According to Witney and Rolfes 2012, Vitamin C is a water-soluble vitamin that is necessary for normal growth and development. Water-soluble vitamins dissolve in water and leftover amounts of the vitamin leave the body through the urine. Hence the reasons why we need a continuous supply of this vitamin our diet. Vitamin C in humans must be ingested for survival. It is an electron donor, and this property accounts for all its known functions. As an electron donor, vitamin C is a potent water-soluble antioxidant in humans.
Vitamin C is a necessary vitamin for the body to carry out its functions properly. It is also known as ascorbic acid. It is a water-soluble nutrient that is found in some foods. It acts as an antioxidant in the body which helps to protect cells from the damage caused by free radicals, which are formed when our bodies convert the food we eat into energy. The body needs vitamin C to make collagen which is the protein required in wounds, healing. Moreover, vitamin C promotes the absorption of iron from fruits and vegetables and helps in promoting the immune system. Vitamin C is also important to protect our body from cardiovascular disease, prenatal health problems, eye disease, and skin wrinkling. We can obtain vitamin C from food and other sources.
When one hears the three words: vitamins, nutrients, and minerals, they think of one thing-being healthy and noticing what your intake is daily. Nutrition is all about vitamins and nutrients. Firstly, vitamins are an organic compound required by the body in small amounts of metabolism, to protect health, and for proper growth of children. Vitamins also assist in the formation of hormones, blood cells, nervous systems chemicals, and genetic material. There are 13 well-identified vitamins. Some examples of the 13 well-identified vitamins are: A, D, E, and K-fat contained foods, B, C-consumed immediately. A well known and commonly used in commercials for orange juice vitamin is vitamin C. Vitamin C or ascorbic acid is important in the synthesis and maintenance of connective tissues. The lack of vitamin C will result in a sickness called scurvy. Scurvy harms the gums, mucous membranes, and the skin. Another well-known vitamin and is also used to commercial to give more information about this beverage is the vitamin in milk. The vitamin in milk is vitamin D. If you do not drink milk and obtain this vitamin, your bones and teeth will become soft and weak. Lacking one or more of the 13 well-identified vitamins will cause sickness and weakness to your body. Secondly, nutrients are how the body assimilates certain compounds. Nutrients are classified in 5 major groups: proteins, carbohydrates, fats, vitamins, and minerals. One of the five nutrients is carbohydrate. The carbohydrate group principally consists of sugar, starch, dextrin, cellulose, and glycogen. In more basic terms, carbohydrates are sugars needed by human and other living organisms. Some types of foods that contain carbohydrates would be candies, ice cream, fruit juice, soda, chocolate bars etc. Lastly, vitamins are connected to minerals. Minerals are also a very important part of a healthy person. There are 11 major groups of minerals. They are: calcium, chromium, copper, iodine, iron, magnesium, manganese, phosphorous, potassium, selenium, and zinc. All these terms look very familiar if one has taken chemistry. These are the elements of our world. One of the more common minerals that most people have heard of is calcium. Calcium also helps with the structure and strength of teeth and bones. Vitamins and minerals work together to help humans maintain a healthy body. For example, vitamin D works with calcium to help for and maintain the strength of teeth and bones.

A child two to eight years old need the same four unsettles to be healthy. The only difference is that they need a different amount of each that an adult. They must eat the recommended intake in each food group corresponding with their age and sex stated in the Canada’s food guide. They must also get daily excurses, with lots of sleep. The National sleep foundation recommends that children one to five years old should get 11 to 14 hours of sleep each night (National sleep foundation, n.d.) They must also get the right nutritious vitamins to help them grow. A good way to achieve this is with a child baste motley vitamin. I will be inspecting the intake of food a child in daycare consumes each day to see if them meet the recommendations set by The Canada food guide. Studying their strengths and weaknesses and how thy can be improved.
The 13 well-identified vitamins are classified according to their ability to be absorbed in fat or water. The fat-soluble vitamins-A, D, E, and K-are generally consumed along with fat-containing foods, and because they can be stored in the body's fat, they do not have to be consumed every day. The water-soluble vitamins-the eight B vitamins and vitamin C-cannot be stored and must be consumed frequently, preferably every day (with the exception of some B vitamins, as noted below).
“If we could give every individual the right amount of nourishment and exercise not too little not too much, we would have food the safest way of health” (Barasi.E.M, 2003). This essay is going to discuss on the important of six essential nutrients in human body. According to PosnerB.M (1998), he define essential nutrients as a nutrients that the body cannot synthesize on its own-or not to an adequate amount and must be provided by the died. Oxford dictionary (2009), also define essential nutrients as are those nutrients that are required by the body and cannot be synthesise in the adequate amount to meet requirement, so must be provided by the diet. Essential nutrients are those found to be essential to human life and optimal function, Williams.M. H (2006).There are six main type of nutrients used to maintain body health. They are carbohydrates, protein, fat, vitamins, minerals and water. They must be in balance for the body to function properly.
The human body requires small amounts of nutrients in microgram or milligram quantities in our diet because it cannot synthesize the necessary amounts on its own. These nutrients are considered micronutrients. Micronutrients are a combination of water, vitamins, and minerals. Vitamins are organic compounds that do not provide energy, but are essential to the body in helping “aid in metabolism, as well as the growth, development and maintenance of body tissues” (Byrd-Bredbenner, Moe and Beshgetoor 402). Vitamins are broken down into two groups, water-soluble and fat-soluble. The water-soluble vitamins are the B-vitamins, and vitamin C. The fat-soluble vitamins are A, D, E, and K. Minerals are needed in even smaller amounts, however these inorganic substances are necessary for “cell metabolism, nerve impulse transmission and growth and development” (Byrd-Bredbenner, Moe and Beshgetoor 485). Minerals can be categorized into major or trace minerals. The major minerals include Sodium, Potassium, Chloride, Calcium, Phosphorus, Magnesium, and Sulfur. Trace minerals are Iron, Zinc, Copper, Manganese, Iodine, Selenium, Chromium, Fluoride, Molybdenum and Ultratrace minerals.
Vitamins are essential aids in many body processes, converting food the energy, building and maintaining cells, and other functions.

Nutrition is the process of nurturing or being nourished; the total of all the processes that a plant or animal uses to take in and process food substances to maintain a healthy life. A healthy nutrition life style requires a balanced diet of food selected from the five basic food groups, fruits, vegetables, naturally calcium rich dairy products or calcium enriched products, whole grains, and protein (lean meat fish, peas and beans). Other nutritional factors should also be considered. Most fruits and vegetables are better if they are consumed raw because heating destroys some of the healthy nutrients.
