What is the effect of storing and preparing food on it’s vitamin C level?
Introduction
Vitamin C is essentially for both humans and animals to remain being healthy. In fact, when people get colds, they consume large amounts of vitamin C to try to fight off the cold. Vitamin C can be found in many fruits and veggies, buts it’s most common in oranges. A deficiency in vitamin C can cause a condition known as scurvy. Scurvy plagued sailors through the 19th century from the time of Columbus. Scurvy is characterized by blood coming out of a ruptured blood vessel, or hemorrhages, throughout the body, most especially noticeable on the gums and around the mouth and other areas of the skin that has abundant blood vessels. The only way to stop scurvy was a diet consisting of citrus fruits.
Vitamin C is viewed as an important water soluble “antioxidant.” Since antioxidants are chemical compounds that readily donate electrons, they can block potentially harmful free radical reactions. In order to stay healthy, the Food and Drug Administration recommends a daily dose of 60 mg of vitamin C.
Vitamin C is also known as ascorbic acid, which can be written C6H8O6. The structure of ascorbic acid is shown in the image to the left. Since vitamin C is easily oxidized, the majority of its functions rely on this property. Ascorbic plays a key role in the body’s production of collagen, which is the main structural protein in the connective tissues of animals. Since a human’s body does not produce vitamin C naturally, it must be taken in from one’s diet. Vitamin C can be found in fruits, vegetables, and organ meats (liver or kidney). The amount of vitamin C in plants varies greatly depending on such factors as variety, weather, and m...

One piece of evidence I have comes from a document called, "Understanding the Value of Multivitamin." In this document the author, Komaroff, A.L, says, "... For example, a deficiency of Vitamin C causes scurvy." In this line Komaroff is stating how Vitamin C can cause scurvy, which is a disease that makes us lose our teeth and so much more. In the same document they then stated, "... Such severe vitamin Deficiency are rarely seen in the developed countries. However, eating foods rich in vitamins still brings benefits… " So even if you wouldn't take multivitamins to get rid of vitamin deficiency diseases you can still take it to rid of other major killers. These major

A study carried out by Telang (2013)(14) showed that 10 % of vitamin C applied topically decrease UVB induced erythema by 52% and sunburn cell formation by 40-60%. Vitamin C has a role to reduce the melanin formation by inhibition of tyrosinase enzyme that decrease dark spots. It has photo aging protection due to promoting collagen synthesis, as it is essential cofactor for enzymes required for its biosynthesis as a result, decrease wrinkle appearance (15).
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.
Food science has led to find cures for diseases such as scurvy. Scurvy is a disease caused by a deficiency of vitamin C, characterized by swollen bleeding gums and the opening of previously healed wounds, which particularly affected poorly nourished sailors until the end of the 18th century. This disease was very common among sailors because in the 18th century they didn’t have refrigerators, so their diets lacked perishable foods while sailing the sea. Today, if you come across this problem you can just eat a vitamin C tablet. This is just one of the many examples food science has promoted a balanced diet by the study of nutrients in our food.
A well-balanced diet contains all the necessary vitamins, and most individuals who follow such a diet can correct any previous vitamin deficiencies. However, persons who are on special diets, who are suffering from intestinal disorders that prevent normal absorption of nutrients, or who are pregnant or lactating may need particular vitamin supplements to bolster their metabolism. Beyond such real needs, vitamin supplements are also often popularly believed to offer "cures" for many diseases, from colds to cancer; but in fact the body quickly eliminates most of these preparations without absorbing them. In addition, the fat-soluble vitamins can block the effect of other vitamins and even cause severe poisoning when taken in excess.
Vitamin E in all its forms, functions predominantly as an antioxidant by protecting cells from free radicals in the body. Vitamin E works as an antioxidant by donating a hydrogen atom from a hydroxyl group to a free radical within the body. Vitamin E also plays a role in immune system function and protects cell membranes and regulation of gene expression. Vitamin E has been studied to uncover other medical usages, including prevention or treatment of many health conditions [1].
Aim: To investigate the vitamin C content of fruit juice. Introduction In this experiment I will be finding out which fruit juice contains the most vitamin C. I will be using a method similar to titration, but I will be using a syringe instead of a burette. Vitamin C Vitamin C, also known as ascorbic acid, is needed for growth and maintenance of healthy tissues, especially skin, blood vessels, bones, gums, and teeth.
Calcium is essential to normal functioning in a healthy individual; this only leaves the question of where to get it. There are many sources available to meet daily requirements, two of which are dairy products and supplemental vitamins. Both of these options have qualities that make them appealing, so choosing might be difficult or even come to a middle ground. Some of the considerations to be made are: what calcium is, the types of calcium in each source, how much should be ingested daily, the body’s ability to absorb and tolerate calcium from the chosen source, and the interactions that might occur with other medicines and required daily nutrients. In both cases a decent nutritional diet still needs to be incorporated. It may seem like a simple choice between a couple of pills a day or 3-4 glasses of milk, but there is quite a bit more
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.
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
My average intake is 66 mg. it is lower than the required Vitamin C intake. Deficiency in Vitamin C can develop scurvy, if vitamin C is missing on our diet. Oranges, lemon and other citrus fruits, bell pepper, kiwi broccoli, berries, tomatoes and papayas are rich in Vitamin C . Lack of Vitamin D on diet can develop rickets to small children. The required intake for this vitamins is 15microgram and my report is zero. Vitamin D can be achieved from exposure of skin to ultra violet rays of the sun. Vitamin E is responsible for transmission of nerve impulses, body weakness and eye problem that can cause blindness. My nutrient intake for Vitamin 10 mg AT and the require intake is 15 mg AT, which is 5 mg lower than the require amount. Food related to Vitamin E are green leafy vegies such as spinach, kale are rich in Vitamin E, in addition, broccoli, hazel nuts, squash and pumpkin are also rich in Vitamin E. My vitamin K intake is 3 microgram, way too low compared to the requirement which is 90 microgram. Vitamin K deficiency can cause hemorrhagic disease of new born. Food that gives Vitamin K are green leafy vegetables such as kale and spinach, canola oils, olive oils, and
If we continue to eat unhealthy it can cause some huge problems in the future. When eating unhealthy you have less vitamins in your system, which can cause some severe diseases. One is the lack in vitamin C can cause a disease called Scurvy. Early Symptoms of Scurvy are weakness, feeling tired, and sore muscles. Later it causes decrease in red blood cells, gum disease, and bleeding from the skin.
The nutrients we get from eating fruits and vegetables are also very important in our daily diet. When we eat anything we get nutrients from it, but the question is are we eating too much? Too much of a good thing can be bad! The different vitamins have many different purposes, vitamin A keeps the eyes and skin healthy and helps protect against infections. Vitamin C helps heal cuts and wounds and keeps your teeth and gums healthy.
