Measuring Calories and Structure and Role of Macronutrients

My guess was incorrect for this look into the manufacturers calorie count was easily melloweder than the results of this experiment. Originally I thought that the manufacturers would agree a land calorie count in order to attract more than customers into have their products. Major companies would have proper facilities to be able to correctly streak the amount of calories in their products and there argon several things that could have given a more accurate reading in the experiment.I believe that this is the reason why the results from the experiment were so different to that of the manufacturers. It is Coperni bunghole to know exactly how many calories argon in the food and drinks we consume, this is beca workout our bodies exactly need a certain amount which we arse work discover with our BMR. BMR stands for Basal Metabolic Rate and to calculate this it takes into account the persons age, weight, top and average level of exercise.If someone who has a BMR of 2200 c alories and they are overwhelming 2500 calories severally day then that person will gradually sack up weight unless they increase their level of exercise, using this same type of thought process it would work the other way around, if the same person consumed 2000 calories each day then they would gradually lose weight. Considering the experiment actually showed that the manufacturers have stated lower amount of calories I think that the primary(prenominal) reason for this would be down to the experiment itself.If I could do this experiment again I would try to find a way to trap more of the h take in plant and send it towards the can, in this experiment the foil was just below the can which could allow a lot of rouse to be anomic to the environs which could make the results show the calories were lower than they really are. A nonher factor that could refer the results is that the tin can itself could take some of the heat away from the water, the experiment requires the wa ter to get heat to gather a reading however if the can must be heated before it can snuff it the water then heat energy will be lost in the process.One aspect of the experiment that I would definitely transfer if I did it again would be to test more foods and to test each one multiple metres rather than just once each, this can ensure a more accurate reading. Explain how cells and tissues make use of macronutrients and review the scientific evidence that supports the idea that an idiosyncratic with a high BMI may have an increased risk of develop cardiovascular disease. To keep back the human dust fiting correctly it needs nourishment, through eat and drinking the dead organic structure can get this.The most important nutrients the proboscis requires are called macronutrients they are called this because they are the big (macro) nutrients. There are leash macronutrients that are vital for the personate to survive and these are carbohydrates, fats and proteins. Carbohydr ates can be obtained through eat bread, cereals, honey or other sugars. These carbohydrates are the bodies main source of energy, once they are in the body they can be broken down in dickens ways, the simple sugars can be utilize straight away within the cells were as the more composite sugars need to be broken down by the enzymes in the intestine to make them into the simpler sugars.Once these sugars are in the cells they can be used for internal respiration to help the cells and tissues to function. If not all the energy from the carbohydrates is require then the body can also store it as fat. Fats are used for two main purposes, the first being insulation. When the environment is similarly cold for the body to handle fats can help to insulate the heat and keep our bodies warm. The second use of fats is food storage, when the body is not acquire liberal energy from foods it can break down these food stores to bring extra infallible energy.Fats can be obtained from foods such as cover or olive/sunflower oils. Proteins are the last macronutrient, these can be used for energy however this is not their main function. The main function of the proteins is the building and repair of tissues. Our muscles are made of an estimated 20% protein, when tissues such as muscles get damaged proteins are used to repair them so the body can function once more.Information provided by the BMJ (British Medical Journal) states that explore has shown youngsterren who have a high BMI between 9 and 12 historic period of age are more wantly to have high tear pressure, cholesterol and parenthood insulin levels (all risk factors for developing heart disease) by the time they reach adolescence. This shows that there is a link between BMI and the causes of cardiovascular disease. An individuals BMI can be calculated by using their cover and weight so it can tell you if you are over, under or the sinewy weight.So this research is basically saying that if a child is ove rweight and continues to be overweight, the chances are they could develop symptoms that commonly lead to cardiovascular problems. Being overweight can be caused by the body storing in like manner much fat, which in turn can be caused by eating too many fats and/or carbohydrates and not doing enough physical exercise. If a person has a high BMI it means that their body is getting more nourishment than it needs or is not using up enough of the carbohydrates leading to fat stores. Cardiovascular disease can be caused by a variety of different symptoms such as the ones mentioned in the report.An typeface of how these could be linked to having a high BMI could be high caudex pressure, if there are fats or cholesterol blocking a sidetrack of the cardiovascular system, the heart will have to work harder to pump the blood around the body and by doing this it is causing unnecessary work for the heart, and this is what leads to more life threatening problems. What is the role of vitamins and minerals in the human diet? pass water one example of each of the above that affect the same body tissue/organ if that are deficient. As well as the macronutrients the body also needs micronutrients (minerals) and vitamins.Examples of minerals would be calcium, iron, etc. These are important like the macronutrients however they are just needed in smaller doses good-looking them the name micro (small). Examples of vitamins would be vitamin C which is show in citrous fruit fruits and vitamin K which can be found in leafy super acid foods such as broccoli or spinach. Much like minerals, these are important just like the macronutrients but these vitamins are just needed in very small doses. Examples of how these can affect the human body would be calcium and vitamin D.Calcium can be mainly found in dairy products as well as leafy third estate vegetables. Calcium is what builds and maintains our grind away. Without calcium in our bodies bone density would decrease and would be more likely to suffer from breaks. As well as consuming enough calcium the body also relies on a healthy level of vitamin D, this is mostly produced in the skin through the use of basal violet rays from the sun. Vitamin D promotes calcium absorption within the body. This means that bones rely on a healthy balance between both(prenominal) calcium and vitamin D.If the body is deficient in either one of these two nutrients the whole skeletal system could be at risk of developing problems such as ricketts or osteoporosis. Ricketts is when the bones a softened repayable to the lack of calcium present in them, causing them to be abandoned to fractures or deformity. Osteoporosis is when the bones sour less dense causing them to weaken, become brittle and break. The main problem with osteoporosis is that once the bones have broken, they are difficult to heal again as there is simply not enough calcium to maintain them again.
