The Intake Of Synthetic Sugar

“The Toxic Truth About Sugar”, written by Lustig et al. varies in their usage of rhetorical strategies to try to have their readers better understand that sugar, as common as it is, can be very dangerous when a big amount is consumed in one day. The numbers in our world don’t lie: A shocking statistic is that there are currently thirty percent more people who are obese than there are healthy. This discussion arose from the staggering facts that obesity is becoming more of an epidemic than ever before. The United States has a choice to make: Take the steps necessary to slow obesity or do nothing at all, like it feels we are currently doing. This can be a good or bad rush, depending on how you assess the situation.

7. What is the normal physiological response to increased intake of sugars? To increased intake of caffeine?

This experiment was carried out as noted about in Procedure 1. The resting heart rate was established and used as a baseline value from which to compare all future deviations. While data could

Exercise increases heart rate by a process of sympathetic autonomic stimulation. Sympathetic (adrenergic) nerves increase the excitability of the sino-atrial node and reduce the P-R interval .As exercise continues, the physiological changes in the body are continuously monitored by a number of physiological systems and the balance of activity of the sympathetic system (speeding up) and the parasympathetic system (slowing down) is constantly adjusted. When exercise is over, the heart rate does not drop immediately as the body has to undergo a period of re adaption to return to the resting state.

The authors then share their analysis on the changes of heart rate and GSR at the many different points throughout their study.

The resting heart rate fluctuates over time because it is under control of the autonomic nervous system and the fluctuations are a result of the sympathetic and parasympathetic systems trying to balance each other out.

In order to complete this exercise, two different procedures were conducted; one measured the basal heart rate, and the other measured the drug-induced heart rate. A sample 's basal heart rate can be defined as the “resting” heart rate. This is when no drugs or altering substances are applied. In comparison, the drug-induced heart rate of a sample can be defined as the heart rate after the drug was administered to the surrounding environment. The four drugs tested on the Daphnia specimens were Acetylcholine, Caffeine,

Tachycardia: Tachycardia typically refers to a heart rate that exceeds the normal range for a resting heart rate. When the heart beats rapidly, the heart pumps less efficiently and provides less blood flow to the body and the heart. The rapid heartbeat increases the workload and oxygen demand of the heart. Problems will occur with the heart as tachycardia persists over time. The heart is maintaining less oxygen, which will lead to an MI due to death of the myocardial cells. Patient will start to have angina because of this. Tachycardia is noted in many diseases and disorder like: fever endocarditis, anemia, HTN, pericarditis, abnormal heart impulses, anxiety, older age, sleep apnea, COPD, electrolyte imbalances, and many more.

The American diet is based mostly in processed food which contains enormous amount of sugar. The excessive consumption of sugar can cause diseases such as obesity, heart diseases, alzheimer, liver diseases, diabetes and others. One of the problems with the consumption of sugar is that people get sick progressively without the knowledge that it is caused by sugar. In addition, sugar is an addictive food and life without it is almost impossible. As a result, processed foods are cheaper than healthy food. It is hard to avoid processed food when Americans do not have time to cook because of their life style. Americans need to know the way to change their diet and improve their lifestyles. Americans sometimes forget about the amount of sugar that a soda or flavored drink contains. These drinks are tasty, but it will not satisfy thirst. Sugar is equally dangerous and has the same health effects than smoke cigarettes. Consume sugar in excessive amounts per day have a significant effect in Americans ' daily life. Americans should be aware of the diseases caused by their eating habits, therefore; they should be more conscious of what they eat and change their diet.

In my experiment as the concentration of sugar increased the heart rate of the Daphnia decreased. The cause of this may have been to the possibility of having a defectuos daphnia. My prediction was that the more sugar concentration added the highest the Daphnia heart rate was going to be. It did affect my organism but not in a positive way if not in a negative way, by decreasing the heart rate of the organism.

When most people think about sugar, their first thoughts are not: heart disease, addiction, or slow and painful death; yet, unfortunately, these conditions are very real consequences of the unregulated and excessive consumption of sugar. In Nature’s article, “The Toxic Truth About Sugar” (2012), Robert Lustig, pediatric endocrinologist; Laura Schmidt, Professor of Health Policy at UCSF; and Claire Brindis, Professor of Pediatrics and Health Policy at UCSF, evaluate the world’s ever-increasing and toxic struggle with the substance sugar – also discussing counter measures to promote healthier diets amongst American’s and other societies. Lustig and his colleagues develop their argument using statistical evidence as they address the global impact of sugar, refuting minor oppositions, before dissecting each harmful aspect of the substance – even comparing it to substances more known for their toxicity. Eventually, presenting readers with possible routes of regulation, the authors firmly suggest government intervention in the production and sale of sugary foods. Although the argument is well executed, I remain unconvinced that government intervention is actually necessary.

Throughout the course of everyday life, variability of heart rate is present for each individual. As the college students on the campus of Truman State University go about their day-to-day lives, they too experience the phenomenon of heart rate variability. While resting and using little movement, many students spend a great number of hours each day studying - a period of time when the body requires a smaller cardiac output in relation to times of movement. However, during the course of an academic day, Truman students, like the majority of human beings, are faced with instances under which time is limited, and they must increase work output to get from one destination to another. Additionally, there are instances in which physical activity is required with variation of difficulty within a workload/resistance. Through this understanding, one can see that the heart rate changes throughout the course of each day, and is thus dependent on the intensity of each daily activity. Although every student on Truman State University’s campus has his/her own unique physiological makeup and personal physical fitness level - every individual is impacted by the variability of his or her own heart rate in response to activities of daily life.

The spike in blood glucose levels after ingestion of simple sugars is thought to be related to some of the heart and vascular diseases which have become more frequent in recent times. Simple sugars form a greater part of modern diets than formerly, perhaps leading to more cardiovascular disease. The degree of causation is still not clear, however.

The experiment began by taking the height and weight of all of the participants. Those taking part performed two trials on separate days. For the first trial, participants consumed water at leisure throughout the day, then at 3:00 pm, preceded to the gym to begin the experiment. Before exercising, the first participant placed the Suunto brand heart monitor under their shirt on their breastbone and fastening the display watch on their right wrist. The participant’s heart rate was recorded before beginning the exercise. The wattage of the Precor RBK 835 Recumbent exercise bike was then set to 80 watts and the participant rides the stationary bike at an intensity that maintains the wattage range between 80 and 90 watts. After five minutes of riding,

The subjects were chosen from the University of Colorado Denver physiology lab. All were students and age ranged from 18 to 35 years, without any health concerns. A quick screening of the health related questions: do you have a pacemaker, do you have exaggerated reactions to stimuli, and do you have any health problems, was conducted to test for the participants health concerns.
