Salt case study
Large amounts of salt can be hidden in canned, processed and convenience foods. Salt can be found in many foods that are served in fast food restaurants.
There are many high salt foods and they Include: pizza bacon ham regular and processed cheese pancake and waffle mixes bottle salad dressings instant pudding or cake There are also many low salt foods such as: mayonnaise dried fruits instant mash potato ready to eat cereals corn and flour tortillas noodles Ice cream yogurt There are hundreds and thousands of different types of meals in the world.
Here are some examples of low salt meals. Greek lamb with orzo Creamy corrugate lasagna Parmesan spring chicken Sizzled lamb steaks with warm beetroot salad Having salt in food is not necessarily causing a problem however if we have too much salt it could lead to high blood pressure. High blood pressure has no symptoms but If you have It, you are more likely to develop heart disease or have a stroke. Here are some examples of high salt meals.
Macaroni and cheese with smoked ham Beef and cheese burritos Grilled red snapper America’s cut eternally Salt and Health Raised blood pressure (hypertension) is the major factor which causes strokes, heart allure and heart attacks, the leading causes of death and disability in the ASK.
Also, there is an increase in evidence of high salt intake and stomach cancer, obesity, kidney stones, kidney disease and osteoporosis. Stomach Cancer A high salt diet increases the risk of stomach cancer. A quarter of the 7000 new cases each year can be attributed to salt. The bacterium Helicopter pylori (H. Wooly) is the major risk factor for stomach cancer as it can lead to inflammation of the stomach which can lead to stomach ulcers and stomach cancer. H.
Pylori in the stomach will to necessarily cause damage but salt can damage the lining of the stomach, making it more vulnerable to the effects of H. Pylori. Salt may also incase the growth and action of the bacterium making it more likely to cause damage. Obesity A quarter of British adults are obese and two thirds are either obese or overweight. Obesity is linked with numerous health conditions such as high blood pressure, diabetes, CHAD and sleep pane.
Salt does not cause weight gain itself but it does cause you to become thirsty and this leads you to drink more fluids. If the fluids are sugary drinks they can cause weight gain because they contain a lot of energy. This is a major concern for children and teenagers because a third of the fluids they drink are sugary soft drinks. Kidney Stones and Kidney Disease Kidney stones are a common problem, caused by a build up of calcium in the kidneys. Both a high salt intake and high blood pressure can cause too much calcium to be excreted by the kidneys into the urine leading to build up of calcium and therefore kidney stones.
They can be extremely painful and in some cases, lead to kidney cancer.
He kidneys control fluid balance and blood pressure by controlling the amount of fluid lost from the blood into urine. A high salt diet can disrupt the function of the kidneys to cause high blood pressure. This in turn puts a strain on the kidneys leading to kidney disease. Osteoporosis Osteoporosis is a condition which causes thinning of bones making them brittle and prone to breaking. In the UK an estimated 3 million people are suffering from osteoporosis. Most calcium in the body is stored in bones.
A high salt diet can cause calcium to be lost from bones excreted in the urine making bones weak and daily Rosen. High blood pressure caused by a high salt diet can speed up the loss of calcium Trot Done, worsening ten problem. Older people are most at rolls AT osteoporosis because bones naturally become thinner as we get older. Sources of Salt Salt can be extracted from seawater by evaporation or by growing salt crystals. If you extract salt from either of these ways then you can produce salt for food and cosmetics, however if fossil fuels are used to heat the salt solution then it has disadvantages of creating air pollution.
Shaft Mining Shaft mining is where miners go underground to remove solid rock salt. This involves digging shafts and tunnels in the rock to get at the layers of rock salt. Large machines travel through vast cave-like passageways performing various operations. Salt is mined by the room and pillar method. This salt is removed chess board pattern to leave permanent solid salt pillars to support the mine roof.
In shaft mining you get rock salt. Rock salt is mainly used for roads when it gets icy to keep the grip when vehicles drive along the roads. Solutions Mining Solution mining where water is pumped underground dissolving the solid salt.
Wells are drilled into the salt deposit. Tunnels are drilled to connect these wells. Then water is pumped down one well, the salt below is dissolved, and the salt solution is forced to the surface through the other well.
This has to be carefully controlled to avoid subsidence. The solution is then piped into large tanks for storage before the water is evaporated. In solution mining you get salt water, which once evaporated, the solid salt remains. Salt can be used on foods like fish and chips but also can be used to preserve meat. Disadvantages and Advantages There are both disadvantages and advantages to both types of mining salt.
In Shaft mining, the disadvantages are that you have to send an actual person down to mine. Also, in shaft mining you use explosives to break down the walls which could cause disruption to living organisms. The advantages are that using the room and pillar method will keep the ground from subsiding and creating a pit in the ground. In solution mining, the biggest disadvantage is that it can cause subsidence. Because the water is being put down into the ground to dissolve the salt, the rock will begin to get softer and softer which increases the chances on subsidence.
The advantages are hat it is much less disruptive to the environment and living organisms in the ground. I think majority of my information is accurate. For the grade E research, I had gotten my information from INS choices and SCUFFS health which I believe are both reliable and up to date resources. For my grade D research, the recipes of my low and high salt meals were from BBC good foods which isn’t the most reliable resource as they are recipes from people who have made the dish but have also edited the dish. Also some recipes could be outdated for years or weeks etc so that doesn’t make it the most reliable resource.
In the grade C research I used a website called actions which I wasn’t sure about being accurate or not.
Because I didn’t know if it was reliable I checked with other sites and they were pretty similar answers. For the grade B/A/A* questions I used my chemistry book from school which is reliable because it is a school material which is used in many schools across the country. I think the information given in those books are of accuracy. Overall I think majority of my research is reliable but there are some parts of my research where I think that the information could be incorrect.
