A Guide to the C Vitamin




The c vitamin has got to be the most widely known vitamin these days. It is not surprising because the body needs c vitamin for over 300 functions. In fact, the c vitamin has been proved to help protect against heart disease, cancer and other serious illnesses. Without the c vitamin the body would not be able to heal itself either. This is because the c vitamin is vital for the formation of collagen. Whenever a person has a cut or an injury it is the collagen that helps repair the damage and without sufficient c vitamin this would be almost impossible. Collagen has a multitude of functions in the body, including keeping the organs in place, and it would not be able to do this without sufficient c vitamin.





The c vitamin is also an antioxidant for the body and helps other vitamins and minerals to be absorbed better. Folic acid and iron, for example, need the c vitamin to maximise their usefulness. The more c vitamin that the body has, the better its defence against colds and other common ailments and the c vitamin may not prevent a person catching a virus but it does help speed up the recovery process.





There is c vitamin in almost every fruit and vegetable but some have far higher c vitamin content than others. Cranberries and melons have high c vitamin content. In fact, tropical fruits have the highest c vitamin amounts of all fruit. Hot peppers are amongst the richest sources of the c vitamin when it comes to vegetables. The hotter the pepper, the higher its c vitamin content is. Unfortunately, the c vitamin is water soluble so many vegetables lose their effectiveness as a c vitamin provider if they are boiled for a long time. Steaming or quick stir frying vegetables ensures that more of their c vitamin content is retained. The recommended daily amount of the c vitamin is easily obtained from eating five portions of fruit and vegetables a day if they are consumed raw or cooked quickly.





C vitamin supplements are extremely useful to ensure that people obtain sufficient c vitamin. However, with a balanced diet the amount of c vitamin the body receives is likely to be sufficient. However, if a person begins feeling tired or lethargic then a c vitamin supplement will help overcome this. There is no danger of having too much c vitamin as the body simply excretes the excess.

A Guide to the D Vitamin




The D vitamin is the only vitamin that is not obtained from foods that are consumed. Instead, the D vitamin is actually obtained by sunlight on the skin. There has been a lot of media coverage about the dangers of getting too much sun but it is essential that the skin is exposed to sunlight to obtain the recommended daily allowance of the D vitamin. In reality, the amount of time that a person has to spend in the sun to receive a sufficient dose of the D vitamin is extremely small and just a few minutes a day will be sufficient and not have any adverse effects from the amount of ultra-violet light received.





The most important function of the D vitamin is to help control how much calcium is absorbed from food. The majority of the calcium is used to build strong teeth and bones but it is also needed to send messages along the nerves and to help muscles, such as the heart muscles, to contract. It is the D vitamin that ensures that there is always sufficient calcium in the blood to perform these tasks. Other functions that require the D vitamin relate to the immune system and it is believed that it is also a contributing factor in reducing the risk of contracting cancer and, in particular, colon cancer.





The variant of the D vitamin that is formed under the skin is known as vitamin D3, or cholecalciferol. This D vitamin is created when the ultraviolet in the sunlight reacts with a type of cholesterol that is found under the skin naturally. The D3 is converted into a more active form of the d vitamin in the liver and is then diverted to where it is needed the most. Some of the D vitamin remains in the liver and kidneys to help reabsorb the calcium from the blood. The rest of the D vitamin is dispersed to the bones to help them retain their calcium and the intestines to aid absorption of calcium from food.





Even though the majority of the D vitamin is formed through the exposure of the skin to sunlight there are some foods that do contain some of the vitamin naturally. This form of the D vitamin is known as vitamin D2, or ergocalciferol. This is used in the same way as the other D vitamins and is the type used to create the majority of D vitamin supplements.

A Guide to the E Vitamin




The e vitamin is extremely important for a variety of functions in the body. A healthy heart needs plenty of the e vitamin as it has been shown to actually prevent heart disease. The e vitamin can also help contain any existing heart disease and stop it from getting worse.





E vitamin is also vital in protecting the cell membranes from the harmful free radicals that are present in the body. Without e vitamin, amongst others, the cell membranes would be damaged and this could lead to serious health problems, including cancer. The reason that the e vitamin is so effective against free radicals is that it is fat soluble so it can be absorbed into the cell membranes. The e vitamin is therefore essential for the immune system.





The recommended daily amount of the e vitamin that a person requires depends on their body weight. This is connected to the fact that the more fat a diet contains then the more of the e vitamin that is needed. However, the only foods that really contain any reasonable amount of the e vitamin are vegetable oils, seeds, wheat germ, and nuts. It is for this reason that most people should take some form of e vitamin supplement.





