The Chemistry Behind Diet Soda

The Chemistry Behind Diet Soda
Everyone who knows me knows that my favorite soft drink is Dr. Pepper. There was a time when I drank Dr. Pepper with all my meals, I also realized during that time that I was feeling heavier than before, and I gained weight as well; I needed to make a change. I did what a lot of people in America do while trying to give up soda, I gave up the regular Dr. Pepper and switch to the Diet Dr. Pepper mainly because it contained zero calories. When I tried it I hated it, it tasted so fake and was not something I wanted to taste ever again. So I wanted to know, what’s really inside the diet sodas? How does drinking diet soda really affect me and society? Does diet sodas benefit or harms this society that is overwhelmed with artificially sweetened beverages? In this essay I will be talking about the chemistry of diet sodas and the effect it has on the body.
In a culture that is overwhelmed with consuming soda, when trying to lose weight, the easiest way people try to stop drinking soda is switching to diet soda. For example, one can of non diet Coke contains one hundred and fifty calories per twelve fluid ounces, whereas a can of Diet Coke has zero calories per twelve fluid ounces. It sounds convenient to make the switch because of the difference in calories, on the other hand is switching to diet soda really as helpful as it sounds? Some studies have shown that diet soda is not a beneficial source f0r wanting to lose weight for it is dangerous and risky. An article that was done by Harvard Health said that “people who drank diet sodas daily were at a higher risk for vascular events, such as heart attack and stroke, compared to those who drank fewer diet sodas or even those who drank regular sugar-sweetened sodas.” (Do you really need that diet soda? 2012)
In a study done by the Journal of General Internal Medicine, people who drink diet sodas may also be consuming other solid foods and drinks that contain lots of sweets but empty calories. This study also showed that consuming diet beverages can “condition the human taste buds to crave very sweet foods” (Dr. Eric Rimm). In a research data obtained by the American Journal of Public Health, Sara N. Bleich examined the national patterns in adult diet-beverage consumption and caloric intake. This research found that “individuals who drink diet beverages typically have a higher body mass index (BMI) intake from snack food, and among heavier adults do not eat fewer calories than those who consume sugar-sweetened beverages” (Diet-Beverage consumption and caloric intake among US adults 2014).
The methods that were used for this research was a twenty four hour analysis dietary recall on adults aged twenty years old or older with exclusion of survey respondents that were pregnant or had diabetes. The research found that although adults that consumed sugar-sweetened beverages had a higher intake of calories, the difference was only significant for healthy-weight adults. For those adults consuming diet beverages and were overweight or obese, the calories intake were higher from solid food consumption. To sum it all up, the research concluded that “overweight and obese adults drink more diet beverages than healthy-weight adults and consume significantly more solid-food calories and a comparable total calories than overweight and obese adults who drink sugar-sweetened beverages” (Diet-Beverage consumption and caloric intake among US adults 2014). S0 0verall overweight or obese adults who drink diet beverages and are trying to lose weight must also decrease solid-food calorie intake in order to lose weight. Some of the main ingredients used in diet sodas contain artificial sweeteners that include high fructose corn syrup and Aspartame. The article done by The American Journal of clinical nutrition suggested that the digestion of high fructose corn syrup (HFCS) is different from the digestion of glucose. Glucose stimulates insulin secretion and enhances leptin production which act as a “key afferent signals in the regulation of food intake and body weight.” According to George A. Bray Fructose on the other hand lacks the ability to regulate food intake and body weight which means that “dietary fructose may contribute to increase energy intake and weight gain … the increase in consumption of HFCS has a temporal relation to the epidemic of obesity, and the overconsumption of HFCS in calorically sweetened beverages may play a role in the epidemic of obesity.” When large amounts of fructose are consumed in the body it “relatively unregulated the source of carbon precursors for hepatic lipogenesis”, which is the transformation of nonfat food materials into body fat (Consumption of high-fructose corn syrup in beverages may play a role in the epidemic of obesity 2004). The article had a study done which showed that HFCS were introduced just before 1970 and increased by forty percent by 2000. Thus proving, after many more studies and research, that the upturn use of HFCS was simultaneous with the increase in obesity rates in the United States.
In the article “Diet beverages and the risk of obesity, diabetes and cardiovascular disease: a review of the evidence” researchers indicate that in the United States the purchases of diet sodas is much lower than the purchases of sugar sweetened-beverages (SSBs). However, the research found that “artificially sweetened beverages (ASB) became popular over the last few decades, largely due to successful marketing campaigns implying that consumption of such beverages would assist with weight control or weight loss.” Researchers in this article examined the past evidence on the relationship between the rise of diet beverages and the risk of obesity, diabetes, and cardiovascular disease. The data collected found that it is almost impossible to know whether there is a relationship between ASB intake and the risk for obesity and related chronic diseases. Researches are lacking in accuracy and consistency because of the “respect measurement error in the exposure and outcomes, observational cohort studies are not likely to contribute to clear and consistent findings on this topic” (Diet beverages and the risk of obesity, diabetes and cardiovascular disease: a review of the evidence 2013). Although diet sodas and other zero calorie beverages may seem like good alternatives to the original product it is important to keep in mind that there may be more risks than benefits. After reading all these articles, I have found that substituting diet sodas for regular sodas will not produce the results that we may have in mind. Individuals who are looking to lose weight while consuming diet based beverages ought to make certain that they are not replacing the zero calories from the diet drinks with calories from snacks or food. When making diet sodas sugars are replaced with artificial sweeteners. Artificial sweeteners contain high fructose corn syrup which lacks the ability to regulate food consumption and body weight. High fructose corn syrup works as a tool for transformation of nonfat food materials into body fat, resulting in gaining higher body mass index (BMI). Diet sodas can be beneficiary to the society when individuals are watching their intake calories on solid foods.

