The County Fair.
Jennifer Rinder English Comp 1113 May Intersession 2003 Martha Hodges May 23, 2003 The County Fair Food can be an evocative portal to memory. Mary had not had time to eat breakfast before beginning her monotonous trek across the city to her monotonous job. By mid-morning she was starving. Images of the snack vending machine began to block out her computer screen and obscure the shimmering letters on her keyboard. The cravings for sugar and salt made it difficult for her to concentrate. The protesting emanations from her stomach would soon exceed the clattering noise of her typing. She had to wait until the clock on the wall displayed the exact moment that her break would begin. It would be a short break and Mary would have to rush to reach the nearest vending machine. Now it was time. Mary jumped up, grabbed her purse and was off to the underground tunnel that led to the nearest snack haven. She darted into the dank passageway and was drawn to the bright light at the other end. She started running, oblivious to the curious looks of her fellow travelers. Success she was there. Nirvana, the vending machine! By this time her hunger had made her aggressive and intolerant. She growled at the indecisive people ahead of her, and patiently tapping her foot and sighing heavily to signal her distress. Finally it was her turn. Mary
Proteins in Nutrition.
Proteins in Nutrition Proteins are very large molecules made of amino acids, of which there are twenty. Eight of these amino acids are "essential," meaning that they cannot be synthesized in the body even though they are necessary for life. Essential amino acids must be consumed from sources outside the body. Early in the twentieth century, studies of rats revealed that this rodent grows better using animal sources of protein. Knowing nothing of humans, which are harder to study because they live so much longer, grow to adulthood so much slower, and metabolize food so much slower, nutritional scientists applied what they had learned about rats to humans. The conclusion was that animal sources of protein were superior to plant sources for human nutrition because of the higher concentration of protein. In the early 1950s, definitive studies were conducted on human beings, and the eight essential amino acids were identified. Both animal and plant sources of amino acids provide an abundance of the essential amino acids. As it turns out, the amino acid needs of human beings can be met better by some plant sources, such as soy, because plant protein comes without the heavy load of fat present in meat, milk and eggs. Milk is said to be a good source of protein. Perhaps so, but the problems associated with pasteurized milk and milk products make it a less than
Kashrut essay (food laws)
AO2 Kashrut is a key part of the dietary habits of Jews and they feel that it is very important to observe this. The only food that Jews can eat is kosher food, which means fitting or correct food that is in the state of being kosher is the only food, which Jews can eat. The foods that Jews cannot eat are called triefah. Jews food do not have to be blessed by the Rabbi although he may be consulted if the is conflict as to whether a certain food is kosher or not. Jews may eat meat eat food from animals but they must have certain characteristics "These are the animals which you may eat... anything which has a completely split hoof and chews cud, this you may eat..." (Leviticus 11:2-3) This means that the only animals or livestock that Jews can eat have to chew the cud this is where they chew the grass, it forms balls in their stomachs know as ruminants and then regurgitate it then chew it again. Jews can only eat these animals. Also the animals must have a split hoof such as that of the cow. Only animals, which possess both of these characteristics, are kosher .All other mammals are treifah. For a bird to be Kosher it must be written in the Torah in Leviticus 11:13-19 there is no other way of recognising kosher birds other than this method. Although there are a number of birds written in the torah that Jews can eat in reality Jews tend to only eat duck turkey and
The Importance of Vitamins and Minerals In the Human Body.
Laura Canzano IB Biology SL Research Paper2 6/12/2002 The Importance of Vitamins and Minerals In the Human Body. The human body is a very complex machine that, just like any machine need the proper tools and instructions for it to work well. One of the factors that play a big role in the well being and health of the human body is its need for vitamins and minerals. Vitamins are " any of a group of organic substances found in food and essential in small quantities to normal metabolism"1 In other words, the term vitamin is derived from the words vital and amine, because vitamins are required for life and were originally thought to be amines. Although not all vitamins are amines, they are organic compounds required by humans in small amounts from the diet. An organic compound is considered a vitamin if a lack of that compound in the diet results in evident symptoms of deficiency. Humans require at least 13 different vitamins in their diet. On the other hand minerals can be defined as " a neutral inorganic substance,"2 they are elements that originate in the Earth and cannot be made by living systems. Most of the minerals in our diets come directly from plants or indirectly from animal sources. In the body, minerals play a number of vital roles. Several mineral elements are necessary to maintain the structural integrity of bones and teeth, while others are required for
Fatty and sugary foods
Fatty and sugary foods This group includes spreading fats (such as butter), cooking oils, sugar, biscuits, cakes, crisps, sweets, chocolate, cream and ice-cream and sugary drinks. These foods shouldn't be eaten too often; when they are, they should only be consumed in small amounts. They're loaded in calories, fat and sugar, but don't contain many vitamins and minerals. In addition, sugary foods and drinks (including fruit juice) can significantly contribute to dental decay. Try to limit the amount of sugar and sweets eaten. If they are eaten, offer them at the end of a meal rather than in between. Some sugar-free or diet drinks can also cause decay because of their acidity. Milk or water are the best drinks between meals. Nutritional considerations Although growth is slower than in infancy or early childhood, school-aged children still have high nutritional needs, but fairly small appetites. Therefore, it's crucial that all meals and snacks are nutrient-dense. A recent Government report provided detailed information on the nutritional intakes of young people aged four to 18 years. The findings of this survey offer the first real insight into the health of young people in more than 17 years. While nutrient intakes were surprisingly robust, there are a number of areas of concern identified by the findings. With falling activity levels and increasing levels of obesity
