In this assignment I am going to identify the characteristics of nutrients and explain what their benefits are to the human body, and furthermore I will also be assessing the similarities and the differences in both the nutritional and energy requirements for two groups of individuals.
Our bodies in order to function correctly need six main nutrients which are; Carbohydrates, Protein, Fat, Minerals, Vitamins, Water. All six of these keep the body’s natural defences up and allow for new healthy cells to be created replacing old cells.
These are the body’s main source of energy because when a carbohydrate enters the human body we break them down in our stomach, which then ...view middle of the document...
These are attached to one and other and when seen under a microscope they are usually connected in long chains.
Proteins have many different functions within the body but one of the functions is that they work as Antibody’s, which are attracted to foreign particles such as the bacteria and viruses we commonly pick up to help protect the body from illness.
Although too much fat is unhealthy for our bodies we do need so much for our bodies to again function correctly, and even though our bodies need fats we cannot make fat in our system and so it has to be consumed as food.
Triglycerides are the fats cholesterol and the essential fatty acids that it contains, although the common scientific term for these fats that our systems cannot make are that:
• They Store Energy
• They Insulate Us
• They Protect Our Vital Organs
Fats also have another function in the body by acting as messengers so that proteins within the body can function effectively; the fats also create chemical reactions to occur within our system which helps:
• Control Growth
• Immune Functions
Lastly fats also help to store other nutrients within our systems as well, such as the fat soluble vitamins like vitamins, A, D, E, and K. These vitamins are all stored within the liver in fatty tissues.
Minerals often have multiple functions within the human body such as calcium is good to help the development of strong teeth and bones, but at the same time assists in the development of healthy nerve function, good muscle contractions, and lastly the enzyme and blood clotting.
Some minerals have vital roles to the body however such as Potassium which helps to regulate the fluids within your body, but also helps to lower the blood pressure.
Potassium can be broken down from many foods such as; Vegetables, Fish, Milk etc.
Another mineral that’s vital for the body to function is Zinc which has multiple functions such as creating new cells and enzymes to replace old or damaged ones. It’s also good for repairing any damaged tissues within the body such as muscles and organs.
Once again Zinc can be absorbed from many foods like; Meats, Milk, and Bread.
Vitamins also have multiple functions within the body such as minerals, they are commonly heard of as helping the body to maintain strong bones and heal wounds that the body may have.
Although not all vitamins do the same and each one has a different function to keep the body functioning healthy, such as vitamin C for example which helps the body to absorb iron and also helps the body to keep cells and tissues healthy from and bacteria and viruses that we may catch.
Vitamins also help the body to create energy the same as minerals although vitamins help to repair cell damage so that new cells made are healthy and able to carry out their function.
Trying to keep track of what vitamins do for our bodies can be confusing because we may not...