A deficiency of the e vitamin does not affect a person immediately. In fact, it can take months for the effects of insufficient e vitamin to be detected. After years of e vitamin deficiency there may e some detectable damage to the nerves of the spinal cord or retina of the eye but this is very rare. Most people obtain enough e vitamin from a normal diet but it is essential that the food that a person eats contains a little fat to help with the absorption of the e vitamin.





There are a few medical conditions that may lead to a deficiency of the e vitamin and may require the person to take e vitamin supplements. Cystic fibrosis causes a person to be unable to digest fats well which leads to less of the e vitamin being absorbed. Crohn’s disease causes to lower absorption rates of the e vitamin and a supplement may be necessary. Some forms of liver disease can also lead to problems absorbing the e vitamin, especially through the intestine. Of course, as fat is required to help absorb sufficient amounts of the e vitamin, anyone on an extremely low-fat diet will need to discuss their options for increasing the amount of e vitamin that their body needs.

All About Vitamin A




Vitamin A was given the first letter of the alphabet for a name because it was the first vitamin to be discovered. It was found that vitamin A has a large number of uses in the body including keeping eyes healthy, aiding cell growth and also helping boost the immune system. However, vitamin A is not only absorbed directly but it is also created by the body by converting beta carotene into vitamin A.





Vitamin A itself is found in a number of foods such as eggs, milk, liver and meat. Beta carotene that the body can convert into vitamin A is found in many fruits and vegetables, especially the red, orange and green coloured ones. The most important point to remember that consuming too much pure vitamin A can be toxic. It is essential not to exceed the recommended daily allowance for vitamin A. The actual recommended allowance of vitamin A varies depending on a person’s age, sex and other factors. While the actual amount of vitamin A consumed may be toxic if the recommended daily allowance is exceeded, there is a far higher limit to how much beta carotene can be consumed. Therefore it is advisable to concentrate on obtaining the greatest amount of beta carotene which the body can then convert to vitamin A, rather than consuming vast quantities of pure vitamin A rich foods.





Many people will remember being told that eating lots of carrots helps you to see in the dark and that is down to the vitamin A that is produced from the high levels of beta carotene that are found in the vegetables. Other foods which have high levels of beta carotene that can be converted to vitamin A include tomatoes and dark green leafy vegetables, such as spinach. Beta carotene is not only used to form vitamin A, but it is also a powerful antioxidant in itself. None of the beta carotene that is absorbed is wasted as any excess after conversion to vitamin A has taken place is used to fight the harmful free radicals within the body. Vitamin A also helps fight infections and illnesses by helping tissues that line various parts of the body, including the eyes, mouth, nose, throat and lungs, to grow and also to repair them if they are damaged to prevent infection. Children also need plenty of vitamin A to help their bones and teeth to develop properly.

An Overview of the B5 Vitamin




The B5 vitamin is also known as Pantothenic Acid. The B5 vitamin is the most prolific of all the vitamins and is found in every type of food. In fact, it is impossible for a person to consume less B5 vitamin than they need. That means that there is no little possibility that a person can have a B5 vitamin deficiency. For this reason, there is actually no recommended daily amount that health professionals can state as everyone obtains more than enough from their normal food consumption. However, even though there is no need to calculate a recommended daily allowance it does not mean that the B5 vitamin is not vital for a healthy body and mind. In fact, the B5 vitamin is essential for turning food into energy amongst other functions. The B5 vitamin is responsible for taking the fats and carbohydrates into energy.





Some B5 vitamin can be found in almost every food whether it is animal or vegetable. Obviously there are some sources of the B5 vitamin that are better than others but a balanced diet will provide more than enough. The foods with the highest B5 vitamin content are organ meats, salmon, eggs, beans, milk, and whole grains. It is worth noting that the B5 vitamin is lost when grains are milled into flour and tends not to beaded back in. Therefore, processed grain foods such as bread, pasta, rice, breakfast cereal, and baked goods are not good sources of the B5 vitamin.





The B5 vitamin is the most effective when it is combined with other B vitamins especially thiamin or B1, riboflavin or B2, niacin or B3, pyridoxine or B6, and biotin. Along with these other B vitamins, the B5 vitamin is an integral part in a number of processes. The most important of these is the production of energy from food that is consumed and this is known as the Kreb’s cycle. The B5 vitamin is also required for releasing energy from fats.





Interestingly, the B5 vitamin is also considered to be helpful in reducing stress. This is chiefly due to the fact that during periods of stress, the body produces more of certain hormones such as adrenalin and these require the B5 vitamin. There are many theories as to the benefits of the B5 vitamin but there is no need for the majority of people to actively seek out foods that are high in B5 as they are likely to be consuming far more than is needed already. There are no adverse effects to consuming too much B5 vitamin.