The environmental issues associated with pest control
The environmental issues associated with pest control Pests are living organism which is considered to have a detrimental effect on humans. Pesticides are normally used to combat these pest. Pesticide is a chemical compound often delivered in a spray, which kill pest or inhibits their growth. For example insecticide is a pesticide which kills flies. DDT has also been used to kill mosquitoes and lice; however this substance is now banned in Britain. Pest can be controlled by chemical pesticides. This is the use of toxic chemicals to kill pests. They can also be controlled by biological control; biological control is deliberately increasing the number of predators or parasites of the insect pest. Here are some examples of biological control (see fig 1.1). Fig 1.1 (from New Understanding Biology Book) Target (pesticide) Harmful effects of pest Control agent Method of action Scale insect (icerya) Kills citrus fruit trees Ladybird (rodolia) Ladybird uses scale insect as a food source Codling moth (crytophlebia) Ruins orange crop African wasp (trichogamatoidea) Wasp parasitizes moth eggs Dichlorodiphenyltrichloroethane (DDT) was used in the Second World War. This played a vital role in controlling fleas, lice and other disease carriers. "It was subsequently used to kill mosquitoes, and helped control malaria"2. DDT is now banned in Britain because it accumulates
Chocolate Bakewell Tart
Chocolate Bakewell Tart Pastry case * 50 g margarine * 25 g white fat * 125 g plain flour Filling * 75 g jam * 50 g self-raising flour * 30 ml Bournville cocoa * 50 g margarine * 50 g caster sugar * 1 egg * 25 g ground almonds * 2.5 ml almond essence * finely grated rind of a lemon 8-cm flan ring, on a baking tray Make up the pastry by rubbing the fats into the flour, until the mixture resembles breadcrumbs. Add just enough cold water to bind the mixture together. Knead lightly and roll out the pastry on a floured board. Line the flan ring, being careful not to stretch the pastry or it will shrink. Keep the scraps for the trellis. Spread the jam in the base. Sieve the flour and cocoa. Cream the margarine and sugar together and slowly beat in the egg. Fold in the sieved flour and cocoa and stir in the ground almonds, essence and the grated lemon rind. Spread the mixture evenly in the pastry case. Roll out the scraps of pastry, cut strips and arrange them in a trellis across the top. Stick the ends on to the flan with a little water. Bake in a fairly hot oven (200ºC, 400ºF, Gas Mark 6) for 15 minutes then reduce the heat to moderate (180ºC, 350ºF, Gas Mark 4) for a further 15 minutes or until cooked. Serve hot or
How can Malnutrition be caused by social, economic, cultural and environmental conditions.
Amrit Purba How can Malnutrition be caused by social, economic, cultural and environmental conditions. Malnutrition is a condition where the diet is not balanced resulting with a deficiency disease. It happens worldwide but can be more common to developing countries, as economic, social, cultural and environmental conditions all have an influence A balanced diet involves sufficient amount of carbohydrates, lipids, fibre, protein, vitamins, and minerals and water. Lack of these nutrients or overload can increase the risk of having a deficiency disease. High amounts of lipids (fats) cause obesity, because of the high-energy content. This causes strain on joints; leading to foot-problems, pressure on the spine and more work for the heart. Lipids also increase the risk of Coronary Heart Disease (CHD), by blocking the coronary arteries. Fat and cholesterol accumulates in artery walls causing Arteriosclerosis- where the wall of an artery bulges and blocks blood flow. Cholesterol occurs in saturated lipids (no double-bonds) such as animal fat and butter. Hence the reason to eat less fat and substitute for other means like vegetable oil and unsaturated lipids. Even though one only needs a small dose of vitamins and minerals, it is an essential dietary requirement otherwise resulting in a deficiency disease. Lack of Vitamin C causes skin problems like Scurvy. Without
Measuring the Amount of Energy in Food.
GCSE Biology Measuring the Amount of Energy in Food Prepared by: Scott Bayfield Nutritional Experiment to Aid Polar Expedition Contents Planning Page 3 Expected results Page 3 Equipment list Page 4 Health and safety issues Page 4 Variables Page 4 Method Page 4 Results Page 5 Analysis Page 7 Test Evaluation Page 8 Planning The objective of this experiment is to evaluate the energy that can be gained from certain food types, (namely peanuts and spaghetti) and calculate which of these foods is most suited as a core dietary item during a polar expedition. In addition to the nutritional benefits, consideration must also be made in respect of the equipment required for cooking the food as well as the foods cooking time and weight. To measure the chemical energy produced by each food type, the food is burned and the heat produced by the flame is used to increase the temperature of water held in a test tube directly above the fire. The increase in temperature is then converted into a measurement of energy (kilojoules). Expected result Preliminary predictions can be made based on what we already know about the nutritional values of the two food types. They are as follows: (Nutritional information) Peanut Spaghetti Fat 53g Fat 2g Carbohydrates 7g Carbohydrates 69g Protein 28g Protein 3g Fibre 6g Fibre
School Project
Mikhail School Menu The Hayes Manor School After several lessons, planning and discussing our coursework we had the opportunity to learn of different things. Then finally we chose to create a leaflet containing the school menu (school health eating program) with eating tables and patterns. This is meant to explain the school menu and diet patterns on a day-to-day basis. I had to translate the leaflet into different languages o it could attract more people to read it not only in English but also in other languages which they understand. Our school has a high number of people from other backgrounds, therefore there are 64 languages spoken all around. The decision to help the school on a project was influenced by everyone. As there were a lot of suggestions we agreed to vote on which ones people found quite helpful. I thought if people knew which kind of food was healthy then they would want to know more about it. Our co-coordinator/teacher suggested we pair up with someone we felt comfortable working with as would make the project fun. We translated all our projects o different languages because our school is multicultural. We couldn't get any volunteers to translate the project and this led to us holding a search for a site we could use to help us with the translation. This school menu is meant to increase nutrition amongst the students through implementing healthy