Phenylalanine

...Phenylalanine is a critical and required amino acid for the normal biological productions of proteins. The body requires a certain amount of phenylalanine because it does not produce it naturally. The human body obtains Phenylalanine thru proper diet. Thru the biological process of protein formation the body converts phenylalanine into tyrosine, which is essential to form required chemicals and proteins that the body needs to functions normally. Deficiency of phenylalanine causes numerous healthy problems such as altered state of mind, lack of energy, memory issues, confusion, and decreased alertness. High blood levels of phenylalanine can also be bad. High levels of phenylalanine can lower intelligence, causes anxiety and depression, and the inability to focus or pay attention. This is why phenylalanine is such an important molecule. Too much of it can cause problems and a deficiency also causes health problems, therefore it is important to be educated about it. The IUPAC name for phenylalanine is (2S)-2-Amino-3-Phenylpropanoic Acid. There are also common names of phenyalanine, L-Phenyalanine and D-Phenylalanine. Phenylalanine is a nonpolar hydrophobic molecule, which is why it is buried inside proteins. Phenylalanine is an aromatic compound with a melting point of 283 degrees Celsius. It has a solubility of 26.9 grams per mole. The structural formula can be seen on the cover page and it’s molecular formula is C9H11NO2. Phenylalanine is found in protein. It is...

Dr.Whitaker and Food

...Harvey Wiley, Theodore Roosevelt, and the Federal Regulation of Food and Drugs By Anthony Gaughan Food and Drug Law Mr. Peter Barton Hutt Harvard Law School Winter 2004 Introduction In 1906 Congress passed two landmark pieces of legislation: the Pure Food and Drug Act and the Meat Inspection Act. The acts emerged from the reformist ethos of the Progressive Era, a time when the federal government took on a new and much more active role in the everyday lives of ordinary Americans. Of all the laws passed during the Progressive Era, no legislation proved more successful and more enduring than the 1906 food and drug legislation. The acts established the foundations of modern American food and drug law, and gave birth to the Food and Drug Administration. For the first time, the federal government assumed permanent and comprehensive responsibility for the health and safety of the American food and drug supply. Although the statutes have been revised many times since 1906, the essence of modern food and drug law remains consistent with the principles of federal responsibility for consumer safety that underlay the first statutes a century ago. The passage of the 1906 food and drug legislation stemmed from the actions of many people across the political landscape, ranging from Senator Albert Beveridge to socialist writer Upton Sinclair. But no indi- 1 viduals played a larger public role in the passage of the Meat Inspection Act and the Pure Food and Drug Act than Theodore...

...BeachBody.com’s straight forward guide to eating so you lose fat and improve your health forever – 100% GUARANTEED! Step-By-Step DIET GUIDE 6 STEPS LET’S BEGIN... The actual goal of most fitness and slimming programs is to increase the ratio of lean muscle to stored fat. That means trimming a lot of fat and toning/building muscle. It does not mean “losing weight.” We’ve heard ads that promise 10 pounds of “weight loss” in a weekend. And the only way that is possible is by losing water weight. Maybe you’ll lose a pound or two of fat by starving your body along the way. But the rest is water weight. And of course, as you re-hydrate, your weight will go right back up — but because you starved your body, your metabolism was reset! So the next time you eat food, your body will be ready to store any leftover calories as fat. And soon you’ve got more fat stored than when you started. Not good. to transform your body. 1 CONTROL your portions. Don’t eat until you are full, eat until you’re not hungry. 1 CONTROL your portions. In restaurant terms, generally, eat half what the chef serves you. An adequate portion of a meal is 3 ounces of protein (like chicken, tuna or lean ground beef) which is about the size of your palm. Don’t eat until you are full. Eat until you’re not hungry. Same goes for salad dressing; On a large salad, limit it to just enough for taste. You will be surprised how much less dressing you need to get the same flavor. Control Your Calorie Intake and Portion Size...

