1. There are receptors also in the stomach that send signals to your brain. Sugar is unfortunately empty in nutrition which leaves you still hungry.
C. Dopamine is released in the brain in large amounts
1. The chemical released in the brain for pleasure. But the more often you release dopamine from a particular source, the more you grow a tolerance to it.
2. Due to these releases and the tolerance build up, there are people who are susceptible to becoming addicted to these sugary food.
D. When sugar is broken down in the body it becomes two simple sugars, Glucose and Fructose.
a. Glucose is in every cell and is produced by our own bodies
b. Fructose is not produced by use and our body has no real need for it
i. Fructose can only be metabolized by the liver ii. Overeating sugar overloads the liver which makes the liver turn the fructose into fat. Doing this in repetition leads to a fatty liver and other serious health effects. This is similar to drinking too much alcohol.

Sugar

.... At 5:30 am the slaves would be sent to the fields with their breakfast. A register would be called and if a slave was absent he would be beaten. Their breakfast at 8:00, consisted of Boiled Yam, Eddoes and Okra which were all seasoned with Salt and Pepper. Work on the sugar Plantation now started, this is where the majority of the Slaves worked. It continued till 12:00 and was a very tiring time. The sugar cane can range from a height of 4 feet to 12 feet or more. Knives were used to cut the stems of the cane and then were at the end of the day, carried to a sugar mill. Here a different set of workers would squeeze the sugar cane to get the precious juice that is used to create sugar. This was a very important job so the smallest mistakes would be punished severely. From 12:00 to 2:00 pm the slaves were allowed to leave their work and have dinner. These often consisted of meaty dishes, as they contain lots of protein which is needed to use muscle. .From 2:00 to 6:00 the slaves had to continue with their work. This was often the time when problems would occur. Many weak slaves would faint in the evenings from extreme heat, and overworking. If this was to happen they would be whipped. At 6:00 the slaves were allowed to return to their huts. After eating bread and butter, or some other light dinner at their hut, they would either be sent to bed, or in the summer forced to work in the boiling house. 3. When the African Slaves were enslaved, they sang slave songs. Some...

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....

Sugar Love

...Bottom of the Drink They had to go. The Coke machine, the snack machine, the deep fryer. Hoisted and dragged through the halls and out to the curb, they sat with other trash beneath gray, forlorn skies behind Kirkpatrick Elementary, one of a handful of primary schools in Clarksdale, Mississippi. That was seven years ago, when administrators first recognized the magnitude of the problem. Clarksdale, a storied delta town that gave us the golden age of the Delta blues, its cotton fields and flatlands rolling to the river, its Victorian mansions still beautiful, is at the center of a colossal American health crisis. High rates of obesity, diabetes, high blood pressure, heart disease: the legacy, some experts say, of sugar, a crop that brought the ancestors of most Clarksdale residents to this hemisphere in chains. “We knew we had to do something,” Kirkpatrick principal SuzAnne Walton told me. Walton, Clarksdale born and bred, was leading me through the school, discussing ways the faculty is trying to help students—baked instead of fried, fruit instead of candy—most of whom have two meals a day in the lunchroom. She was wearing scrubs—standard Monday dress for teachers, to reinforce the school’s commitment to health and wellness. The student body is 91 percent African American, 7 percent white, “and three Latinos”—the remaining 2 percent. “These kids eat what they’re given, and too often it’s the sweetest, cheapest foods: cakes, creams, candy. It had to change. It was about the...

Sugar Reflection

...Malcolm Warner Human Nutrition 3534 Reflection on Sugar 2-17-2014 After watching the assigned videos about sugar I was surprised at the effects that sugar has on the human body and the amount of sugar in many of our processed foods. Many Americans do not pay attention to the serving sizes on the nutrition labels which leads to consuming a massive amount of sugar per day. The facts provided in the documentaries can help people have a better understanding of their sugar consumption and maintain good health. One of the facts that can really help is four grams of sugar equals in teaspoon, men should have about nine teaspoons of sugar per day while women should have around six. As our sugar consumption has grows, so does our bodies. Our risk of obesity, diabetes, and heart disease increases because of the excess amount of sugar in our diets. In one of the documentaries, it specified that a lot of the research about sugar and the evidence provided comes from animal trials which made me question some of the evidence. In another documentary it was explained that sugar is made up of two molecules, glucose and fructose; glucose helps fuel our muscles and our brain while the fructose (which is also in our fruits) is separated and goes to the liver. Too much fructose can liver fat and can start a downstream of metabolic diseases. I don’t necessarily agree with calling sugar “poisonous” and “toxic”. Too much of anything can be bad for you. Drinking an excess of water can be hazardous...

THE sugar - cane plant was the main crop produced on the numerous plantations throughout the Caribbean  through the 18th, 19th and 20th centuries, as almost every island was covered with sugar plantations and mills for refining the cane for its sweet properties. Layout of the 18th century plantation West Indian sugar estates varied in size from a few hundred to several thousand acres, according to soil, climatic and physical geographical conditions. An average estate measured about five hundred acres and was laid out according to an almost regular pattern. THE estate land consisted of a number of clearly defined parts. In the hey-day of plantation agriculture, the greater part of the estate was devoted to sugar-cane cultivation. This portion was usually the best land since the...

