice

In terms of oftenness , salt– or sodium chloride – appeared more time on the firm - solid food menus we surveyed than any other ingredient . It ’s not always first , but it ’s always there , even in sweetfoods(shakes and sundaes , for example ) that do n’t seem piquant at all .

libertine - solid food chains use salinity primarily to make their meal more toothsome . It ’s paired with capsicum pepper plant to season hamburgers , and it ’s a major constituent in bread , ham , Francis Bacon , sausages andcheese . A exclusive gash of American cheese , in fact , hold 250 milligram of sodium . That makes a double cheeseburger , a popular riotous - food point , peculiarly piquant . TheMcDonald’sversion of this favorite contains 1,150 milligram ( 1.15 Hans C. J. Gram ) of sodium [ source : McDonald ’s USA Nutrition fact ] .

Most health experts warn against eating too much salt , channelize to studies that show a link between sodium andhigh parentage pressure . The regime recommends a utmost of 6 gm of salt per mean solar day for adults , 5 g a day for nestling between ages 7 and 10 , and 3 grams for children between 4 and 6 . Compare that good word to a distinctive family repast from KFC , which delivers a banging 5.2 grams of salt per person [ reservoir : BBC News ] !

Even if you cut down your salt inspiration , you have to be on the lookout for other root of sodium . Our next ingredient is a premier instance .

6. Monosodium Glutamate: The Most Common Flavor Enhancer

Monosodium glutamate , orMSG , earned its reputation in Asian takeout food kitchens across America , but almost allfast - foodrestaurants use the tone enhancer to some extent . Interestingly , MSG has no trenchant taste itself . or else , it overstate other flavour , especially in food with crybaby or boeuf flavoring , through processes that scientists do n’t fully understand .

MSG is the sodium salinity of the amino dose glutamic acid and is just one anatomy of glutamate , a chemical that exists course in many living thing . In fact , Asians historically used a broth made from seaweed as their source of MSG . Today , the solid food manufacture find the white gunpowder through a fermenting process take carbohydrates such as starch , cabbage beets , sugarcane or molasses .

No such building complex is associated with the next ingredient on our inclination .

5. Niacin: The Most Common Nutrient

It seems unknown that riotous - food for thought chains would tot up nutrients to our spare - value meals . Does n’t food already come with a natural supply of nutrients?Broccoli , for case , contains significant levels of many essential vitamin and mineral , includingvitamins C , KandA. Of naturally , broccoli is n’t by and large found on afast - foodmenu . In the space of sweet yield and vegetables are scores of extremely processed foods . manufacture these foods often has the unwanted side effect of eliminating key vitamins and minerals , which then have to be replaced in a process known asenrichment . Fortificationis the companion process , which adds nutrients that may be lacking in the diet .

wheat berry flour is one of the most common processed detail in the world of fast food . It is used to make unvarnished buns , sesame germ buns , corn - dusted backside and specialty buns of all shape and sizing . The wheat flour line up in all of these bread Cartesian product has been enriched with several vitamin and minerals , includingriboflavin , folic acidandiron . But the most commonly added nutrient isniacin , or vitamin B3 . Niacin is water - soluble and incessantly eliminated from the eubstance through urine . That signify you need a continuous supplying of the vitamin in your dieting . But you do n’t need to eat bread merchandise to get your recommended daily allowance . Poultry , fish , thin nub , orchis and ball also hold plenty of niacin .

Up next is another ingredient that delight widespread role in fast - food fare .

4. Soybean Oil: The Most Common Oil or Fat

push back around America long enough , and you ’re bound to see asoybeanfarm . According to the U.S. Department of Agriculture , nigh 75 million acres ( 30 million hectares ) of farmland were used in 2008 to rise Glycine max , resulting in 2.9 billion bushels of craw [ source : U.S. Soybean Industry Statistics ] .

