Vitamins There are lots of different vitamins that the body needs to maintain healthy, however they are only needed in small amounts. The body cannot make these vitamins so therefore they must be in a person’s daily diet. Vitamins are categorized into two groups these are fat-soluble vitamins and water soluble vitamins. Vitamin A, D, E and K are all fat-soluble vitamins, this means that they can dissolve in the presence of fat. • Vitamin A has different important jobs. It helps the immune system work properly to fight against infections; it keeps the skin healthy and also helps vision in dim light. Cheese, eggs and oily fish are all good sources of vitamin A along with liver which is particularly rich with this vitamin. Adult women should …show more content…
The main source of vitamin D is sunlight; however foods like oily fish and eggs are both good sources of this vitamin. Most people will get more than enough of what they need of vitamin D a day; however there are certain population groups that will be a risk of not getting enough. • Vitamin E has different jobs. It helps maintain healthy eyes and skin, keeps the immune system healthy and strong and protects cell membranes. Adult men need at least 4mg per day, and women need at least 3mg a day. Plant oils like soya and corn are the richest foods for vitamin E but nuts and seeds and cereal products are good sources. • Vitamin K is important in someone’s diet as it is needed for blood clotting and helps wounds heal properly. Green vegetables like broccoli and spinach are good sources of vitamin K along with vegetable oils and cereal grains. The amount of vitamin K adults need depends on their weight. It is around 0.001mg for each kilogram of their body weight daily. So for someone who weight 58kg they would need 0.0058mg per day. Any excess vitamin K that is not used is stored in the liver where it can be used later on. Vitamin B and C are water-soluble vitamins which mean that they can be dissolved in the presence of …show more content…
Vitamin B1 is called thiamin which keeps the nervous system healthy and working correctly and works with other forms of B vitamins to break down foods and turn them into energy to be released. B1 can be found in vegetables, fresh and dried fruit, eggs and may other foods. Women need 0.8mg a day whereas men need just a little more which is 1mg a day. Vitamin B2 is called riboflavin. This helps out bodies release energy from the foods we eat but also makes sure that the skin, eyes and nervous system are kept healthy. B2 cannot be stored by the body so it is important that it is in a person’s diet and that they get it daily. Women should be getting be getting 1.3mg of riboflavin and men should be getting 1.1mg per day. Milk and milk products are good sources of this vitamin. Vitamin B6 helps form haemoglobin, which transports oxygen in the blood but also lets the body store the energy it gains from protein foods. B6 is also known as pyridoxine and can be found in a wide variety of foods this includes meat, fish, eggs and potatoes. Daily the recommendations say that women should be getting 1.2mg and men should be getting
Vitamin B12 is commonly obtained in the diet through consumption of meat, nuts, eggs, milk, shellfish, and green leafy vegetables (j). B12 has a large complex structure based around a corrin ring, which resembles porphyrin with a cobalt ion at the center (l). For this reason compounds with vitamin B12 activity are called cobalamin (k). Cyanocobalamin is the form typically found in fortified foods, which is converted in the body to the active forms methylcobalamin and 5-deoxyadenosylcobalamin (k).
Vitamin A, in its various forms, is an essential component of mammalian health. In addition to its well-documented role in vision, Vitamin A contributes to several other important biological functions including nuclear transcription, skin cell differentiation, growth, and immunity. As animals are not capable of synthesis, vitamin A and its metabolites (collectively know as the retinoids) must be obtained through the diet (Goodman 1984). Two major forms of vitamin A are found in food: retinol and carotenoids. All of these fat-soluble vitamins contain two distinct structural features that contribute to all of their activity. The first is a β-ionone ring to which the second critical motif, an isoprenoid chain, is attached.
The best sources of Vitamin D are foods and sunlight. Foods containing vitamin D include some fatty fish, fish liver oils, milk, cereal, orange juice, mushrooms and eggs [5]. In elderly, dietary supplements might be required to meet the daily need for vitamin D.
B12 is one of the 8 vitamins in the B family. It is in the make-up of every cell in your body. That is the important
Vitamin B12 or cobalamin is a water-soluble vitamin which is required by the body for a healthy brain, nervous system and red blood cells. This vitamin benefits your heart, mood, skin, hair, digestion and energy levels.
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.
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).
Vitamin B12 deficiency, or Cobalamin deficiency, occurs frequently among elderly people. Vitamin B12 is a nutrient that helps keep the body's nerve and blood cells healthy and helps make DNA, the genetic material, in all cells. Vitamin B12 also helps prevent a type of anemia called megaloblastic anemia that makes people tired and weak. Often times, the symptoms of this deficiency are undetectable because the signs are subtle. This creates several issues including identifying those at risk for deficiency and providing those individuals with the correct treatment. Throughout the paper I will address issues such as the causes and evaluations, treatments and procedures, and dietary impacts of vitamin B12 deficiencies using several studies related to vitamin B12 deficiency within the elderly. The purpose of this paper is to determine what the effect of lack of vitamin B12 has on the elderly and what, if any, can be a preventative for such deficiency.
Vitamin A and B1 through B6, which are found in most red meats, can cause harmful effects in the body. Vitamin A helps the development of healthy skin, bones, and eyes. If too much vitamin A is ingested, there is an increased risk of liver cancer and high cholesterol. Vitamins B1 through B6 helps the body produce energy and maintain heart health. However, an over abundance of these vitamins can cause high numbers of red blood cells and anemia. Vitamin B12 also helps with energy; however, when too much is ingested in the body an individual can develop a rare eye disease that causes blindness and severe amounts of blood clots throughout the body.

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.
Individuals who consume B vitamins don’t have to worry about overdosing because the vitamins are complex and water-soluble. This means there can be no build up in the body and is not likely to cause harm.
Vitamin D is a necessary component for calcium absorption to prevent boss loss. Nutritionally our body can create vitamin D by sun exposure however many factors can prevent our bodies to create vitamin D such as using sunblock or not getting enough sun exposer from daily routine. Vitamin D can be found in many foods that we such as milk including almond milk, eggs yolks, saltwater fish, and liver. Other vitamins that can help prevent bone loss are vitamin A and C. Vitamin C is an antioxidant which helps reduce oxidative stress which can have a negative effect on the cells in the body. This helps protect against inflammation which takes away calcium from the bones. Vitamin C can be found in many foods such as papaya, bell peppers, broccoli, Brussel sprouts, strawberries, pineapples, oranges and kiwifruit and fruit juices have supplement vitamins. Vitamin A is important for bone growth, vision, cell division and cell differentiation. There are two different forms of vitamin A are retinol and beta-carotene. Retinol can be found in meat, poultry, fish and dairy products while beta-carotene can be found in fruits, vegetables and
Vitamins are essential aids in many body processes, converting food the energy, building and maintaining cells, and other functions.
Vitamin C also known as ascorbic acid is needed for growth and maintenance of healthy tissues, especially skin, blood vessels, bones, gums, teeth. Vitamin C aids in resistance against infection and healing of wounds. It also helps the body absorb iron from food. Vitamin C can be found in green vegetables, potatoes, tomatoes and citrus fruits such as oranges and lemon. A lack of vitamin C can cause scurvy, iron deficiency and poor wound healing. A healthy diet should include a high amount of vitamin C because the human body cannot produce its own vitamin C.
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.
