Iron helps blood to carry oxygen, a lack of this causes anaemia. Calcium helps build healthy strong bones and teeth. Vitamins:- there are many diseases caused by the lack of vitamins even thou only a small amount is needed by the body. Vitamin A helps to maintain healthy skin, growth and good vision. Vitamin B helps the release of energy from other food and is good for the nervous system.
Vitamin losses can occur through chemical reactions which lead to inactive products. With regards to food chemistry, the main concern is to maximize vitamin retention by minimizing aqueous extraction (leaching) and chemical changes such as oxidation and reaction with other food constituents for a small vitamin deficiency can already cause diseases in humans (Fennema, 1996). Vitamins are mainly classified into two based on solubility: the fat soluble vitamins and the water soluble vitamins. Fat soluble vitamins are composed of Vitamins A, D, E and K while
It is very important that a person stays hydrated because water makes up more than half of your body weight, and not staying hydrated can result in your body shutting down and possible death. Your body uses water in many ways, all the cells in your body need water to function. All of your body’s tissues need water, and all of your body’s organs need water to function correctly. Some of the ways that your body uses water are ; water is used to regulate your body’s temperature, you sweet to lower your temperature when your body is overheating. Water is also used to carry vitamins and minerals to our body’s cells.
Vitamins help keep the human body healthy as well as allowing it to function properly. Vitamins are considered an essential nutrient that the body needs because the body cannot produce them. Vitamins enter the body orally to be digested by the body for use. There are many types of vitamins that do certain things for the body. They also have certain solubility that helps classify them into two categories; fat-soluble and water-soluble.
Good nutrition is the balance of an adequate diet combined with with regular physical activity and is essential for good health. Inadequate or poor nutrition can lead to decreased health and lowered immunity increasing the risk of disease. Insufficient nutrition can also result in impaired mental and physical development. Once food is ingested by the body it can be broken down into macro or micro nutrients. Macro nutrients are the structural, energy providing parts of food they are required in small amounts by the body.
This assignment will evaluate the importance of homeostasis in maintaining a healthy functioning of the body. If homeostasis did not work properly in the body then there are many problems that could arise. Diabetes is one of those problems: Diabetes Diabetes is “a permanent change in your internal chemistry that results having too much glucose in your blood” because the body cannot use it properly. (Rudy, 1999, Page 10) Glucose comes from digesting carbohydrates and is also produced by the liver, carbohydrate comes from many different kinds of foods and drink, such as Wholegrain cereals such as Weetabix and Shredded Wheat, Brown rice, Pasta and Potatoes. “Diabetes can be tackled in different ways- by insulin and diet” (Rudy, 1999, page 19) Diet, when someone had diabetes it is best for their health to cut right down on the unhealthy foods, and stick to the health foods, this is due to the effectiveness of the medication you are on.
There are two different types of carbohydrate, simple carbohydrates (or sugars) and complex carbohydrates (starches and fibre). Proteins are a vital nutrient which us used by the body for growth and repair, it is very important for infants and children also individuals who are ill or injured. one characteristic of proteins is that they are made up of amino acids. They are complex molecules that can promote good health. Lipids are insoluble within water, they have high energy content and can be metabolized to release calories, but they have many other uses as well.
She believes the milk industry is one of capitalism’s greatest deceptions (De Vivo). Surprisingly, studies show that milk is not good for you and has little nutritional value. Milk can cause constipation, stomach aches, food rejection, reflux, and allergies. The milk industry’s biggest statement is that it contains a good source of calcium. According to Marcela and an article from Cindy Cleary and Jo DelAmor, calcium in milk cannot be absorbed in our bodies because there is not a sufficient amount of magnesium.
But before I begin, I should explain the importance and function of vitamins and minerals in your body. Vitamins and minerals are crucial when it comes to the body carrying out all it's functions. They also keep you looking and feeling healthy. A deficiency of vitamins and minerals in your body will cause you to be disease prone. Different kinds of micronutrients help with different tasks the body needs to complete in order to survive.
There are many underlying health conditions that result in specific nutrient needs and influence what people can or cannot eat. For example people who suffer from conditions such as diabetes mellitus, coeliac disease, irritable bowel syndrome, lactose intolerance and food allergies will probably have to be very careful of what they eat due to consequences such as weight gain, serious food allergic reactions as well as very uncomfortable symptoms like abdominal pain, vomiting, diarrhoea etc. So it is important that they have to exclude certain foods from their diet, which could influence their dietary intake as well as their nutrient intake. There are also other who are unable to absorb certain nutrients into their bodies and this can cause a deficiency of those nutrients, so they have to take supplements. In conditions such as diabetes mellitus in which the hormone insulin is either not being produced in the pancreas at all, or it is being produced in insufficient amounts or it could also be that the body is not utilising the insulin produced properly.