What happen to all of those soybeans ? Many are jam and motley with solvents to pull up soja bean oil – a fast - food staple used for bass - frying and as a key constituent in margarine , pastries , cookies , crackers , soups and nondairy creamer . Some ingredient lean identify it as soybean oil colour , others as vegetable oil .

soy oil contains several unsaturated fatty acids , which signify their component molecules have fewer hydrogen atom . regrettably , unsaturated fats do n’t have long shelf life . Hydrogenation , or forcing hydrogen flatulence into soja fossil oil under passing high pressure , eliminates this undesirable characteristic . But it also leads to the foundation of trans fatty acids , which have been link toheart disease .

scientist have of late produce kind of soy that produce oils low in unsaturated fats . As a result , this new and improved oil does n’t call for hydrogenation . Fast - food restaurants are slowly squeeze trans - fat - free soybean oil , although hydrogenate fossil oil is still widely used .

Food central processor also expend soybean oil as a start point for other additive , include the two tight related ingredients we ’re about to cover .

3. Mono- and Diglycerides: The Most Common Emulsifiers

James Cook and food preparers have been working withemulsions– two or more liquid that ca n’t normally be ruffle together – for a long time . Fortunately for ourtastebuds , they ’ve discovered several nub that encourage liquids to overcome their unwillingness to unite . These sum are known asemulsifiers .

Egg is commonly used as an emulsifier , but most food manufacturer today use glycerides obtained from palm oil , soybean oil , sunflower oil or tallow . veggie petroleum and animalfatcontain mostly triglyceride , but enzymes can be used to break down triglycerides into mono- and diglycerides . These are the ingredients you see so frequently on fast - food menus .

Mono- and diglycerides allow quiet mixing of fixings , prevent breakup and generally stabilize food . you’re able to find them in ice cream , margarine , scorched goods , whipped topping and certain beverages . Luckily , glycerides pose no serious health threats , although they are a generator of fat . The U.S. Food and Drug Administration has classify them as a " generally recognize as secure " substance , indicating that expert consider them secure as food for thought additives .

Next up , we have one of the most versatile ingredients in all of profligate food for thought .

2. Xanthan Gum: The Most Common Stabilizer or Thickener

In the fifties , a chemist work for the U.S. Department of Agriculture began behave research on an interesting new molecule . The pharmacist was Allene Rosaline Jeanes , and the molecule wasdextran , a elephantine atom made of thousands ofsugarbuilding blocks . Jeanes had gravid trouble finding big quantities of dextran until a flaccid drink company came to her with a bottleful filled , not with refreshing root beer , but with something slimy and viscous . Jeanes discover that the bottle had become foul with a bacteria that produced dextran as a byproduct of fermentation . She set apart the bacteria cells and suddenly had a mechanics to produce all of the dextran she needed .

Jeanes also distinguish another similar molecule that would become known asxanthan chewing gum . Also produced by a bacterium –Xanthomonas campestris– xanthan gum is widely used by the food industry as a thickening agent . It ’s especially useful in salad dressing to help keep constituent likeoilandvinegarfrom separating . Xanthan gum is not an emulsifier , however . It works by brace emulsion , increase the viscosity of the mixture so that the oil and acetum stay together longer and so that spiciness stay set aside .

Xanthan gum also creates a smooth , pleasant texture in many foods . For this reason , it appears inice pick , whipped topping , custard and pie filling . And the really good news show : It ’s not associated with any known adverse effects .

Our final ingredient is not as exotic as xanthan gum , but it rules the roost when it comes to riotous intellectual nourishment .

1. Chicken: The Most Common Meat Product

The future , however , is chicken . McDonald ’s 2007 leverage of poulet were up 59 per centum from 2003 , while its beef leverage were up just 10 percent over the same period [ source : Hughlett ] . Numbers from the U.S. Department of Agriculture hold this out : Chicken pulmonary tuberculosis more than doubled between 1970 and 2004 , from 27.4 pounds ( 12.4 kg ) per individual to 59.2 pound ( 26.9 kilograms ) [ seed : Buzby ] . Most of this growth can be hunt to libertine - nutrient chains , where people like us ill-use up to the registry and club fried or grill chicken – and a hundred other element that transform farm - fresh fowl into the quick - food Gallus gallus that we detest to love .

If you ’re not running out now to get some volaille mixed with citric dot and xanthan gum , keep reading for more fast - food knowledge .
