Carbohydrates
There are four different types of carbohydrates which are saccharides, starch, NSP’s and sugar substitute. Saccharides
Saccharides are soluble in water.
A simple sugar is monosaccharide which is easily absorbed by the body.
The type of saccharides sugars are fructose, glucose and lactose.
No more than 11% of an adult’s sugar should be sugar Food sources that saccharides can be found white bread energy drink biscuits chocolate sweets Starch
Starches are polysaccharides; this means many molecules of glucose are linked together.
The properties of starch are very different from that of glucose
Starches are not water soluble and they require being chemically altered to allow them to be digested.
Food sources that starch can be found
Pasta
Rice
Potatoes
Couscous
Good cereals
NSP’s
It is also known as dietary fibre.
These include substances such as fibre.
Some of these are insoluble and cannot be broken down by digestion.
They pass through the body chemically unchanged

turning the food you eat into energy

In this report the two population groups that I have chosen are the childhood and adult hood. In this report I will be discussing the similarities and differences that these two population group have. The similarities between children and adults they both need a good balanced diet for their body to function properly. For these two different population groups it is very important that their body receives the right amount of nutrition that their body needs to function properly.
The first population group that I am going to discuss is childhood. Childhood is one of the most crucial stages for growth and development in every way. It is very important for children to have a well balanced diet to aid their development. It is important that their body receives enough nutrients and energy that their body requires to function properly. Child hood is the stage where children are very active and their body will require more energy than any other stage in their life. This is because the children are usually more active as well as developing.
Functions of nutrients in childhood.
In childhood Carbohydrates provide the energy that is needed for the children 's metabolism. In childhood carbohydrate supports growth and development, helps keep the children’s brain and nervous system working and also carbohydrate maintains overall health in children. Children need carbohydrates to make energy that is required by their growth, development and activities. This is the age group that children need the most energy in their life time, this is because they are at their peak level of their growth and development. Also the children are constantly active at this time especially because they begin to join school and their play becomes more active so they need more energy than any other population groups. Essential fatty acids are critical to developing and maintaining the brain. Fats are useful in building cell membrane and hormone production. It is important that the children’s diet contain essential fatty acids because it can help with the development as well as provide energy for the body to fuel. Kids’ health suggests that children need fat in their diet for their brain and nervous system to develop properly. (Kids health; 24/11/14) also fat helps the body to absorb some vitamins and minerals. Also fat is a type of fuel for the children’s body like the carbohydrates which provides them with energy. A child needs protein for growth and repair of the cells. Protein helps to replace cells that have died out in the body. Also protein helps to build muscle organs and glands. Protein is important for the correct development of the child’s body. It also helps with absorbing vitamins and minerals that the child receives from their diet. Without protein the children won’t be able to heal any wounds or replace any dead cells in the body.
Vitamins and minerals are also important for the growth and developments of children. This is because for children vitamins can be stored in the body and used again when their body requires them as energy. All the different vitamins and minerals have a vital role to play in the children’s growth and development. For example different vitamins and minerals have different roles to play like vitamin A helps with eyesight.
In adulthood you need carbohydrates for energy in your everyday life. This is because adults use energy to work and to do everyday activities. Adults need to control their intake of carbohydrates according to their lifestyle and job. This is because adults stopped developing at this stage of their life so they only need the intake of energy for their everyday life. If they intake too much of carbohydrate then the body will store it as fat to use when the body runs low of energy.
Adults need a guided amount of fat in their diet depending on their lifestyle because too much fat can cause obesity, heart disease. This will mean that their health will suffer because of their life style choice. Although fat can be bad, adults body will need some amount of fat to function properly. This is because some fats are useful for the body because they are used to absorb the vitamins and minerals that the adults are receiving from their diet. Adults need to watch their intake because of the higher level of cholesterol.
Adults need the protein for growth and repair of their body. Th.is is because adults need to replace the dead cells with new cells and also repair any damage done to their body quickly. For example if there is a cut the protein will help heal the cut by forming new cells where the skin was torn. They also need vitamins and minerals for their body to function properly. They need the vitamins and minerals for all the different functions of the body. For example adults need a lot of vitamin A because without vitamin A their eyesight will be poor.
The similarities between children and adults are that they both require carbohydrates, fat, protein, vitamins and minerals because these are vital building blocks of life. Everybody needs different amounts of these nutrients according to their needs. The one similarity that I have notices is that both of these population groups needs carbohydrates in their diet for their body to have some energy to function properly. Another thing that I noticed is that both of these population groups need only small amount of fat. This is due to the fact that their body only needs the small amount of fat to function in these two population groups. The reason for this is that fat is stored in the body if the body receives too much; the body stores the fat for future use. Both of these population groups require vitamins and minerals equally but in different amounts according to their body’s needs. Vitamins are used for growth and repair, so it’s not possible for any of the population groups to go without vitamins as they are require for functioning of the body properly.
The difference between the two population groups that I have discussed is that they both need all the nutrients at different quantities. Also the nutrient requirements will vary from person to person depending on their needs. From the two population groups children require the most carbohydrates and fat because they are very active and still developing whereas the adults will only need a much smaller amount of these nutrients because of their lifestyle and also because they have finished developing.

    A person’s diet is the food they regularly consume, for example a high fibre diet contains a lot of fruit and vegetables. A nutrient is anything that nourishes a human or animal for example iron is a nutrient if someone is a vegetarian they don’t get a lot of iron so they have to take iron supplement tablets. A meal is a fairly large portion of food that is served and eaten for example a roast dinner which contains vegetables, meat and potatoes. A snack is a small amount of food eaten in between meals for example a sandwich. Malnutrition is caused by people having to many or too little nutrients, this can cause poor wound healing, fatigue and organ failure. Over nutrition is where you take in too many nutrients, this affects energy balance and leads to obesity. It also affects health, for example high intakes of salt are linked to high blood pressure. Under nutrition means not getting enough nutrients and can lead to starvation, mirasmus and kwashikor. All of these conditions can lead to low self esteem, depression, anxiety and in many cases anger problems.…

    Complex carbohydrates are also called starches. Starches include grain products, such as bread, crackers, pasta, and rice. As with simple sugars, one should watch where they receive their complex carbohydrates, because not all of them are good for the body. Refined grains, such as white flour and rice, have been processed, which removes the extra nutrients and fibers. However, unrefined grains still contain the extra vitamins and minerals. Unrefined grains are also rich in fiber, which helps one digestive system digest food better. The fiber that is in the unrefined grains helps your body feel full, so that one is less likely to eat too much, and gain extra weight. An example of this is that a bowl of oatmeal in the morning will help fill you up, rather than a sugary candy bar that has the same amount of calories that the oatmeal has.…

    On a daily basis we decide what we are going to put into our bodies with the knowledge that what we choose to eat affects the body in different ways. Carbohydrates are one of the crucial macronutrients that perform an essential role in fueling the human body. They provide the body with energy and in order for the body to use carbohydrates for energy food must undergo digestion, absorption, and glycolysis. It is recommended that 55 to 60 percent of our caloric intake come from carbohydrates. It is important to keep in mind that there are different types of Carbohydrates. There are good and there are also bad carbohydrates and it is up to us to choose which ones to digest as part of a healthy diet. Eating a healthy diet would ideally include Carbohydrates but it is…