Composition of Sugars

...Lab: 3—Chemical Composition of Cells: Sugars Purpose of this lab: To learn about sugars and the test used to identify them. Introduction The organic macromolecules known as sugars are a type of carbohydrate. Carbohydrates are composed of monosaccharides, which are single, sugar unit monomers. Two sugar units linked together are known as a disaccharide. In this lab, we conducted tests on various substances with Bendict’s solution to determine which sample contained sugars. Benedict’s solution is a turquoise blue color and reacts with sugars after being heated in a boiling water bath, resulting in a color change. The color change varies with the concentration of sugar present, with strong positives indicating a high sugar concentration and weaker positives correlating with lesser concentrations of sugar. The color changes are as follows: orange-red (very high), orange (high), yellow-orange (moderate), yellow (low), green (very low), no change in color (no sugar present). Materials and Methods: --6 test tubes marked at 1cm and 3cm from the bottom --Benedict’s reagent --substances to be tested: water (control), glucose solution, onion juice, potato juice, starch suspension, and an unknown substance --hot plate with a beaker filled with water for a boiling water bath Each substance to be tested was filled in a separate test tube to the 1cm mark, with the exception of onion and potato juice, to which 5 drops of each were added to separate...

Sugar Effects

...Subject Terms: *NONNUTRITIVE sweeteners *ASPARTAME *SUGAR substitutes *DEGENERATION (Pathology) *FOOD additives *CARCINOGENICITY RISK factors Author-Supplied Keywords: Artifi cial sweetener aspartame sugar substitute Abstract: Sugar is an inseparable part of the food we consume. But too much sugar is not ideal for our teeth and waistline. There have been some controversial suggestions that excessive sugar may play an important role in certain degenerative diseases. So artificial sweeteners or artificially sweetened products continue to attract consumers. A sugar substitute (artificial sweetener) is a food additive that duplicates the effect of sugar in taste, but usually has less food energy. Besides its benefits, animal studies have convincingly proven that artificial sweeteners cause weight gain, brain tumors, bladder cancer and many other health hazards. Some kind of health related side effects including carcinogenicity are also noted in humans. A large number of studies have been carried out on these substances with conclusions ranging from "safe under all conditions" to "unsafe at any dose". Scientists are divided in their views on the issue of artificial sweetener safety. In scientific as well as in lay publications, supporting studies are often widely referenced while the opposing results are de-emphasized or dismissed. So this review aims to explore the health controversy over perceived benefits of sugar substitutes. [ABSTRACT FROM AUTHOR] Copyright of Journal...

I have learned in past years attending leadership conferences about the Hippocampus: a part on the Brain that seems to be important is establishing new memories, from strong emotions. In order for a memory to move through the hippocampus and into our long term memory two things need to transpire. 1. Emotion or Passion 2. Purpose, we respond to our present situation from our past experiences or pain.

Sugar Cane

...Sugar Cane Today, sugar cane has many industrial uses and is one of the most widely used and cheapest domestic products Sugarcane is a tropical, perennial grass that forms lateral shoots at the base to produce multiple stems, typically three to four meters high and about five centimeters in diameter. Sugar cane probably originated in the island of New Guinea. Its cultivation spread along human migration routes to South-East Asia, India and to Fiji and Hawaii in 500-1100 AD. Sugarcane is the world's largest crop. In 2010, FAO estimates it was cultivated on about 23.8 million hectares, in more than 90 countries, with a worldwide harvest of 1.69 billion tonnes. Brazil was the largest producer of sugar cane in the world. The next three major producers, in decreasing amounts of production, is India, China, and Thailand Sugar is an addictive food, not only in humans but also in dogs and pigs and other animals with simple stomachs. Excessive sugar induces at least one type of cancer and late- onset diabetes. It also 'crowds out' other energy foods. Despite this, sugar is now part of most processed food and drink of every kind in advanced countries, especially the USA. Unites State's one of the biggest sugar cane companies is Unites States Sugar Cane Corporation.

American Sugar Counsel

...The American Sugar Council reported a study on the relationship between children's sugar consumption and hyperactivity. For the study, they recruited 30 volunteer families and asked them to keep a food dairy for 30 days. At the end of the 30 days, parents were asked to complete a questionnaire detailing their perceptions of their children's energy and activity levels, specifically after consuming sugary treats. By comparing the energy and activity levels of children who consumed large amounts of sugary foods with those who did not, the Council concluded that there is no link between sugar consumption and hyperactivity. (This is a fictional example.) 1.Do you believe the conclusions of this study? (Make sure to back up your conclusions with ideas from the reading, not just your personal experience or opinion.) I do not believe in the conclusions of this study. As stated on pg. 303 in the textbook, a “treatment” or “experimental” group may not be enough to get actual results because of the potential placebo effect. And there are many other factors that should be taken into consideration before they can draw up that type of conclusion. For example body composition and amounts of sleep could easily make the energy results change drastically. 2.What are the strengths and weaknesses of the study design? Weakness: To reinforce the second half of my belief in the conclusion, on pg. 300 it talks about representative sample. In this study there isn’t one! The placebo effect that...