Answers to Conceptual Sciences

...Answers to Conceptual Integrated Science End-of-Chapter Questions Chapter 1: About Science Answers to Chapter 1 Review Questions 1 The era of modern science in the 16th century was launched when Galileo Galilei revived the Copernican view of the heliocentric universe, using experiments to study nature’s behavior. 2 In Conceptual Integrated Science, we believe that focusing on math too early is a poor substitute forconcepts. 3 We mean that it must be capable of being proved wrong. 4 Nonscientific hypotheses may be perfectly reasonable; they are nonscientific only because they are not falsifiable—there is no test for possible wrongness. 5 Galileo showed the falseness of Aristotle’s claim with a single experiment—dropping heavy and lightobjects from the Leaning Tower of Pisa. 6 A scientific fact is something that competent observers can observe and agree to be true; a hypothesis is an explanation or answer that is capable of being proved wrong; a law is a hypothesis that has been tested over and over and not contradicted; a theory is a synthesis of facts and well-tested hypotheses. 7 In everyday speech, a theory is the same as a hypothesis—a statement that hasn’t been tested. 8 Theories grow stronger and more precise as they evolve to include new information. 9 The term supernatural literally means “above nature.” Science works within nature, not above it. 10 They rely on subjective personal experience and do not lead to testable hypotheses.

Sugar

...How Sugar is Made - the History It is thought that cane sugar was first used by man in Polynesia from where it spread to India. In 510 BC the Emperor Darius of what was then Persia invaded India where he found "the reed which gives honey without bees". The secret of cane sugar, as with many other of man's discoveries, was kept a closely guarded secret whilst the finished product was exported for a rich profit. It was the major expansion of the Arab peoples in the seventh century AD that led to a breaking of the secret. When they invaded Persia in 642 AD they found sugar cane being grown and learnt how sugar was made. As their expansion continued they established sugar production in other lands that they conquered including North Africa and Spain. Sugar was only discovered by western Europeans as a result of the Crusades in the 11th Century AD. Crusaders returning home talked of this "new spice" and how pleasant it was. The first sugar was recorded in England in 1099. The subsequent centuries saw a major expansion of western European trade with the East, including the importation of sugar. It is recorded, for instance, that sugar was available in London at "two shillings a pound" in 1319 AD. This equates to about US$100 per kilo at today's prices so it was very much a luxury. In the 15th century AD, European sugar was refined in Venice, confirmation that even then when quantities were small, it was difficult to transport sugar as a food grade product....

Pants on Fire

...MEG CABOT Pants on Fire One “Oh my God, what’s she doing here?” my best friend, Sidney van der Hoff, was asking, as I came up to the corner booth to hand out menus. Sidney wasn’t talking about me. She was glaring at someone at another table. But I couldn’t be bothered to look and see who Sidney was talking about, since my boyfriend, Seth, was sitting next to her, smiling up at me…that smile that’s been making girls’ insides melt since about the fifth grade, when we all started noticing Seth’s even white teeth and highly kissable lips. It still freaks me out that out of all the girls in school, I’m the one he picked to kiss with those lips. “Hey, babe,” Seth said to me, blinking his long, sexy eyelashes—the ones that I overheard my mom telling Sidney’s mom over the phone are totally wasted on a guy. He snaked an arm around my waist and gave me a squeeze. “Hi,” I said, a little breathlessly. Not just because of the squeeze, but because I had a twelve-top (Mrs. Hogarth’s ninety-seventh birthday party) that was running me ragged, refilling their iced tea glasses and such, so I was panting a little anyway. “How was the movie?” “Lame,” Sidney answered for everyone. “You didn’t miss anything. Lindsay should stick with red; blond does nothing for her. Seriously, though. What’s Morgan Castle doing here?” Sidney used the menu I’d just given her to point at a table over in Shaniqua’s section. “I mean, she’s got some nerve.” I started to say...
